CELLS

3. membrane-functions as a semi-permeable barrier, allowing a very few molecules across it while fencing the majority of organically produced chemicals inside the cell
5. refers to all of the cellular material inside the plasma membrane, other than the nucleus.
7. er a network of tubular membranes within the cytoplasm of the cell, occurring either with a smooth surface
8. cell is made up of microtubules, actin filaments, and intermediate filaments.
10. are structures in the cytoplasm where proteins are made.
12. apparatus- complex of vesicles and folded membranes within the cytoplasm of most eukaryotic cells, involved in secretion and intracellular transport

1. membrane-a microscopic membrane of lipids and proteins that forms the external boundary of the cytoplasm of a cell or encloses a vacuole, and that regulates the passage of molecules in and out of the cytoplasm.
2. are a part of tissue cells that consists of an outer and an inner membrane
4. single membrane organelles that are essentially part of the outside that is located within the cell
6. Bilayer-is a thin polar membrane made of two layers of lipid molecules
9. is the digestive system in the cell. It breaks down molecules into their base components digestive enzymes
11. er a network of tubular membranes within the cytoplasm of the cell
