Question

directions: base your answers to questions 2 - 5 on the diagram below and your knowledge of biology.

1. which cell is an animal cell? explain.
2. identify the organelle labeled x.
3. identify the organelle that is where plant cells convert sunlight into nutrients. then, draw an arrow pointing to this structure.
4. which statement best describes these cells? (1) cell b lacks vacuoles while cell a has them. (2) both cell a and cell b use energy atp. (3) dna would not be found in either cell a or cell b. (4) both cell a and cell b produce antibiotics.

directions: base your answers to the questions on the information below and your knowledge of biology.

1. some viruses attack cells by attaching to their outer covering, entering, and then taking over their genetic machinery. viruses are able to invade cells after first attaching to their (1) nucleus (2) genetic machinery (3) cell membrane (4) viral proteins
2. a plant cell is represented in the diagram. select one of the lettered structures. record the letter of the structure chosen and, using one or more complete sentences, state the function of the structure.

Explanation:

Question 2:

Animal cells lack a cell - wall and have an irregular shape. Cell B has an irregular shape and no cell - wall, so it is an animal cell.

Question 3:

The organelle labeled X appears to be the endoplasmic reticulum, which is involved in protein and lipid synthesis.

Question 4:

Chloroplasts are the organelles where plant cells convert sunlight into nutrients (through photosynthesis). In cell A, the chloroplasts can be identified as the green - like structures (drawing an arrow is not possible in this text - based response).

Question 5:

All living cells use ATP for energy. Both cell A (plant cell) and cell B (animal cell) are living cells, so they use ATP. Statement (2) is correct.

Question 6:

Viruses attach to the cell membrane of host cells before invading. So the answer is (3) cell membrane.

Question 7:

If we choose A (cell wall), its function is to provide structural support and protection to the plant cell.

Answer:

1. Cell B is an animal cell because it has an irregular shape and lacks a cell - wall.
2. Endoplasmic reticulum
3. Chloroplasts
4. (2) Both cell A and cell B use energy ATP.
5. (3) cell membrane
6. If A is chosen: The cell wall provides structural support and protection to the plant cell.
