Habitat 1

High altitude

2
New cards

What adaptations does this plant have?

is white, reflective, and has wooly hair

3
New cards

What is the purpose for these structures (1.1)

  • hair traps and insulates against low temperatures

  • white hair protects against high UV radiation/ The Sun

4
New cards

What adaptations does this plant have?

small leaves, stunted growth to stay low to the ground

5
New cards

What is the purpose of these structures (1.2)

  • prevents excessive transpiration

  • protects from harsh weather conditions

6
New cards

What adaptations does this plant have

thick fleshy leaves

7
New cards

What is the purpose of this structure (1.3)

helps with water conservation/during dry periods

8
New cards

Habitat 2

Sand dunes (dry)

9
New cards

What adaptations does this plant have

Marram grass

  • thick waxy cuticle

  • leaves can roll during drought

  • indented stomata

10
New cards

What is the purpose of these structures (2.1)

  • reduces water loss through

  • rolled up leaves make a humid chamber reducing exposure to

  • keep humid air no exposure to wind transpiration

11
New cards

What adaptations does this plant have

underground stems (rhizomes)

12
New cards

What is the purpose of this structure (2.2)

  • provide stability

  • can extend deep into the ground to obtain water

13
New cards

What adaptations does this plant have

accumulation of carbohydrates in root/leaf cells

14
New cards

What is the purpose of this structure (2.3)

storage for sugars = increase osmotic potential = help absorb water

15
New cards

Habitat 3

Mangrove tree (waterlogged soil)

16
New cards

What adaptations is this for the mangroves?

  • pneumatophores

  • cable roots

17
New cards

What do these roots do (3.1)

  • grow into the air and absorb oxygen

  • provide stability, grow to the ground to absorb O2

18
New cards
<p>What adaptation does this plant have</p>

What adaptation does this plant have

still roots growing in a downward arch from the stem

19
New cards

What do these roots to (3.2)

anchor the tress into the ground and increase stability

20
New cards
<p>What adaptation do these seeds have</p>

What adaptation do these seeds have

buoyant seeds

21
New cards

What is the purpose of this structure (3.3)

carried away by ocean currents and allow dispersal to fertile soil
