Photosynthesis/Respiration/Mitosis

The primary source of energy for all living things is _________.

• sunlight
• Food

• Trees

• McDonalds

Answer explanation

The primary source of energy for all living things is sunlight. It drives photosynthesis in plants, which forms the basis of the food chain, providing energy for other organisms.

Plants make their own glucose (sugar) by the process of _________.

• photosynthesis
• Cellular Respiration

Answer explanation

Plants make their own glucose through photosynthesis, a process that converts sunlight, carbon dioxide, and water into sugar and oxygen, providing energy for growth.

What two raw materials do plants need to do the process of photosynthesis? _________ and _________.

• carbon dioxide, water
• water, carbon dioxide

• oxygen, carbon dioxide

Answer explanation

Plants need carbon dioxide and water to perform photosynthesis. Carbon dioxide is absorbed from the air, while water is taken up from the soil, both of which are essential for converting light energy into chemical energy.

Where do plants get the energy they need to do the process of photosynthesis? _________.

• sunlight
• sugar

• water

Answer explanation

Plants get the energy they need for photosynthesis from sunlight. This process allows them to convert light energy into chemical energy, which is essential for their growth and survival.

What part of the plant makes the most sugar (glucose)? _________.

Answer explanation

The leaves are the primary site of photosynthesis in plants, where sunlight is converted into chemical energy, producing glucose. Therefore, leaves make the most sugar (glucose) in a plant.

What part of the plant will absorb the most light?

• Roots

• Stems

• Leaves

Answer explanation

Leaves are the primary site for photosynthesis in plants, containing chlorophyll that absorbs sunlight. This makes them the part of the plant that absorbs the most light, unlike roots and stems.

Which will absorb the most light?

• plant with many leaves

• plant with few leaves

Answer explanation

A plant with many leaves has a larger surface area to capture sunlight, allowing it to absorb more light for photosynthesis compared to a plant with few leaves.

What organelle allows plants to do the process of photosynthesis? _________ What part do roots play in the process of photosynthesis? _________.

• chloroplasts, absorb water and nutrients
• Mitochondria, converts sunlight to usable energy

Answer explanation

The organelle that allows plants to perform photosynthesis is the chloroplasts, which contain chlorophyll for capturing sunlight. Roots play a crucial role by absorbing water and nutrients necessary for the photosynthesis process.
