Photosynthesis

Front

What is the pigment in chloroplasts that performs photosynthesis?

Back

Chlorophyll

Answer explanation

The pigment in chloroplasts that performs photosynthesis is chlorophyll. It captures light energy, which is essential for converting carbon dioxide and water into glucose and oxygen during the photosynthesis process.

Front

What are the products of photosynthesis?

Back

oxygen and glucose

Answer explanation

The products of photosynthesis are oxygen and glucose. During this process, plants convert carbon dioxide and water into glucose for energy, releasing oxygen as a byproduct.

Front

Which of the following go through the process of  photosynthesis? bees, algae, humans, mushrooms

Back

algae

Answer explanation

Algae are photosynthetic organisms that convert sunlight into energy, using chlorophyll. Unlike bees, humans, and mushrooms, which do not perform photosynthesis, algae play a crucial role in producing oxygen and organic matter.

Front

What is the correct equation for photosynthesis?

Back

6CO₂ + 6H₂O  -->  6O₂ + C₆H₁₂O₆

Answer explanation

The correct equation for photosynthesis is 6CO₂ + 6H₂O → 6O₂ + C₆H₁₂O₆. This shows that carbon dioxide and water are converted into glucose and oxygen, which is the fundamental process of photosynthesis.

Example of a HETEROTROPH: Grass, Algae, Lemon Tree, Bear

Back

Bear

Answer explanation

A heterotroph is an organism that cannot produce its own food and relies on consuming other organisms. Bears are heterotrophs as they eat plants and animals, while grass, algae, and lemon trees are autotrophs that produce their own food.

Front

Which organisms perform Photosynthesis?

Back

Only Autotrophs

Answer explanation

Only autotrophs, such as plants and some bacteria, can perform photosynthesis, converting sunlight into energy. Heterotrophs, like animals, rely on consuming other organisms for energy.

Front

What do plants need for the photosynthesis process?

Back

light, carbon dioxide, and water

Answer explanation

Plants need light, carbon dioxide, and water for photosynthesis. These elements are essential for converting sunlight into energy, allowing plants to produce glucose and oxygen, which are vital for their growth and survival.

Front

What are the reactants of photosynthesis?

Back

carbon dioxide and water

Answer explanation

The reactants of photosynthesis are carbon dioxide and water. During the process, plants use sunlight to convert these reactants into glucose and oxygen, making carbon dioxide and water the correct answer.

Front

The cell organelle that is the site for photosynthesis is called:

Back

chloroplast

Answer explanation

The chloroplast is the organelle responsible for photosynthesis, converting light energy into chemical energy in plants. Mitochondria are for respiration, the nucleus contains genetic material, and the cytoplasm is the fluid inside the cell.

Front

Plants give off _____ that animals need to take in; animals give off _____ that plants need to take in.

Back

oxygen; carbon dioxide

Answer explanation

Plants produce oxygen through photosynthesis, which animals need to breathe. Conversely, animals exhale carbon dioxide, which plants require for photosynthesis. Thus, the correct answer is oxygen; carbon dioxide.
