Across
- 4. A green pigment that captures light energy for photosynthesis
- 6. in eukaryotic cells, the organelle that is the site of cellular respiration which releases energy for use of the cell.
- 7. the process in which cells use energy to produce food
- 8. A molecule that is made up of amino acids and that is needed to build and repair body structures and regulate the process of the body
- 11. The process by which a cell membrane surrounds a particle and encloses the particle in a vesicle to bring the particle into the cell
- 12. a cell organelle composed of RNA and protein; the site of protein synthesis
- 15. a living thing; anything that can carry out life processes independently
- 16. the movement of substances across the cell membrane that requires the cell to use energy
- 17. Complex- a cell organelle that helps make and package materials to be transported out of the cell.
- 18. a rigid structure that surrounds the cell membrane and provides support to the cell
- 19. a cell organelle that contains digestive enzymes
Down
- 1. Acid- A molecule made up of subunits called nucleotides
- 2. in eukaryotic cells. A process of cell division that two new nuclei, each of which the same number of chromosomes
- 3. an organelle found in plant algae cells where photosynthesis occurs.
- 5. the movement of substances across a cell membrane without use of energy by the cell
- 9. the process by which a cell releases a particle by enclosing the particle in a vesicle that then moves to a cell surface and fuses with the cell membrane
- 10. a fluid filled vesicle found in the cytoplasm of plant cells or protozoans.
- 13. the diffusion of water through a semipermeable membrane
- 14. the process by which cells use oxygen to produce energy from food
