Monocots vs. Dicots Monocot seeds include grasses, such as corn and rye, and grains such as wheat and rice. A monocot seed contains one cotyledon, or seed.

Roots of Monocots have fibrous roots, which spread out in all directions. Dicots have “taproots”, one main root.

Kingdom: Plants Notes on Seeds!

Phylum Vascular Angiosperms Network of veins What are these?! Xylem carries water___(up or down?) Phloem carries down food

Important Prefixes Epi Hypo Means up Hypo Means down That’s right: Scientists still use Greek all the time!

Seeds Made up of three main parts! 1) Embryo (tiny plant) A. Consists of Radicle Another word for roots First part of the seed to emerge during germination

3 Parts of Embryo B. Hypocotyl Found above the radicle The stem Found above the radicle In some plants, this becomes enlarged as a storage organ

Seeds C. Epicotyl The leaf In monocot plants, the first thing to appear coming out of the ground is the epicotyl

Main Parts of Seeds Cotyledon Food supply for the embryo Until the embryo can produce food for itself through roots and leaves Depends on the size of the seed Larger seeds have food supply that can last 2 weeks!

Main Parts of Seeds Seed Coat Protective Coat The tiny plant is called an embryo because it cannot survive on its own!

Germination When the seed starts to grow! Depends on: Moisture levels Gases Temperature. Some seeds lie dormant for many years!

Monocotyledon (Monocot) Types of Seeds Monocotyledon (Monocot) Dicotyledon (Dicot)

Monocotyledon-(Monocot) A seed with one seed leaf (cotyledon Does not naturally break into two parts Examples: Lilies Onions Garlic Grass Corn Rice Oats Barley

Monocots Characteristics On the flowers, the stamen and petals come in multiples of 3’s. Leaves have parallel veins Vascular tissue (Xylem and Phloem) are spread evenly throughout the stem.

Monocot Seed! Draw the diagram and look at your previous notes to fill in the missing labels! ______________.

Dicotyledon-(Dicot) A seed with two seed leaves Naturally breaks into two parts 190,000 of the 260,000 species of plants are dicots! Examples: peas, beans, peanuts, apples, tomatoes, potato

Dicots Characteristics Flowers Leaves Stem Stamen and petals are in multiples of 4 or 5. Leaves Have branching veins Stem Vascular tissue grows on the outside ring. Trees making a ring!
