Leaf Anatomy and Functions

What is the outer protective layer of a leaf called?

• chlorophyll

• cuticle

• stoma

• epidermis

Name the tiny openings on the underside of a leaf that allow for gas exchange.

• stomata

• openings

• pores

• veins

Which part of the leaf is responsible for capturing sunlight for photosynthesis?

• Mitochondria

• Stomata

• Xylem

• Chloroplasts

What is the main function of the veins in a leaf?

• Store excess water

• Regulate temperature

• Absorb sunlight for photosynthesis

• Transport water, nutrients, and sugars; provide structural support

What type of leaf has a single blade attached to the stem?

• Double leaflet

• Compound leaf

• Complex leaf

• Simple leaf

Which part of the leaf is responsible for regulating water loss?

• Stomata

• Chloroplasts

• Xylem

• Epidermis

Describe the process of photosynthesis in leaves.

• Photosynthesis in leaves is the process by which plants convert light energy into chemical energy in the form of glucose, using chlorophyll, carbon dioxide, and water.

• Photosynthesis in leaves is the process of converting water into oxygen.

• Photosynthesis in leaves occurs in the roots of plants.

• Photosynthesis in leaves involves the breakdown of glucose into carbon dioxide.

How do leaves adapt to dry environments?

• Leaves adapt to dry environments by opening stomata wider

• Leaves adapt to dry environments by developing thinner cuticles

• Leaves adapt to dry environments by reducing surface area, developing thicker cuticles, and closing stomata.

• Leaves adapt to dry environments by increasing surface area

Identify the type of leaf that is needle-like and retains water well.

• Opposite

• Palmate

• Sclerophyllous

• Deciduous

What is the function of the stomata in a leaf?

• Gas exchange

• Water absorption

• Photosynthesis

• Nutrient transport
