Plants change the ______________ into food energy
- A.
Atmosphere's energy
- B.
Moon's energy
- C.
Sun's energy
- D.
Ocean's energy
Correct Answer
C. Sun's energyExplanation
Plants convert the Sun's energy into food energy through the process of photosynthesis. During photosynthesis, plants use sunlight, carbon dioxide, and water to produce glucose (sugar) and oxygen. The Sun's energy is absorbed by the chlorophyll in plant cells, which then converts it into chemical energy in the form of glucose. This glucose is used as a source of energy for the plant's growth and development. Therefore, the Sun's energy is essential for plants to produce food and sustain life on Earth.Rate this question:

Living plants are _______________
- A.
Sometimes growing
- B.
Always growing
- C.
Not alive
- D.
Decomposers
Correct Answer
B. Always growingExplanation
Living plants are always growing because they have the ability to undergo continuous growth throughout their lifespan. This growth is mainly due to cell division and elongation in various parts of the plant, such as stems, leaves, and roots. Plants require growth to adapt to their environment, obtain nutrients, and reproduce. Unlike animals, plants have indeterminate growth, meaning they can continue to grow throughout their lives as long as they have access to the necessary resources and conditions.Rate this question:

Mosses and ferns live mostly in environments that are
- A.
Moist
- B.
Hilly
- C.
Windy
- D.
Cold
Correct Answer
A. MoistExplanation
Mosses and ferns live mostly in moist environments because they require a constant supply of water to survive and reproduce. Moisture is essential for their growth and development as they lack a vascular system to transport water and nutrients like other plants. This is why they are commonly found in areas such as rainforests, wetlands, and shady areas with high humidity levels. The presence of moisture helps these plants to absorb water and nutrients directly from their surroundings, enabling them to thrive in such environments.Rate this question:
