Cell | Basic unit of living things |
Cells | Animal and Plant |
Cell organelles | All parts of the cells |
Animal Cell | Nucleus, Cell membrane, Cytoplasm, Ribosome, Mitochondrion |
Plant cell | Nucleus, Cell membrane, Cytoplasm, Ribosome, Mitochondrion, Cell Wall, Vacuole and Chloroplast |
Nucleus | Brain of the cell, controls activities (chromosomes containing DNA) |
Cell membrane | Controls substances in and out of the cell |
Cytoplasm | Watery fluid the cell organelles are in |
Ribosomes | Proteins are made here |
Mitochondrion | Powerhouse of the cell. Supplies energy to the cell, involved in respiration |
Cell wall | Gives structure and support to the plant cell. Protects cell |
Vacuole | Stores substances such as water and food |
Chloroplasts | Contain a green pigment called chlorophyll that is used to make food for the plant through photosynthesis |
Photosynthesis | Using sunlight to make food for plant |
Groups of living things | Bacteria, Fungi, Plants, Animals and Others (Protists) |
Microscope | Viewing microscopic organisms |
Types of microscopes | Light and electron |
Eyepiece | For viewing the slide, makes the object x10 times bigger |
Focus knobs | To see object more clearly |
Objective lens | Different magnifications |
Nosepiece | Can rotate to select different objective lens |
Stage | Used to support microscope slide |
Clips | Holds slide in place |
