Specific Characteristics for plants to survive:
1. Needle-shaped leaves2. Thick Stems3. Long roots 4. Loses it leaves5. Waxy and waterproof leaves6. Leaves with fine hairs7. Leaves which curld up during sunny
1.Needle-shaped leaves
To prevent excessive loss of water Example of plants:
Cacti
2.Thick stems
Use to store water Example of plants
Cacti
3.Long roots
Long roots to grow deep into the undergroundto get waterExample of plants:Cacti
4.Loses it leaves during dry season Use to reduce the loss of water Example of plants:
Maple tree, Rubber tree
5.Waxy and waterproof leaves
Use to reduce the loss of water Example of plants
Mesquite tree, Yam plant, banana tree, pandan
6.Leaves with fine hair
Use to reduce the loss of water Example of plants
pumpkin plant, watermelon plant
7.Leaves which curl up during sunny
Use to reduce the loss of water Example of plants
banana tree, maize plant, lalang
B.STRONG WIND AREA
Specific characteristics for plants to survive:
1. Buttress roots2. Long and divided leaves3. Stem that bend easily4. Needle-shaped leaves
1.Buttress roots
Roots grow at the base of the stem Example of plants:
mangrove tree, coconut tree, rubber tree
2.Long and divided leaves
To prevent the plant from being damaged by strong winds
Example of plants:Coconut tree, betel nut palm
3.Stems that bend easily
To prevent the plants from being broken easily Example of plants:
Coconut tree, bamboo plant
4.Needle-shaped leaves
Allow a strong wind to pass through between the leaves.
Example of plants:Pine tree, casuarina tree
