2.20 Flashcard: Leaves and Photosynthesis

Front

What is the cuticle in a leaf?

Back

The cuticle is a waxy layer on the surface of leaves that helps prevent water loss.

Front

Where are most chloroplasts found in a leaf?

Back

Most chloroplasts are found in the palisade mesophyll layer, which is located just beneath the upper epidermis.

Front

What is the primary function of chloroplasts?

Back

Chloroplasts are organelles in plant cells that convert sunlight into energy through photosynthesis.

Front

Define photosynthesis.

Back

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

Front

What role does chlorophyll play in photosynthesis?

Back

Chlorophyll is the green pigment in plants that captures light energy for photosynthesis.

Front

What is the upper epidermis of a leaf?

Back

The upper epidermis is the outer layer of cells on the top side of a leaf that protects it and helps reduce water loss.

Front

What is the function of the lower epidermis?

Back

The lower epidermis contains stomata, which are openings that allow for gas exchange (CO2 in, O2 out) and transpiration.

Front

What are stomata?

Back

Stomata are small openings on the surface of leaves that regulate gas exchange and water loss.

Front

What is the palisade mesophyll?

Back

The palisade mesophyll is a layer of tightly packed cells in a leaf that contains chloroplasts and is the primary site of photosynthesis.

Front

What is the process of cellular respiration?

Back

Cellular respiration is the process by which cells convert glucose and oxygen into energy, carbon dioxide, and water.
