Updated On: Apr 14, 2024
- A - Cotyledon, B - Coleoptile, C - Scutellum, D - Epithelium
- A - Endosperm, B - Coleoptile, C - Scutellum, D - Epithelium
- A - Endosperm, B - Coleorrhiza, C - Scutellum. D - Epithelium
- A - Endosperm, B - Coleoptile, C - Scutellum, D - Aleurone layer
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
Scutellum is the single cotyledon and aleurone layer is the protein separation layer of embryo and endosperm in monocot seed.

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
