Animal Cell Electron Microscope
A microscope is an instrument that magnifies objects otherwise too small to be seen, producing an image in which the object appears larger. Most photographs of cells are taken using a microscope, and these pictures can also be called micrographs. From the definition above, it might sound like a microscope is just a kind of magnifying glass.
TEM of Plant Cell
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.

It is responsible for controlling the cell. 2.3.3 Identify structures from 2.3.1 in electron micrographs of liver cells. Figure 2.3.2 - Electron micrograph of an animal cell 2.3.4 Compare prokaryotic and eukaryotic cells. Prokaryotic cells have naked DNA which is found in the cytoplasm in a region named the nucleoid.

Animal cell. Transmission electron micrograph of a mammalian tissue culture cell. Taking up most of the cell is the nucleus, where genes are stored in the form of chromosomes. The dark zone (centre right) in the nucleus is the nucleolus. This is the most active part of the nucleus, and contains unravelled chromosomes involved in making protein.

Electron Micrograph Of A Plant Cell
In an electron micrograph of leaf cells from a quiescent desiccated dessert plant, Selaginella lepidophylla,. In animal cells they participate in spindle fiber formation during mitosis and are the point from which microtubules radiate thorough the cell to help form and maintain its shape. These structures do not involve axonemes.

The only structures found in animal cells but not plant cells are the centrioles and microvilli. Plant cells also have additional structures: the cellulose cell wall, large permanent vacuoles and chloroplasts. The ultrastructure of an animal cell shows a densely packed cell - the ER and RER and ribosomes form extensive networks throughout the.
