Plant growth

Question 1

Plant growth results from

Answer 1

• cell division
• assimilation
• cell expansion / enlargements / elongation

Question 2

what is cell division?

Answer 2

cell division results in an increase in the number of cells

Question 3

what is cell elongation?

Answer 3

the lengthening of cell. the cytoplasm grows and the vacuole fills with water, which exerts pressure on the cell wall and causes it to expand.

Question 4

another process involved in plant growth?

Answer 4

cell differentiation

Question 5

Where apical meristems located?

Answer 5

• shoot buds

- root tips

Question 6

how germination process happen?

Answer 6

• the radicle grows downwards

- the plumule upwards

Question 7

what is the two types of germination

Answer 7

1. Hypogeal

2. Epigeal

Question 8

difference between hypogeal and epigeal

Answer 8

the cotyledons of the seed remain underground as the shoot develops (Hypogeal) while the cotyledons are carried above ground during germination, and become the first photosynthetic leaves (epigeal)

Question 9

which type of germination that the cotyledons are carried above the ground?

Answer 9

epigeal

Question 10

seed germination depends upon?

Answer 10

• temperature
• soil moisture
• oxygen levels

a. gymnosperms
b. algae
c. all plants
d. woody dicots

Answer 15

a and d

Question 16
