Across
- 2. body, a flattened, layered, sac-like organelle that finishes processing the proteins made by the ribosomes and “packages” them to transport to where they are needed in the cell
- 3. gene that is expressed in an individual when paired with a recessive gene in inheritance
- 5. an organelle within the nucleus
- 9. a green pigment, present in all green plants, responsible for the absorption of light to provide energy for photosynthesis
- 11. the process by which green plants use sunlight to synthesise nutrients from carbon dioxide and water
- 13. physical or observable features of an organism
- 15. the gene that is masked or not expressed in the presence of a dominant gene
- 16. where proteins are created that the cell needs
- 18. each of two forms of a gene that are found together on a chromosome
- 19. fluid-filled, membrane-surrounded cavities inside a cell. It fills with food being digested and waste material that is on its way out of the cell and also breaks down old and damaged parts of the cell and also store chemicals that the cell needs
Down
- 1. the fluid of the cell that all the cell’s organelles are contained within
- 2. genetic information for a trait
- 4. the smallest structural and functional unit of an organism
- 6. only in plant cells, these organelles convert solar energy to chemical energy that the cell can use
- 7. spherical to rod-shaped organelles - the energy centre of the cell. Converts food energy into chemical energy the cell can use
- 8. round organelles surrounded by a membrane and containing digestive enzymes. Digests the cell’s food and wastes
- 10. the study of heredity and the variation of inherited characteristics
- 12. thin layer of protein and fat that surrounds the cell
- 14. the control centre of the cell. It controls many of the chemical reactions that occur within the cytoplasm.
- 17. a self-replicating material which is present in nearly all living organisms as the main constituent of chromosomes, and the carrier of genetic information
