Cereals during germination derive their food from
1 Soil
2 Starch
3 Embryo
4 Aleurone grains
Explanation:
Cereals during germination derive their food from aleurone grains. It is a layer of protein. This aleurone layer is located between the endosperm and the seed coat. Aleurlone grains are small, protein rich structures found in the outermost layer of cereal grains like wheat, barley and oats. They are particularly abundant in wheat. Aleurone cells contain enzymes that play a crucial role in the germination of the grain, breaking down stored nutrients into forms that can be used by developing plant embryo.

Which of the following floral parts forms pericarp after fertilization?
1 Nucellus
2 Ovary wall
3 Outer integument
4 Inner integument
Explanation:
Exp. C After fertilization in flowering plants the pericarp, which is the outer layer of the fruit, undergoes changes ovary wall. But some fruits the pericarp may remain relatively unchanged. Some fruits, the pericarp may be thicken and harden to protect the developing seed. Some fruits the pericarp may fleshy and succulents to attract animals that help disperse the seeds like cherries and tomato. After fertilization, the ovary wall it often develops into the fruit's outer layers, including the pericarp.

When pollen tube enters through micropyle, the process is called
1 porogamy
2 chalazogamy
3 mesogamy
4 apogamy
Explanation:
The pollen tube may enter the ovule by following one of three routes given below : Porogamy - Pollen tube enters the through microphyle, eg, most angiosperm. Mesogamy - Pollen tube enters the ovule through integuments or through functions. Chalazogamy-Pollen tube enters the ovule through chalazal tissues, eg. Casuarina, Beta vulgairs, Juglens regia etc.

The coconut water and the edible part of coconut are equivalent to:
1 Mesocarp
2 Embryo
3 Endosperm
4 Endocarp
Explanation:
The coconut water is the free nuclear endosperm while the surrounding white kernel is cellular endosperm. It has a membranous epicarp, fibrous mesocarp and stony endocarp. The endocarp encloses a single seed with brown testa that contain a small embryo and a white oily endosperm (edible part) with watery fluid called coconut water. Endosperm formed due to triple fusion and is triploid in nature. Its development starts shortly before the development of the embryo it is formed by three method nuclear type cellular type and Helobial type.
