Botany Ch. 2 - Seeds
Question | Answer |
---|---|
The part inside a seed that develops into a plant. | embryo |
The baby plant begins to grow into a little plant | seedling |
The scar on a seed or belly button | hilum |
The first true leaves of a plant. This word means "feather." | plumule |
The embryo's root | radicle |
The biggest part of the embryo that provide food for the embryo once the seed opens and embryo starts growing into a plant | cotyledons |
The plant is asleep | dormant |
The process by which a seed starts to grow into a new plant. | germination |
Food for the embryo | endosperm |
The part of the embryo that will become the stem. | hypocotyl |
Living things that must eat other lliving things to survive. | consumers |
Living things that produce their own food. | producers |
The tip of the embryo, which holds the plumule. | epicotyl |
The outer covering of a seed; its coat. | testa |
Diagram of the seed anatomy: epicotyl, plumule, hypocotyl, radicle, cotyledons | page 24 in book |
Germination process in order | radicle pushes out of the seed; radicle develops into the root; hypocotyl develops into the stem; testa comes off; cotyledons supply food to developing plant and become the seed leaves; plumule forms the first true leaves |
What type of food does the endosperm have in it? | sugar |
What does a seed need to germinate? | warmth, air, and water |
Angiosperms with one cotyledon | monocotyledons |
Angiosperms with two cotyledons | dicotyledons |
Mono means | one |
Di means | two |
Carbohydrates in the endosperm are in this form | starch |
Starch is | white, odorless, and tasteless |
Apples as they ripen, transfer starch into | sugar or glucose |
The presence of starch will cause a chemical reaction with | iodine |
The chemical reaction from the iodine causes the substance to turn what color | black (will accept dark blue since book states this) |
How does the testa come off for germination? | When water is absorbed, it loosens to let the water into the seed |
When you guess whether or not your seeds will germinate, this is called what? | hypothesis |
Plumule is the Latin word for | feather |
Beans have this very important nutrient that we must have to stay healthy | Protein |
This holds the plumule | epicotyl |
