Plants Have Basic Needs
Air Sunlight Water
With water : - grow healthy - grow well - not wilted
Without water: - wilted - turn yellow - die

The Basic Needs of Human and Animals
One evening, when Cik Ti crawled out from its
shelter to search for food, the day started to rain heavily. Cik Ti immediately
crawled back to the shelter, a hole near a woody house. Cik Ti was tired.
She also felt hungry. She tried to find some food but there was no food left in
the hole. “ Oh no… I will die without food.” Said Cik Ti frustrated. Cil Ti
moved into the kitchen in that woody house. “ Arghh…… I am hungry!. Cik Ti
screamed. “Wow, cheese…. Emmm…. Delicious.” After she had her food, she
was thirsty. She saw a cup of water on the table. Cik Ti drank the water.
Tap! Tap! Tap! Without her knowing, Mamat was ready to trap her into a
plastic bag. He tighten the bag tightly. Help! Help! I can’t breath……
where is the air.” Shouted Cik Ti ….. Her voice slow down time by time.
Lastly Cik Ti dead without air…..

NATURAL DEFENSE IN PLANTS
I have sharp thorns.Don’t come near me.
I am sensitive. I will fold my leaflets. Please don’t touch me
I have latex.I will stick on you.
ADAPTION TO NATURE
My fine hairs will cause itchiness.Don’t come near me. I will make you itchy.
Unit 3/Lesson 4Natural Defense Of Plants
Cactus, how do you get water in this dry region?
My thick stem can store more water for me.
INVESTIGATING LIVING THINGS YEAR 4
I have long roots.So I can go deep in the soil to get water.
I have needle shaped leaves.So I lost less water.
Coconut tree, how do you survive from strong wind?
Oh, I have strong buttress roots.It is easy for me to defend from strong wind.
My leaves are divided so that they do not break easily.The trunk help them sway with the wind.
