Adaptations of Plant leaves

Question 1

Large Surface Area (Leaf)

Answer 1

-Increased surface area for the diffusion of Carbon Dioxide
-Absorption of light for photosynthesis

Question 2

Thin

Answer 2

-Carbon dioxide diffuses into the Palisade Mesophyll Cells quicker

Question 3

Chlorophyll

Answer 3

-Absorbs light energy so photosynthesis can take place

Question 4

Network of veins

Answer 4

-Transport of water to the cells of the leaf
-Carbohydrates from the leaf for photosynthesis

Question 5

Stomata

Answer 5

_Allows Carbon Dioxide to diffuse into the leaf
-Allows Oxygen to diffuse out

Question 6

Epidermis is thin and transparent

Answer 6

-More light reaches palisade cells

Question 7

Thin cuticle made of wax

Answer 7

Protects the leaf without blocking sunlight

Question 8

Palisade cell layer at top of the leaf

Answer 8

-Maximises the absorption of light
-Light will hit the chloroplasts directly

Question 9

Spongy Layer

Answer 9

• Contains internal air spaces
  -Increasing surface area for diffusion

Question 10

Vascular Bundles

Answer 10

Thick cell walls in the bundles help support the stem and leaf
