comparison between plant cell and animal cell:ribosomes

Study the structures of a typical animal cell and a typical plant cell as seen under an electron microsco..

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..

Cellulose cell wall surrounds the cell membrane.Cell wall is absent in animal cells..

Introduction - Every organism, whether its body is unicellular or multicellular, is capable of performing all vital functions such as respiration, ingestion, excretion and reproduction. In multicellular organisms, because of the increase in body size, it is difficult for each cell to effi..

Differences Between Plants and Animals - Plants Animals Cellulose cell wall surrounds the cell membrane Cell wall is absent in animal cells Plastids are present especially a green pigment called chlorophyll Ch..

Cell Theory - Two German biologists M.J.Schleiden (1838) and Theodore Schwann (1839) proposed the cell theory (or cell doctrine), which unified the ideas prevailing at that period on the organisation in plants and animals. The cell theory ..

Characters Parenchyma Collenchyma Sclerenchyma Definition Simple, living storage tissue. Simple, living, mechanical tissue. Simple, dead mechanical tissue. Shape of the cells Spherical or oval, sometimes rectangular or irregular. Elongated, polygonal or spherical..

Excretion in Plants - In plants, breakdown of substances is much slower than in animals. Hence accumulation of waste is much slower and there are no special organs of excretion. Green plants in darkness or plants that do not contain chlorophyll prod..
