Exploring Leaf Parts

What is the main function of a leaf?

• Photosynthesis

• Water absorption

• Nutrient storage

• Support for the plant

Name the outer layer of a leaf.

• Epidermis

• Cuticle

• Mesophyll

• Stomata

What is the purpose of the stomata?

• To provide structural support to the leaves.

• To absorb sunlight for photosynthesis.

• The purpose of the stomata is to facilitate gas exchange and regulate water loss in plants.

• To store nutrients for the plant.

Which part of the leaf is responsible for photosynthesis?

• Chloroplasts in the mesophyll cells

• Stomata on the leaf surface

• Xylem vessels in the leaf

• Cuticle layer of the leaf

What is the name of the tissue that transports water in a leaf?

• xylem

• epidermis

• cortex

• phloem

Identify the part of the leaf that helps in gas exchange.

• chloroplasts

• stomata

• phloem

• xylem

What is the function of the cuticle on a leaf?

• The cuticle helps in photosynthesis by absorbing sunlight.

• The cuticle allows for gas exchange between the leaf and the atmosphere.

• The cuticle serves as a nutrient reservoir for the leaf.

• The cuticle functions to prevent water loss and protect the leaf from damage.

Which part of the leaf connects it to the stem?

• stomata

• petiole

• leaf margin

• blade

What are the tiny openings on the leaf surface called?

• Chloroplasts

• Pores

• Lenticels

• Stomata

What is the difference between a simple leaf and a compound leaf?

• A simple leaf has multiple leaf blades; a compound leaf has one leaf blade.

• A simple leaf is always larger than a compound leaf.

• A simple leaf is made up of several layers, while a compound leaf is flat.

• A simple leaf has one leaf blade; a compound leaf has multiple leaflets.
