There are two types of cells, prokaryotic and eukaryotic cells; the complex one. Plan ts and animal cells are both eukaryotic cells.

Well, on a daily basis, there are trillions of tiny, microscopic organisms inhabiting out bodies. In fact, the thing about this little creatures is that fact thatwe cannot see them with our naked eyes. So, it feels as if they arent three but all youd think all we need is a little faith to believe. Fortunately, we are equipped with the right tools to understand these little creatures. We are equipped with microscopes! These organisms can be seen using a microscope and not just our naked eyes. Given the fact that this is so, these little organisms are referred to as microscopic organisms, micro-organisms, or just microbes, for short.
Types of MicrobesThere are many types of microbes. Some of these microbes live in soil, some on plants and some even live on our bodies. In fact, microbes are all around us. Many of us get sick at times because of microbes such as bacteria and viruses. As a matter of fact, there are about five (5) main groups of microbes, these include:

have a few common features. Some of these features may include, common organelles small structures within a cell, cell membrane. nucleus, cytoplasm, endoplasmic reticulum etc. There are many differences also which includes, shape, size andstructure. So, are you ready to delve a bit deeper? Lets look at some of the main differences.
ShapeThey can be easily distinguished by their shape. Here are few differences in shape between plants cells and animal cells.
Plant cells have a fixed or definite shape. This shape is due to the rigidity of the cell wall, giving the plant cell a fixed shape.Unlike plant cells animal cells have a round or irregular shape. An irregular shape is so because animal cells arent fortunate enough to get a rigid cell wall or even a cell wall at all. Animal cells do not contain a cell wall, however, only a cell membrane, thus, giving them an irregular shape.StructureLets now look at the various structures when it comes to plant cells vs. animal cells.
Cell WallCell walls are found in plant cells and are not present in animal cells. This gives the plant cell an extra layer of protection and also its shape and stability.
The cell wall is a rigid organelle composed of cellulose; it allows materials to pass to and from the cell membrane.VacuolesVacuoles are membrane-bound organelles since it contains a single membrane. They are found in both plant and animal cells.
Plant cells contain a liquid-filled organelle called the vacuole. Plant cells consist of only on vacuole which takes up about 90% of its volume.Unlike plant cells, animal cells usually consist of one or more vacuoles.In animal cells, vacuoles store water, wastes and ions, whereas, in plant cellsit stores water and maintains turgidity of the cells.ChloroplastChloroplasts are organelles found in plant cells. Since plants are autotrophs, t
hey need cells that contain chloroplast since these chloroplast captures light energy from the sun then converts it into chemical energy. Unlike plants, animals depend on autotrophs in order to survive. So, this is why:
chloroplasts are found in plant cells only;animal cells do not contain chloroplasts.
