Cell Structure

Cell Parts Part Function Found in
Page 1 2 3 4 5 Cell Parts Part Function Found in Controls what substances can get into and out of the cell. Plant and animal cells Jelly-like substance, where chemical reactions happen. In plant cells there's a thin lining, whereas in animal cells most of the cell is cytoplasm. Controls what happens inside the cell. Carries genetic information. Where photosynthesis happens – chloroplasts contain a green substance called chlorophyll. Plant cells only Contains a liquid called cell sap, which keeps the cell firm. Made of a tough substance called cellulose, which supports the cell.

Cell Parts Part Function Found in Cell membrane
Page 1 2 3 4 5 Cell Parts Part Function Found in Cell membrane Controls what substances can get into and out of the cell. Plant and animal cells Cytoplasm Jelly-like substance, where chemical reactions happen. In plant cells there's a thin lining, whereas in animal cells most of the cell is cytoplasm. Nucleus Controls what happens inside the cell. Carries genetic information. Chloroplast Where photosynthesis happens – chloroplasts contain a green substance called chlorophyll. Plant cells only Vacuole Contains a liquid called cell sap, which keeps the cell firm. Cell wall Made of a tough substance called cellulose, which supports the cell.

Types of Animal Cells Large surface area, for oxygen to pass through
Contains haemoglobin, which joins with oxygen Long Connections at each end Can carry electrical signals red blood cell Long tail for swimming Head for getting into the female cell nerve cell sperm cell
7
Types of Plant Cells Hollow tubes to transport water
Large surface area to absorb water root hair cell Lots of chloroplasts to absorb light for photosynthesis xylem pallisade cell
