What structures are the body of plants made of?

There are many kinds of plants in nature, and there are more than 500,000 known species now. There are lower plants with simple morphological structures, such as single-celled chlorella and yeast.

Multicellular kelp, Poria cocos.

Wait; There are higher plants with complex morphological structure, roots, stems and leaves, such as ferns, pines, sunflowers, etc. In higher plants, a large group of plants that can flower and bear fruit to form seeds and reproduce with seeds is called seed plants. Among these plants, there are tens of thousands of plant species, which contain various alkaloids, polyglycosides, terpenoids, organic acids, amino acids.

Hormones, antibiotics.

The main ingredients of medicine such as tannins, people refer to such plants collectively as medicinal plants according to the use of such plants. Seed plants can generally be divided into six parts: roots, stems, leaves, flowers, fruits, and seeds, which are the six organs of the seed plant body. Plant organs are generally divided into two categories based on their physiological functions:

A group of vegetative organs, including roots, stems and leaves, together play the role of absorbing, producing and supplying the nutrients needed for food, so that the plant body can grow and develop. The other type is called reproductive organs, which include flowers, fruits, and seeds, and they mainly play the role of reproducing offspring to continue the race. The various organs of plants are interdependent and unified in the life activities of plants, and they are closely related in physiological functions and morphological structure.

The body of a plant is made up of six parts: roots, stems, leaves, flowers, fruits, and seeds.

Among them, roots, stems, and leaves are the vegetative organs of plants; Flowers, fruits, and seeds are the reproductive organs of plants.

The tissues in the plant that store inorganic matter are mainly vegetative tissues. The vegetative tissue is characterized by large cells, thin cell walls, large vacuoles, loose arrangement, and rich storage of nutrients. The main feature of this tissue is that it is composed of living parenchyma cells, so it is also called parenchyma, which generally includes absorption tissue, assimilation tissue, storage tissue, ventilation tissue and delivery cells, which are responsible for absorption, assimilation, storage, ventilation, transmission and other functions.

Types of vegetative tissue:1.Assimilated tissues, parenchyma that can carry out photosynthesis, have chloroplasts such as mesophyll in cells.

2.Storage tissues, parenchyma tissues that store rich nutrients in cells, such as fruits, seeds.

3.Aerated tissues, which are often found in aquatic or wet plants, have particularly well-developed intercellular spaces, forming large air cavities or penetrating the airways.

4.Water-storing tissues, drought-tolerant and pulpy cacti are generally present, and the cell walls of such tissues are thin, with large vacuoles, which are filled with water.

The body of a flowering plant is divided into six parts: roots, stems, leaves, flowers, fruits, and seeds.

1. The formation and germination of seeds refers to the process of angiosperms completing double fertilization, the fertilized egg develops into an embryo, and the fertilized polar nucleus develops into the endosperm.

2. The growth and development of the plant refers to the growth of the seedling after a period of time to become a plant with roots, stems and leaves. When the plant grows and develops to a certain stage, it begins to form flower buds, followed by flowering and fruiting.

The body of a plant is generally composed of roots, stems, leaves, fruits, and flowers.

Roots are an important part of the plant's body and are mainly responsible for absorbing water and nutrients, holding the plant in the soil. Through the branching and extension of the roots, the plant is able to take root in the soil, absorbing water and nutrients from the soil, while also providing support to stabilize the plant body. The stem is the main supporting structure of the plant, responsible for connecting the roots and leaves, and is responsible for the growth and development of the plant.

The main function of the stem is to provide support and transport water and nutrients. The morphology of the stem is diverse, and it can adapt to different ecological environments and growth habits.

Leaves are the main respiratory organs of the plant body and the site of photosynthesis. Leaves absorb light energy mainly through leaf ruler regreening, and photosynthesize, converting carbon dioxide and water into nutrients and oxygen. The fruit is the plant's main reproductive and shed-dispersed structure, attracting animals and other spreaders by wrapping the seeds and providing food.

Flowers are the organs of reproduction that are mainly responsible for pollen dissemination and seed production. Flowers are morphologically diverse, with petals and stamens attracting insects and other pollinators for the purpose of pollination and pollination. It plays an important role in the evolution and reproduction of plants, and has an important impact on the species diversity and survival ability of plants.

Functions and adaptations of the plant body

Roots are responsible for absorbing water and nutrients from the soil and fixing the plant's body. The stem acts as a support and conduction, allowing the plant to expand and branch. Leaves are a key part of plants for photosynthesis and respiration, absorbing light energy through chlorophyll and using it for photosynthesis to produce nutrients and oxygen.

The fruit is the structure of the plant for seed protection and dispersal. Flowers are a key mechanism for plant reproduction and dispersal, achieving pollen dispersal and seed dispersal by attracting pollinators.

In summary, the body of a plant is composed of roots, stems, leaves, fruits, and flowers, each of which has different functions and adaptations to adapt to different ecological environments and survival needs. Together, these parts make up the size and structure of the plant, allowing it to carry out physiological activities such as nutrient absorption, growth and development, photosynthesis, and reproduction and dissemination. The diversity and adaptability of plant bodies not only demonstrates the wonders of the natural world, but also gives people a deep reflection on the vitality and evolution of plants.
