Across
- 2. -where genetic material is stored and controls the cell's growth and reproduction
- 4. – cells with a nucleus
- 6. - rigid structure that surrounds the cell membrane in plant cells; provide structure and support.
- 8. – gel-like liquid inside a cell; helps cell maintain shape and is about 80% water.
- 10. - describes the basic characteristics of all cells and organisms
- 12. – a fluid-filled vesicle that contains food, water and waste. Plant cells have a large central vacuole that stores water.
- 13. the smallest functional and structural unit of all living things
- 15. – deoxyribonucleic acid, a molecules that is present in all living cells and that contains information that determines traits.
- 17. –structures within a cell that have special functions to keep the cell working.
Down
- 1. – an organelle found in plant and algae cells where photosynthesis occurs.
- 3. – cells without a defined nucleus; usually smaller than eukaryotic cells
- 5. (mitochondrion) – the site of cellular respiration, which releases energy for use by the cell.
- 7. – the arrangement of parts in an organism
- 9. – one of the structures in the nucleus that are made up of DNA and protein
- 11. - protective, flexible barrier that controls what goes in and out of the cell.
- 14. – the special, normal or proper activity of an organ or part.
- 16. – a system of ideas that explains many related observations and is supported by a body of evidence acquired by scientific investigation.
