Water and dissolved minerals get into the root hair of a plant by a process called A and enter the conducting tissue B. The 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 plant is called F. (a) What are (i) A (ii) B (iii) C (iv) E, and (iv) F ? (b) Which tissue is made up of living cells : B or E ? (c) Name one substance (other than oxygen) which is transported by tissue A in the human body. (d) Which two components of tissue A are the cells without nucleus ? (e) Name any two organisms (animals) which do not have liquid like A in their body.

Assertion. Sieve tube members have abundant cytoplasm but there is no nucleus. Reason. Nucleus is present in companion cell.
