Question

In Angiosperms arrange the events of pre-fertilization/post-fertilization in a sequence:

• A. Sporogenesis — Spores/Gametogenesis — Gametes
• B. Gametes — Syngamy/Embryo — Endosperm
• C. Gametogenesis — Gametes transfer/Zygote — Embryo
• D. Spores — Gametes/Zygote — Embryo

Hint:

In fertilization, remember the sequence:

• Gametogenesis forms gametes.
• Gametes fuse during fertilization.
• Zygote forms and develops into an embryo.

Answer 1

The Correct Option is C

To solve the problem, we need to arrange the events of pre-fertilization and post-fertilization in the correct sequence for Angiosperms.

1. Understanding the Events:
In Angiosperms, the sequence of events begins with the formation of spores and ends with the embryo formation. Let's break down the sequence of events involved:

2. Analyzing the Correct Order:
The correct sequence of events should follow these steps:

• Spore Formation: Spores are produced during the process of sporogenesis.
• Gamete Formation: The spores develop into gametes through gametogenesis.
• Fertilization: The gametes fuse together during syngamy to form the zygote.
• Embryo Formation: The zygote develops into the embryo.
• Endosperm Formation: After fertilization, the endosperm is formed to nourish the developing embryo.

3. Correct Sequence:
The correct sequence of events is:

Spore formation (sporogenesis) → Gametes formation (gametogenesis) → Gametes transfer (syngamy) → Zygote formation → Embryo formation

4. Choosing the Correct Option:
The correct option that matches this sequence is:

Final Answer:
The correct answer is (C) Gametogenesis → Gametes transfer → Zygote → Embryo.

Answer 2

The correct sequence is (3).
Gametogenesis leads to the formation of gametes (male and female).
Gametes transfer occurs during fertilization, leading to the formation of a zygote.
The zygote develops into an embryo.
