Most bacterial size range from 0.2 to 2.0 μm in diameter and 2 to 8 μm in length.  The ubiquitous Escherichia coli is about 1 μm in diameter and 1-2  μm long. The world’s biggest bacteria, Thiomargarita magnifica is up to 2 cm long and is visible to the naked eye.

Different types of plant tissues include meristematic (growing) and permanent tissues.

Likewise, different types of animal tissues include epithelial, muscle, nervous, and connective tissues. From skin to skeletons, these different types of tissues are present in animals.

Plastids are present in all living plant cells and some protozoans (Euglena). These are small bodies with double membranes, approximately spherical or disc-shaped, and 1 µm to 1 mm in diameter. Plastids may also appear elongated, lobed, or amoeboid in shape.
