How can you tell a plant cell from an animal cell?
- A.
Cell wall, chloroplasts
- B.
Nucleus, organelles
Correct Answer
A. Cell wall, chloroplastsExplanation
A plant cell can be distinguished from an animal cell by the presence of a cell wall and chloroplasts. The cell wall provides structural support and protection to the plant cell, while animal cells do not have a cell wall. Chloroplasts are responsible for photosynthesis, which is a process unique to plant cells. Animal cells do not contain chloroplasts. The presence of these two features, cell wall and chloroplasts, is a clear indication that the cell in question is a plant cell.Rate this question:

- A.
A green pigment
- B.
A chemical that puts people to sleep
Correct Answer
A. A green pigmentExplanation
Chlorophyll is a green pigment found in plants and algae that is responsible for the absorption of light during photosynthesis. It plays a crucial role in converting sunlight into energy, allowing plants to produce glucose and oxygen. The green color of chlorophyll is due to its ability to absorb red and blue light while reflecting green light. It is essential for the growth and development of plants and is what gives them their characteristic green color.Rate this question:

What purpose does the root of a plant serve?
- A.
Gives plants their green color
- B.
Helps the plant stay in place and get nutrients from the soil
Correct Answer
B. Helps the plant stay in place and get nutrients from the soilExplanation
The root of a plant serves the purpose of helping the plant stay in place and obtain nutrients from the soil. Roots anchor the plant in the ground, providing stability and preventing it from being easily uprooted. They also absorb water and minerals from the soil, which are essential for the plant's growth and survival. Therefore, the root system plays a crucial role in the overall health and well-being of the plant.Rate this question:

What part of a flower helps it attract other organisms?
- A.
The petal
- B.
The stem
Correct Answer
A. The petalExplanation
The petal of a flower helps attract other organisms such as insects, birds, and mammals. Petals are often brightly colored and have unique patterns or markings that serve as visual cues. They may also produce fragrances or nectar to further entice pollinators. These attractive features help the flower in the process of pollination, as organisms are drawn to the flower, come into contact with its reproductive structures, and aid in the transfer of pollen.Rate this question:

What are angiosperms?
- A.
Flowering plants
- B.
Seed-bearing plants
Correct Answer
A. Flowering plantsExplanation
Angiosperms are a group of plants that are characterized by their ability to produce flowers. These flowers contain reproductive structures, such as ovaries and stamens, which eventually develop into fruits and seeds. This distinguishes angiosperms from other plants, such as gymnosperms, which do not produce flowers. Therefore, the correct answer that best defines angiosperms is "flowering plants."Rate this question:
