PLANT CELLS
Across
- 3. It occupies around 30% of the cell’s volume in a mature plant cell.
- 4. They are the double-membraned organelles found in the cytoplasm of all eukaryotic cells.
- 6. They are found in non-photosynthetic tissues of plants. They are used for the storage of protein, lipid and starch.
- 7. They are found in all eukaryotic cells which are involved in distributing synthesized macromolecules.
- 8. It is an elongated organelle enclosed by phospholipid membrane. The chloroplast is shaped like a disc.
- 14. It is the semi-permeable membrane that is present within the cell wall. It is composed of a thin layer of protein and fat.
- 15. Are the transport cells in vascular plants. They help in the transport of water and minerals from the roots to the leaves and other parts of the plants.
- 16. They are hard or rigid cells, which play a primary role in providing support to the plants when there is restraining growth in a plant due to lack of hardening agent in primary walls.
- 18. The vital function of a nucleus is to store DNA or hereditary information required for cell division, metabolism and growth.
- 19. They are the smallest membrane-bound organelles which comprise RNA and protein.
- 20. Is the gel-like fluid inside the cell. It is the medium for chemical reaction. It provides a platform upon which other organelles can operate within the cell.
Down
- 1. Referred to as the “traffic police” of the cell. They play a key role in sorting many of the cell's proteins and membrane constituents, and in directing them to their proper destinations.
- 2. Needle-shaped crystals of calcium oxalate monohydrate or calcium carbonate as aragonite.
- 5. They are the living cells of plants, which are involved in the production of leaves.
- 9. Is the most conspicuous domain in the eukaryotic cell nucleus, whose main function is ribosomal RNA (rRNA) synthesis and ribosome biogenesis.
- 10. They are necessary to store starch, to carry out the process of photosynthesis.
- 11. Is a group of crystals of calcium oxalate, silicates, or carbonates present in plants, and are thought to be a defense against herbivory due to their toxicity.
- 12. Are plastids or organelles responsible for the storage of starch granules.
- 13. It is a rigid layer which is composed of cellulose, glycoproteins, lignin, pectin and hemicellulose.
- 17. Are called suicidal bags as they hold digestive enzymes in an enclosed membrane.
