Cells

Cards (15)

  • All living things are made of cells
  • Ribosomes make proteins
  • The nucleus contains genetic material (DNA) which controls the activities of the cell
  • Vacuoles store water and other substances within plant cells
  • Chloroplasts contain chlorophyll, which is used to capture light energy during photosynthesis
  • Cell membranes control what enters or leaves the cell
  • Cytoplasm is a gel-like substance where most of the chemical reactions occur. It contains enzymes that control these chemical reactions.
  • Eukaryotes are organisms that are made up of eukaryotic cells
  • A prokaryote is a single-celled organism that does not have a nucleus.
  • Prokaryotes include bacteria and archaea
  • Plants have a rigid cell wall - made of cellulose. It supports the cell and strengthens it
  • A permanent vacuole contains cell sap - a weak solution of sugar and salts
  • Bacterial cells don't have a 'true' nucleus - instead they have a single circular strand of DNA that floats freely in the cytoplasm
  • Bacterial cells may also contain one or more small rings of DNA called plasmids
  • Bacteria don't have chloroplasts or mitochondria by they have a cell wall and a cell membrane
