In the world of plants, there are some that are very simple. They do not have roots, stems, leaves, or any distinct parts. Examples include algae and fungi.
1
Moving on to a more complex category, we have plants with clear parts like roots, stems, and leaves. These plants are multicellular and more evolved than the simple ones.
2
Bryophytes are tiny plants like mosses. They lack true roots and water-conducting tissues. They are often found in moist areas without proper roots.
3
Pteridophytes have roots and conducting tissues but do not produce flowers or seeds. They are more complex than bryophytes but do not have flowers or seeds.
Spermaphytes are advanced plants that produce flowers and seeds. They are divided into three groups based on their seed covering: gymnosperms, chlamydosperms, and angiosperms.
6
Gymnosperms have seeds that are not enclosed in a fruit. The seeds are visible and not protected inside a fruit like in other plants.
7
Chlamydosperms have seeds that are partially covered by a simple sheath. The covering is not as complex as the fruits we are familiar with.
8
Angiosperms are plants with flowers, and their seeds are enclosed within a fruit. These are the plants we are most familiar with, like fruit trees.
