Animal Cell Plant Cell Usually smaller in size. Usually larger in size. Cell wall absent. Cellulose in any form is absent. Cell wall made up of cellulose is present. Cytoplasm is denser, more granular and occupies most of the space in the ..
Somatic embryogenesis
In this method embryos are generated artificially by somatic cells carrying 2n chromosomes as against embryos normally produced in nature by gametes carrying chromosomes. These embryos are called embryoids . They are grown in large number in a small volume of nutrien..

. They show a (9+o) arrangement of microtubules. They are involved in the formation of spindle fibres during cell division and the basal bodies of cilia and flagella. Cilia and flagella are found in the surface of motile cells. They show a (9+2) arrangement of microtub..
The cells present in the matrix are of four types:
Fibrocytes are stellate or star shaped cells, which produce the matrix and white and yellow fibres. Macrophages are irregular, amoeboid cells which can ingest bacteria and other disease producing germs by phagocytosis. Mast cells are spherical or oval cell..
