Across
- 4. the materials or protoplasm within a living cell excluding the nucleus
- 5. a colored plactid other than a chloroplast, contains a yellow or orange pigment
- 6. pours and holes in lower epidermis, allows exchange of gases plant and atmosphere
- 9. has many ribosomes attached, synthesize proteins
- 10. upper and lower, one cell layer thick, let light pass through to mesophyll layer
- 12. the control center of a cell
- 13. pipe like structure, sometimes aggregating to form more complex structures
- 14. cylindrical organelle near the nucleus in animal cells, in pairs and involve development of spindle fibres in cell division
- 15. protein packaging organelle
- 16. thread like structure, present in numbers in the eukaryotic cells
- 18. a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid
Down
- 1. a rigid layer of polysaccharides lying outside the plasma membrane of the cells of plants, fungi and bacteria
- 2. a colorless orgranelle found in plant cells, used for storage of starch oil
- 3. organelles that specialize in photosynthesis, contain green pigment chlorphyll found in plant cells
- 6. free of ribosomes and is the area in which fats and lipids are synthesized
- 7. outer most edge of a cell, only found in animal cells
- 8. organelles that specialize in aerobic respiration
- 11. organelle in the cytoplasm of eukaryotic cells containing degradative enzymes enclosed in membrane
- 15. occur in pairs on lower epidermis, open and close stomata
- 17. organelles in which proteins are synthesized
