Give us energy and tissue repair
Absorbed and assimilated
Autotrophs ( Plants + Algae)
Heterotrophs (Animals)
Saprotroph (Bacteria + Fungi)
Needed for 'species' to survive
A group of organisms capable and producing fertile offspring
Asexual reproduction - Gametes not used
Sexual reproduction - Joining gametes
Grow as number of its cells increase
Glucose + Oxygen = CO2 + H2O (+ Energy)
Animals move to obtain food or find mates - Plants can also move (Mimusa Pudica)
Internal movements of Organelles and fluids, and external movement (Locomotion)
Some animals are sessile, or move very little
Living things response to changes in the enviorment
e.g. Plant grow toward light
Composed of cells
Levels of organization
Adaptation to enviorment (Evolution)
Maintain homeostasis (pH,Temp., salinity)
Bionomial Nomenclature

Genus - Capitalized, underlined or Italicized
Species - Lower case, underlined or italicized
Taxonomic categories
Kingdom
Phylum
Class
Order
Familiy
Genus
Species
Monera (Bacteria), Protista (single cells organism), Plantae, Fungi, Animalia
Biology 2 - Cells
Living organisms are made up of cells
Animal cells
Cell membrane that surround nucleus and cytoplasm
Nucleus contains chormosomes
Red Blood Cell - Biconcave, no nucleus, Haemoglobin
Plant cell
Vacuole, filled with cell sap - Cellulose - Starch grains storage - Chloroplast
Osmosis - Diffusion in water, plants take in water by osmosis
Water Potential Gradient
When WPG is lower in the cell than the surrounding, it can absorb water
WPG in cells are higher in leaves than roots
1665, Robert Hooke observed bark cells using simple microscope
1675, Anton van Leeuwenhoek first observed living cell, RBC
Cells are usually 10-100um.
1mm = 1000um
Biology 3 - Enzymes
Proteins that are biological catalysts
Too much heat can denature, and too little heat will make it slower to act
Extreme pH will denature the enzymes
Denature - Change of active site so it can no longer take in the substrate
