Question | Answer |
---|---|
What are organisms | Organisms are living things |
what are the characteristics of life | Movement Growth Reproduction Nutrition Sensitivity Excretion Respiration Composed of cells |
What is a cell? | A cell is the smallest working unit of a living organism |
Parts of an Animal Cell and their Function | Ribosome: makes protein Cell Membrane: semi-permeable membrane that allows some substances through e.g. water but not others e.g. protein Nucleus: controls the working of a cell Cytoplasm: watery fluid that holds the cell organelles |
Parts of an Animal Cell and their Function part 2 | Mitochondria powerhouse of cell |
Parts of an Plant Cell and their Function | Vacuole: stores food and water Cell wall: support and protection Chloroplast: place where photosynthesis occurs ribosome: makes protein Mitochondria: powerhouse of cell Nucleus:controls the working of a cell |
Parts of an Plant Cell and their Function | Cytoplasm: watery fluid that holds the cell organelles Cell Membrane: semi-permeable membrane that allows some substances through e.g. water but not others e.g. protein |
Differences between a Plant Cell and an Animal Cell | Plant Cell: Cell wall, has vacuole, has chloroplasts, is rectangular Animal Cell: no cell wall, has no chloroplast, does not have a vacuole, is round |
parts of the microscope | Eyepiece: to see/look into Arm Stage: holds the cell in place Coarse focus knob: brings image roughly into focus Fine focus knob: brings image precisely into focus Objective lenses: magnifies image light: So we can see cell |
