vairity of living organisms
all living things follow MRSGREN
M-MOVEMENT-the action of muscles in animals or the slow groth of plants
R-RESPIRATION- get energy from food
S-SCENSITIVITY-scence the change in the souroundings
G-GROWTH- increace in sze and massusing materials for food
R-REPRODUCTION-producing more off spring
E-EXCREATION-the removal of toxic waste
N-NUTRITION- taking in and using food
cell structures
tipical plant and animal cell
ANIMAL CELL HAS ;
- cell membrane
- cytoplasm
- nucleus
- (can include michondria)
PLANT CELL HAS ;
- cell wall
- cell membrane
- chloroplast
- nucleus
- vacual
- michondria
THE FUNCTIONS
Cytoplasm-where the activitys happen+jelly like substanceA
Nucleus-controls the cell+contains DNA AP
Cell membrane-allows cells to pass through and out AP
Mitchondria-where aerobic respiration takes place+relese energy AP
Cell wall-holds the cell together P
Vacual-storage space for cell sap,dissolved sugars, minrals and irons P
Chloroplast-makes photosynsisist P
Ribosome- site of photosynsist P
THE 5 IVING KINGDOMS OF LIFE AND FACTS
ANIMAL;
- example-mammels and incects
- multicellular
- has a nervouse system
- can change shape as has no cell wall
- does not contain chloroplats
- PLANT;
- example-flowering plant, cereals
- multicellular
- contains chloroplast for photosynsist
- cell wall made from cellulouse
FUNGI
- example-yeast
- multicellular or unicellular
- do not contain chloroplast
- cmade from hyphe
- reproduse using spores which are carried in the air
- have many nucli
BACTERIA
- examples-lactobactillus (made in yeast)
- unicellular
- have no nuclus
- contains plasmids (EXTRA DNA)
- smallest kingdom
PROTOTICS
- example-amoebea
- multicellular or unicellular
- doesnt fit into any other kingdom
- cells like animal called protozea
- cells like plank called allgea
- some have chloroplat others do not
MICROORGANISMS
-Out of the microorganisms the smalest is virus, (second)- bacteria (last)- fungi
FUNGI
- made from thread like fragments called hyphe
- multicellular amd contain many nucli
- they feed saprotropically -
SAPROTIC FEEDING-put enzyms on food-,absorb back into hyphe
BACTERIA
- no nucleus DNA is free
- contains plasmids (extra loops of DNA)
- some have tail for swimming (FALLUGUM)
- cells are bigger than some kingdoms
VIRUS
- Smallest type of organism
- only follow 1/6 of MRSGEN
- reproduce in other cells
- they have a protien coat
- they may have DNA
ORGANISATION WITHIN PLANTS AND ANIMALS
STAGE 1=ORGANELLE-things that make uo the cell ; vacual, cytoplasm,nucleus
STAGE 2=CELL-…
