Anaerobic respiration is the type of cell respiration that takes place in the absence of oxygen. This types of respiration occurs in yeast cells and our muscle cells after a strenuous exercise.

Lenticels are the lens-shaped small pores on the surface of the stems of woody plants. Lenticels consist of thin walled loosely arranged cells with intercellular spaces for gaseous exchange.

3. Cellular respiration occurs partially in the cytoplasm and in:

a. Mitochondria

b. Nucleus

c. Golgi bodies

d. Ribosomes

Answer - Nucleus

Nucleus is the largest organelle present in the eukaryotic cells. In mammalian cells, the size of the nucleus typically varies from 11 to 22 µm in diameter. It is spherical in shape.
