Which statement describes ALL prokaryotic and eukaryotic cells?

• Ribosomes are present in the cytoplasm.
• Materials are stored in vacuoles.
• Chloroplasts are used for photosynthesis.
• Cell walls provide shape and support.

Melinda had two slides of unknown cells. She recorded her observations of each one on the chart below. According to the information in the given chart, what type of cell is cell X?

• Bacteria Cell
• Prokaryotic Cell
• Plant Cell
• Animal Cell

The simplicity of prokaryotic cells prevents them from

Examine the following specialized muscle cells found in animals. Why would it be necessary for a muscle cell to have a higher percentage of mitochondria than other cells in the body?

• To make proteins
• To provide energy for movement
• To store water and nutrients
• To convert light energy into carbohydrates
