What is Kingdom Plantae in Biology
Kingdom Plantae in Biology
Kingdom Plantae
Introduction
Includes all eukaryotic multicellular and chlorophyllous living organisms, which have cell wall made up oftrue cellulose.
Majority of members are autotrophic but few are parasite e.g.: “Cuscuta”
They have localized growth, regions of growth lying primarily at the extremities that is root and stem apioes.
Classification of Kingdom Plantae
Kingdom planatae is divided into tow sub-kingdom on the basis of presence or absence of vascular tissue (xylem and phloem).
A – Sub-Division – Bryophytes (Non- Vascular)
1- Class Hepatica (Liverworts)
2- Class Musci (Mosses)
3- Class Anthroccrota (Homworts)
B- Sub-Division – Tracheophytes
1- Class Psilopslda (Psllopsids)
2- Class Lycopsida (Club Mosses)
3- Class Sphenopsida (Horse Tails)
4- Class Pteropsida (Ferns)
5- ClassSpermopsida (Seed Plants)
Sub -Division Bryophyta (Amphibian Plants) Or (Non-Vascular Plants)
1- Absence of lignin-fortilied tissue to support tall plants on land.
2- Members of this sub-division usually sprawl horizontally as mats over a large surface.
3- Always have a low profile (1 -2om-2ocm tall).
4- Regular heteromorphic alternation of generation is present w/t gametophytes dominancy (Gametophytes large and long lived).
what did you learn from what you read in a week, what you heard, what you remember – and the frightening answer will become clear – nothing. People endlessly repeat other people’s ideas, words and thoughts without adding anything of their own, or, at best, retell them in their own words. News occasions, reactions to them, comments on the reaction, angry refutation of comments on the reactionaries … and it is very difficult to resist this myself, and I want to comment on another loud news, repost a funny picture, make another selection of other people’s photos …
