Photosynthesis and plant nutrition

Question 1

Stomata

Answer 1

Allows carbon dioxide to diffuse into the leaf and oxygen to diffuse out. They’re little holes on the underside of the leaf

Question 2

Waxy cuticle

Answer 2

Protects the leaf from infection and prevents water loss without blocking out light

Question 3

Xylem

Answer 3

Transports water and minerals

Question 4

Upper epidermis

Answer 4

Allows light to get to the palisade cells

Question 5

Guard cells

Answer 5

They open and close the stomata to allow gas exchange

Question 6

Chloroplasts

Answer 6

Chlorophyll in the chloroplasts have the pigment that makes the leaf look green and they carry out photosynthesis

Question 7

Lower epidermis

Answer 7

It’s a protective layer

Question 8

Spongy layer

Answer 8

Allows air space

Question 9

Phloem

Answer 9

Transports sugar

Question 10

Palisade layer

Answer 10

Absorbs more light and increases rate of photosynthesis

Question 11

What is the word equation for photosynthesis?

Answer 11

Carbon dioxide + water —> glucose + oxygen

Question 12

What is the balanced symbol equation for photosynthesis?

Answer 12

6CO2 + 6H2O —> C6H12O6 + 6O2
