Photosynthesis and Leaf Structure

Front

What is photosynthesis?

Back

Photosynthesis is the process by which green plants, algae, and some bacteria convert light energy, usually from the sun, into chemical energy in the form of glucose, using carbon dioxide and water.

Front

What is the function of the cuticle on a leaf?

Back

The cuticle is a waxy layer that covers the surface of leaves, helping to prevent water loss through evaporation.

Front

Which part of the plant primarily absorbs sunlight?

Back

Leaves are the primary site for sunlight absorption in plants, facilitating photosynthesis.

Front

What three essential elements do plants need to grow?

Back

Plants need water, air, and sunlight to grow effectively.

Front

What gases enter and exit plants during photosynthesis?

Back

During photosynthesis, plants take in carbon dioxide and release oxygen.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a green pigment found in the chloroplasts of plants that absorbs light energy, primarily from the sun, to drive the photosynthesis process.

Front

What are chloroplasts?

Back

Chloroplasts are organelles found in plant cells that contain chlorophyll and are the site of photosynthesis.

Front

What is the equation for photosynthesis?

Back

The simplified equation for photosynthesis is: 6CO2 + 6H2O + light energy → C6H12O6 + 6O2.

Front

What is the importance of photosynthesis to life on Earth?

Back

Photosynthesis is crucial as it produces oxygen, which is essential for the survival of most living organisms, and it forms the base of the food chain.

Front

What is the epidermis in the context of leaf structure?

Back

The epidermis is the outer layer of cells on a leaf that provides protection and helps reduce water loss.
