Question

Distinguish gymnosperm and angiosperm.

Answer 1

Hint: Both gymnosperm and angiosperm are vascular plants having a life cycle of sporophyte -dominant one. Angiosperms have variegated colors and shapes of leaves, flowers, and fruits because of many varieties of the fruits and flower-bearing plants. Whereas gymnosperms are anatomically simpler because they do not bear flowers or fruits but the cones are present.

Complete answer:

Gymnosperms	Angiosperms
These are flowerless plants in which cones and seeds were produced. They bear seeds that were naked or unenclosed.	These are flowering plants which bear seeds in fruits or mature ovaries. The seeds are enclosed within an ovary.
These are evergreen plants of softwood type.	2. These are seasonal plants of hardwood type.
Leaves are needle-like or scale-like in shape.	3. Leaves are flat in shape.
4. Reproduction mostly relies on winds.	Reproduction mostly relies on pollinators.
The reproductive system is present in cones and is unisexual.	5. The reproductive system is present in flowers. They can be unisexual or bisexual.
Cone is a female reproductive organ whereas pollen is the male reproductive organ.	6. Flower carries both male reproductive organs (stamen) and female reproductive organs (pistil).
These plants are used in the making of various medicines, food, clothing, etc.	7. These plants are used in the making of paper, lumber, etc.
Example- cypress, gnetum, pine, spruce, redwood, ginkgo, cycads, juniper, fir, and welwitschia.	8. Example- roses, lilies, Broccoli, kale, Petunias, Eggplant, Tomato, Peppers, and sugarcane.
Gymnosperms have haploid tissue.	9. Angiosperms have triploid tissue.

Note:
1. The gymnosperms have originated in the late Carboniferous period, replacing the lycopsid rainforests of the tropical region. Whereas the angiosperms have originated in the late Cretaceous period, which is about 125 million years ago.
2. Today 1000 species of gymnosperms are known whereas 300000 species of angiosperms are known.
