Photosynthesis and Leaf Structure Flashcard

Front

What is photosynthesis?

Back

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

Front

What are the main structures involved in photosynthesis?

Back

The main structures involved in photosynthesis are chloroplasts, mesophyll cells, and stomata.

Front

What is the role of chlorophyll in photosynthesis?

Back

Chlorophyll is a pigment found in chloroplasts that absorbs light energy, primarily from the sun, which is essential for the photosynthesis process.

Front

What is the function of mesophyll in leaves?

Back

Mesophyll is the tissue in leaves where most of the photosynthesis occurs, containing chloroplasts that capture light energy.

Front

What is the role of the epidermis in plant leaves?

Back

The epidermis serves as a protective barrier for the leaf, preventing water loss and protecting against pathogens.

Front

What is the difference between the upper and lower epidermis?

Back

The upper epidermis is typically thicker and may have a waxy cuticle to reduce water loss, while the lower epidermis contains stomata for gas exchange.

Front

What are stomata and their function?

Back

Stomata are small openings on the surface of leaves that allow for gas exchange, enabling the intake of carbon dioxide and the release of oxygen.

Front

What is the significance of veins in leaves?

Back

Veins are responsible for transporting water, nutrients, and sugars throughout the plant, connecting the leaves to the rest of the plant.

Front

What is transpiration and its importance in plants?

Back

Transpiration is the process of water vapor loss from plant leaves, which helps in nutrient transport and cooling the plant.

Front

How does light intensity affect the rate of photosynthesis?

Back

Increased light intensity generally increases the rate of photosynthesis up to a certain point, after which other factors may limit the process.
