HB Leaf Anatomy & ATP Review

Front

What is the spongy mesophyll?

Back

The spongy mesophyll is a layer of irregularly shaped cells in a leaf that contains air spaces, allowing for gas exchange and facilitating photosynthesis.

Front

What is the function of epidermal cells in leaves?

Back

Epidermal cells form the outermost layer of a leaf, providing protection from external elements and preventing water loss.

Front

What are the components of an ADP molecule?

Back

ADP (Adenosine Diphosphate) is composed of adenine, ribose, and two phosphate groups.

Front

How is ADP similar to a battery?

Back

ADP can be compared to a battery in need of recharging because it has low energy and can be converted to ATP (Adenosine Triphosphate) through the addition of a phosphate group.

Front

What is ATP and its role in cells?

Back

ATP (Adenosine Triphosphate) is a high-energy molecule that serves as the primary energy carrier in cells, powering various biological processes.

Front

What is the role of palisade cells in leaves?

Back

Palisade cells are tightly packed cells located beneath the upper epidermis of leaves, containing chloroplasts for photosynthesis.

Front

What is the waxy cuticle?

Back

The waxy cuticle is a protective layer on the surface of leaves that reduces water loss and protects against environmental damage.

Front

What is the difference between ADP and ATP?

Back

ADP has two phosphate groups and is lower in energy, while ATP has three phosphate groups and is a high-energy molecule.

Front

What is the primary function of phloem in plants?

Back

Phloem is responsible for transporting sugars and nutrients produced during photosynthesis from the leaves to other parts of the plant.

Front

What is the primary function of xylem in plants?

Back

Xylem is responsible for transporting water and minerals from the roots to the rest of the plant.
