~A large, round organelle visible under the microscope.
• Controls the cell’s activities
• Controls cell reproduction
Contains genetic material - DNA that makes up the genes and chromosome.
The Ribosome: ~Made of dozens of different proteins as well as RNA, also found in large numbers in the cytoplasm of living cells. Ribosome are typically composed of two subunits:
• Large subunit
• Small subunit
“ Free” Ribosome makes proteins that remain inside the cell,
“Bound’’ Ribosome make proteins that are exported from the cell.
~Protein Synthesis ~Chemical reactions is molecules that are brought into contact with one another.
• Transcription (uses a different type of nucleic …show more content…
Homeostasis is the ability to maintain the internal stability in an organism to compensate for the environment changes. The cell maintains homeostasis by controlling the movements of substances across the cell membrane. The cell membrane is found on the outside of the cell and controls what goes in and out of the cell. It is selectively permeable. The membrane has cells that share common structural features, including an outer boundary. All cells are contained by a cell membrane, which keeps the pieces inside. It consists of a phospholipid bilayer with proteins embedded throughout. It separates what’s inside the cell, some of the proteins. The plasma membrane helps maintain homeostasis by keeping the cell 's contents inside and other foreign material outside of the cell. It maintains the desired environment of the cell, allowing correct processing and packaging inside the cell. The plasma membrane is the boundary between the cell and its environment and regulates what enters and leaves the cell. The fundamental structure of the membrane is the phospholipid bilayer. Cells must maintain an appropriate amount of molecules in order to function inside them. The plasma membrane consists of both lipids and proteins. Nucleus is the special function and surrounded by the membrane that protects it from the rest of the …show more content…
It’s an organelle found in a large number of cells, where the biochemical processes of respiration and energy production occur. It also has a double membrane, the inner layer being folded inward to form layers. Mitochondria are made of two membranes in the outer membrane covers the organelle and contain its skin as the inner membrane folds over many times and create layered structures. The energy made is called ATP. ATP stands for adenosine triphosphate. It’s a single nucleotide with two extra energy storing phosphate groups. When food molecules are broken down inside cells, some of the energy in the molecules is stored temporarily in ATP. Cells need a steady supply of ATP to
