Understanding Photosynthesis

Front

What are the 3 reactants of photosynthesis? The reactants are the things needed for photosynthesis to occur.

Back

carbon dioxide, sunlight, water

Answer explanation

Plants need three things for photosynthesis: carbon dioxide, sunlight, and water. They use these to make glucose, which is a type of sugar, and oxygen..

Front

What is the tiny openings that let in the carbon dioxide needed for photosynthesis?

Back

stomata

Answer explanation

The tiny openings that let carbon dioxide enter a plant for photosynthesis are called stomata. They are important for gas exchange. Xylem and phloem transport water and nutrients, while chloroplasts are where photosynthesis happens.

Front

What are the 2 products of photosynthesis? The products are the things made in the process of photosynthesis.

Back

oxygen, glucose

Answer explanation

Plants make two important products during photosynthesis: oxygen and glucose. In this process, they use sunlight, carbon dioxide, and water to create glucose for energy. They also release oxygen as a byproduct.

Front

What is the main purpose of photosynthesis?

Back

To make food

Answer explanation

The main purpose of photosynthesis is to make food for plants by converting sunlight, carbon dioxide, and water into glucose. While it also releases oxygen and absorbs sunlight, the primary goal is food production.

Front

How does oxygen get released by the plant? Name the structure in the leaf.

Back

stomata

Answer explanation

Plants release oxygen during photosynthesis through small openings called stomata. These openings let gas exchange happen, allowing oxygen to leave the leaf and enter the atmosphere.

Front

Which part of the plant cell (organelle) is responsible for making food (Glucose) using sunlight?

Back

Chloroplast

Answer explanation

The chloroplast is a part of plant cells that changes sunlight into energy through photosynthesis. This process creates glucose, which serves as food for plants. It is important for their growth and energy.

Front

What changes to matter and energy occur during photosynthesis?

Back

Changes that convert light energy into chemical energy stored in carbohydrates.

Answer explanation

The correct choice highlights the key process of photosynthesis, where light energy is converted into chemical energy stored in carbohydrates, which is essential for plant growth and energy storage.

Front

How does a plant obtain its energy?

Back

Energy enters the plant when sunlight is trapped by chlorophyll.

Answer explanation

Plants get energy from sunlight, which chlorophyll captures. This process is essential for photosynthesis. Other options do not correctly describe the main energy source for plants.

Front

What is the primary purpose of photosynthesis in plants?

Back

To produce glucose and oxygen

Front

How will a plant get its water for photosynthesis?

Back

From the ground by pulling it in through its roots
