Which of the following plant cells will show totipotency?
1 Sieve tubes
2 Xylem vessels
3 Meristem
4 Cork cells
Explanation:
Exp:C Totipotency is the ability in which cells can get specialized into any type of cells. Meristems shows the totipotency because xylem vessels and cork cell are dead while sieve tube cells do not possess nuclei. The primary meristem present from the beginning and throughout the life.

Mowing grass lawn facilitates better maintenance because
1 wounding stimulates regeneration
2 removal of apical dominance and stimulation of intercalary meristem
3 removal of apical dominance
4 removal of apical dominance and promotion of lateral meristem.
Explanation:
Exp:B Apical dominance occur in the presence of auxin and it is a common observation in vascular plants. If apical meristem is intact and growing, the growth of lateral tips is suppressed. According to Thimann and skoog the auxin, synthesized in apical meristem, is translocated downwords and inhibits the growth of lateral tips. That is why moving grass lawns facilitate better maintenance because of removal of apical dominance and stimulation of intercalary meristem.

The meristem, which develops into a primary vascular tissue is
1 protonema
2 promeristem
3 ground meristem
4 procambium
Explanation:
Exp:D Procambium - It occurs below the protoderm and gives rise primary xylem, primary phloem and intrafascicular cambium.

Meristematic cells have:
1 thick cell wall and large intercellular spaces
2 thick cell wall and no intercellular spaces
3 thin cell wall and large intercellular spaces
4 thin cell wall and no intercellular spaces
Explanation:
Exp:D Meristematic cells have thin cell wall without intercellular spaces as they keep actively dividing. Meristematic cells are dense cytoplasm, small vacuoles and large nucleus. Meristematic cell walls are thin and made up of primary cell wall containing cellulose.

The histogens are classified on the basis of :
1 cells they contain
2 cells they give rise to future tissue
3 meristematic activity
4 cell division
Explanation:
Exp:B Root apical meristem consist of three cell initiating region called histogen. Which classify into three parts. Dermatogen which form epidermis, periblem form cortex and plerome forms vascular bundle.
