Explain plantae Kingdom
Answers
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. 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 embryo stage.
Life cycle consists of alternating haploid gametophyte and diploid sporophyte generation. This phenomenon is called alternation of generation.
Plant kingdom has two categories
Undifferentiated. --- DIVISION THALOPHYTA
Differentiated body----- DIVISION BRYOPHYTA. ( amphibian of plant king Dom) eg. Mosses
DIVISION PHTERIDOPHYTA EG. FERNS
DIVISION. GYMNOSPERMS. (DO NOT PRODUCE SEEDS)
DIVISION. ANGIOSPERM S. ( PRODUCE SEED WITH OUTER COVERING)
ANGIO SPERMS ARE DIVIDED INTO TWO
DICOTS AN D MONOCOT PLANTS
