Notes on Seeds!

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

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

4. 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

5. 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

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

7. 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!

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

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

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

11. 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

12. 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.

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

14. 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

15. 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!
