Photosynthesis Practice Quiz

Green pigment in the chloroplast of the plant that absorbs sunlight.

• Carbon Dioxide

• Stomata

• Chlorophyll

• Glucose

Answer explanation

Chlorophyll is the green pigment found in chloroplasts that absorbs sunlight, enabling photosynthesis. It is essential for converting light energy into chemical energy, making it the correct answer.

Organelle found in plants where photosynthesis takes place.

• Chloroplast

• Stomata

• Nucleus

• Leaves

Answer explanation

The chloroplast is the organelle in plant cells where photosynthesis occurs, converting sunlight into energy. Stomata are openings for gas exchange, the nucleus contains genetic material, and leaves are structures that contain chloroplasts.

Choose all of the options that are a product of photosynthesis.

• Oxygen

• Water

• Carbon Dioxide

• Glucose

Answer explanation

Photosynthesis produces glucose and oxygen as byproducts. Water and carbon dioxide are reactants in the process, not products. Therefore, the correct answers are oxygen and glucose.

Gas that is a reactant of photosynthesis

• Glucose

• Water

• Oxygen

• Carbon Dioxide

Answer explanation

Carbon Dioxide is a key reactant in photosynthesis, where plants convert it, along with water and sunlight, into glucose and oxygen. The other options are products or components, not reactants.

Broad, flat structures that absorb sunlight and are the site of photosynthesis in plants

• Leaves

• Roots

• Stem

• Flower

Answer explanation

Leaves are broad, flat structures that absorb sunlight and are the primary site of photosynthesis in plants, making them essential for converting light energy into chemical energy.

Energy from the sun that is converted to chemical energy during photosynthesis

• Light Energy

• Kinetic Energy

• Heat energy

• Sound Energy

Answer explanation

During photosynthesis, plants convert light energy from the sun into chemical energy in the form of glucose. This process is essential for plant growth and energy storage, making light energy the correct choice.

tiny holes in the leaves of a plant where gases like carbon dioxide and oxygen enter and exit

• Chloroplast

• Stomats

• Stem

• Root

Answer explanation

The tiny holes in the leaves of a plant that allow gases like carbon dioxide and oxygen to enter and exit are called stomata. They play a crucial role in photosynthesis and respiration, making 'stomats' the correct answer.

the process plants use to convert light energy to chemical energy stored in a glucose (sugar) molecule

• Breathing

• Anaerobic Respiration

• Photosynthesis

• Aerobic Respiration

Answer explanation

Photosynthesis is the process by which plants convert light energy into chemical energy, specifically in the form of glucose. This distinguishes it from respiration processes, which involve energy release.

What is the the equation of? carbon dioxide + water --> glucose and oxygen

• Gas Exchange

• Photosynthesis

• Anaerobic Respiration

• Aerobic Respiration

Answer explanation

The equation represents photosynthesis, where carbon dioxide and water are converted into glucose and oxygen using sunlight. This process is essential for plants to produce energy and release oxygen into the atmosphere.

the type of sugar made during photosynthesis; stores energy and is used by plants and animals as "food"

• Stomata

• Chloroplast

• Carbon Dioxide

• Glucose

Answer explanation

Glucose is the type of sugar produced during photosynthesis. It serves as a primary energy source for plants and animals, making it essential for their growth and metabolism.
