Phloem contains
(1) dead matter in it know as bast
(2) long and narrow sclerenchymatous fibres
(3) companion cell, which are living, thin-walled, narrow.
(4) cells which are long and tubular with lignified cell wall
1 1,2 and 3 are correct
2 1 and 2 are correct
3 2 and 4 are correct
4 1 and 3 are correct
Explanation:
Exp:D From the above Statement is (d) option a correct answer. Phloem contains dead matter in it which is known as bast. It contains companion cells, which are living, thin- walled, narrow. Phloem fibres also called as 'bast fibres' are the only dead cells present in the phloem. Phloem parenchyma and companion cells are elements of phloem and both are living cells and thin walled. Hence, statement 1 and 3 are correct.

Collenchyma is
1 living and contains protoplasm
2 dead and hollow
3 dead and filled with reserve food
4 living and contains no reserve food
Explanation:
Exp:A Collenchyma is living and contains protoplasm. It is a supporting tissue composed of more or less elongated living cells with unevenly thickened, nonlignified primary walls. collenchyma tissue are found below the epidermis of stem and around veins of leaves in plants.

Which of the following plant tissue cannot be used as explant in tissue culture?
1 Meristem
2 Parenchyma
3 Sclerenchyma
4 Collenchyma
Explanation:
Exp:C Sclerenchyma tissues cannot be used as explants in tissue culture because sclerenchymatous tissue have lignified sencondary wall and dead in nature. Meristem, parenchyma and collenchymas are living cells.

P-proteins are associated with
1 sieve tube elements
2 xylem parenchyma
3 trichomes
4 tracheids and vessels
Explanation:
Exp:A \(\mathrm{P}\) - proteins are associated with sieve tube elements'. It is also known as phloem protein. Pprotein aggregates at the sieve plate when the sieve element is disrupted, preventing the passage of phloem exudates the function of P-protein is sealing mechanism on wounding along with calluse and it is also related with conduction of food.

Which of the following tissues consist of living cells?
1 Vessels
2 Tracheids
3 Companion cell
4 Sclerenchyma
Explanation:
Exp:C Companion cells consists of living cell. The companion cells are specialized parenchymatous cells in the phloem tissues of the angiosperm. They are nucleated living cells with several ribosomes, plastids and mitochondria, phloem parenchyma and companion cells are element of phloem and both living cells.
