GENERAL HISTOLOGY

Detailed explanation-1: -An organelle (think of it as a cell’s internal organ) is a membrane bound structure found within a cell. Just like cells have membranes to hold everything in, these mini-organs are also bound in a double layer of phospholipids to insulate their little compartments within the larger cells.

Detailed explanation-2: -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-3: -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.

Detailed explanation-4: -They are responsible for the synthesis of substances like lipid, protein, starch, etc. Cell organelles generate energy. They secrete hormones, enzymes, etc. They are involved in the digestion of substances taken up by the cell.
