Question

Why do the mature seeds of plants such as peas possess no endosperm?
[1 mark]

• A. These plants are not angiosperms
• B. Double fertilisation does not take place in these plants
• C. Lack of tissue producing endosperm
• D. Endosperm gets used up by the developing embryo

Answer 1

The correct option is D Endosperm gets used up by the developing embryo

Pea plant is an angiosperm as it has flowers and produce seeds enclosed within a fruit.

Double fertilisation takes place in pea plants. In this method one sperm nucleus fuses with the egg nucleus to form an embryo and another fuses with polar nuclei to form the endosperm.

However, the endosperm formed as a result of double fertilisation is used up by the developing embryo. This is why the mature seed of plants such as peas do not have endosperms in them. Hence option d is correct.

Double Fertilisation
