Describe the function of the following :-
• Cell wall
• Cell membrane
• Nucleus
• Ribosomes
• Lysosomes
Answers
Answer:
cell wall.
The cell wall is the protective, semi-permeable outer layer of a plant cell. A major function of the cell wall is to give the cell strength and structure, and to filter molecules that pass in and out of the cell.
cell membrane
The cell membrane, also known as the plasma membrane, is a double layer of lipids and proteins that surrounds a cell and separates the cytoplasm (the contents of the cell) from its surrounding environment. It is selectively permeable, which means that it only lets certain molecules enter and exit
Eukaryotic cells contain a membrane-bound nucleus and numerous membrane-enclosed organelles (e.g., mitochondria, lysosomes, Golgi apparatus) not found in prokaryotes. ... The resulting proteins carry out cell functions. Also located in the nucleus is the nucleolus or nucleoli, organelles in which ribosomes are assembled.
Answer:
Cell wall protect the cell from outside particles and unwanted substance.
Cell membrane helps to pass selectively permeable substances and food materials.
Nucleas is also known as brain of the cell and contains genetic information DNA.
Ribosomes contains RNA which helps cell to synthesise proteins.
Lysosomes contains digestive enzymes that digests excess or worn out particles or engulf bacteria.
