What's the diffrence between the stems of many plants and the stems of trees?
Plants: Green + Soft + flexible + carry out photosynthesis like leaves/ Trees and bushes: hard rigid stems
Explain: Chlorophyll
- A green subtance inside of chloroplast - makes leaves green - captures energy from the sun
Why are roots important? (3)
1- stabilize.the plant / 2- store food made by leaves / 3- absorb water and minerals from the soil
What do plants need to make their food?
Sunlight / Carbon Dioxide / water
Explain: How plants make their food ( the process of photosynthesis )
water and minerals (roots) + Carbon dioxide (leaf) + sunlight (captured by chlorophyl) = Combine to make food in the leaves
What helps the chlorophyll in leaves catch sunlight?
The shape and positioning helps them catch sunlight to make food
What is the site of photosynthesis ?
Chloroplast
Explain: Fibirous roots (2) and give examples (3)
many and spred in all directions+ grow close to surface. Examples: Grass/ pine trees/ cactus
What protects the stem and prevent them from dying out?
Waxy covering
What is moisture?
The presence of water in the air
What is the leaves' function in the process of photosynthesis?
1- Absorb carbon dioxide / 2- the chlorophyl inside of leaves captures energy from the sun
Explain: Chloroplast (3)
- A tiny structure containing chlorophyl - The site of photosynthesis - dak green disks connected by threadlike materials
What do plants release in the process of photosynthesis?
Oxygen
What are airplants?
- Don't have roots / - Make food by absorbing moisture from the air
What is the meaning of "Photosynthesis" ?
The process that helps leaves make food.
Types of roots (2)
Taproots: 1 large root + grow deep in the soil (gravity) + carrots, beetroots, raddish / Fibrous roots: many and spred in all directions+ grow close to surface
Explain (2) : Taproots and give examples (3).
1 large root + grow deep in the soil (gravity) + carrots, beetroots, raddish
Types of leaves:
- Most of them are flat - Clover (circle leaf pattern ) - Ash trees (opposite leaf pattern) - Grape vines ( staggered, zigzag leaf pattern)
Plants food is a kind of ...
sugar
In what position do stems grow?
Up towards the light
What is the roots' function in the process of photosynthesis ?
Absorb water and minerals from the soil.
What do chloroplasts contain?
Chlorophyll
Leaves contain.................. that contains ...........................
