biology

• 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
