Biology

2. an intercellular structure made of both RNA and protein, and it is the site of protein synthesis in the cell.
4. the structure in a cell that contains the chromosomes.
6. the gelatinous liquid that fills the inside of a cell
7. a structure that helps cells maintain their shape and internal organization
10. a membrane-bound cell organelle that contains digestive enzymes.
11. an organism whose cells contain a nucleus within a membrane
12. the spreading of something more widely.
13. The cell wall is the outer covering of a cell, present adjacent to the cell membrane, which is also called the plasma membrane
14. any external solution that has the same solute concentration and water concentration compared to body fluids.
15. a small cavity or space in tissue, especially in nervous tissue as the result of disease.
17. the spontaneous passage or diffusion of water or other solvents through a semipermeable membrane
18. generate most of the chemical energy needed to power the cell's biochemical reactions
20. a minute cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division.

1. a large, dynamic structure that serves many roles in the cell including calcium storage, protein synthesis and lipid metabolism
3. ion pumps, exocytosis and endocytosis.
5. organisms whose cells lack a nucleus and other organelles
8. produce energy through photosynthesis and oxygen-release processes, which sustain plant growth and crop yield
9. a self-regulating process by which a living organism can maintain internal stability while adjusting to changing external conditions
16. transport, sorting and modification of both protein and lipid
19. the semipermeable membrane surrounding the cytoplasm of a cell.
