Which of the following is smaller than an organelle?
a. An organ
b. A cell
c. A molecule
d. A tissue
Introduction:
An organelle is a particular structure within the cell that plays a unique function. Cellular organelles are found only in the eukaryotic cells, not in the prokaryotic cells. Organelles are either single membrane-bound or double membrane-bound or non-membrane bound. Single membrane-bound organelles are lysosomes, vacuoles, Golgi complex, and endoplasmic reticulum, whereas double membrane-bound organelles are mitochondria, chloroplast, and nucleus. They are present in the eukaryotic cells. Ribosomes are non-membrane bound and it is found in both prokaryotic and eukaryotic cells. Cellular organelles are only visible through the microscope.
Answer to Problem 1MCQ
Correct answer:
A molecule is smaller than an organelle. Hence, option c. is correct.
Explanation of Solution
Reason for correct answer:
Option c. is given as “A molecule.”
Atoms bond together to form molecules. These molecules form the organelles inside a cell. An organism consists of one or more cells. In most multicellular organisms, cells form tissues and then organs and organ system. Hence, option c. is correct.
Reasons for incorrect answers:
Option a. is given as “An organ.”
An organ is made up of a group of tissues, and responsible for specific function in the body. Major organs are lungs, liver, heart, kidney, and brain. In higher animals, organs are grouped together to form organ system. Thus, an organ is not smaller than an organelle. Hence, option a. is incorrect.
Option b. is given as “A cell.”
A cell is a structural and functional unit of all living organism. Cells are the building blocks of life. Cells are divided into two types: (a) prokaryotic and (b) eukaryotic cells. Organelles are present inside a eukaryotic cell. So, a cell is not smaller than an organelle. Hence, option b. is incorrect.
Option d. is given as “A tissue.”
A tissue is made up of a group of cells and these tissues are involved in the formation of organs. So, a tissue is not smaller than an organelle. Hence, option d. is incorrect.
Because of the reasons as mentioned earlier, a molecule is smaller than an organelle
