Question 5(Multiple Choice Worth 5 points)
(04.03 LC)

The diagram below shows the structure of an animal cell.

The image of an animal cell is shown with some organelles labeled numerically from 1 to 6. The outer double layer boundary of the cell is labeled 1. A stacked disc like structure is labeled 2. A broad rod shaped structure with an irregular shape inside it is labeled 3. The entire plain section that forms the background of the cell and is within the outer boundary is labeled 4. A small circular shape within the large circular shape is labeled 5. The large central circular shape is labeled 6.

Which number label represents cytoplasm?

1
2
3
4

Which statement about the two cells is correct?

Both cells are plant cells.
Both cells are animal cells.
Cell A is a plant cell and Cell B is an animal cell.
Cell A is an animal cell and Cell B is a plant cell.
Question 7(Multiple Choice Worth 5 points)
(04.03 MC)

What will most likely happen in the absence of a vacuole?

Photosynthesis will not take place.
Genetic information will not be transmitted by the cell.
Energy will not be released during cellular respiration.

Answer 1

Here are the answers to your questions based on the statements provided:

Question 1

• Answer: Both statements are about scientific theories.

Question 2

• Answer: Tissue

Question 3

• Answer: All cells come from other, preexisting cells.

Question 4

• Answer: Eggs of flies in the surroundings

Question 5

• Answer: 4 (Cytoplasm is typically the area within the cell membrane and outside the nucleus.)

Question 6

• Answer: Both cells are plant cells. (Cell A has a cell wall and Cell B has chloroplasts, which are both characteristics of plant cells.)

Question 7

• Answer: The cell will not store food, water, nutrients, and waste. (Vacuoles are primarily responsible for storage.)

Question 8

• Answer: Atoms (Atoms are the smallest unit of matter.)

Question 9

• Answer: Nucleus (The nucleus contains DNA and acts as the control center of the cell.)

Question 10

• Answer: Carbohydrate (Carbohydrates are a primary source of energy for cells.)

Question 11

• Answer: It helped to show that some bacteria are just one cell. (Leeuwenhoek's observations contributed to the understanding of unicellular organisms.)

Question 12

• Answer: It is accepted by a large scientific community. (Scientific theories are generally supported by substantial evidence and accepted among scientists.)

Good luck with your exam!
