Question

1. sydney created a cell model for her science project as shown below. sydney needs to label her model. which statement best describes the type of model sydney created? a. sydney has created a plant cell model because only plant cells contain chloroplasts and a cell wall. b. sydney has created an animal cell model because only animal cells contain a nucleus and a cell wall. c. sydney has created a plant cell model because only plant cells contain cytoplasm and a cell membrane. d. sydney has created an animal cell model because only animal cells contain chloroplasts and a cell membrane.

Explanation:

To determine the correct answer, we analyze the cell model's features (cell wall, chloroplasts) and cell type characteristics:

• Plant cells have cell walls, chloroplasts, nuclei, cytoplasm, and cell membranes. Animal cells lack cell walls and chloroplasts.
• Option A: The model has chloroplasts (plant - specific) and a cell wall (plant - specific). Plant cells contain chloroplasts (for photosynthesis), and only plant cells have cell walls. This matches the model's features.
• Option B: Animal cells do not have cell walls, so this is incorrect.
• Option C: Both plant and animal cells have cytoplasm, so this reasoning is wrong.
• Option D: Animal cells do not have chloroplasts, and the model has a cell wall (animal cells lack cell walls), so this is incorrect.

Answer:

A. Sydney has created a plant cell model because only plant cells contain chloroplasts and a cell wall.
