Resource summary

Module B4: The Processes of Life
1 Cell Structure and Function
1.1 Plant Cells and animal cells
1.1.1 Similarities Nucleus; contains DNA (instructions for making proteins) Cytoplasm; gel-like substance where proteins (e.g. enzymes) are made Anaerobic respiration happens here Cell membrane: holds cell together, controls what goes in and out, gases and water pass through freely, barrier to other chemicals Mitochondria: where the enzymes needed for aerobic respiration are, where reactions take place.
1.1.2 Differences Plant cells have a cell wall, supports the cell, strengthens it. Plant cells have a vacuole in the centre, weak solution of sugar and salts Plant cells, have chloroplasts, where photosynthesis takes place, contain chlorophylland enzymes for photosynthesis
1.2 Yeast are single celled microorganisms
1.2.1 used to make bread and wine
1.2.2 they have: cytoplasm, a cell membrane, a nucleus, mitochondria and a cell wall.
1.3 Bacteria have simple cell structures
1.3.1 no nucleus, circular DNA in cytoplasm
1.3.2 no mitochondria but can respire anaerobically
1.3.3 has a cell membrane, a cell wall, cytoplasm and a circular DNA molecule
2 Enzymes
