Explain the observations about survival of plant species through written or verbal forms, sketches, ICT in a creative way
Survival of Plant Species
Plants have special characteristics for survival and protection from the enemies. These special features also help plants to adapt to the climate of their surroundings.
4.1
Survival of Plant Species
Plants have special characteristics to maintain the survival of their species in two situations:
Protect themselves from the enemies
Adaptation to climate and seasonal changes
Protection from the enemies
The special features of plants for protection are:
sharp thorns
fine hairs
produce latex
poisonous
release stench
Special characteristic
Description
Example
Sharp thorns
Its sharp thorns will injure animals that try to eat it
Durian
Cactus
Fine hairs
Fine hairs cause itchiness to the enemy
Bamboo
Sugarcane
Produce latex
The sticky latex avoids animals from eating it
Jackfruit
Papaya
Poisonous
Poison causes his enemies to get sick or die when eaten
Pong-pong
Mushroom
Release stench
Emits an unpleasant odor to prevent animals from eating it
Rafflesia
Lantana camara
Adaptation to climate and season
The special characteristics of plants to adapt to climate and seasonal changes are:
Flexible stems
Pinnacle leaves
Needle-shaped leaves
Thorns
Water storing stem
Long roots
Fine hairs
Folding of leaves
Waxy leaves
Shedding of leaves
Thick skins
During high wind season:
Flexible stems
and
pinnacle leaves on coconut trees
can reduce wind resistance
Flexible stems and twigs
as well as
needle-shaped leaves
prevent it from toppling down during strong wind for ru trees
During summer and dry seasons:
Leaves that are modified into
thorns
on a cactus prevent it from losing water. Its
stems that can store water
and its
long roots
can move deep into the soil to absorb water
The
fine hairy stems and leaves
on tomato plants can prevent them from losing water during hot weather
The turmeric tree
fold its leaves
during hot weather to prevent water loss
The yam tree has
waxy leaves
to prevent too much water loss
Rubber trees
shed their leaves
during hot weather and dry seasons to avoid excessive water loss
Cold climate:
Maple trees have
thick bark
on the trunk to protect themselves in cold climates
Pine trees have
needle-shaped leaves
and
thick bark
to survive in cold climates.
The thick bark on the stems of plants can protect the water absorbed by the plants from freezing due to extreme cold climates.
