- Biology Unit 2
- Cells and cell structure
- palisade mesophyll thin, tightly packed
- yeast cell has nucleus, cytoplasm, membrane and wall
- bacterial cell has a cytoplasm, membrane, wall and genetic material
- Plants obtaining food and growth
- Respiration > converts glucose to other useful substances
- Cell wall > cellulose that strengthens walls
- Proteins > glucose + nitrate ions = amino acids to make proteins
- Seeds > glucose makes lipids stored in seeds
- Starch > stored in leaves, roots, stems (insoluble
- Ecology
- Reliability - large sample size
- Reproducible - random samples
- Validity - control variables, answering the question
- Mean = total/no. quadrats
- Proteins and functions
- structural components of tissues, muscles, hormones, antibodies, catalysts
- AMYLASE is in small intestine,pancreas and salivary gland
- PROTEASE is in small intestine,pancreas and stomach
- LIPASE is in small intestine,pancreas and stomach
- Energy from respiration
- glucose + oxygen = carbon dioxide + water
- glucose = lactic acid + energy
- increase in heart rate = increase rate of blood flow
- removal of carbon dioxide prevents oxygen debt
- Organisms changing through time
- gradual replacement, casts & impressions, preservation
- environmental changes,new species or predators, bad events, disease, competition
- natural selection - each population, alleles control the characteristics best to survive
- Patterns of inheritance
- meisosis:cell divides 2x to form 4 gametes (with single set of chromosomes)
- Each gene codes for a particular combinationof amino acids which make a specific protein
