BiologyPhotosynthesisA2/A-levelOCR Created by: HollyhaCreated on: 04-05-16 20:22 What is the equation of photosynthesis? carbon dioxide + water = glucose + oxygen. 1 of 7 What is an heterotroph? Organisms that ingest and digest complex organic molecules releasing chemical potential energy stored in them. 2 of 7 What is an autotroph? Organisms that synthesise their own organic molecules (Carbohydrates, Proteins) using light energy, chemical energy and inorganic molecules. 3 of 7 What is a photoautotroph? Organisms that photosynthesise light energy, carbon dioxide and water e.g. plants, some bacteria. 4 of 7 What is a chemoautotroph? Organisms that use energy from exergonic chemical reactions. 5 of 7 Why is photosynthesis needed? Creates oxygen needed for respiration, takes carbon dioxide from the air and allows plants to grow and supports food chain. 6 of 7 What is the endosymbiont theory? When 2 organisms have a mutalistic relationship (both benefit) 1 organism lives inside another organism. 7 of 7
