Question

Unlike flowering plants and conifers, the primitive vascular plants do not produce ______.

a. seeds
b. fruits
c. flowers
d. spores

Answer 1

The correct option is a. seed. Primitive vascular plants, like lycophytes and pterophytes, do not produce seeds but instead rely on spores for reproduction.

Step-by-step explanation:

Unlike flowering plants (angiosperms) and conifers (gymnosperms), primitive vascular plants do not produce seeds. Instead, these plants, including lycophytes and pterophytes, reproduce through spores. This is a characteristic of seedless vascular plants, such as ferns, club mosses, and horsetails.

Gymnosperms like redwoods, cypresses, and firs, do have seeds but they do not have flowers. On the other hand, flowering plants have both seeds and flowers, with the seeds often enclosed within fruits. Therefore, the correct answer is (a) seeds.
