The types of roots present in mustard plant is
1 Fibrous roots
2 Adventitious roots
3 Tap roots
4 Nodulated roots
Explanation:
C Tap roots system is present in mustard plant. It is main root of a primary root system. It is growing vertically downward and gives off small lateral roots. - Fibrous root system is opposite of a tap root system. It is usually formed by moderately branching roots growing from the stem. - Adventitious roots include those formed on stem and leaf cutting and those produced by air layering. Nodulated roots are generally found on the roots of leguminous plants like beans, peas etc. Nodules are symbiotic relationship between leguminous plants and \(\mathrm{N}_{2}\)-fixing bacteria rhizobium.

The quiescent centre in root meristem serves as a:
1 Site for storage of food which is utilized during maturation
2 Reservoir of growth hormones
3 Reserve for replenishment of damaged cells of the meristem
4 Region for absorption of water.
Explanation:
C A zone of inactive cells is present in the central part of the root apex is called quiescent centre. The cells of the quiescent centre have a lower concentration of the proteins, DNA and RNA and these are maintained at a lower mitotic activity. - It is responsible for providing the cells to the root apical meristem during the injury or the heavy growth period.

Which one of the following conditions in seen in the roots of a plant having submerged assimilatory roots and spongy petioles?
1 Triarch
2 Monarch
3 Tetrarch
4 Diarch
Explanation:
B Monarch is a condition found in roots of a plant having assimilatory submerged roots and spongy petiole and stele with one xylem Ex:- Trapa natans. Tetrarch- The stele with 4 xylem strands. Ex:- Gossypium. Triarch- The stele with 3 xylem strands. Ex:- Pisum. Diarch- Stele with two xylem strand. Ex:- Nicotiana.

Quiescent centre is the zone of :
1 least mitotic activity in the root apex
2 least mitotic activity in the shoot apex
3 maximum mitotic activity in the root apex
4 maximum mitotic activity in the shoot apex
Explanation:
A Quiescent centre is the zone of least mitotic activity in the root apex. - The quiescent centre of roots consists of a rarely dividing pool of stem cells within the root apical meristem.

1 e, d, a, b, c
2 c, d, a, b, e
3 b, d, a, c, e
4 d, b, a, e, c
5 Release of bacteria into cortical cells
Explanation:
D When bacteria Rhizobium is grow on susceptible aria of root hair and the start divide. Then the infection of root hairs causes the curling of root hair Than Rhizobium bacteria go into innercortex and inner cortical and pericycle cells start to divided and the division of cortex and pericycle made a root nodules Than the root nodules start to release of sugar and aminoacids by legume root.
