The meristem that is parallel to the longitudinal axis of the plant is ____________.

  1. Procambium

  2. Intercalary meristem

  3. Phellogen

  4. Apical meristem
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A. Procambium is a plant tissue that came from the apical meristem which made the vascular bundles i.e, the xylem and the phloem.

B. Intercalary meristems are residual apical meristems that exist at the nodes and internodes which increases the length of the plant.

C. Phellogen is also famous as cork cambium which is a lateral meristem. It increases the girth of the plant.

D. The apical meristem is placed at the root and shoots tip. It helps in the primary growth of a planet by increasing the length of the plant.

The lateral meristem which occurs on the lateral side of the longitudinal axis stem. It is parallel to the longitudinal axis and also responsible for increasing the girth of a plant (secondary growth).

So, the correct answer is 'Phellogen'.

The correct option is C.

Study the following lists

List-I List-II
(A) Coleorha (I) Development of sporophedirely from gametophewithout intervention ofgametes
(B) Apogamy (II) Development of gametophedirectly om sporophewithout the involvement ofreduction division
(C) Indusium (III) An unbranched columnsstem with a crown of leaves
(D) Caudex (IV) Protedive covering of radical
(V) Protective structure of a sorus

The correct is match:

  1. A B C D

    V II IV I

  2. IV I V III

  3. III V II IV

  4. II III I V
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Coleorhiza is the protective covering of the radicle (IV), Apogamy is development without gametes (I), Indusium is the protective structure of a sorus (V), and Caudex is an unbranched stem (III). This matches IV, I, V, III.

Papaya is a dioecious plant. This condition prevents.

  1. Both autogamy and geitenogamy

  2. Only autogamy

  3. Only xenogamy

  4. Geitonogamy
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Dioecious plants have male and female flowers on separate individuals. This physical separation prevents both autogamy (self-pollination within the same flower) and geitonogamy (pollination between flowers on the same plant).
