Plant Transport System
What plant part moves water and dissolved nutrients from the roots to the leaves?
Xylem
Where does photosynthesis take place in a plant?
Leaves
Which flower part makes pollen?
Stamen
What is one job of roots?
Absorb water or anchor the plant.
What are stomata?
Tiny openings on leaves
What do we call a scientist who studies plants?
Botanist
What plant part moves food from the leaves to the rest of the plant?
Phloem
What tiny structures in leaves capture sunlight?
Which flower part receives pollen?
Pistil
What structures inside the stem help move water and food?
Tube-like structures/Vascular tubes
What gas do plants take in through stomata?
Carbon Dioxide
Name ONE way seeds can travel.
Wind, water, or animals
What system is made up of xylem and phloem working together?
Vascular System
Name THREE materials needed for photosynthesis.
Sunlight, Water, Carbon Dioxide
What flower part helps attract pollinators like bees?
Petals
Which root system is best for finding deep water in dry areas?
Taproot
Why do plants close stomata on hot or dry days?
To prevent water loss
Why is seed dispersal important for plants?
It helps new plants grow in new places.
If a plant's phloem stopped working, which part of the plant would NOT get food?
The roots and other non-leaf parts
What would happen to photosynthesis if a plant did not receive sunlight?
The plant could not make food.
What is the job of the ovary in a flower?
It holds ovules and helps make seeds.
Why would a plant in a windy environment need a thick stem?
To support the plant and prevent breaking.
How do stomata and the cuticle work together to help a plant survive?
Stomata control gas exchange and the cuticle reduces water loss.
What might happen if all seeds fell directly next to the parent plant?
Plants would compete for water, sunlight, and space.
Explain why xylem and phloem must work together for a plant to survive.
A plant is placed in the dark for several weeks. Predict what will happen and explain why.
It will weaken or die because it cannot make food without sunlight.
If a plant could not be pollinated, what would happen to its ability to reproduce? Explain.
It would not make seeds, so new plants could not grow.
Compare a plant in a windy area to one in a calm area. How might their stems be different and why?
Windy-area plants need thicker, stronger stems for support.
What cells control when stomata open and close?
Guard Cells
Explain how seed dispersal helps plants survive over time.
It spreads plants to new areas and reduces competition.
