| Question | Answer |
|---|---|
| the organelle that determines all of a cell's activities and the production of new cells | nucleus |
| this type of cell allows an animal to move | muscle |
| the part of a cell that stores food, water or waste products | vacuole |
| these types of cells have cell walls or chloroplasts | plant |
| this describes the feature of a cell membrane that allows substances to pass through it | permeable |
| this type of cell protects an animal from the environment | skin |
| different cells in an animal serving different functions is called this | specialization |
| a jellylike substance that contains many chemicals to keep the cell functioning | cytoplasm |
| an instrument that can be used to magnify an animal cell so that you can see it | microscope |
| the process by which a cell can make new copies of itself and is how cells can reproduce | cell division |
| Smallest unit of living things. The basic unit of living things and they can grow, reproduce and die | cell |
| the covering that holds the plant or animal cell together and separates it from its surroundings | cell membrane |
| all living things are made up of these | cells |
| this produces energy for the cell | mitochondria |
| threadlike structures that contain information about the characteristics of the plant | chromosomes |
| this controls what enters and exits the nucleus | nuclear membrane |
| working parts of a complete cell each each have their own function in the life process of a cell | organelles |
| a rigid layer that supports and protects the plant cell | cell wall |
| organelles that make food for the plant cell | chloroplasts |
| particles of a substance move from an area where there are a lot of particles to an area with less | diffusion |
| movement of water and dissolved materials through cell membranes | osmosis |
| cells that work together to perform a specific function | tissue |
| tissues work together to form this | organ |
| organs that work together to perform a function form this | system |
