Simple plant without rhizome Leaf category name 50

Lower plants do not have the differentiation of roots, stems, and leaves, such as algae plants, lichens, etc.

Mosses, lichens. Cucurbitbit, moss, and so on.

Algae do not have rhizomes and leaves, and mushrooms do not.

Summary. Hello Roots, stems, leaves, flowers, fruits, and seeds do not have algae, lichens, and fungi plants, which belong to lower plants (according to the two worlds and the three worlds, fungi belong to plants).

Hello Roots, stems, leaves, flowers, fruits, and seeds do not have algae, lichens, mushrooms, and fungi plants, which belong to the lower plant crypts (according to the two worlds and the three worlds, sclerotinia belong to plants).

Bryophytes do not possess flowers, fruits, and seeds, but have differentiated roots and stems, and have false roots; Ferns are suspected of having roots, stems, and leaves, and have no flowers, fruits, and seeds; Gymnosperms and angiosperms have roots, stems, leaves, flowers, and seeds, angiosperms have fruits, gymnosperms are considered to have no fruits, and even organs like pine towers, pine balls are not considered fruits by the calendar. Bryophytes, ferns, gymnosperms, and angiosperms are all higher plants. <>

Thank you. Plants are one of the main forms of life, including trees, shrubs, vines, grasses, ferns, and familiar organisms such as green algae and lichens. Plants can be divided into seed plants, bryophytes, ferns, etc., and it is estimated that there are about 450,000 species in existence.

Most of the energy of green plants is obtained from the sunlight of the permeable rock through photosynthesis, and temperature, humidity, light, and fresh water are the basic needs of plants for survival. Angiosperms have six major organs: roots, stems, leaves, flowers, fruits, and seeds.

Green plants have the ability to photosynthesize - with the help of light energy and chlorophyll, under the catalysis of enzymes, they use water, inorganic salts and carbon dioxide for photosynthesis, release oxygen, and produce organic matter such as glucose for plant use. <>

In nature, all organisms that have branches and branches are living beings. Organisms should be divided into several kingdoms, and the organisms that can live sedentically and autotrophically are called the plant kingdom, referred to as plant belts.

The stems of the plant are divided into above-ground stems and underground stems.

Aboveground stems are further divided into: leafy stems, tendrils stems, fleshy stems, and stem spines.

Underground stems are further divided into: rhizomes, tubers, bulbs, and bulbs.

Leaf-like stems include: cactus, false leaf tree, etc.

The tendril stems are: pumpkin, cucumber, grape, etc.

Succulent stems are: succulent, etc.

Stem thorns are: hawthorn, soaphorn, etc.

Tubers are: potatoes, etc.

The rhizomes are: lotus root, ginger, etc.

Bulbs are: water chestnut, mushroom, etc.

Bulbs are: onions, garlic, etc.

The role of plant rhizomes.

Conduction: Water and inorganic salts absorbed by the root hairs are transported along the stem mainly from the bottom up but in plants with weeping branches.

Supporting effect: The stem relies on the well-developed mechanical organization inside to withstand the full weight and pressure of branches, leaves, flowers and fruits.

Storage: Starch, sugar, fat, and protein can be stored in the stem for plant utilization.

Reproduction: The use of stems and techniques for cuttings, strip nucleus clearing, grafting, and the use of underground stems for propagation has been an important measure in afforestation and crop cultivation.

1. The lotus flower is also called lotus, and its stem is the lotus root that we are most familiar with.

The stem is hollow, a grooming tissue used to transport oxygen, and there is also a rich starch, and the leaves belong to the water-stopping leaves, that is, the leaves need to be lifted high by the petiole over the water surface, and after passing the water surface, they are flattened into shield-shaped, round leaves.

2. Water lilies. The stems of water lilies are not much different from those of lotus flowers, but the leaves do vary greatly. The leaves of the water lily are floating, that is, the leaves float on the surface of the water, rather than being lifted high above the water level by the petioles.

In addition to this, the leaves are not round leaves, but heart-shaped leaves because there is a deep crack in the leaves.

3, Sichuan Sanqi.

It is a vine climbing plant, and its stem is slender and hard, and it can be wrapped around the appendages while growing, and the leaves are unique heart-shaped, which is very beautiful. The blades come in small to medium sizes and come in different sizes.
