4. Lysosome
Non-membranous nucleoplasmic structures in the nucleus, are the sites for active synthesis of:
| 1. | protein | 2. | mRNA |
| 3. | rRNA | 4. | tRNA |

| (d) | Ribosomes | (iv) | Digesting biomolecules |
Choose the right match from the options given below:
| Options: | (a) | (b) | (c) | (d) |
| 1. | (iii) | (iv) | (ii) | (i) |
| 2. | (iv) | (iii) | (i) | (ii) |

Mark the incorrect statement
| 1. | All the cell organelles perform different & specific function. |
| 2. | Basal body of cilia & flagella in prokaryotes is formed by cytoskeleton. |
| 3. | Endoplasmic reticulum helps in transport. |
| 4. | Microbodies are present in both plants and animals. |
The organelles formed by the process of packaging in the golgi apparatus is
| 1. | Double membrane organelle. |
| 2. | Possess single circular DNA molecule |
| 3. | Rich in hydrolases |
| 4. | Able to occupy up to 90 percent volume of the cell |
Read the following statements carefully
| A. | Lipid component of the plasma membrane mainly consists of phosphoglycerides. |
| B. | Polar molecules can pass through the lipid bilayer of plasma membrane, therefore they do not require carrier proteins to facilitate their transport. |
| C. | Secondary wall is capable of growth and it is formed on the outer side of the cell |
| D. | Quasi fluid nature of lipid enables lateral movement of proteins within the overall lipid bilayer of plasma membrane |
| E. | Middle lamella glues the different neighbouring cells together |
