germination

Question 1

germ

Answer 1

embryo of a seed

Question 2

germination

Answer 2

the sprouting of a seed

Question 3

what is germinaiton cultivated by

Answer 3

envi cues

Question 4

germination steps

Answer 4

pre emergence
emergence

Question 5

pre emergence steps

Answer 5

water absorption
stored food digestion
cell growth
cell division

Question 6

pre emergence water abosrbion

Answer 6

seeds swell as they absorb water

also called imbibition

Question 7

pre emergence stored food digestion

Answer 7

water activates enzymes that break down stored food to support growth, and sent to places in seed

Question 8

pre emergence cell growth

Answer 8

cell enlargement with turgor pressure

Question 9

pre emergence cell division

Answer 9

mitosis from meristematic tissue

Question 10

emergence steps

Answer 10

radicle emerges
hypocotyl emerges
epicotyl growth

Question 11

emergence radicle emrges

Answer 11

root, first thing to emerge

primary root

Question 12

emergence hypocotyl emerges

Answer 12

stem

grows upwards to form elbow hinge

pulls remains of seed above surface

Question 13

emergence epicotyl growth

Answer 13

shoot

cotyledons might shed coat and contains apical meristem

Question 14

does the epicotyl have to push through the soil on its own in dicots

Answer 14

yes

Question 15

where do cotylons go in dicots

Answer 15

undergrounf

Question 16

does the hypocotyl form the elbow hinge in monocots

Answer 16

no

Question 17

what remains underground for monocots

Answer 17

cotyledon, remaining endosperm, and seed coat

Question 18

vernalization

Answer 18

prolonged period of cold necessary to induce seed germination

Question 19

photoblastic

Answer 19

seeds that have a response to light during germination

Question 20

posotively photoblastic

Answer 20

req light to germinate

both light and hormone signals involved

Question 21

hormones involved in photoblastic

Answer 21

gibberellins

Question 22

seed mucilage

Answer 22

mucilage around the seed coat that swells up when hydrated

Question 23

function of mucilage

Answer 23

facilitate water uptake
seed dispersal
maintain dormancy

Question 24

why can inhibiting seed germination be helpful

Answer 24

to prevent sprouting in fruit
