Question

Mitochondria and chloroplasts are______ of cells respectively.
A) Power house and kitchen
B) Guard and power house
C) Kitchen and guard
C) Power house and secretory bags

Answer 1

Hint: Mitochondria helps in breaking down fuel molecules and capturing energy in cellular metabolism. Chloroplasts are responsible for the food preparation for the plant and it is the site of photosynthesis.

Complete answer:
>Mitochondria are also called the powerhouse of the cell and it does not contain any pigment like chloroplasts.
>They are double-membrane structures which are made up of two membranes inner and outer membrane.
>The chloroplast is found in algae and plant cells and does the photosynthesis. Chloroplasts are located in the cytosol of the cell and reproduce independently as they have their own DNA.
>Mitochondria helps in releasing energy from food and chloroplast helps in the synthesis of food.

Functions of Mitochondria and chloroplasts:
>The mitochondrion is a bean-shaped, colourless organelle and known as a powerhouse and the major function is metabolism and cellular respiration.
>Energy is released by breaking food/fuel and generating carbon dioxide and water.
>Chloroplast is a disc-shaped, green colour organelle that consists of chlorophyll, carotenoids, and photosynthetic pigments.
>Chloroplast uses carbon dioxide and water to generate glucose and store energy.

So, the correct answer is Powerhouse and kitchen.<

Note: Mitochondria and chloroplasts do not work together. The oxygen and glucose which is generated by the process of photosynthesis by chloroplasts are required by mitochondria to carry out cellular respiration. Both these organelles are equally important and responsible for the growth of a cell.
