SEED GERMINATION

Question 1

thread of life, assures survival of plant species, key to modern agriculture, essential for crop crop production

Answer 1

seed germination

Question 2

first stage in the life cycle of plants

Answer 2

seed

Question 3

protected inside the testa, baby plant

Answer 3

embryo

Question 4

food which fuels seed growth is packed

Answer 4

cotyledon

Question 5

first rudimentary root that has the embryo

Answer 5

radicular/radicle

Question 6

bud that is the opposite side to the radicle

Answer 6

plumule

Question 7

first or first two leaves of the embryo of a flowering plant

Answer 7

cotyledon

Question 8

becomes the stem, space between radicle and epicotyl

Answer 8

hypocotyl

Question 9

will become the shoot

Answer 9

epicotyl

Question 10

phases of seed germination

Answer 10

activation of embryo
elongation
emergence of radicle

Question 11

Seed germination is a mechanism, in which morphological and physiological alterations result in the activation of the embryo

Answer 11

activation of embryo

Question 12

Before germination, seed absorbs water, resulting in the expansion and elongation of seed embryo

Answer 12

elongation

Question 13

When the radicle has grown out of the covering seed layers, the process of seed germination is completed

Answer 13

emergence of radicle

Question 14

seedling growth after radicle emergence

Answer 14

seedling establishment

Question 15

rapid mobilization of stored food reserves

Answer 15

post germination process

Question 16

requirements for germination

Answer 16

gases
temperature
water

Question 17

characteristic of bean and pine seeds, more primitive than hypogeal
cotyledons are raised above ground

Answer 17

epigeal germination

Question 18

cotyledons remain beneath the soil
characteristic of pea plants

Answer 18

hypogeal germination

Question 19

defined as a factor that elicits germination such as light, temperature, and moisture

Answer 19

trigger agents

Question 20

factors that must be present in seed germination

Answer 20

germination agent

Question 21

patterns of seed germination

Answer 21

phase I: imbibition
phase II: lag phase
phase III: mobilization of reserve food

Question 22

imbibition is dependent on three factors

Answer 22

composition of the seed
seed coat permeability
water availability

Question 23

important stored resources

Answer 23

carbohydrates, proteins, lipids
