CELL STRUCTURES AND FUNCTION

CELL ORGANELLE

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Cells have similar characteristics as living things. For example, vacuoles in a plant cell function to store water, and similarly, the gall bladder in animals stores bile. Which of the following pair structures DO NOT have similar functions?
A
small intestine, endoplasmic reticulum
B
brain, nucleus
C
epidermis, cell membrane
D
stomach, mitochondrion
Explanation: 

Detailed explanation-1: -A plant cell contains a large, singular vacuole that is used for storage of water and nutrients. It also helps maintain the shape of the cell. In contrast, animal cells have many, smaller vacuoles, which also are used for storage of water and nutrients.

Detailed explanation-2: -Structurally, plant and animal cells are very similar because they are both eukaryotic cells. They both contain membrane-bound organelles such as the nucleus, mitochondria, endoplasmic reticulum, golgi apparatus, lysosomes, and peroxisomes. Both also contain similar membranes, cytosol, and cytoskeletal elements.

Detailed explanation-3: -Lysosomes are basically small bags of membrane containing enzymes, so they look structurally similar to a small vacuole.

Detailed explanation-4: -Instead of the large “vacuolar” organelles that are found in plants and fungi, animal cells possess lysosomes that are smaller in size and are enriched with hydrolytic enzymes similar to those found in the vacuoles.
