Question

Gymnosperms differ from pteridophytes inhaving -a)Presence of tracheiodsb)Presence of embryoc)Presence of ovuled)Companian cellCorrect answer is option 'C'. Can you explain this answer?

Answer

Pteridophytes are seed less spore bearing plants.Gymnosperms have seed without fruit .
The term 'gymnosperm' means plants with 'naked seeds' after the unenclosed condition of their seeds(called as ovules in their unfertilised state.

Answer

The term "gymnosperm" means plants with "naked seeds" after the unenclosed condition of their seeds called as ovules in their unfertilised state.

Answer

Difference Between Gymnosperms and Pteridophytes
Gymnosperms and pteridophytes are two distinct groups of plants, and one of the key differences lies in their reproductive structures. Let’s explore this further.
Key Characteristics of Gymnosperms
- Presence of Ovuled Structures:
- Gymnosperms produce seeds that are not enclosed within an ovary. Instead, their ovules are exposed on the surface of cone scales, which are part of the reproductive structures called cones.
- This is a significant evolutionary advancement over pteridophytes, which reproduce via spores and do not produce seeds.
Differences in Reproductive Strategies
- Seed Formation:
- The presence of seeds in gymnosperms allows for better protection and nourishment of the developing embryo compared to the spore-based reproduction of pteridophytes.
- Embryo Development:
- In gymnosperms, the embryo develops within the seed after fertilization, providing a means of survival during unfavorable conditions.
Comparison with Pteridophytes
- No Seed Formation:
- Pteridophytes, such as ferns, reproduce through spores and do not have the complex reproductive structures that gymnosperms possess.
- Lack of Ovuled Structures:
- Pteridophytes do not produce ovules or seeds, making them fundamentally different from gymnosperms.
Conclusion
In summary, the presence of ovules in gymnosperms is a defining characteristic that sets them apart from pteridophytes. This adaptation has allowed gymnosperms to thrive in various environments and has played a crucial role in their evolutionary success.
