Question

Cambium cells divide in which plane
A. Tangential
B. Radial
C. Oblique
D. Anticlinal

Answer 1

Hint: In plants cambium is a tissue, which consists of undifferentiated cells for plant growth and this cambium is formed in the area which is present between xylem and phloem, cambium forms the cells, which results in the secondary tissue, cambium are of different types, they are cork cambium and unifacial cambium, and vascular cambium.

Complete answer: Vascular cambium is the part of the lateral meristem, where it produces xylem inwards which is towards pith, secondary phloem outwards, and towards the bark.
Vascular cambium is the main cambium, and it is also called bifacial cambium.
Vascular cambium is generally found in dicots and gymnosperms.
In general, the cambium is present between the xylem and the phloem is called intravascular cambium whereas, during the secondary growth, cells of the medullary rays are formed between the adjacent vascular bundle, which becomes meristematic and form interfascicular.
These meristematic cells divide tangentially in a parallel plane, to the surface of the stem.
As the cell division occurs where the secondary xylem and the phloem forms which moves the primary xylem and the phloem apart.
Mainly the cambium consists of 2 types of cells, they are fusiform initials and ray initials.
Fusiform initial cells are tall, and they are oriented axially. Whereas ray initials were smaller and round triangular.
So the correct option is B. Tangential.

Note: Vascular cambium is maintained by the signals coming from both the hormones and short cambial cells receive those signals from outside the meristem and act that regulate the internal factors, which promotes the proliferation of cells and differentiation.
