Nucleus:
The nucleus is the control centre of the cell. It’s much like a blueprint that contains all of the instructions on building the body. It contains genetic material called DNA. This DNA has instructions for building proteins and is essential to cell reproduction. If a cell doesn’t have a nucleus for whatever reason will certainly die. The nucleus conforms to the shape of the cell so it could be oval or it could be spherical. The nucleus has three recognizable regions; the nuclear envelope, nucleoli and chromatin.
Nucleolus:
These are small, dark, round bodies that are grouped, in the middle of the nucleus. They are sites where ribosomes are formed. The ribosomes eventually make their way to the cytoplasm, serving for protein synthesis. …show more content…
There’s the smooth part and the rough part. The ER is a network in the cytoplasm. It’s a system of fluid-filled tubules and canals that coils, twists and turns throughout the cytoplasm. It carries proteins through one part of the cell to another. The rough ER is bumpy or studded with ribosomes. The building materials are either build on it of in it. This is also known as the cell’s membrane factory. Pancreas cells are abundant with rough ER. The smooth ER doesn’t work with proteins. It works with lipids instead. The smooth ER is a key factor in lipid metabolism, or cholesterol and fat synthesis and breakdown. It’s also a key factor in detoxification of drugs and pesticides. Liver cells are abundant with smooth ER. Body cells need smooth ER for breakdown of hormones or steriods - cells of the male testes with testosterone.
Ribosomes: These are tiny dark bodies made of up proteins and only one variety of RNA called ribosomal RNA. Ribosomes are site of protein synthesis. Some float free in the cytoplasm where they make more proteins that function in the cytoplasm. Other attach to membrane which results in the name rough endoplasmic …show more content…
These are tiny thread-like, or sausage shaped organelles. In living cells they move constantly and change shape continuously. The wall of the mitochondria is a double membrane layer, which is very thick. This membrane is equal to two plasma membranes. The outside is smooth, but the inside the wall it has cristae “crests”. Food breaks down, energy is released. Some energy is heat, and others are ATP molecules. The mitochondria supply most of the ATP to the cell, which is why it’s the “powerhouse”. These can “pinch” in half to
