Why are flowers so colorful? How does this connect to reproduction?
A. Flowers use bright colors to keep predators away from the plant’s roots while seeds grow.
B. Flowers are colorful so they can absorb more water from the soil during reproduction.
C. Flowers are colorful to attract pollinators like bees and butterflies, which helps plants reproduce by spreading pollen.
D. Flowers are colorful because the petals store food that helps new plants reproduce.

Leaf, stem, roots
400
Define function and give an example.
Function is the role or job of a structure. For example, the function of the xylem is to move water from the roots to the rest of the plant.

500
Draw a model of a flower and label the key reproductive structures.
Must have labeled: sepals, petals, stamen, pistil
500
Why is it important that plants do photosynthesis? Be specific.
Photosynthesis helps plants make their own food using the sun's energy, water, and carbon dioxide so they can grow and survive.
Bonus: Plants turn the carbon dioxide we exhale into oxygen for us to breathe again!
500
Define and explain the process of photosynthesis.
Photosynthesis is the process plants use to make their own food. Plants take in sunlight, water, and carbon dioxide and use them to create sugar for energy and oxygen that is released into the air.
