Question

4. Using the illustrations above, arrange the following statements FROM 1-5 to explain the process of pollen formation in angiosperms.

A.	The generative cell subsequently detaches from the pollen grain wall and is engulfed by the vegetative cell forming a unique 'cell within a cell' structure.
B.	Each microspore will form large vacuole displacing the microspore nucleus to an eccentric position against the microspore wall.
C.	The nucleus undergoes first pollen mitosis which results in the formation of two unequal cells, a large vegetative cell and a small generative cell each containing a haploid nucleus.
D.	The generative cell divides by mitosis to form two sperm cells completely enclosed within the vegetative cell cytoplasm.
E.	No cytokinesis takes place forming a pollen grain having 3 haploid nucleus, 1 tube nucleus and 2 sperm cells for double fertilization.
