Detailed explanation-1: -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.
Detailed explanation-2: -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.
Detailed explanation-3: -The organelles found only in plant cells include-chloroplast, cell wall, plastids, and a large central vacuole. The chloroplasts contain a green pigment chlorophyll that is responsible for the process of photosynthesis.
Detailed explanation-4: -The nucleus controls all cellular functions. Chromosomes are large molecules in the nucleus made up of DNA and protein. Mitochondria are the factory and storage center for ATP, which is used as energy by the cell in making cellular products and carrying out the functions of the cell.
Detailed explanation-5: -The cellular components are called cell organelles. These cell organelles include both membrane and non-membrane bound organelles, present within the cells and are distinct in their structures and functions. They coordinate and function efficiently for the normal functioning of the cell.
