fill in the blanks

1. complete the following table by filling in the correct cell part or function.

cell part	function
nucleus	directs cell activities.
endoplasmic reticulum	folds proteins into various shapes or adds other molecules to them.
mitochondria	manufactures substances important for cell functions. releases energy in the cell.

longer answer

1. list three premises of the cell theory.
2. all living things are made up of one or more cells and their products.
3. the cell is the simplest unit that can carry out all life processes.
4. all cells come from other cells; they do not come from non - living matter.
5. which organelles does a plant cell have that an animal cell lacks?

Explanation:

1. d; 2. a; 3. f; 4. g; 5. b. Mitochondria release energy. Chromatin contains genetic info. Chloroplasts for photosynthesis. Vacuole stores. Golgi body modifies, packages. Lysosomes digest. Plant - cell - unique: cell wall, chloroplasts, large vacuole.

Answer:

1. d
2. a
3. f
4. g
5. b
6. Mitochondria: Releases energy in the cell. Chromatin: Contains genetic information. Chloroplast: Site of photosynthesis. Vacuole: Stores water, food, and waste products. Golgi body: Modifies, packages, and distributes proteins and lipids. Lysosome: Digests wastes.
7. All living things are made of cells. The cell is the basic unit of life. All cells come from pre - existing cells.
8. Cell wall, chloroplasts, large central vacuole.
