Identify the given figure and select the correct option for the parts labelled as A, B and C

Options

A. (a) C represents the cells which are replaced by albuminous cells in non-flowering plants such as gymnosperms
B. (b) A represents phloem parenchyma, which is absent in most monocots
C. (c) B represents the cells which become dead on maturity
D. (d) all of these

Answer

A

Explanation

In the given figure companion cells are labelled as 'C'. These cells are narrow, elongated and thin-walled living cells. They lie on the sides of sieve tubes and are closely associated with them through compound plasmodesmata. Companion cells are replaced by modified parenchyma cells (albuminous cells) in non flowering plants 'A' represents sieve plate and 'B' represents sieve tube cell.
