Questions: Cell Type Dichotomous Key 1a cell has a nucleus and organelles → go to step 2 1b cell has no nucleus or organelles → bacterial cell 2a cell has a cell wall → go to step 3 2b cell has no cell wall → animal cell 3a cell has chloroplasts → plant cell 3b cell has no chloroplasts → fungal cell What type of cell is cell A? A animal B bacterial C fungal D plant

To determine the type of cell that cell A is, we need to follow the dichotomous key provided in the question. Let's go through the steps:

1. Step 1:

   • If the cell has a nucleus and organelles, go to step 2.
   • If the cell has no nucleus or organelles, it is a bacterial cell.

   Since cell A is not specified to lack a nucleus or organelles, we assume it has them. Therefore, we proceed to step 2.

2. Step 2:

   • If the cell has a cell wall, go to step 3.
   • If the cell has no cell wall, it is an animal cell.

   Since cell A is not specified to lack a cell wall, we assume it has one. Therefore, we proceed to step 3.

3. Step 3:

   • If the cell has chloroplasts, it is a plant cell.
   • If the cell has no chloroplasts, it is a fungal cell.

   Since cell A is not specified to have chloroplasts, we assume it does not have them. Therefore, cell A is a fungal cell.

Summarizing the answer:

The answer is C: fungal

Explanation for each option:

• A: animal - Incorrect. An animal cell does not have a cell wall.
• B: bacterial - Incorrect. A bacterial cell does not have a nucleus or organelles.
• C: fungal - Correct. A fungal cell has a cell wall but no chloroplasts.
• D: plant - Incorrect. A plant cell has chloroplasts.

Thus, based on the dichotomous key, cell A is a fungal cell.
