EVERYDAY SCIENCE

Detailed explanation-1: -Cytoplasm of a cell is not an organelle. It is a jelly like substance present between the nucleus and the cell membrane of the cell.

Detailed explanation-2: -Cardiac muscle cells also contain mitochondria, which many people call “the powerhouses of the cells.” These are organelles that convert oxygen and glucose into energy in the form of adenosine triphosphate (ATP). Cardiac muscle cells appear striated or striped under a microscope.

Detailed explanation-3: -Examples of organelles are the nucleus (a structure that contains the cell’s chromosomes and is where RNA is made), mitochondria (structures that make energy for the cell), and lysosomes (sac-like containers filled with enzymes that digest and help recycle molecules in the cell).

Detailed explanation-4: -Nucleus is the organelle which is called as the ‘Headquarter of the cell’ because it gives the instruction to other cell organelles to work. It controls the functioning of the entire cell like growth, reproduction, metabolism as it contains genetic material, which carries information for these functions.
