Water and dissolved minerals get into the root hair of a plant by a process called A and enter the conducting tissue B. The process C helps the water and dissolved minerals to move up through the tissue B in roots and stem, and reach the leaves of a plant. In the leaves food is made by a process D. This food is then transported to all the parts of a plant through tissue E. The process of distributing food made in the leaves to all the parts of the plants is called F.
(a) What are (i) A (ii) B (iii) C (iv) D (v) E, and (vi) F?
(b) Which tissue is made up of living cells : B or E?
(c) Which tissue, B or E, contains sieve tubes?
(d) Which tissue, B or E, contains tracheids?

Solution

(a)
(i) The process by which water and dissolved minerals get into the root hair of a plant is known as diffusion. Hence, A is diffusion.
(ii) The water and dissolved minerals are absorbed by the cells of the root hair, which enter the conducting tissue known as xylem. Hence, B is xylem.
(iii) Transpiration helps in transporting water and dissolved minerals to move up through the xylem tissue (B) in the roots and the stem, and reach the leaves of a plant. Hence, C is transpiration.
(iv) In leaves, the food is prepared by a process known as photosynthesis. Hence, the process D is photosynthesis.
(v) The food synthesised by the leaves of a plant is transported to all the parts of a plant through tissue phloem (E). Hence, E is phloem.
(vi) The process of distributing (or transporting) food made in the leaves to all the parts of the plant is called translocation. Hence, F is translocation.

(b) B represents xylem, while E represents phloem. Out of these, phloem (E) is made of living cells.

(c) E (phloem) contains sieve tubes.

(d) B (xylem) contains tracheids.

The transport system in plants consists of two kinds of tissues X and Y. The tissue X is made up of living cells and consists of two components A and B. The component A has tiny pores in its end walls and contains only cytoplasm but no nucleus. On the other hand, component B has cytoplasm as well as nucleus. The tissue Y is made up of dead cells and consists of two components C and D. The component C has open ends whereas component D does not have open ends. In flowering plants, either only C or both C and D transport water but D is the only water conducting tissue in non-flowering plants.

The liquid connective tissue A circulates in our body continuously without stopping. This tissue contains a pigment B which imparts it a colour C. The tissue A consists of four components D, E, F and G. The component D fights infection and protects us from diseases. The component E helps in the clotting of tissue A if a person gets a cut. The component F is a liquid which consists mainly of water with many substances dissolved in it and component G carries oxygen from the lungs to all the parts of the body.
