CELLS

1. Is made up of Cytosol and Organelles
5. These have ribosomes attached at the outer surface of the membrane. It is involved in the intracellular transport of proteins.
8. The double membrane organelle that houses our DNA
9. It is selectively permeable, Provides a barrier around the cell separating its internal components from the extracellular enironment
11. These membranous sacs store food and water for a cell and are also used for waste disposal
14. A passive transport system within a cell that does not require energy
15. What type of diffusion only involves water?
17. The digestive system of a cell. They digest or break down worn-out organelles and foreign substances that enter the cell
19. The fluid inside a cell, excluding organelles
20. Which type of transport does not require energy (ATP) for the movement of substances across a cell membrane from an area of high concentration to an area of low concentration,
21. Involved in the process of making proteins
22. Active transport may take place with the help of these

2. Groups of cells combine to form these
3. Are located within the nucleus and produce ribosomes
4. A basic structural and functional unit of a body, and the smallest living unit
6. This cell organelle helps process and package lipid proteins and molecules, esp. proteins for export through transport vesicles
7. Powerhouse of a cell and are responsible for generating most of the cell’s energy in the form of ATP
10. Proteins are often exported out of a cell in secretory vesicles. What is this type of transport called?
12. The tiny structures that carry out functions that float within the cytoplasm
13. What type of cell would contain a high proportion of mitochondria?
16. What is the primary energy carrier in cells and transported to other organelles within the cell(abbreviated)?
18. During this transport mode, energy is moving against their concentration gradient
