Resumo de Recurso
B4a - It's a green world.
Who Lives Where?
Zonation - A gradual change in the population density.
Abiotic Factors - pH, water or light availability can cause zonation.
no. of animals caught first x no of animals caught 2nd / no. of animals caught & marked 2nd time
Biodiversity - no. of organisms types in a habitat are how many of them there are
Transect line - a line you take samples along
Photosynthesis
6 Co2 + 6 H2O ----> C6 H12 06 + 6O2
Photosynthesis is a 2 step process. 1) Water --> Hydrogen Ions and Oxygen 2) Hydrogen ions + Carbon Dioxide --> Glucose
Glucose + Nitrogen ---> Protein
Glocose + Magnesium --> Chlorophyll
Rate Liminiting Factors = Light , Carbon Dioxide concentration & temperature
Plants need light & chlorophyll to photosynthesise.
Structure of a Leaf
Epidermis and cuticle are transparent to allow light--> pallisade
Chloroplasts close to top of leaf for efficient photosynthesis
Irregular mesophyll shaped cells = large surface area to volume rati for good diffusion of co2 from stoma to palisade
Range of photosynthesising pigments to absorb more wave lengths of light
Chloroplasts down sides of palisade cells so that some light can reach the mesophyll
Diffusion and Osmosis
Diffusion is net movement of particles from an area of high concentration --> low concentration. Increased by bigger surfaced area & smaller distance.
oxygen in leaf---> diffuses out thru stomata
Molecules diffuse until a equilibrium is reached
Passive Processes.
Osmosis is the net movement of high concentration of water --> low cencentration of water across a partially permeable membrane
partially permeable membrane = has holes in it so that water molecules can pass thru. too small for any other molecules
Plasmosis = cell membrane comes away from cell wall
