Question

The placenta is attached to the developing seed near the

(a) testa (b) hilum (c) micropyle (d) chalaza

Answer 1

(b) the placenta is attached to the developing seed near hilum. It is the scar located near the edge where seed breaks from stalk of funiculus, i.e., connecting the seed with fruit wall and placenta.

Rest of the options are incorrect as

Testa is the outer most covering of seed, micropyle is a small opening in seed coat through which water enters seed and chalaza is a tissue where nucellus and integument are joined. Nutrients from the plant travel through vascular tissue in the funiculus and outer integuments through the chalaza into the nucellus.
