Question

The endosperm of an angiosperm differs from that of a gymnosperm in that it:

• A. Contains glycogen rather than starchcontains less fat
• B. Contains less fat
• C. Does not form until fertilization takes place
• D. Only lasts a few days

Answer 1

The correct option is C Does not form until fertilization takes place

In angiosperms, the endosperm is formed after fertilisation as a result of triple fusion. During the double fertilisation process in angiosperms, one sperm nuclei fuse with the egg cell forming the zygote and the other sperm nuclei fuse with the two polar nuclei, forming a triploid cell (3n). This triploid cell forms the endosperm. In gymnosperms, on the other hand, the endosperm is formed before fertilisation from the cells formed after the meiotic division of the megaspore mother cell that does not form the megaspore but undergoes degeneration.

So, the correct option is 'does not form until fertilization takes place'.
