Plant Transport and Physiology

Walls of a cell exert pressure on the cell content.

The elaters help in the dispersal of spores as they form wing like structure.

Boron deficiency causes drought spot in apples characterised by the softening of tissues and internal cork diseases.

Capillary action is the ability of a liquid to flow in narrow spaces without the assistance of, or even in opposition to, external forces like gravity, which helps water move up plant stems.

Phloem is the vascular tissue in plants responsible for the translocation of organic nutrients, primarily sugars, from the leaves to other parts of the plant. Xylem is the tissue responsible for water conduction.

Xylem is the specialized plant tissue that transports water and dissolved minerals from the roots to the rest of the plant. Phloem is responsible for transporting food.

Sclerenchyma cells have thick, lignified walls that provide structural support and rigidity to the plant body. They are typically found in mature parts of the plant that are no longer growing.

The correct answer is option (3).

process by which moisture is carried through plants from roots to small pores and its evaporated out is known as transpiration.

Food is mainly stored in the form of starch.

Stomata does all the three activities

Plant organs show rheotactic movement in response to water current.

Thses roots are found in aquatic plants. These roots develop from the nodes of the floating branches. The roots are spongy and are colourless. These roots are present above the level of water. As these roots are spongy and soft they store air in them, which help the plant in floating. They also help in respiration process.

In harmful levels of sunlight, specialised leaves, opaque or partly buried, admit light through translucent windows for photosynthesis at inner leaf surfaces. For e.g., Fenestraria.

Parenchyma cells helps in the formation of adventitious buds, it aids in the water storage in succulent plants.
