C Substances synthesized during growth are protoplasmic and apoplasmic. Protoplasmic is a living part of a cell that is covered by a plasma membrane. Protoplasm is mixture of small molecules such as ions, amino acid etc. Apoplasmic are non-living material. They are formed by the cell which become component of tissues.

Plant growth is:
1 limited
2 unlimited
3 diffused
4 irretic
Explanation:
B Plant growth is unlimited. Plant growth can be understand as the increasing of plant mass or volume without formation (with formation) of new structures such as cells, tissues or cell organelles. Primary growth in the plant is a result of rapidly dividing cell.

Quiescent center occurs in
1 at the tip of root apex
2 at shoot apex
3 just below the tip of root apex
4 just below the tip of shoot apex
Explanation:
A Quiescent center occurs at the tip of root apex. It is basically found in the root behind a region of meristematic activity and cell. Quiescent acts a strong resistance towards ionising radiation.

If the shoot apex of any young plant growing in a pot, is cut off, which of the following events are more feasible to occur?
1 the remaining upper leaves will increase in area
2 the axillary buds in the remaining upper leaves will grow faster
3 Regeneration of apical bud will occur
4 The plant dies
Explanation:
B When we cut the shoot apex the axillary buds are developed and grow more rapidly. This method is used to obtain tall and bushy plants. Removal of shoot apex is called as topping and growing of axillary buds called is suckering.

Substances synthesized during growth are
1 protoplasmic
2 apoplasmic
3 both (a) and (b)
4 nucleic acid
Explanation:
C Substances synthesized during growth are protoplasmic and apoplasmic. Protoplasmic is a living part of a cell that is covered by a plasma membrane. Protoplasm is mixture of small molecules such as ions, amino acid etc. Apoplasmic are non-living material. They are formed by the cell which become component of tissues.
