6th gr. cmk How and Why Plants Make Food

STUDY
PLAY
All living things, including plants, need food to give them ___________?
ENERGY
What does energy do for plants?
energy fuels life processes and materials (molecules) to build and repair their bodies
How do plants make food?
Through a process called PHOTOSYNTHESIS
What is needed for photosynthesis?
1. H2O (water)
2. CO2 (carbon dioxide)
3. light (sun)
What is made by photosynthesis?
1. Sugar (glucose)
2. O2 (oxygen)
Here is a summary of photosynthesis
Water (H2O) + Carbon dioxide (CO2) + Sunlight = Sugar + Oxygen (O2)
What do plants do with the food they make?
1. Store it (as fats, carbohydrates, proteins)
2. Use it (for energy and materials for life)
How do plants (and other organizms) use food?
Through a process called CELLULAR RESPIRATION
What is needed for cellualr respiration?
1. Sugar (glucose)
??? 2. O2 (oxygen) ????
What is made by cellular respiration?
1. H2O (water)
???? 2. CO2 (carbon dioxide) and Chemical energy for life is released (not "made")
Here is a summary of cellular respiration
Sugar + Oxygen = Water + Carbon Dioxide+ Energy for life
Plant bodies have special structures to help them with photosynthesis and cellular respiration, These include:
1. Stomates
2. Xylem
3. Phloem
4. Roots
5. Chloroplasts
6. Mitochondria (these are in plants AND animals)
Stomates: What they do and where they are found
What do: Let CO2 in, let O2 and H2O out
Where found: Mainly on leaves, they look like small mouths
Xylem: What it does and where found
What do: Carries H2O around the plant
Where: Thin tube that runs through the plant from roots through stem to leaves
Phloem: What it does and where found
What do: Carries sugar
Where: Thin tube that runs throughout the plant
Roots: What does and Where found
What do: Take in water and nutrients and attach plant to the ground
Where: Underground
Chloroplasts: What is does and where found
What do: Photosynthesis happens here
Where: In the cytoplasm of leaves and other green plant cells
Mitochondria (these are in plants AND animals)
What do: Cellular respiration happens here
Where: All plant and animal cells
Transpiration
Energy from the sun causes water molecules to evaporate out of the stomate. As a water molecule leaves, it pulls on the molecule behind it. The pull continues all the way down the plant and into the the roots, bringing more water into the plant.
Transpiration:
_____ from the sun causes water molecules to evaporate out of the ____________
Energy
Stomate
The pull on water molecules in transpiration continues all the way down the plant and into the ____, bringing more water into the ______
Roots
Plant
Water molecules attract each other because they are______
Polar
Polar
have one positive side and one negative side
What surrounds the stomate?
gaurd cells
Veins have what in them?
xylem and phloem
Leaf cells contain ______.
Chloroplasts
Chloroplasts have _____ to trap energy from the sun?
Chlorophyl
Chlorophyl traps _____ from the sun.
energy
The trunk of the tree includes ____ & ____ to carry water and sugar/food
xylem
phloem
Xylem and phloem in a tree trunk carry _____ & ____
water
sugar/food
Root hairs do what?
Absorb water and nutrients
