Organelles are small structures within the cytoplasm that carry out functions necessary to maintain homeostasis in the cell. They are involved in many processes, for example energy production, building proteins and secretions, destroying toxins, and responding to external signals.
What are the functions of cell organelles?
Core organelles They carry out essential functions that are necessary for the survival of cells – harvesting energy, making new proteins, getting rid of waste and so on. Core organelles include the nucleus, mitochondria, endoplasmic reticulum and several others.
What are the basic functions of organelles?
An organelle is a subcellular structure that has one or more specific jobs to perform in the cell, much like an organ does in the body. Among the more important cell organelles are the nuclei, which store genetic information; mitochondria, which produce chemical energy; and ribosomes, which assemble proteins.
How many types of cell organelles are there?
6 Cell OrganellesNucleus. nucleus; animal cell. Ribosomes. Ribosomes are the protein factories of the cell. Endoplasmic reticulum. Ribosomes on the outer surface of the endoplasmic reticulum play an important role in protein synthesis within cells. Golgi apparatus. Golgi apparatus. Chloroplasts. Mitochondria.
