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-
