Question

Inter fascicular cambium:
A.Is same as fascicular cambium
B.Are cylindrical meristems
C.Cannot produce secondary tissues
D.Are actually cork cambium

Answer 1

Hint: Cambium is part of a plant that exists in the form strips composed of meristematic cells between the primary xylem and primary phloem, especially in dicot plants. The main function of the cambium is the production of vascular tissues, called vascular cambium. These tissues produce an arrangement of secondary xylem towards the inner side and secondary phloem on the outer side in parts of plants like stems and roots.

Complete answer:
Option A- Is same as fascicular cambium
Fascicular cambium exists between the xylem and phloem within a vascular bundle also called fascicles. It is also known as intrafascicular cambium due to their presence inside the fascicles.

Option B- Are cylindrical meristems
The cambium appears cylindrical due to the arrangement of cells of the cambium vertically (fusiform cells) and horizontally (ray cells).

Option C- Cannot produce secondary tissues
Interfascicular cambium is a secondary meristem. It is present in secondary parts of the plants and can produce secondary tissues.

Option D- Are actually cork cambium
Cork cambium is a lateral meristem which is present between the cork and primary phloem. It is responsible for secondary growth in plants.

Hence the correct answer is OPTION(B)

Note: Vascular cambium is also known as the main cambium, wood cambium or bifacial cambium. The tissues in the cambium promote the growth of the plants in stems and roots. It doesn’t help in the transport of water or food through the plant. In mature parts of the plants, the interfascicular and intrafascicular cambium can’t be differentiated.
