Levels of Organisation
1) Cells Contains ORGANELLES
Eukaryotic or Prokaryotic
Eukaryotic are complex cells
Plant and Animal cells
Prokaryotic cells are small and simple
Bacteria Cell
Organelles are tiny structures in the cell
Animal Cell
Nucleus (genetic material)
Cell Membrane (controls what goes in and out)
Cytoplasm (chemical reactions, enzymes)
Mitochondria (aerobic respiration)
Ribosomes (proteins are made)
Plant Cell
Chloroplasts (photosynthesis, contains chlorophyll)
Cell Wall (supports, rigid structure, made of cellulose)
Vacuole (cell sap, support cell)
2) Similar Cells are organised into TISSUES
Tissues work together
Carry out a particular function
Can contain more than 1 cell type
Xylem tissue
water and mineral salts
Phloem tissue
sucrose and amino acids
3) Tissues are Organised into ORGANS
Different tissues working together
Lungs and Leaves are examples of Organs
4) Organs make up ORGAN SYSTEMS
Organs work together
Do different jobs
Digestive System
Made up of the stomach, intestines, pancreas and the liver
