Answer 2

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

(1) Multicellular organisms with walled and frequently vacuolate eukaryotic cells.

(2) They contain photosynthetic pigment in plastids.

(3) Principle mode of nutrition is photosynthesis but number of plants has become absorptive.

(4) Primarily non-motile, living anchored to a substrate.

(5) Structural differentiation leading towards organs of photosynthesis, anchorage and support and in higher forms towards specialized photosynthetic, vascular and covering tissues.

(6) Reproduction is primarily asexual or sexual. The reproductive organs are multicellular.


(7) A multicellular embryo is formed during development from the zygote. Algae lack embryo stage. Life cycle consists of alternating haploid gametophyte and diploid sporophyte generation. This phenomenon is called alternation of generation.
