Ovules are naked in gymnosperm because:-

Options

A. Fertilisation is absent
B. True carpels are absent
C. Archegonia are absent
D. Endosperm is absent

Answer

**Step-by-Step Solution:**

1. **Understanding Gymnosperms**: Gymnosperms are a group of seed-producing plants that do not form flowers or fruits. The term "gymnosperm" means "naked seeds," which indicates that their seeds are not enclosed within an ovary.

2. **Naked Ovules**: In gymnosperms, the ovules are referred to as "naked" because they are not enclosed by any protective structure like an ovary. This is in contrast to angiosperms (flowering plants) where ovules are enclosed within a fruit.

3. **Absence of True Carpels**: Gymnosperms do not possess true carpels, which are the structures that typically enclose ovules in flowering plants. The absence of these structures means that the ovules remain exposed.

4. **Seed Formation**: Despite the absence of flowers and true carpels, gymnosperms still produce seeds. The seeds develop on the surfaces of modified leaves or cones, which is a characteristic feature of gymnosperms.

5. **Conclusion**: Therefore, the reason ovules are naked in gymnosperms is due to the absence of true carpels that would normally enclose them. This leads to the formation of naked seeds.

**Final Answer**: Ovules are naked in gymnosperms because they do not have true carpels that enclose them.
