Horticulture - Parts of a Leaf

Front

What is the midrib of a leaf?

Back

The midrib is the central vein of the leaf that provides support and transports nutrients and water.

Front

Where is the upper epidermis located on a leaf?

Back

The upper epidermis is the outer layer of cells on the top side of the leaf, providing protection and minimizing water loss.

Front

What is the function of the leaf margin?

Back

The leaf margin is the edge of the leaf, which can vary in shape and texture, and plays a role in water retention and gas exchange.

Front

What are palisade cells?

Back

Palisade cells are elongated cells located beneath the upper epidermis of the leaf, containing chloroplasts for photosynthesis.

Front

What is the tip of a leaf?

Back

The tip of a leaf is the pointed end, which can influence the leaf's overall shape and function.

Front

What role do chloroplasts play in leaf cells?

Back

Chloroplasts are organelles in leaf cells that carry out photosynthesis, converting sunlight into energy.

Front

What is the purpose of the lower epidermis in a leaf?

Back

The lower epidermis is the protective layer on the underside of the leaf, containing stomata for gas exchange.

Front

What are stomata?

Back

Stomata are small openings on the leaf surface that allow for the exchange of gases (CO2 and O2) and transpiration.

Front

How does the structure of a leaf aid in photosynthesis?

Back

The structure of a leaf, including its large surface area and arrangement of chloroplasts, maximizes light absorption for photosynthesis.

Front

What is the role of veins in a leaf?

Back

Veins are vascular tissues that transport water, nutrients, and sugars throughout the leaf.
