- If both assertion and reason are true and reason is the correct explanation of assertion
- If both the assertion and reason are true but reason is not the correct explanation of assertion
- If assertion is true but reason is false
- If both the assertion and reason are false
Hide Solution
Verified By Collegedunia
The Correct Option is B
Solution and Explanation
In a typical angiospermic plant, cotyledons in the seed are the embryonic leaves. The radicle of the embryo upon the seed germination produces the root system and the plumule produces the shoot system. The radicle and plumule are contained in the embryo.

Post-Fertilization Events
There are series of events that happen in the development of plants after their fertilization process to form a fruit from a diploid zygote. The four different developmental steps that occurs during post fertilization are:
- Development of an Endosperm: The endosperm, a tissue, present in the seed during the fertilization, precedes the development of an embryo. It is categorized into three types.
- Nuclear Formation
- Cellular Formation
- Helobial Formation
- Development of an Embryo: Embryogeny is the embryo development process and it starts developing at the micropylar end of the embryo sac in the zygote. The formation stages of embryogeny are almost the same in both the plants dicot and monocot, regardless of their structure.
- Monocot Embryo
- Dicot Embryo
- Development of a Seed: A Seed has Three Body Parts:
- Seed Coat
- Cotyledon
- Embryo Axis
- Formation of a Fruit: After the cell division and separation in the ovary, it is changed into fruit because of stimuli received from fertilization just as developing seed. The pericarp which might be fleshy like guava, tomato, or cucumber or might be weathered and dry like pea, bean, or mustard. After all the events the two types of fruits are formed:
- True Fruit
- False Fruit
