  • 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
