What two layers of the plant contain chloroplast?

Palisade layer and Spongy Layer

The outermost layer of cells:

Epidermis

The waxy covering of the leaf:

Cuticle

These cells function to open and close stomata.

Guard cells

Outer layer of the vein:

Bundle sheath cells

Column like cells that lie just under the epidermis.

Palisade

Opening that allow for gas exchange.

Stomata

The stalk that connects the leaf to the stem.

Petiole

What’s A and what is its function

Pollen, to contain the male gametes (sperm) of the flower.

What’s B and what’s its function

Pollen tube, allows pollen to go down through the style and reach the ovules.

What’s C and what’s its function

Petal, attracts pollinators to the flower

What’s D and what’s its function?

Sepal, protects maturing flower bud

What’s E and what’s its function?

Receptacle, cup like structure that holds the flower

What’s F and what’s its function?

Pedicure, supports the flower

What’s G and what’s its function?

Ovule, holds the female gamete (egg)

What’s H and what’s its function?

Ovary, holds the ovule
