Intro to Photosynthesis

What would happen to plants if they couldn’t perform photosynthesis?

• They would continue growing normally

• They would stop growing and eventually die

• They would grow faster

• They would start producing more oxygen

Answer explanation

If plants cannot perform photosynthesis, they cannot produce the energy needed for growth. This would lead to stunted growth and ultimately death, as they rely on photosynthesis for sustenance.

Explain the connection between sunlight and plant growth.

• Plants use sunlight to make food through photosynthesis, which helps them grow

• Plants need sunlight to take in oxygen, which helps them grow

• Sunlight keeps plants warm so they can grow

• Sunlight helps plants move water from their roots to their leaves

Answer explanation

Plants use sunlight to perform photosynthesis, a process that converts light energy into chemical energy, allowing them to produce food. This food is essential for their growth and development.

What is glucose, and why is it important to plants?

• It is a type of sugar and it’s the plant’s food

• It is a type of water and helps plants stay cool

• It is a type of gas and helps plants make oxygen

• It is a type of light that helps plants grow

Answer explanation

Glucose is a type of sugar produced by plants during photosynthesis. It serves as their primary source of energy and is essential for growth and development, making it crucial for plant survival.

Why is photosynthesis important to animals and humans?

• It gives us carbon dioxide to breathe

• It produces food and oxygen, which we need to live

• It creates sugar that animals eat

• It removes oxygen from the air

Answer explanation

Photosynthesis is crucial because it produces food and oxygen. Animals and humans rely on oxygen for respiration and food for energy, making this process essential for our survival.
