- Structure that lets substances in and out of the cell. It encloses the cell.
- cell membrane
- part of the cell that controls the activities of the cell
- nucleus
- Process of cell when the cell divides into two
- mitosis
- process of substance moving from an area of greater concentration to an area of lesser concentration
- diffusion
- What are the 3 main points of the Cell Theory?
-
1. Cells are the basic units of structure.
2. All life processes are carried out by cells.
3. New cells are produced from existing cells. - The cell process used to make food from light energy is called
- photosynthesis
- The process to maintain the balance of water inside and outside of a cell is
- osmosis
- is found only in plant cells. It is stiff and gives a rigid (firm) shape to the cell.
- Cell wall
- TRUE / FALSE: Human cells only need to do photosynthesis during the winter.
- FALSE
- nuclear membrane
- allows substances to move in and out of the nucleus
- cell membrane
- holds the cell together and allows substances to pass in and out of the cell
- chromosomes
- Structures inside the nucleus that are made up of genes.
- How many times is an object magnified at 4X?
- 40 times magnification
- How many times is an object magnified at 10X?
- 100 times magnification
- The difference between a plant cell and an animal cell--
- Animal cells do not do photosynthesis.
- What process maintains the balance of water inside and outside of a cell?
- osmosis
- The specialization of cells is called
- cell differentiation
