Cell walls and Chloroplasts.

Question 17

Dicots has what type of root?

Answer 17

Tap Roots

Question 18

Monocots have what type of root system?

Answer 18

Fibrous Roots

Question 19

Mitosis

Answer 19

The process of Cell Division and occurs is specific areas called Meristems (located at the crown).

Question 20

Bulliform Cells

Answer 20

bulliform cells….These cells are bubble shaped, water-filled and control leaf rolling and unrolling. Under drought conditions, bulliform cells collapse and the leaf rolls up.

Question 21

Meristems

Answer 21

Where Mitosis occurs. (At the crown)

Answer 22

Only an increase in length.

Question 23

Secondary growth means…..

Answer 23

an increase in both length and diameter.

Question 24

Mitosis vs Meiosis

Answer 24

Cell Division vs Sexual Reproduction

Question 35

Define Chloroplasts:

Answer 35

contain Chlorophil, are a vital component for photosynthesis, make those cells turn green

Question 36

Define Mitochondria:

Answer 36

responsible for Respiration.

Question 37

What are the limiting factors for Photosynthesis?

Answer 37

CO2, Sunlight and H20

Question 38

What is the Photosynthesis formula?

Answer 38

CO2 + H2O (add Sunlight and Chlorophil) = C6H12O6+O2 ``` C6H12O6 = Food or Sugar O2= By Product ```
