Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
This cell organelle is found both in plant and animal cells and consists of a system of membranes that is found in the cell’s cytoplasm and assists in the production, processing, and transport of proteins and in the production of lipids.
A
mitochondria
B
endoplasmic reticulum
C
golgi complex
D
lysosome
Explanation: 

Detailed explanation-1: -The endoplasmic reticulum (ER) is a network of membrane-enclosed tubules and sacs (cisternae) that extends from the nuclear membrane throughout the cytoplasm (Figure 9.1). The entire endoplasmic reticulum is enclosed by a continuous membrane and is the largest organelle of most eukaryotic cells.

Detailed explanation-2: -A nucleus is an organelle that is present in both plant and animal cells. It controls all the activities of the cell. Cell wall and chloroplasts are present only in plant cells.

Detailed explanation-3: -Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell. In cellular respiration sugar with the help of oxygen is broken down into ATP (energy molecule).
