Plant morphological characteristics, which plants with special morphology do you know?

Use a search to find the inflorescence refers to the situation that the flowers are arranged on the flower branches, the simplest form of the inflorescence is a solitary flower, if there are multiple flowers arranged on the inflorescence axis, the type of inflorescence can be divided into the following two ways: 1. According to the structure of the inflorescence, it can be divided into 1Racemes Most flowers have pedicles and are born on unbranched inflorescence axes, called racemes.

Such as cruciferous plants. 2.Spikes The flowers are sessile, and most of the flowers are arranged on an unbranched inflorescence axis, called spikes.

For example, many plants in the Poaceae, Cyperaceae, Amaranth and knotweed species have spike-like inflorescences. 3.Inflorescence A spike-like inflorescence composed of unisexual multiflories, usually drooping, is called a inflorescence.

Such as mulberry, poplar, willow, etc. 4.Umbrella inflorescence The flowers are peduncled, arranged near the top of the inflorescence axis, the peduncle at the lower end is longer, and the flowers are shortened upward, and the flowers are located on an approximate plane, such as hemp leaf hydrangea, hawthorn, etc.

For example, several umbrella inflorescences are arranged near the top of the general axis of the inflorescence, which is called a compound umbrella inflorescence, such as meadowsweet. 5.Inflorescences are sessile, and most of the flowers are born on a receptacle, forming an inflorescence like a head.

Such as plants of the Asteraceae family. 6.Panicles There are multiple racemes on the inflorescence axis, which resemble cones, and are called panicles or complex racemes.

7.Umbel Inflorescence From the top of one peduncle protrudes multiple peduncles of nearly equal length, and the whole inflorescence is shaped like an umbrella, called an umbel inflorescence. Each small peduncle is called an umbrella peduncle.

Such as spring, point plum. If an umbel regenerates at the top of the peduncle, a compound umbel will be formed, such as a carrot. 8.

The inflorescence of the inflorescence or ** flower opens first, and then gradually opens on both sides, which is called the inflorescence of the umbrella, such as tomato. After each flower, two branches are produced on both sides, and such a polyumbel inflorescence is called bifid polyumbel inflorescence, such as holly and euonymus. Each apical flower of the inflorescence has branches on only one side and belongs to the monofidus inflorescence, such as daylily.

When the lateral branches are always arranged on the same side, so that the tip of the inflorescence is curled into a scorpion tail, called the scorpion tail inflorescence, such as Ximeili Second, according to the order of flower opening can be divided into: 1Infinite inflorescence (centripetal inflorescence) The flowering order is from the lower part of the inflorescence axis to the upper part, or from the edge to the center.

Racemes, spikes, inflorescences, umbels, umbels and capitate inflorescences are all infinite. 2.Finite inflorescence (centrifugal inflorescence) refers to the flower at the very top or center of the inflorescence that blooms first and gradually extends to the lower edge or periphery, like the inflorescence of the umbrella inflorescence is a finite inflorescence.

The encyclopedia came out in one go. There are a few ** that are also good, the Chinese plant image library, and the CVH

I just met one today: the bee waist sprinkled with golden banyan, the leaves are divided into two parts, and the middle is connected by a petiole, which is very chic!

<> it is a very magical variety, it is called Bee Waist Sprinkle Golden Ficus also called Bee Waist Ficus, is a special appearance of the foliage plant, generally only in the southerner area of some botanical gardens to see its figure, is not a common plant, only a very small number of flower friends will raise this plant.

Ficus is a small shrub that can grow into a small tree, the plant does not grow particularly tall, its leaves grow specially, and the edges of the leaves are like waves. Its name is Ficus spp., but it is a species of Variegated Wood, and if you just look at its leaves, it is somewhat similar to Phylla Speck.

The flowers of the golden ficus sprinkled on the waist of the bee, whether it is a male flower or a female flower, are spike-shaped inflorescences, which is the same as the flowers of the variable leaf wood, they are ornamental plants with female flowers and male flowers, and the morphological difference between male and female flowers is also quite large.

The leaves of the bee waist sprinkled with golden banyan are very peculiar, it is a horticultural ornamental variety of variable leaf wood, the leaves seem to be artificially divided into two segments, the most tip of the leaf looks like a small spoon, there will be a slender petiole connected, (the bee waist is to describe the two ends are large, the middle is small, now are used to describe the woman's figure) rarely see plants grow into such a form.

The most peculiar plants are generally common cypress, pitcher plant, sunflower flower, mimosa, stone flower, centenarian leaf, alocasia, flame, gum tree, hydrangea flower, each different plant has different ornamental value

Rafflesia is the largest flower in the world, with flowers up to one meter in diameter. The flowers are large, but the smell is very smelly, and it is a saprophytic plant. Generally grown in tropical areas, Rafflesia only blooms one flower in its lifetime, and the buds still have a fragrance when they first bloom, but the taste after that is a relatively unpleasant rancid smell.

