Eggs do not occur in archegonia in:-

Options

A. Bryophyta
B. Pteridophyta
C. Angiosperms
D. Spermatophyta

Answer

**Step-by-Step Solution:**

1. **Understanding Archegonia**: Archegonia are multicellular structures found in the gametophyte phase of certain plants. They are responsible for producing and containing the female gamete, known as the ovum or egg.

2. **Structure of Archegonia**: Archegonia typically consist of two main parts: a long neck canal and a swollen base called the venter. The neck canal can be either above the surface or embedded within the plant tissue.

3. **Presence of Archegonia in Different Plant Groups**: Archegonia are commonly found in non-flowering plants such as bryophytes (mosses) and pteridophytes (ferns). In these plants, the egg is enclosed within the archegonia.

4. **Archegonia in Angiosperms**: In angiosperms (flowering plants), archegonia are absent. Instead, the female gametophyte is reduced to a few cells, and the egg cell is contained within an ovule, which is enclosed by the carpel (megasporophyll).

5. **Conclusion**: Since archegonia are absent in angiosperms, the correct answer to the question "Eggs do not occur in archegonia in:" is angiosperms.

**Final Answer**: Angiosperms (option 3).
