Cells

• The nucleus contains genetic material that controls the activities of the cell.
• Red blood cells and bacteria cells do not contain a nucleus.
• A plant cell contains a large, singular vacuole that is used for storage of water, salts, minerals, nutrients and proteins and maintaining the shape of the cell. Animal cells do not have this.
• Prokaryotic cells lack a nucleus and other organelles. They are divided into two distinct groups: the bacteria and the archaea. They are generally small, single-celled organisms that have a relatively simple structure.
• Cells of animals, plants and fungi are called eukaryotic cells . They contain membrane bound organelles such as a nucleus and mitochondria.
• Mitochondria are the site of aerobic respiration.
• Cytoplasm contains enzymes that carry out chemical reactions and is where most of the chemical reactions take place
• Cell membrane holds cell together and controls what goes in and out of the cell
• Mitochondria - where most of reactions for aerobic respiration take place, this respiration transfers energy that the cells need to work
• Ribosomes: where proteins are made
• Plant cells have a rigid cell wall made of cellulose
• Plant cells have a permanent vacuole
• Chloroplasts: where photosynthesis occurs, contain chlorophyll which absorbs the light needed for photosynthesis
• Bacteria don't have chloroplasts or mitochondria
• Bacteria are prokaryotes
