Hello readers,
These past weeks in our sicence class we’ve been looking at something called an “animal cell”. What’s that excatly? They are four cell components called Nucleus, cell membrane, cytoplasm and mitochondria.
Nucleus
The nucleus is found in most eukaryotic cells, the exception being red blood cells. In animal cells it is both the largest and stiffest and is easily identifiable by light microscopy. The average mammalian nucleus has a diameter of ~6µm and occupies about 10% of the total cell volume.
Cell membrane
The cell membrane is a biological membrane that separates and protects the interior of all cells from the outside environment.
Cytoplasm
Cytoplasm is the gelatinous liquid that fills the inside of a cell. It is composed of water, salts, and various organic molecules. Some intracellular organelles, such the nucleus and mitochondria, are enclosed by membranes that separate them from the cytoplasm.
Mitochondria
Mitochondria are membrane-bound cell organelles (mitochondrion, singular) that generate most of the chemical energy needed to power the cell’s biochemical reactions.
