Q.
Identify the structures marked $A$ to $F$ in the given diagram
A) A-Asymmetric nucleus, B-Nucleus, C-Generative cell, D-Vegetative cell, E-Pollen, F-Pollen tetrad
B) A- Pollen tetrad , B- Pollen, C-Generative cell, D-Vegetative cell, E-Asymmetric spindle, F-Nucleus
C) A-Pollen tetrad, B-Vacuole, C-Nucleus, D-Asymmetric spindle, E-Vegetative cell, F-Generative cell
D) A-Vacuole, B-Nucleus, C-Pollen tetrad, D-Vegetative cell, E-Asymmetric spindle, F- Generative cell
Explanation
Stage of microsporogenesis forming pollens. Pollen Grain When pollen grain matures it contains two cells (i) Vegetative cell Vegetative cell is bigger and has abundant food reserve and a large irregular shaped nucleus (ii) Generative cell The generative cell is small and floats in the cytoplasm of vegetative cell. It is spindle-shaped with dense cytoplasm and a nucleus [image:2_image48.png]
