B Correct answer
Explanation

Isotype (in plant scientific classification) A plant example that is a copy of or fundamentally the same as the sort example and can be utilized as a source of perspective example if the sort example is lost.

So, the correct option is 'Isotype'.

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.
