KÏÑGDØM PLÅÑTÅË (PLÅÑT KÏÑGDØM)



Plants are eukaryotic chlorophyll-

containing

organisms

with

cellulosic cell wall. (NEET 2018)



Some are partial heterotrophs

(e.g.

insectivorous

plants

like

bladderwort & Venus flytrap) or

parasites (e.g. Cuscuta).



Plantae

includes

algae,

bryophytes,

pteridophytes,

gymnosperms and angiosperms.



Life cycle of plants has 2 phases:

Diploid sporophytic & haploid

gametophytic. These phases alternate with each other. This is called

alternation of generation.



Among different plant groups, length of the haploid & diploid phases is

varied. Also, these phases are free living or dependent on other.

KÏÑGDØM ÅÑÏMÅLÏÅ (ÅÑÏMÅL KÏÑGDØM)

Animals are

multicellular,

heterotrophic,

eukaryotic

organisms without

cell wall.

They have a definite

growth pattern and

grow into adults

that have a definite

shape and size.

They directly or

indirectly depend on

plants for food.

Higher forms

show sensory

and neuromotor

mechanism.

They digest their

food in an internal

cavity and store food

reserves as glycogen

or fat. Their mode of

nutrition is holozoic

(by ingestion of food).

Most of them

are capable of

locomotion.
