The primary functions of plant stem are: Plant stems aid in the elevation and support of leaves, fruits and flowers. The stems give the plant a place to hold its flowers and fruits and also keep the leaves in the light. The stem tendrils of cucumber, grapevine and watermelon are used as support structures. It is also a nutrient-storing structure.
Functions of a stem in a plant: The stem belongs to the shoot system and can vary in length, and diameter, and maybe soft or woody. The stem is a link between the roots and the other parts of the plant such as leaves, fruits, and flowers. It provides support to the leaves, fruits, and flowers.
Support: Primary function of the stem is to hold up buds, flowers, leaves, and fruits to the plant. Along with the roots, a stem anchors the plants and helps them to stand upright and perpendicular to the ground. Transportation: It is the part which transports water and minerals from the root and prepared food from leaves to other parts of the ...
They are an integral or integrated system that helps the plant in: Anchoring: Roots are the reason plants remain attached to the ground. They support the plant body, ensuring that it stands erect. Absorption: Primary function of the roots is to absorb water and dissolved minerals from the soil.
3. Aerial Stem Modification. In some plants, the aerial part of the stem and buds get modified to perform various functions such as support, climbing, photosynthesis and vegetative propagation. Tendrils – These are coiled and a delicate part, which are used for climbing. They develop from the axillary bud.Examples: grapevines, watermelons ...
Functions of Stomata. The main functions of stomata are: Gaseous exchange- Stomatal opening and closure help in the gaseous exchange between the plant and surrounding. It helps in transpiration and removal of excess water in the form of water vapour. Stomatal closure at night prevents water from escaping through pores.
The stem is erect and grows away from the soil towards the light. There is a terminal bud at the apex of the stem. In angiosperms, the shoot is differentiated into nodes and internodes. Young stems are green and photosynthetic. Multicellular hair is present. The stem and branches of mature plants bear fruits and flowers. Different forms of Stem
Plants are immobile and hence have been provided with tissues made up of dead cells, which provide structural strength. They have to endure unfavourable environmental situations like strong winds, storms, floods etc. Plant Tissue System. A tissue is a cluster of cells, that are alike in configuration and work together to attain a specific function.
Each leaf typically has a leaf blade (lamina), stipules, a midrib, and a margin. Some leaves have a petiole, which attaches the leaf to the stem. Getting to Know Plants Class 6 Chapter 7 Science Notes are prepared by the subject experts, which includes short notes, important questions on exam point of view and lot more.
The shoot system refers to the portion of the plant that protrudes above ground level, whereas the root system refers to the portion buried beneath the soil. The essential parts of a plant are: Roots. Stem. Leaves. Flowers. Fruits. The study of plant organ tissue and cellular structure is known as plant anatomy.
