Plant Transport and Physiology

This is the correct option. In plants, transpiration occurs through stomata by the process of diffusion.

This is the correct option as this statement is false. Movement of minerals and water does not take place from the leaves to the other parts of plants.

In a human body, there are four types of blood vessels, is a false statement. There are three types of blood vessels - arteries, veins and capillaries. Thus, this is the correct option.

Transpiration is the loss of water in vapour form from the leaves in plants. Circulatory system is the movement of substances throughout the body with the help of blood. Diffusion is the movement of particles from a high concentration area to a low concentration area until they are spread out evenly.

Yes, regarding guard cells both the above options are correct.

A bud is an undeveloped or embryonic shoot and normally occurs in the axil of a leaf or at the tip of the stem. Once formed, a bud may remain for some time in a dormant condition, or it may form a shoot immediately where as a seed is a small embryonic plant enclosed in a covering called the seed coat, usually with some stored food. It is the product of the ripened ovule of gymnosperm and angiosperm plants which occurs after fertilization and some growth within the mother plant.

Stomata are tiny pores found on the surface of leaves that facilitate gas exchange during photosynthesis. They allow carbon dioxide to enter the leaf and oxygen/water vapor to exit, regulated by guard cells.

The tiny pores on the surface of leaves help in transpiration.

It is the pipeline that carries water and nutrients from roots to leaves.

Sliced leaves reduce wind resistance.

Parenchyma is a versatile living tissue involved in storage, photosynthesis, and providing basic structural support. Flexibility, which allows plant parts to bend without breaking, is specifically provided by collenchyma tissue. Collenchyma cells have characteristic wall thickenings that parenchyma cells lack.

Phloem is the vascular tissue responsible for transporting organic nutrients, primarily sucrose, from the leaves to other parts of the plant. Sieve tubes are the main conducting elements within the phloem that facilitate this transport. Xylem components like vessels and tracheids are instead responsible for water and mineral transport.

Transpiration is the process where plants lose water in the form of vapor. This primarily occurs through small pores called stomata located on the surface of leaves. Phloem and sclerenchyma are structural or transport tissues not directly responsible for gas exchange or vapor loss.

Desert plants, or xerophytes, must conserve water in arid environments. A thick epidermis, often covered by a heavy waxy cuticle, helps reduce water loss through evaporation. Other adaptations like sunken stomata or fleshy stems also contribute to water conservation.

Xylem is responsible for the upward conduction of water and minerals from the roots to the rest of the plant. Its thick, lignified cell walls also provide significant mechanical strength and structural support to the plant body.
