2. Red blood cell(RBC) in human blood is a single cell.
3. A tissue is a group of cells performing a specific function.
4. Dyes (like safranin) are used to colour parts of the cell to study their details.
5. The plastid responsible for the green color of leaves is the chloroplast.
6. Genes control the transfer of a hereditary characteristic from parents to offspring.
7. Prokaryotic cells have nuclear material without a nuclear membrane.
8. The cells, like onion cells and cheek cells, are examples of eukaryotic cells.
9. An organ is a structure that contains more than one type of tissue.
10. The porous membrane that allows the movement of materials between the cytoplasm and the inside of the nucleus is the nuclear membrane.
11. Basic structural units of living organisms are cells.
12. Protoplasm which is between the nucleus and plasma membrane is cytoplasm.
13. Nucleus and mitochondria are cell organelles in a human cell.

Answer 2:

The parts of the nucleus are as follows:

1. Nuclear membrane
2. Nucleoplasm
3. Chromatin fibers
4. Nucleolus
5. Endosomes

Answer 3:

1. Nucleus: It is often referred to as the brain of the cell and is responsible for coordinating all types of activities/reactions taking place inside the cell.
2. Plastids: These are double-membrane bound organelles found exclusively in plant cells and responsible for the storage of chloroplast and photosynthesis.
3. Genes: These are the functional and structural units of heredity and is responsible for the transfer of genetic information from parent to progeny.
4. Cell membrane: It is a type of semipermeable membrane that allows the entry and exit of chemicals/molecules needed by the cell for various reactions.
5. Pseudopodia: The term pseudopodia mean false feet, it is a membranous extension used for the capture of food.
