The following cells cannot be grown under tissue culture conditions
1 HeLa cells
2 Leucocytes
3 Kidney cells
4 Nerve cells
Explanation:
D Tissue culture is a technique used in biology to grow the cells in in-vitro condition (outside of the body) by preparing a suitable culture media. Neurons are post-mitotic cells which means they are matured and do not further divide. HeLa name is taken from the patient Henrietta Lacks\(\mathrm{HeLa}\) cells are used to test whether a cell line in cancerous or not.

Main function of cerebellum is:
1 Balancing
2 Sight
3 Hearing
4 Memory
Explanation:
A The main function of cerebellum is balancing. The cerebellum is the part of brain located at the back of the brain, below the cerebrum. It is responsible for coordinating voluntary movements, maintaining balance and posture. Hearing, sighting and memory are all function of the cerebrum, which is the largest part of the brain.

Schwann cell is found around :
1 Axon
2 Cyton
3 Dendrite
4 Dendron
Explanation:
A Schwann cells are present on the axon of a neuron. They wrap around the axon and form a myelin sheath, which helps to insulate the axon and speed up the conduction of nerve impulses.
C Nervous tissues are derived from ectoderm. Germ layers | (i) Ectoderm | Outermost layer, form during embryonic development. It gives rise to nervous system, the skin and the hair. | | :--- | :--- | | (ii) Mesoderm | Middle layer, it gives rise to the bones, muscles and connective tissues. | | (iii) | The innermost layer, it gives rise to the lining of the digestive tract, the respiratory tract, and the urinary tract. |
