  • Mitochondria produce energy through aerobic respiration.
  • Chromosomes are made up of genes that determine characteristics such as eye colour or height.
  • The nucleus is the control centre of the cell, containing DNA.
  • the cell wall is made of cellulose which stregnthens the wall
  • mitochondria release energy
  • the chloroplast contains chlorophyll
  • the vacuole contains sap and helps support the cell
  • the ribosomes are synthesis of protein
  • the cytoplasm is where chemical reactions take place
  • the magnification equation is image/actual
  • the photosynthesis equation is cabon dioxide + water--> glucose +oxygen
  • uses of glucose are storage of starch, storage of sucrose, storage of lipids, cellulose, protein and respiration
  • the limiting factors are light, carbon dioxide and temperature
  • diffusion is the spreading out of particles from a high concentration to a low concentration
  • osmosis is the movement of water molecules across a partially permeable membrane from a region of higher water concentration to a region of lower water concentration
  • active transport is the movement of particles against a concentration gradient from an area of low concentration to an area of high concentration
  • the phloem transports food ( mainly dissolved sugars)
  • the xylem transports water and minerals
