| I. | The major lipids are phospholipids |
| II. | Peripheral proteins are only partially buried in the membrane |
| III. | Lateral movement of lipids in protein bilayer is measured as its fluidity |
| 1. | Only I is correct |
| 2. | Only III is correct |
| 3. | Only II and III are correct |
| 4. | Only I and III are correct |
| 1. | the outermost layer is the cell wall |
| 2. | all three layers act together as a single protective unit |
| 3. | the cell membrane staining properties make some bacteria Gram positive |
| 4. | carbohydrate is the biomolecule absent in all three layers |
| 1. | Mitochondria - produce cellular energy in the form of ATP |
| 2. | Golgi body - provides packaging material |
| 3. | Lysosomes - secrete hydrolytic enzymes |
| 4. | Endoplasmic reticulum - synthesis of lipids |
| 1. | a layer present between cell wall and membrane of bacteria |
| 2. | cell wall of bacteria |
| 3. | bacterial cell glyco-engineered to possess N-glycosylated proteins |
| 4. | a layer surrounding the cell wall of bacteria |
| 1. | All plants are composed of different kinds of cells which form the tissues of the plant. |
| 2. | Animal cells have a thin outer layer which is today known as ‘plasma membrane’. |
| 3. | Cells divide and new cells are formed from pre-existing cells. |
| 4. | The presence of cell wall is a unique character of the plant cells. |
| Statement I | Both the cilium and flagellum emerge from centriole-like structure called the centrosome. |
| Statement II | Centrosome is an organelle usually containing two cylindrical structures called centrioles. |
| 1. | Only I | 2. | Only II |
| 3. | Both I and II | 4. | Neither I nor II |
| Assertion (A): | Cell is the fundamental structural and functional unit of all living organisms. |
| Reason (R): | Anything less than a complete structure of a cell does not ensure independent living. |
