What do plants need to do photosynthesis?

Back

Sun's energy

Answer explanation

Plants need the Sun's energy to perform photosynthesis, which allows them to convert light into chemical energy. The other options do not provide the necessary energy for this process.

Front

What gas goes into the plant before photosynthesis?

Back

Carbon Dioxide

Answer explanation

The gas that enters plants before photosynthesis is Carbon Dioxide. Plants use it, along with sunlight and water, to produce glucose and oxygen during the photosynthesis process.

Front

What three things are needed for plants to perform photosynthesis?

Back

CO₂, Water, Sunlight

Answer explanation

Photosynthesis requires carbon dioxide (CO2), water, and sunlight. Plants use sunlight to convert CO2 and water into glucose and oxygen, making CO2, water, and sunlight the essential components for this process.

Front

What two products does a plant make during photosynthesis?

Back

Oxygen and Glucose

Answer explanation

During photosynthesis, plants convert carbon dioxide and water into glucose and oxygen. Therefore, the correct products made are oxygen and glucose.

Front

Which part of the plant absorbs water and nutrients?

Back

Roots

Answer explanation

The roots are the part of the plant that absorb water and nutrients from the soil. They anchor the plant and play a crucial role in its growth and health, making them essential for nutrient uptake.

Front

Which part of the plant transports water and nutrients to different parts of the plant?

Back

Stem

Answer explanation

The stem is the part of the plant that transports water and nutrients from the roots to the leaves and other parts. It acts as a support structure and is essential for the plant's overall growth and health.

Front

Which part of the plant collects the sun's energy and makes food?

Back

Leaf

Answer explanation

The leaf is the part of the plant that collects sunlight and uses it in photosynthesis to produce food for the plant. This process is essential for the plant's growth and energy.

Front

What is the name of the green pigment inside plants?

Back

Chlorophyll

Answer explanation

The green pigment in plants is called chlorophyll. It plays a crucial role in photosynthesis, allowing plants to absorb sunlight and convert it into energy. The other options listed are not recognized pigments in plants.

Front

Which of these is NOT A TRUE statement about photosynthesis?

• It captures and makes the sun's energy available to all species
• It turns deadly CO₂ into Oxygen for us to breathe
• It helps plants create energy to send to rest of food chain
• It makes the water for our planet

Back

It makes the water for our planet

Answer explanation

The statement "It makes the water for our planet" is NOT true about photosynthesis. While photosynthesis produces oxygen and glucose, it does not create water; water is a reactant in the process.

Front

Which of these is NOT AN IMPACT photosynthesis has on an ecosystem?

• Oxygen for animals and humans to breathe
• Food for us to eat
• Taking CO₂ out of the air
• Taking oxygen out of the air

Back

Taking oxygen out of the air

Answer explanation

Photosynthesis produces oxygen, which is essential for animals and humans, and removes CO₂ from the air. However, it does not take oxygen out of the air; instead, it releases oxygen, making 'Taking oxygen out of the air' the correct choice.
