The Hunger Shadows is performing a presentation about plants, flowers and other things.

Lets begin!!!

How did the plant get to the crack of the wall ?A wind blow the seed into the crack.A bird bring the seed to the crack

Q1

Why are plants so important?

Plants are the backbone of all life on Earth and an essential resource for human well-being. Just think about how your everyday life depends on plants

Food: Everything we eat comes directly or indirectly from plants. Throughout human history, approximately 7,000 different plant species have been used as food by people. 

Air: Oxygen is brought to you by plants, as a by product of photosynthesis.

Water: Plants regulate the water cycle: they help distribute and purify the planet's water. They also help move water from the soil to the atmosphere through a process called transpiration.

Climate: Plants store carbon, and have helped keep much of the carbon dioxide produced from the burning of fossil fuels out of the atmosphere.

Q3

DISPERSAL OF SEEDS

Q4

Types of seed dispersalWATER

WIND

ANIMALS

EXPLOSION

Seeds dispersed by waterSome plants make use of water to disperse

their seeds.Plants which grow beside water often rely on

water to transport their seeds for them.A classic example is the coconut which can

help it afloat because its thick fibrous husk contains air.

Seeds dispersed by wind Fruits/Seeds which are light and thin and have hair-like or wind-like structure allowing them to be carried away by the wind.

E.g. Dandelion & Angsana

DISPERSAL OF ANIMALSo Fleshy, edible fruits with hard seeds that cannot be digested. - If seeds are large, animals throw them away after eating the fruit. - If seeds are small, animals eat them along with the fruits. Seeds pass out of their bodies through digestive system. E.g. Mango, Papaya oFruits/Seeds are small and have

hooks or stiff hair to catch on the fur of passing animals. E.g Love grass

DISPERSAL OF EXPLOSIONFruits splits open with sudden force to scatter seeds. E.g. Rubber

What are the conditions needed for the plant to grow at the crack at the wall

What are the others ways of reproduction of plant?Self reproduction Cross reproduction
