Question

7. Cells often store materials like water, salts, proteins and carbohydrates in sac-like structures called A. Chloroplasts. B. Lysosomes. C. Mitochondria. D. Vacuoles.

Answer 1

A

Step-by-step explanation:

the chloroplast holds the water , nutrients

Answer 2

`\boxed {\boxed {\sf D. \ Vacuoles}}`

Step-by-step explanation:

First, let's examine each answer choice.

A. Chloroplasts

• These structures are only found in plant cells. They are the site of photosynthesis: the process that turns water, carbon dioxide, and light energy into glucose and oxygen.

B. Lysosomes

• These help remove and break down cellular waste. They contain special enzymes that allow them to digest certain molecules, bacteria, and old parts of the cell.

C. Mitochondria

• These are famously known as the powerhouse of the cell. They create energy from glucose and oxygen in a process called cellular respiration.

D. Vacuoles

• Vacuoles are sacs that store substances, including water, nutrients, and waste.

Since the question asks us to pick the sac-like structures that store materials in cells, choice D: vacuoles is correct.
