Outer most living limit of a plant cell is Cell wall Plasma membrane Cytoplasm Tonoplast 2. Which model explains selective permeability of plasma membrane ? Sandwichmodel Fluid mosaic model Trilamellar model Unit membrane model 3. ER extends from Middle lamellum to plasma membrane Tonoplast to plasma membrane Nuclear envelope to plasma membrane Primary wall to secondary wall 4. Universal cell organelles (found in all living cells) are Ribosomes Plastids Mitochondria Vacuoles 5. “These are regarded as “”protein factories””” Golgi complex Ribosomes Nucleoli Microsomes 6. Cell organelles which can be seen only with electron microscope are Plastids Mitochondria Endoplasmic reticulum Ribosomes 7. Lipochondria and Idiosomes are the alternative names of this cell organelle Mitochondria Lysosomes Golgi complex Elaioplasts 8. Chtokinesis is inhibited if the following becomes non functional Phragmoplast Ribosomes Lysosomes Dictyosomes 9. Which of the following is described as cell within the cell or prokaryotic cell within a eukaryotic cell? Nucleus Ribosome Mitochondria Endoplasmic Reticulum 10. In Mitochondria, electron transport occurs in the Cristae Matrix Ribosome All the above 11. More mitochondria would be found in Meristematic cells Epidermis Companion cells Xylem parenchyma 12. Repository of cell is Mitochondria Chloroplast Lysosome Vacuole 13. The pigment found in vacuole that imparts blue, red or violet colours is Carotene Anthocyanin Xanthophyll Phycobilins 14. Suicidal bags of a cell were discovered by DeDuve Fontana Palade Golgi 15. Digestion of foreign particles within the cell by lysosomes is called Autolysis Autophagy Phagocytosis Heterophagy 16. What is untrue about lysosomes? Polymorphic organelle Bring about autolysis Carry out intracellular digestion Formation of cell plate 17. The cell organelle that reduces the number of other cell organelles is Mitochondrion Elaioplast Lysosome Golgi complex 18. “Nucleus is often described as “”cell brain”” because “ It is located in the centre of the cell It is shaped like that of brain It controls and coordinates various metabolic activities It can divide and give rise to new nuclei Loading … Related posts: Cell The Unit of Life Test No-6 Cell The Unit of Life Test No-7 Cell The Unit of Life Test No-8 Cell The Unit of Life Test No-15 Cell The Unit of Life Test No-16 Powered by YARPP.
