Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Which of the following lists only membrane-bound organelles?
A
mitochondria, cilia, centrioles, Golgi apparatus, endoplasmic reticulum, nucleus
B
endoplasmic reticulum, Golgi apparatus, mitochondria, lysosomes, peroxisomes
C
lysosomes, ribosomes, peroxisomes, endoplasmic reticulum, Golgi apparatus
D
microtubules, nucleus, lysosomes, ribosomes, mitochondria, cilia
Explanation: 

Detailed explanation-1: -Endoplasmic reticulum, peroxisome, Golgi apparatus and vacuole are single membrane bound organelles.

Detailed explanation-2: -Examples of membrane-bound organelles are nucleus, endoplasmic reticulum, Golgi apparatus, mitochondria, plastids, lysosomes, and vacuoles.

Detailed explanation-3: -Single membrane-bound organelles: Vacuole, Lysosome, Golgi Apparatus, Endoplasmic Reticulum are single membrane-bound organelles present only in a eukaryotic cell. Double membrane-bound organelles: Nucleus, mitochondria and chloroplast are double membrane-bound organelles present only in a eukaryotic cell.

Detailed explanation-4: -Peroxisomes are single-membrane–bounded organelles found in nearly all eukaryotic cells. In plant cells, peroxisomes are involved in a variety of metabolic pathways essential for development associated with photorespiration, lipid mobilization, and hormone biosynthesis (1, 2).

Detailed explanation-5: -Lysosomes are membrane-enclosed organelles that contain an array of enzymes capable of breaking down all types of biological polymers-proteins, nucleic acids, carbohydrates, and lipids.
