KINGDOM PLANTAE

Members of Plant Kingdom are multicellular, eukaryotic, photosynthetic organisms.

Main characters of the members of this kingdom are:

Cellulosic cell wall.

Non-motile, excepts some aquatic forms.

Presence of chloroplasts.

Photosynthetic mode of nutrition (oxygenic photosynthesis), e.g., different types of algae (green, brown, red algae), bryophytes, pteridophytes, gymnosperms and angiosperms.

Growth is usually indefinite.

Some of the plants are heterotrophic. They are mostly parasitic. A few are saprobes.

small group of autotrophic plants catch small animals and insects for obtaining nitrogen.They are called carnivorous or insectivorous plants.

Reproduction is both asexual and sexual. Accessory spores are present in lower plants.

An embryo stage is absent in the algal group but present in others.
