Parts+of+a+cell

Hello,I am Natalie.This pg is about parts of a cell. Animal cells have cell membranes,nucleus and cytoplasms.

The **cell** is the basic structural and functional unit of all known living organisms. It is the smallest unit of life that is classified as a living thing, and is often called the building block of life. Organisms can be classified as unicellular (consisting of a single cell; including most bacteria) or multicellular (including plants and animals). Humans contain about 10 trillion (1013) cells. Most plant and animal cells are between 1 and 100 µm and therefore are visible only under the microscope. The cell was discovered by Robert Hooke in 1665. In 1835, before the final cell theory was developed, Jan Evengalista Purkene observed small "granules" while looking at the plant tissue through a microscope. The cell theory, first developed in 1839 by Matthias Jakob Schleiden and Theodor Schwann, states that all organisms are composed of one or more cells, that all cells come from preexisting cells, that vital functions of an organism occur within cells, and that all cells contain the hereditary information necessary for regulating cell functions and for transmitting information to the next generation of cells.

animal cell: Do not bother about the mitochondrion. this is the most not chim diagram I found. If you want something more illustrative, here you go

Plant cell

Hi i am Tasha i found out some info on cells. Though Euglena is a type of micro-organism, it has chloroplast and can make its own food.Do u know that some plant cells do not have a cell wall!

===Hi all!I found a website on the similarities and differences of the animal cell and plant cell and is in a chart which might be much more clearer and easier to. It has also some short 4-5 paragraphs and there are some things like the cilia, ribosomes etc. stuff which are more for upper level so read the ones like nucleus, cytoplasm etc in the chart. The picture is a little too complicated for our level so I looked for a picture which labels out the similarities and differences of the animal and plant cell. Hope it works!=== []
