16
Q

is a tiny plant that has a root, a stem, and one or more leaves

A

embryo

17
Q

is the nutritive tissue of the seed, often a combination of starch, oil, and protein.

A

endosperm

18
Q

an embryonic leaf in seed-bearing plants, one or more of which are the first leaves to appear from a germinating seed.

A

cotyledon

19
Q

outer covering of a seed
help protect the embryo from injury and also from drying out

A

seed coat

20
Q

the shoot or bud of a plant embryo or seedling that is located between the cotyledons and grows into the stem and leaves.

A

plumule

21
Q

tissue that surrounds and nourishes the embryo in the seeds of angiosperms (flowering plants). In some seeds the endosperm is completely absorbed at maturity (dicots)

A

endosperm

22
Q

a protective layer of tissue that surrounds the radicle (the embryonic primary root) in monocotyledon seeds

A

coleorhiza

23
Q

pointed protective sheath covering the emerging shoot in monocotyledons such as grasses in which few leaf primordia and shoot apex of monocot embryo remain enclosed.

A

Coleoptile

24
Q

scar on seed that controls the content of water in seeds during the last phase of the formation of seeds

only in dicots

A

hilum

25
Q

helps to absorb water at the time of germination of the seed. It is where the root emerges at the time of germination of the seed.

only in dicots

A

micropyle

26
Q

dicot Germination other term

A

Epigeal Germination

27
Q

monocot Germination other term

A

Hypogeal Germination
