The smooth endoplasmic reticulum is the organelle responsible for the production of lipids in the cell. This particular reticulum also synthesizes carbohydrates and steroid hormones.Know More
The endoplasmic reticulum is made up of membranous sacs and tubules. It has two different portions: the smooth endoplasmic reticulum and the rough endoplasmic reticulum. The rough endoplasmic reticulum is studded with ribosomes and produces proteins that are incorporated into cellular membranes outside of the cell.
The smooth endoplasmic reticulum lacks ribosomes on its cytoplasmic surface. It is especially important in muscle cells, where the specialized sarcoplasmic reticulum stores calcium ions, which are needed for triggering contraction of muscle cells.Learn more in Cells
The organelle commonly referred to as the powerhouse of the cell is the mitochondria. This structure is the site for the production of adenosine triphosphate, or ATP, a high-energy molecule that drives various cellular processes essential for the survival of an organism. The process of ATP production is known as respiration.Full Answer >
The organelle that manages cell functions in a eukaryotic cell is the nucleus. Most eukaryotic cells have a single nucleus; however, some organisms may have several nuclei per cell.Full Answer >
An important organelle in the division of animal cells is the centrosome. The centrosome is the microtubule generating and organizing center of the cell. Microtubules form the support structure, or cytoskeleton, of all cells. During cell division, or mitosis, microtubules form the spindle fibers that separate chromosomes.Full Answer >
The largest organelle in plant cells containing the cell sap is the vacuole. Plant cells usually have a single vacuole that can take up 80 percent or more of the volume of a cell.Full Answer >
