Cell structures

• Eukarytoic cells are complex and include all animal and plant cells
• Prokaryotic cells are smaller and simpler e.g. bacteria
• Eukaryotes are organisms that are made up of eukaryotic cells
• A prokaryote is a prokaryotic cell (it's a single celled organism)
• Animal cell structures: Nucleus, Cytoplasm, Cell membrane, Mitochondria and Ribosomes
• Nucleus - contains genetic material and controls the activities of the cell
• Cytoplasm - gel like substance where most of the chemical reactions happen, it contains enzymes to control these reactions
• Cell membrane - holds the cell together and controls what goes in and out
• Mitochondria - where reactions for aerobic respiration take place
• Ribosomes - where proteins are made in the cell
• Respiration tranfers energy that the cell needs to work
• Plant cell structures: Rigid cell wall, permenant vacuole and chloroplasts
• Cell wall - made of cellulose, supports and strengthens the cell.
• Permenant vacuole - contains cell sap, a weak solutions of sugar and salts
• Chloroplasts - where photosynthesis occurs, they contain chlorophyll which traps the light needed for photosynthesis
• Bacterial cells are prokaryotes
• Bacterial cell structures: Cytoplasm, cell membrane, cell wall, a singular strand of DNA and plasmids