Because of this taste, there is another name called "carrion flower."

Cape's sundew, commonly known as the Cape of Good Hope, is a carnivorous plant that grows in South Africa. The Cape of Good Hope sundew is more effective than the Venus flytrap because it is covered with sticky tentacles that trap insects that land on it. Plants are one of the main forms of life and include trees and shrubs, vines, grasses, ferns, 、..

1. A sub-discipline of botany that studies the development, morphology and structure of plants, and explains the changes in the morphology and high-deficiency structure of various existing plants according to their ontogeny and phylogeny. According to the research object, it can be roughly divided into the morphology of spore plants that produce spores in Mengnian mu, the morphology of seed plants that produce seeds (gymnosperm morphology, angiosperm morphology) and the morphology of vascular plants based on vascular tissue structure.

2. According to the research direction, it can be divided into: comparative morphology to explain the morphological similarities and differences from a comparative point of view, plant systematics to study the phylogenetic evolution and origin of plants, experimental morphology to discover the law of morphological changes through experiments, and morphogenesis to explain the influence of internal and external factors on the formation of plant bodies.

1. Morphological characteristics

The leaves of evergreens can only last for a little over a year (new leaves will grow soon after the old leaves fall off), and the maximum duration is about 40 years (Pinus longaeva). However, few species can keep their leaves present for more than 5 years.

In the tropics, most rainforest plants are evergreen, and as the leaves age and autumn begins, they gradually replace their leaves throughout the year, while species that grow in seasonally dry climates can be both evergreen and deciduous species.

Most plants in temperate climates are also evergreen. But in cold climates, there are almost no evergreens, and the coniferous plants dominate here, because none of the evergreens with broad leaves can tolerate -25 low temperatures.

Second, the use

Evergreens are used to beautify the environment, provide shade, adjust temperature, reduce wind speed, reduce noise, provide privacy, and prevent soil erosion. Cut flowers, dried flowers, and indoor potted plants are placed indoors, and lawns, shade trees, landscape trees, shrubs, vines, and perennial herbs are set up outdoors. Artistic types of living plants include green carvings, bonsai, flower arrangements, and tree walls.

Differences between evergreen and deciduous tree species.

Evergreen and deciduous tree species differ in a range of morphological and physiological characteristics. In general, broad-leaved evergreen species have thicker leaves than deciduous species, and have a larger volume of parenchyma and air space per unit leaf area. They have a larger leaf biomass per unit leaf area and hence a lower specific leaf area.

There was no difference in construction costs between the groups.

Evergreens typically present a larger portion of the plant's total biomass in the form of leaves (LMFs), but they typically have a lower rate of photosynthesis.

The structure of plants is mainly leaves, rhizomes, flowers, fruits and seeds, of which leaves are divided into epidermis, mesophyll and leaf veins, which can carry out photosynthesis for plants, rhizomes are an important part of plant survival, can supply water and nutrients to various branches, and flowers are the places where plant fruits and seeds are formed.

1. Roots and stems

The root is an important place for the whole plant to provide nutrients and water for the plant in the growth process, and it is also an important part of the plant survival that is directly related to the stem, the stem is an important structure that provides water and nutrients to the branches, and it is mainly responsible for supporting the growth of the whole plant, and these two parts are mainly distributed in the lower part of the plant.

2. Leaves and flowers

Leaves are the whole plant's bright sucking place, equivalent to the human respiratory tract, providing sufficient photosynthesis for the growth of the whole plant, flowers are the place where plants form seeds and fruits, and these two also serve as the appearance part of the whole plant, flowers and leaves can enhance the impression of the whole plant width key digging in people's cautious core.

3. Fruits and seeds

Fruit is a product of the growth process of a plant, many fruits can be eaten by people, with a certain economic value, and some fruits are inedible but have a certain medicinal value, seeds are an important part of the reproduction of new life, can be said to be the origin of plant life, these two are also very important in the whole structure.

The leaves of plants are very different, and the leaves of ordinary higher plants are generally composed of three parts: leaves, petioles and petioles, while some plants have no leaves or petioles; Any leaf with the above three parts is called a "complete leaf"; Leaves that lack one or two of these parts (petioles or petioles) are called "incomplete leaves". The morphology of each part of the leaf, especially the leaf, is one of the bases for the classification of plants. The leaves are generally flattened, symmetrical on both sides of the cherry, and are composed of epidermis, mesophyll and veins; Mesophyll is the basic tissue, and the cell contains chloroplasts, which is the main tissue for photosynthesis. And the intercellular space is well developed, with the help of the stomata on the epidermis, photosynthesis is carried out.
