Question

explain briefly the kingdom plantae​

Answer 1

Answer:

Explanation:

Kingdom Plantae

Kingdom Plantae includes green, brown and red algae, liverworts, mosses, ferns and seed plants with or without flowers. They have the following characteristics:

They are multicellular organisms with walled and frequently vacuolate eukaryotic cells.

These contain photosynthetic pigment in plastids. The principle mode of nutrition is photosynthesis.

They are primarily non-motile and live anchored to a substrate.

Reproduction is primarily asexual or sexual. The reproductive organs are multicellular. They form a multicellular embryo during development from the zygote. Algae lack the embryo stage.

The life cycle consists of alternating haploid gametophyte and diploid sporophyte generation. This phenomenon is called the alternation of

Answer 2

ANSWER:-

Plantae is the plant kingdom which contains all plants on the earth. They are multicellular eukaryotes. Characteristically, they contain a rigid structure that surrounds the cell membrane known as the cell wall. Plants also have a green colored pigment known as chlorophyll that is quite vital for photosynthesis.

Characteristics of Kindom Plantae:-

The plant kingdom has the following characteristic features:

• They are non-motile.

• They follow the autotrophic mode of nutrition.

• These are multicellular eukaryotes with cell wall and vacuoles.

• These contain photosynthetic pigments called chlorophyll in the plastids.

• They ave different organelles for anchorage, reproduction, support and photosynthesis.

Considering all these factors, the plant kingdom has been classified into five subgroups. They are as follows:

1. Thallophyta              
2. Bryophyta
3. Pteridophyta
4. Gymnosperms
5. Angiosperms
