AQA GCSE Biology - CELLS-Questions with Correct Answers|Verified
Tissue - ✔✔A group of cells working together to perform a function E.g. Skin, muscle, liver,
brain
Cell - ✔✔The building blocks of all living organisms. Cells can be prokaryotic or eukaryotic
Eukaryote - ✔✔Plant and Animal cells are eukaryotic cells as they have a cell membrane,
cytoplasm and a nucleus
Prokaryote - ✔✔Bacterial cells are prokaryotic cells as they are very very small have a cell
wall around their cell membrane and they do not have a nucleus
Cell Membrane - ✔✔An envelope that surrounds the cell and lets substances in and out
Nucleus - ✔✔Contains DNA and controls the cells activity
Cytoplasm - ✔✔The jelly centre of the cell which holds the sub-cellular structures and is
where all the chemical reactions happen
Cell Wall - ✔✔Only found in plant cells and bacterial cells. In plant cells the cell wall is made
of cellulose
Single DNA Loop - ✔✔In prokaryotic cells (bacteria) the DNA is found as a single loop
Plasmid - ✔✔A small ring of DNA found in prokaryotic cells (bacteria)
Mitochondria - ✔✔This is where respiration happens in cells which gives the cells energy
Chloroplasts - ✔✔Only found in plant cells, these contain chlorophyll and are the sites of
photosynthesis and are green
