part 1
List the Main Parts of the plants
Root, Stem , leaves, flower , fruits
What do plant need to survive?
Water, Air , Sunlight , Space , Soil
What is meaning of energy?
Is the ability to do work or change something
What is the main source of energy to the plant or on Earth?
Sunlight
What do you Know about plants?
made of many cells, make their own food, need water, sun light and carbon dioxide to make sugar and release oxygen
what are the functions of the roots?
absorb water and minerals from the soil
Anchor the plant in the soil.
what are the functions of the stem?
Carry water and food through the plants
support the plant
What is the function of the leaves?
Make the food for the plant
What is the function of the stomata?
opening at the lower surface of the leaves that control gasses exchange .
what is the function of the flower and fruits?
flower is the reproductive part of plant (produce seeds)
but fruits protect the seeds
What factors could affect plant growth?
Type of soil, Space, amount of water, amount of sunlight
Compare between the function of xylem and phloem.
Xylem : Is a tissue (tube) that carry the water and nutrients from the soil to the plant
move in one direction only (up)
Phloem : Is a tissue (tube) that carry the food from the leaves to all parts of the plant.
move in all the direction.
Describe photosynthesis process
Photosynthesis process that plant makes its own food from water, Carbon dioxide and sunlight to make food and oxygen
Describe transpiration process
Transpiration is the evaporating of water from the plant leaves through the stomata.
Explain why do plants very important to our life?
Because plants make their own food and we use the plant as energy source
Why would it be a disadvantage if plants grow too close together?
Because plants that grow too close together compete for the same resources or need more space to grow bigger.
What is the environmental factors that would increase transpiration
Increase Temperature
How plants can adapt to live in the desert?
Examples cactus and Ghaf Tree
Plants can store water, Need less amount of water
small leaves to decrease water lose
what can control the opening and closing of stomata?
Stomata open to let CO2 in and H2O and O2 out
close to limit the lose(evaporate) of the water
plants can grow with or without soil, Explain.
plants can grow with or without soil as plants get what it need (water and nutrients) from the soil. in soil less garden no soil and plants get what it need from nutrients water solution
