Cells and Organelles

Cells are the smallest pieces of living things and are the basic unit of life. Cells may be categorized into two different groups: prokaryotes and eukaryotes. Prokaryotes and eukaryotes have some distinctive differences among themselves that make them function and be located in different organisms.

Prokaryotes are bacteria and cyanobacteria (known as blue-green algae) found in the monera Kingdom. The basic structures of eukaryotes are the cell wall, cell membrane, ribosomes, mososomes, pili and a ring of DNA. These divide through the process of binary fission, they do not have chloroplasts or mitochondria and usually most of bacteria have a very strong capsule in the exterior layer that helps them resist into different environments.

On the other hand, eukaryotes are the cells found in plants, animals, fungi and in other macro organisms. These apart from the prokaryotic cells can be divided into plant cells; structured by chloroplasts, cell wall, cell membrane, a nucleus, a vacuole, mitochondria, Golgi body; and animal cells which are structured by plasma membrane, cytoplasm, lysosomes, microvilli, a nucleus, mitochondrion, ribosomes, Golgi apparatus, microfilaments, among others.

During the practical both eukaryotic cells were studied through the microscope lenses. I was able to nourish my knowledge about cells, apply my abilities while using a microscope, identifying several structures in the cells, such as the cell wall, nucleus and cytoplasm and find several differences between the cells.

Both animal and plant cells had clear differences among their structures. As it is shown in the diagram #1 exposed previously, it is evident that plant cells have a quadrilateral shape, while animal cells exposed in diagram #2 have a circle like shape. Moreover, it was recognized that plant cells are really close together, while animal cells are more distant between each other. Additionally I was able to observe that plant cells tend to...
