Detailed explanation-1: -Cells which have membrane bound distinct structures called organelles like nucleus, endoplasmic reticulum (ER), Golgi complex, lysosomes, mitochondria, microbodies and vacuoles are eukaryotic cells. Eukaryotic cells are found in all protists, plants, animals and fungi.
Detailed explanation-2: -Membrane-bound organelles are cellular structures that are bound by a biological membrane. The membrane may be a single layer or a double layer of lipids and typically with interspersed proteins.
Detailed explanation-3: -Microbodies. Microbodies are membrane-bound, minute, vesicular organelles, found in both plant and animal cells. They contain various enzymes and proteins and can be visualized only under the electron microscope.
Detailed explanation-4: -A small structure in a cell that is surrounded by a membrane and has a specific function.
Detailed explanation-5: –The mitochondria and the chloroplast are the double membrane-bound organelles and are filled by fluid in the intermembrane space. These cell organelles have their own DNA, RNA, ribosomes, and certain enzymes.
