1. Changing States
What is the boiling point of water? What is the melting point of water?
The boiling Point of Water: 100°C
The melting Point of Water: 0°C
What is germination?
The development of seeds into young plants is germination
Why do plants produce flowers?
Flowering plants do not produce flowers to make the place beautiful. They produce flowers for reproduction.
What is boiling?
What is melting?
The change of a liquid into a gas at its boiling point is called boiling.
The change of a solid into a liquid is called melting.
What do seeds need to geminate in general?
What do plants need to grow?
In general, seeds need water, warmth and air to geminate.
Plants need light energy to make food. Plants need air to stay alive. Plants need water to keep firm.
Why do plants need to reproduce?
Plants reproduce so that they not become extinct.
What is the water cycle? Why is it important?
Water cycle is the continuous movement of water from the Earth's surface to the air and back to the Earth's surface.
The water cycle provides livings with a constant supply of fresh water.
Plants cannot make their own food without light. Why?
Without Light:
The process of photosynthesis stops.
The plant can’t produce glucose, which it needs for energy and growth.
How are flowers pollinated?
Pollination happens with the help of:
Insects (like bees, butterflies)
Wind
Birds (like hummingbirds)
Water
Animals
What is evaporation?
The change of a liquid into a gas is called evaporation. Unlike boiling, which takes place at the boiling point, evaporation can take place at any temperature.
What are parts of a bean? What are the functions of seed leaves and the seed coat?
Parts of a bean seed: 1. Seed coat, baby plant, seed leaves.
Seed leaves store food
The seed coat cover and protect the seed.
The baby plant will develop into a young plant if conditions are right.
What is involved in the reproduction of flowering plants from seeds?
Pollination
Fertilization
Seed production
Seed dispersal
Seed germination
What affects the rate of evaporation?
How quickly evaporation takes place is known as the rate of evaporation.
The rate of evaporation depends on the following
1. The temperature of the surroundings.
2. The presence of wind
3. The surface area
What is photosynthesis?
Plants can make their own food in a the process called photosynthesis. Photo means light, synthesis means putting simpler or smaller parts together to make something more complex.
What is pollination?
Pollination is the transfer of pollen grains from the anther to the stigma of the same flower of another flower.
