Characteristics of Halophyte plants Flashcards
1
Q
Where can we find halophyte plants?
A
- high salt concentration water areas
- low oxygen content
2
Q
What are the characteristics of halophyte plants leaves?
A
- succulent leaves
- embedded stomata and thick leaves
- Hydatodes
- old leaves store high content of salt and will fall off if salt content is too high
3
Q
Does the stomata of halophyte plants conduct transpiration? How do plants remove excess water?
A
- No. Because stomata are embedded in the leaves
- Remove water through hydatodes.
4
Q
What is the function of succulent leaves?
A
- to store water
5
Q
Function of hydatodes?
A
- to eliminate excessive water and salt in plant
- by forming crystals on leaves
6
Q
What are the characteristics of roots?
A
- Are brunched out widely
- pneumatophores (projecting out of roots)
- Roots have lenticels( small pores)
- Cell sap has higher salt content compared to sea water.
7
Q
Why do halophyte plants have widely brunch roots?
A
- to anchor and be stable in soft and muddy land
- to prevent being uprooted by strong wind
8
Q
What is pneumatophore roots?
A
- grow vertically upwards from soil
- known as breathing roots
9
Q
Function of lenticels.
A
- small pores located at the roots
- for gas exchange
10
Q
Why does cell sap have higher salt concentration than salt water?
A
- allow water diffuses in from surroundings to cell through osmosis.
