NEET BIOLOGY

Detailed explanation-1: -For the process of photosynthesis, raw materials should be transported to the leaves. For transport in plants, they need a transport system to move food, water, and minerals around because for them no heart, no blood, and since these plants do not have a circulatory system, transportation makes up for it.

Detailed explanation-2: -Their transport system is slow compared to that of other species as the majority of plant cells are dead and they don’t possess any pumping machinery such as the heart. In addition, they are non-motile organisms and thus do not have a high energy requirement.

Detailed explanation-3: -Transport of materials is necessary in both plants and animals as every cell needs a regular supply of nutrients and oxygen for releasing energy through respiration. The food that we eat is broken down into smaller components to be absorbed by the cells.

Detailed explanation-4: -Nutrients are transported along with water to the entire plant via the vascular tissue called xylem. The vascular tissue for the transport of food to the various parts of the plant is phloem. A lot of water is lost by plants in the form of vapour through stomata during transpiration.

Detailed explanation-5: -Minerals and water are carried from the soil to the plants via xylem cells in plants. Salts in the soil are absorbed by roots and subsequently translocated upwards with water via the xylem. The stem, roots, and leaves all have linked xylem cells that form a conducting channel that reaches all sections of the plant.
