Figure 2 (a) A transmission electron microscope. (b) A transmission electron micrograph of a frog leukocyte (white blood cell). The nucleus and nucleolus (Section 4.3), mitochondria (Section 4.10) and Golgi apparatus (Section 4.7) can be seen. The dark area of the nucleus contains densely packed DNA. Show description.

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.

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.

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.

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.

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.

Animal cell. Transmission electron micrograph of part of a mouse liver cell. In the lower frame is the cell nucleus, bound by a delicate nuclear membrane. Holes in the membrane (at right, for example) allow large molecules to pass out into the cell cytoplasm. The dark grey circles above the nucleus are mitochondria, where fats and sugars are.

Prokaryotic cells like bacteria have no nucleus and fewer organelles than eukaryotic cells, which form plants and animals. Electron Micrographs Basic Understanding. An electron micrograph is a type of image created using electron microscopy. It provides high-resolution images allowing for detailed study of cell structures, including cell.
