SEEDS OF LIFE

WORD BANK Seed Coat- the protective layer on the outside of the seed Cotyledon- composed of endosperm that provides the plant with food as it starts to grow Dicot- seed with two cotyledons Monocot- seed with one cotyledon

WORD BANK Embryo- Baby plant Germination- process when a seed starts to grow

GERMINATION When a seed germinates, it starts to grow and develop. We saw that the seed coat wrinkles up and splits open, and we saw the cotyledons and the embryo inside. What happens next and how can we find out?

RYE GRASS AND RADISH SEEDS These seeds are very small so in order to observe each step in the germination process, we are going to sprout them on paper. A MINISPROUTER!

MINISPROUTER 1.Fold a paper towel in quarters 2.Trace the bottom (smaller half, no sticker) of the petri dish 3.Cut the circle out (this will give you 4) 4.Fold three circles in half. Put them in the petri dish top (larger diameter) 5.Cover the folded circles with an unfolded circle 6.Ask me to wet the paper towels

PLANTING SCHEDULE Each pair will make one minisprouter (1and2=radish, 3and4=rye) 6 or 7 seeds on the shelf of the dish Close the sprouter by taping the bottom of the petri dish in place over the seeds. Label the sprouter with the group number and seed type

ASSEMBLE THE MINISPROUTERS!

STORE THE MINISPROUTERS In order to simulate the conditions seeds might experience underground, I will place a cover over the seeds to make sure they are kept in the dark. We should not expose them to light except to make brief observations over the next several days.

CHANGES, Day 2 What happened to the seeds? Are there any differences between the radishes and the rye grass? What colors do you see? Describe

ENTRY ACTIVITY In your journal wherever you have space, draw a picture of a split open lima bean seed and label its three main parts.In your journal wherever you have space, draw a picture of a split open lima bean seed and label its three main parts.

SEEDLINGS Choose one of the most developed seedlings from each tray (1 radish, 1 rye) Place them on your tray

WHERE IS THE SEED NOW? Compare the two kinds of sprouts. Where is the seed now? What do we call the two halves of the seed? What is their purpose? Do you see the cotyledons anymore?

MONOCOTS AND DICOTS Remember, monocot=1 cotyledon, dicot=2 cotyledons Grasses are monocots. The cotyledon stays in the ground and nourishes the sprout. Radishes are dicots. The two cotyledons come up above the ground and change color and shape to look a lot like leaves. The two round leaflike structures on top of the radish sprouts are cotyledons.

ROOT What part of the seedling came out of the seed first? Why do you think this is?

MICROSCOPES What do you think we will see when we view the roots under microscopes?

RETURNING PETRI DISHES Seeds the size of yours might be pushing above the ground by now. We will have odd groups leave their seeds in the light and even groups put them back under the chamber with cover to see if it makes a difference.
