Endosperm is consumed by developing embryo in the seed of:
1 pea
2 maize
3 coconut
4 castor
Explanation:
In Pea and groundnut, endosperm is consumed by developing Embryo of the seed. The endosperms is completely absorbed by the growing embryo. Pisum sativum Such seeds are called non-endospermic exalbuminous.

The hilum is a scar on the :
1 Fruit, where it was attached to pedicel
2 Fruit, where style was present
3 Seed, where micropyle was present
4 Seed, where funicle was attached
Explanation:
The hilum is a scar on the seed, where the funicle was attached. In flowering plants, the ovule is found inside the portion of the flower called the gynoecium. The ovary of the Gynoecium produces one or more ovules and eventually change into the fruit wall. Ovules are attached to the placenta through a stalk called funicle. Ovule attaches to the funicle at the region called hilum. In the seed, hilum is present as a scar and represents the point of attachment of the seed to the fruit. ANATOMY OF A BEAN SEED

Which one of the following fruits is parthenocarpic?
1 Banana
2 Apple
3 Brinjal
4 Jackfruit
Explanation:
Exp. A Banana is a parthenocarpic fruit therefore seedless. Formation of fruit without fertilization is called parthenocarpy. Parthenocarpy occasionally occurs as a mutation in nature, it affects every flower, the plant can no longer sexually reproduce but might be able to propagate by apomixis or by vegetative means. Examples- this include many citrus variety that undergo unicellular embryony.

Winged pollen grains are present in
1 Mustard
2 Cycas
3 Pinus
4 Mango
Explanation:
Winged pollen grains are present in Pinus. It is extended outer exine on two lateral sides to form the wings of pollen. It is the characteristic feature, only in Pinus. - In Pinus, the pollination is anemophilus, the pollen grains suspend in the air for a long time due to wings. - Pollen grain appear as yellow dust and popularly known as sulphur shower. - The pollen grain of mango are spheroidal. - In mustard they are prolate to subspheroidal - In cycas pollen grains are top shaped.
