difference between nucleus and nucleous ,cytoplasm and protoplasm ,cell wall and cell membrane
Answers
Answer:
nucleus is cell organelle which contains genetic material whereas nucleolus is found inside nuclear ,it's unbound and site for RNA and protein synthesis.
protoplasm is inner content of cell minus cell membrane where as cytoplasm is inner cell content excluding nucleus
cell wall is extra covering of cell ,non living and after cell membrane.
cell membrane bounds the cell and is living bilayer of phospholipid where as cell wall is of cellulose
The cell nucleus (plural: cell nuclei) is a membrane bound structure that contains the cell's genes and controls the cell's growth and reproduction. It is usually the most prominent organelle in a cell. The human body contains billions of cells, most of which have a nucleus.
The nucleolus makes ribosomal subunits from proteins and ribosomal RNA, also known as rRNA. It then sends the subunits out to the rest of the cell where they combine into complete ribosomes. Ribosomes make proteins; therefore, the nucleolus plays a vital role in making proteins in the cell.
The organelles of eukaryotic cells, such as mitochondria, the endoplasmic reticulum, and (in green plants) chloroplasts, are contained in the cytoplasm.
Protoplasm is composed of a mixture of small molecules such as ions, amino acids, monosaccharides and water, and macromolecules such as nucleic acids, proteins, lipids and polysaccharides. In eukaryotes the protoplasm surrounding the cell nucleus is known as the cytoplasm and that inside the nucleus as the nucleoplasm.
The primary function of the plasma membrane is to protect the cell from its surroundings. Composed of a phospholipid bilayer with embedded proteins, the plasma membrane is selectively permeable to ions and organic molecules and regulates the movement of substances in and out of cells.
