Unit 1 review- Moore-2024 2025

A student looks at cells under the microscope. The cells might be from a plant or an animal. The picture below is what the student sees. The cells must be plant cells because the student sees which of these cell parts?

• nuclei

• chloroplasts

• mitochondria

• cell membranes

Examine the image and answer the question. Evaluate the model above and select three statements that describes a limitation of the model. Pick up to 3 answers.

• The model helps in the understanding of the parts of a cell.

• The model accurately shows the size of the cell.

• The model shows the different activities within a cell.

• The model shows how cells are working together in an organism.

A student observed two different types of cells under a microscope. She noticed that one cell had many more mitochondria than the other. What can the student predict about the cell with more mitochondria?

• The cell produces more waste.

• The cell makes more proteins.

• The cell responds to more external stimuli.

• The cell undergoes more cellular respiration.

Select the correct answer. Click on the organelle that transports proteins because it is responding to signals throughout the cell.

• Nucleus

• Ribosome

• Endoplasmic Reticulum

• Golgi Apparatus

Which statement best describes all components of the cell theory?

• One scientist was credited for the development of the cell theory.

• Makes relationships between cells and living things.

• Explains the size of cells and their need for energy.

• Developed before the use of microscope technology, and based solely on the discoveries of scientists.
