Anatomy of the Leaf: Read the following passage about the parts of a leaf. Color the cross section of theleaf. Answer the questions about the passage.

The leaf is the primary photosynthetic organ of the plant. The outer surface of the leaf has a thin waxycovering called the cuticle (A), this layer's primary function is to prevent water loss within the leaf. Colorthe cuticle light green. Directly underneath the cuticle is a layer of cells called the epMermis (B). Color theepidermis yellow. The vascular tissue, xylem (G), which transports water, and phloem (H), whichtransports sugar, are found within the veins of the leaf. Veins are actually extensions that run from the tipsof the roots all the way up to the edges of the leaves. The outer layer of the vein is made of ceils called thebundle sheath cells (E), and they create a circle around the xylem and the phloem. Color the bundle sheathcells dark blue, the xylem orange, and the phloem purple.

A

B

Within the leaf, there is a layerof cells called the mesophyll (D& F). The word mesophyll isgreek and means "middle leaP'.Air spaces in the mesophyllallow for gas exchange. Themesophyll cells are packed withchloroplasts, and this is wherephotosynthesis actually occurs.Color the mesophyll dark green.

F

The leaf also has tiny holeswithin the epidermis, calledstomata, which allows theexchange of gas. Specializedceils, called guard cells (C)surround the stomata and areshaped like two cupped hands.Changes within water pressurecause the stoma (singular ofstomata) to open or close. Ifthe guard ceils are full of water,they swell up and bend awayfrom each other which opensthe stoma. During dry times,the guard cells close. Color theguard ceils pink.

Anatomy of the Flower: Read the following passage, label the parts of the flower using the bold wordsfrom the passage, and answer the following questions about the structure and function of the flower.

Flowers are the reproductive structures of angiosperms. Flowers are usually both male and female, and arebrightly colored to attract insects to help them carry pollen used for sexual reproduction. Nyl flowers are ,.,ÿc°l°rful' th°ugh" These fl°wers usually use the wqmd f°r p°llinati°n" ÿffÿ(_" t]

• The receptacle is the part of the branch on which a ' ÿ

flower forms. Color the receptacle brown. Sepals are , i ÿ gvtÿleaf-like structures that surround and protect the flower pt!ÿ'ÿ ÿ o ÿt'I ÿebefore it blooms. Color the sepals green. Petals are ÿC.ÿCÿ-icolorful parts of the flower that attract insects and evenother small animals, such as mice, birds, and bats.Color the petals a bright color of your choice. Allangiosperms have flowers, but some are not brightlycolored. The petals of these flowers are reduced orabsent and the plant relies on the wind or water forpollination.

The flower has both male and female reproductiveparts. The female reproductive structures arecollectively called the pistil. Color the pistil pink.The pistil has 3 parts. The stigma at the top is oftensticky and is where the pollen attaches. The style isthe long tube that attaches the stigma to the ovary. Theovary houses the ovules or eggs.

The male reproductive structures are called the stamens. Each stamen consists of an anther, whichproduces pollen, and a filament, which supports the anther. Color the anther yellow and leave the filamentwhite. Pollen produced by the anther is carried by insects or other animals to the pistil of another flowerwhere it may fertilize the eggs.

Sexual reproduction in plants occurs when the pollen (sperm) from an anther is transferred to the stigma.Plants can fertilize themselves. Self-fertilization occurs when the pollen from an anther fertilizes the eggson the same flower. Cross-fertilization occurs when the pollen is transferred to the stigma of an entirelydifferent plant.

When the ovules are fertilized, they will develop into seeds. The petals of the flower fall off leaving onlythe ovary behind, which will develop into seeds. The petals of the flower fall off leaving only the ovarybehind, which will develop into a fruit. A fruit is any structure that encloses and protects a seed. This couldbe oranges, apples, acorns, or eveÿ-'ÿuts. When you eat a fruit, you are actually eating the ovary of the

flower.
