Nucleolus - a small dense spherical structure in the nucleus of a cell during inter-phase.
The nucleolus’s function is to arrange and modify ribosomal RNA and combine ribosomal proteins to form immature ribosomes.
The structure is contained within the nucleus and is dense, composed of RNA and proteins called the nucleolus. The nucleolus contains nucleolar organizers, which are parts of chromosomes with the genes for ribosomal synthesis on them.
Nucleus - the central and most important part of an object, movement, or group, forming the basis for its activity and growth.
The nucleus’s function is to maintain the integrity of the genes and to control the activities of the cell by regulating gene expression — the nucleus is therefore the control center of the cell.
The nucleus structure is bound by a double membrane called the nuclear envelope. The membrane separates the parts of the nucleus from the cytoplasm. Like the cell membtrane, the nuclear envelope consists of phospholipids. The envelope helps to maintain the shape of the nucleus and assists in regulating the flow of molecules into and out of the nucleus through nuclear pores.
Ribosome - a minute particle consisting of RNA and associated proteins, found in large numbers in the cytoplasm of living cells.
A function that the ribosome has is that they assemble amino acids to form specific proteins and also send genetic messages from the mRNA which are translated into proteins during the DNA translation. ribosomes also export the polypeptide produced to the cytoplasm where it will form a functional protein.
Ribosomes in a cell are located in two regions of the cytoplasm, they are found scattered in the cytoplasm and some are attached to the endoplasmic reticulum and are tiny particles composed with RNA and protein. Consist of two major components — the small ribosomal subunit which reads the RNA, and the large subunit which joins amino acids to form a polypeptide chain.
Vacuole - a space or vesicle within the cytoplasm of a cell, enclosed by a membrane and typically containing fluid.
Some functions that the vacuole has is that it Isolates materials that might be harmful or a threat to the cell and Contains waste products. It also exports unwanted substances from the cell and contains small molecules.
The structure of the vacuole is a membranous sac that crowds the cytoplasm and organelles to an edge of the cell, It stores water and proteins. It also contains waste and there’s a membrane that surrounds a mass of fluids.
