what are the three main organs of a plant?

Plant organs include their roots, stems, leaves, and reproductive structures. Each plant organ performs a specialized task in the life of the plant. Roots, leaves, and stems are all vegetative structures.

Vegetative organs of plants is responsible for physiological, morphological function, such as photosynthesis, vegetative growth etc. On the other hand reproductive organs are responsible for reproduction or increase of number of plants.

The Parts of a Leaf Most leaves have two main parts: (1) the blade and (2) the petiole, or leafstalk. The leaves of some kinds of plants also have a third part, called the stipules.

The leaves perform three main functions such as manufacture of food, interchange of gases between the atmosphere and the plant body and evaporation of water.

The three primary parts of the plant's vascular system are the xylem, phloem and cambium.

The xylem tissue moves water and nutrients to various parts of the plant such as shoots and leaves. Its major components include xylem parenchyma, xylem fibers, tracheids, and xylem vessels. The xylem parenchyma is comprised of parenchyma cells. Parenchyma cells are the only living cells in the xylem.

['External plant structures such as leaves, stems, roots, flowers, fruits and seeds are known as plant organs. ... ', "As a plant's reproductive part, a flower contains a stamen (male flower part) or pistil (female flower part), or both, plus accessory parts such as sepals, petals, and nectar glands (Figure 19)."]

There are various types of plant cells which include: parenchyma cells, sclerenchyma cells, collenchyma cells, xylem cells, and phloem cells. Parenchyma cells are the major cells of plants.

Terrestrial plants have root and shoot systems. The types of roots are taproot, fibrous and adventitious. Shoot system includes stem, leaves and flowers. Leaves and stems are classified as vegetative parts of a plant while flowers and fruits are reproductive parts.

A plant is made up of many different parts. The three main parts are: the roots, the leaves, and the stem. Each part has a set of jobs to do to keep the plant healthy. The roots absorb water and minerals from the soil and anchor the plant in the ground.

They contain everything necessary for the growth and development of a new plant. The three primary parts of a seed are the embryo, endosperm, and seed coat.
