Cells, the basic unit of life as stated by the cell theory first created by Theodor Schwann and Matthias Jakob Schleiden, are what make up most living things. They are the blueprint to all life, and are what make up each and every organism, from a simple bacteria cell to humans and all animals. The Cell has two main types; prokaryotic and eukaryotic. These two types differ in slight ways, which makes them unique to their own organisms.

Prokaryotic Cells are cells without a nucleus, which is an area of the cell that's supposed to store DNA and Chromosomes. Without the nucleus, Prokaryotic Cells have free floating DNA in the Cytoplasm. Prokaryotic cells are typically what make up unicellular

All cells come from preexisting cells, 2. Cells are the basic unit of life, 3. All living organisms are consisted of one or more cells, from unicellular to multicellular organisms. The Cell Theory is usually credited to Matthias Schleiden and Theodore Schwann, though many others, such as Rudolf Virchow, contributed to the Cell Theory. The Cell Theory is the main source of explaining the source of cells, as well as their use as to why they are components to…show more content…
These organelles include: the mitochondria, ribosomes, endoplasmic reticulum, and the vacuole. Plant cells have an extra organelle that animal cells don't have, which is the chloroplast. The Chloroplast is an organelle which helps give plants the green color, as well as the center for the process known as photosynthesis. Organelles are what help the cell survive and live. Each organelle has it's own specific role. The Nucleus, located in eukaryotic cells only, holds the chromosomes of an organism, or it's DNA (Deoxyribose Nucleic Acid). The Mitochondria, also known as the powerhouse of the cell, creates energy for the cell. The Vacuole is basically a storage, storing food and water for the cell to use later on. The cell membrane allows things in and out of the cell, acting as the gate, along with the cytoplasm, which holds all organelles in place within the cell.

Different Cells (Tissue/Organs)

Cells in organisms, such as humans, plants, and fungi, have different functions based upon their location within the being. For example, blood cells carry oxygen throughout the body, and are created within the bone marrow. This allows oxygen to reach areas of the body where it's necessary, keeping us going.

Two main different cell types include somatic cells and gamete cells, somatic cells are body cells while gametes are reproductive. Somatic cells sit on 46 chromosomes while
