Solution
The correct option is C Callose
- Callose is a plant polysaccharide formed in various part of the plants.
- It plays an important role in the differentiation of pores in the phloem, in microsporogenesis, functioning of stomata closure cells and protection of plant cells from biotic and abiotic stresses.
- During microsporogenesis, callose is deposited in walls of mother cells of microspores at the beginning of prophase.
- Each microspore wall thus contains a thick callose layer at the stage of formation of microspore tetrads.
- When the microspores are released from tetrads the lysis of callose layer occur.
- So, the correct answer is 'Callose'.
