Important Questions on Life Processes
What is (i) tissue X (ii) component A, and (iii) component B?
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.
What is (i) tissue Y (ii) component C, and (iii) component D?
What are (i) A (ii) B (iii) C (iv) D (v) E, and (vi) F?
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 plant is called F.
Which tissue is made up of living cells: B or E?
