what is the cell elongation

Answer 9

cells lengthen by as much as 10 times

Question 10

what is zone differentiation

Answer 10

cells differentiate into dermal, vascular, and ground tissues

Question 11

What is the purpose of the root cap?

stems and roots

Question 13

When does the second growth occur?

Answer 13

lateral meristems

Question 14

What are lateral meristems?

Answer 14

areas of active cell division that exists in two cylinders that extend along the length of roots and shoots

Question 15

What is the vascular cambium?

Answer 15

lateral meristems that lie between primary xylem and primary phloem

Question 16

What is the cork cambium

Answer 16

lateral meristem that lies at the outer edge of stem cortex

Secondary xylem
secondary phloem

What does the secondary xylem produce

Answer 19

wood towards the interior of stem

Question 20

what does the secondary phloem produce?

Answer 20

inner bark towards the exterior of the stem

Question 21

What direction of cork cambium produce in?

Answer 21

one directiion

Question 22

What is outer bark composed of?

Answer 22

cork cells

Question 23

What do wood annual rings show?

Answer 23

layers of secondary xylem

Question 24

What does the embryonic development produce?

Answer 24

a mature seed

Question 25

What is seed dormancy?

Answer 25

A period of time when the embryonic growth and development is suspended

Question 26

What does seed dormancy allow for?

Answer 26

germination when conditions are favorable

Question 27

How many cotyledons do Eudicot (dicot) seeds have?

Answer 27

two cotyledons

Question 28

What do Eudicot seeds have that lack protective sheaths?

Answer 28

apical meristems

Question 29

Why do Eudicot have no endosperm?

Answer 29

the fleshy cotyledons absorbed the endosperm nutrients as the seed formed

Question 30

Answer 30

one cotyledon

Question 31

What acts as a protective sheath in monocot seeds?

Answer 31

embryonic root and shoots

Question 32

True or False: Monocot seeds do have a endosperm

Answer 32

true

Question 33

What causes the fruit to develop

Answer 33

hormonal changes induced by fertilization trigger the ovary to develop the fruit

Question 34

What is the purpose of fruit?

Answer 34

house and protect seeds aid in dispersal

Question 35

What three things happen after pollination?

Answer 35

Flower drops its petals ovary starts to grow pod forms holding seeds

Question 36

What happens at germination?

Answer 36

a seed takes up water and resumes growth and development

Question 37

How does a Eudicot grow?

Answer 37

embryonic root emerges first and grows downward shoots emerge from the soil and hooks downward
