Question:
The endosperm of gymnosperm is
The endosperm of gymnosperm is
Show Hint
The endosperm of gymnosperms is a pre-fertilization tissue that is equivalent to the female gametophyte.
Updated On: Jul 15, 2024
- diploid
- polyploid
- triploid
- haploid.
Hide Solution
Verified By Collegedunia
The Correct Option is D
Solution and Explanation
The endosperm of gymnosperms is haploid. It is a pre-fertilization tissue that is equivalent to female gametophyte, therefore it is haploid in nature. However, in angiosperms, it is the post-fertilization tissue and is triploid in nature.
Therefore, the correct option is D) Haploid.

- Given below are two statements: Statement I: In the RNA world, RNA is considered the first genetic material evolved to carry out essential life processes. RNA acts as a genetic material and also as a catalyst for some important biochemical reactions in living systems. Being reactive, RNA is unstable.
Statement II: DNA evolved from RNA and is a more stable genetic material. Its double helical strands being complementary, resist changes by evolving repair mechanisms. In the light of the above statements, choose the most appropriate answer from the options given below:- NEET (UG) - 2025

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
