Seeds

Question 1

seed function

Answer 1

mature, repened fertilized ovule

prod new gen of plants

Question 2

3 primary structures of seed

Answer 2

seed coat, endosperm, and embryo

Question 3

seed coat function

Answer 3

protect baby embryo and endosperm

ability to regulate when seed will sprout

Question 4

where does seed coat come from

Answer 4

integument cells that surround the ovules

Question 5

endisperm function

Answer 5

food supply

Question 6

where does endosperm come from

Answer 6

central cell of female ovule that had 2 nuclei that fused together with second sperm from the male pollen grain

double ferilization

Question 7

embryo

Answer 7

baby plant

Question 8

embryo function

Answer 8

will consume endisperma nd give rise to cotyledons

Question 9

cotyledons

Answer 9

embryonic leaves, first to emerge from seed

Question 10

do cotyledons develop in or out of seed embryo

Answer 10

in

Question 11

dicot cotyledons

Answer 11

consume endosperm
give rise to 2 cotyledons
fully formed have little to no endisperm left

Question 12

monocot cotyledons

Answer 12

only one cotyledon produced
fully formed has lrg amt of endosperm

Question 13

what does the embryo produce in dicot

Answer 13

2 cotyledons
epicotyl
hypocotyl
radicle

Question 14

epicotyl

Answer 14

embryonic shoot located above cotyledons

Question 15

what does epicotyl produce after germination

Answer 15

leaves and stems

Question 16

what will epicotyl give rise to after germination

Answer 16

apical meristem

Question 17

hypocotyl

Answer 17

embryonic stem below cotyledons

connects cotyledon and radicle

Question 18

radicle

Answer 18

embryonic root

Question 19

what does the radicle give rise to

Answer 19

the primary root of dicot

Question 20

differences between monocots and dicot seeds

Answer 20

1. dicot less endisperm
2. 2 cotyledons in dicot seeds
3. monocot seed still has hypocotyl, epicotyl, and radicle
4. monocots have coleoptle and coleorhiza

Question 21

coleoptile

Answer 21

outermost sheath of tissue surrounding the epicotyl

Question 22

coleorhiza

Answer 22

outermost sheath tissue surrounding the hypocotyl and radicle that protects them during germination
