  2. Q1 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

  3. Why are plants so important? Q3 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. Climate: Plants store carbon, and have helped keep much of the carbon dioxide produced from the burning of fossil fuels out of the atmosphere. 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.

  4. Q4 DISPERSALOF SEEDS

  5. Types of seed dispersal • WATER • WIND • ANIMALS • EXPLOSION

  6. Seeds dispersed by water • Some 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.

  7. 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

  8. DISPERSAL OF ANIMALS • 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 • Fruits/Seeds are small and have hooks or • stiff hair to catch on the fur of passing • animals. • E.g Love grass

  9. DISPERSAL OF EXPLOSION • Fruits splits open with sudden force to scatter seeds. • E.g. Rubber

  10. What are the conditions needed for the plant to grow at the crack at the wall • Warmth • Water • Air

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