Question 4

Seed coat

Answer 4

Hard structure that has the embryo and it’s food supply in it

Question 5

Hypocotyl

Answer 5

Below the cotyledons is the embryonic axis; immature stem

Question 6

Radicle

Answer 6

Where the cotyledons terminate

Question 7

Epicotyl

Answer 7

Above cotyledons; immature seed/meristems

Question 8

Coleoptile

Answer 8

Immature leaf in a monocot

Question 9

Coleorhiza

Answer 9

Early rooting function in a monocot

Question 10

List a benefit to dormancy.

Answer 10

Increase chances that germination will occur at a time and place most advantageous to plant

Question 11

Which part of the seed emerges first?

Answer 11

Radicle (embryonic root)

Question 12

Fruit

Answer 12

Develops from ovary; protects enclosed seeds and aids in seed dispersal w/ the help of wind and animals

Question 13
