A scientist is comparing the outer structure of an onion cell, structure X, to the outer structure of a human skin cell, structure Y. Which generalization is true about the types of structures being examined?
A) Structure X is not living, and structure Y is living
B) Structure X can be found in some human cells, and structure Y can be found in some plant cells.
C) Structure X is only found in plant cells, and structure Y is found in plant and animal cells.
D) Structure X is semipermeable, and structure Y is selectively permeable.

Respuesta :

Structure X is only found in plant cells, and structure Y is found in plant and animal cells.

In the given situation, Structure X is Cellulose whereas Structure Y is Epidermis.

Thus the scientist while comparing it found that Cellulose is only found in plant cell whereas Epidermis can be seen in both the Plant and Animal cells.

What are the difference between Plant and Animal cells?

1. Cell shape- Plant Cells are square or rectangular whereas Animal cells are irregular or round.

2. Cell Wall- It is present in Plant cell whereas absent in Animal cells.

3. Nucleus- Lies on one side of the cell in Plant Cell whereas it lies in center in Animal cell.

4. Lysosomes- Present in Plant cell in rare quantity whereas in Animal Cell it is in larger amount.

5. Centrosomes- Absent in Plant cell but present in Animal Cell

6. Plastids- Present in plant cell but absent in Animal cell

7. Mitochondria- Present in fewer number in Plant Cell but larger number in Animal Cell

8. Mode of Nutrition- Plant cells are primarily autotrophic whereas in Animal cell, it is Heterotrophic.

What is Cellulose?

Cellulose is one of the main  components of the Cell wall and is an important regulator of cell wall growth and mechanics.

The shape, size, and crystallinity of Cellulose are important structural parameters that influence mechanical properties of the cell wall and these parameters are  important determinants of cell wall digestibility for biofuel conversion.

Cellulose–cellulose and cellulose-matrix interactions also contribute to the regulation of the mechanics and growth of the cell wall.

What is Epidermis?

Epidermis is the outermost layer of skin on your body which protects the body from harm, keeps the body hydrated, produces new skin cells and contains melanin, which determines the color of  skin.

It is present both in Plant and Animal cells.

Function of Epidermis are:

- Hydration - Provides hydration by holding water and keeps the skin hydrated.

- Producing new skin cells

- Protection from UV radiation, Pathogens and Chemicals

- Provides skin color.
