Typical Human Cell Tem Stock Image C028 2388 Science Photo Library The nucleus is a large organelle that contains the cell’s genetic information. most cells have only one nucleus, but some have more than one, and others—like mature red blood cells—don’t have one at all. within the nucleus is a spherical body known as the nucleolus, which contains clusters of protein, dna, and rna. In transmission electron microscopy (tem), electrons are transmitted through a plastic embedded specimen, and an image is formed. tem enables the resolution and visualization of detail not.

Learning objectives. at the end of this unit, you should be able to: i. specify the characteristics associated with life and explain why the cell is the basic unit of life. ii. describe the levels of structural organization in the body. iii. describe the structure and the functions of the major components of a cell. iv. Liquid phase transmission electron microscopy (tem) has recently been developed as a direct imaging method for nanoscale dynamics. although it enables direct tracking of the individual space time trajectories of nanoscale objects in liquid (10–12), the observed motion is often disturbed by electrostatic interactions with substrates, or the medium boundaries, which are caused by electron beam.
