Question

What are phanerogams?
A) Plants with well differentiated reproductive tissues
B) Plants that makes seeds
C) They bear cones
D) Both A and B

Answer 1

Hint: Phanerogams include advanced plants such as gymnosperms and angiosperms.

Complete Answer:
Let us know a little about phanerogams before finding the correct answer. Phanerogams are plants which have well differentiated reproductive tissues. They have seeds which enclose embryos and stored food.

Option A: Phanerogams are plants containing well differentiated reproductive tissues. Therefore, this is the correct option.

Option B: Phanerogams can make seeds. Therefore, this is the correct option.

Option Phanerogams cannot bear cones. Therefore, this is the incorrect option.

Option D: Phanerogams are plants bearing seeds and are known as spermatophytes. The plant body of phanerogams are well-differentiated into three distinct parts – roots, stem, and leaves. They possess a well developed vascular system.
They have two categories of plants groups under them,
1) Angiosperms - Example- Wheat
2) Gymnosperms - Example- Pine

In angiosperms, the seed is found enclosed in the seed coat whereas in gymnosperms the seeds are present without a seed coat and are present inside modified cones. They have modified reproductive structures too.
1) Angiosperms- Carpels and ovules
2) Gymnosperms- Strobilus

Therefore, as both A and B are correct, this is the correct option. (Though A and B are correct, option D is the most suitable option.)

Thus, the correct option D) both A and B.

Note: These are the most advanced versions of the plants bearing seeds. The primitive group of plants include,
Thallophyta - It includes algae- Ulothrix, chara, etc
Bryophyta - It includes Funaria, Marchantia
Pteridophyta - It includes Ferns, horse-tails, etc
