Question

What are the features of seed-bearing plants?

Answer 1

Hint: Seed plants have special structures on them (flowers or cones) where special male and female cells join through a process called fertilisation. After fertilisation, a tiny plant called an embryo is formed inside a seed. The seed protects the embryo and stores food for it. The seed is dispersed away from the parent plant, and when conditions are right, the embryo germinates and grows into a new plant.

Complete answer:
Seed-producing plants have the following characteristics:
1. Plants that produce seeds are classified as spermatophytes.
2. Gymnosperms and angiosperms are two types of seed-producing plants.
3. Megasporangium must be retained in seed-producing plants.
4. Plants that reproduce by generating seeds include Cycas, Pinus, and Cocos.

Compared to most terrestrial plants, ancestral plants were aquatic photosynthetic organisms with a much lower size. Through a succession of evolutionary breakthroughs, ancient plants gradually evolved into species capable of living on dry land. Liverworts, mosses, and hornworts are the simplest terrestrial plants, with stomata, a waxy cuticle, and specific reproductive systems. These characteristics allowed plants to grow to great heights on dry land without drying out. Ferns are descendants of the first plants with roots, stalks, and leaves. The clades of land plants with the most members are the gymnosperms and angiosperms. Angiosperms have flowers, which distinguishes them from other clades. The seed was a significant evolutionary breakthrough because it allowed plants to reproduce on land without the use of water.

Note:-
It's a seed-producing plant. The seed-bearing plants are made up of gymnosperms and angiosperms. Because of the evolution of seeds and pollen, seed-bearing plants have been a hugely successful group in the history of life. Plants have two unique phases in their life cycle: sporophytic (sporophytic) and gametophytic (gametophytic), which alternate.
