Plants make their own food by photosynthesis. Carbon dioxide and water react together in the presence of light and chlorophyll to make glucose and oxygen. The glucose is converted into starch, fats and oils for storage. It is used to make cellulose for cell walls, and proteins for growth and repair. It is also used by the plant...
Animal Cell Structure Animal cells are typical of the eukaryotic cell, enclosed by a plasma membrane and containing a membrane-bound nucleus and organelles. Unlike the eukaryotic cells of plants and fungi, animal cells do not have a cell wall. This feature was lost in the distant past by the single-celled organisms that gave rise to the kingdom Animalia. Most...

Generally, plant cells are larger than animal cells and are mostly similar in size and are rectangular or cube shaped. Plant cells are similar to animal cells in being eukaryotic and they have similar cell organelles. What is a Plant Cell? Plant cells are eukaryotic cells i.e.,...
