Flower Parts & Functions
What part of the flower produces pollen?
stamen or anther
What type of dispersal allows seeds to travel by wind?
Wind dispersal
What stage comes after a seed germinates?
Growth (seedling develops roots, stem, leaves)
Where does photosynthesis take place in the plant?
The Leaves
Which part of the plant absorbs water?
Xylem
Which part of the flower receives pollen for fertilization?
pistil or stigma
Which dispersal method involves animals carrying seeds on their fur or eating them?
Animal dispersal
What happens during pollination?
Pollen is transferred from the stamen to the pistil.
What is the xylems job?
to carry water from roots to leaves
A dandelion seed has a fluffy parachute. What type of dispersal is this?
Wind Dispersal
What part of the flower protects the developing bud before it opens?
Sepal
Name one type of mechanical dispersal and explain how it works.
Exploding pods — seeds are ejected from the pod to spread to new locations.
What forms inside the ovary after fertilization?
seeds or fruit
Which plant part carries food from leaves to other parts of the plant?
The Phloem
Which gas do plants take in for photosynthesis?
Carbon Dioxide
Name the male parts of a flower and describe their role.
Stamen (anther produces pollen, filament holds anther)
How does water dispersal help seeds survive and grow?
Seeds can float to new locations, increasing chances to find suitable soil and reducing competition.
List the main stages of a flowering plant’s life cycle in order.
Seed → Germination → Growth → Flowering → Pollination/Fertilization → Seed Formation & Dispersal
Name the three main things plants need for photosynthesis.
Sunlight, water, carbon dioxide
Explain in 1–2 sentences how the xylem and phloem support plant survival.
Xylem carries water and minerals from roots to leaves; phloem transports food made in leaves to the rest of the plant.
Explain the role of petals in plant reproduction and why their characteristics matter.
etals attract pollinators through color, shape, or scent, increasing the chances of pollination.
Explain why it is important for seeds to be dispersed far from the parent plant.
Reduces competition for sunlight, water, and nutrients; allows plants to colonize new areas; increases survival chances.
Explain why reproduction is important for plant species survival.
Reproduction makes sure the species continues to live for a long time. Seeds allow plants to spread and survive environmental changes, preventing extinction.
Explain how roots, stems, and leaves work together to help the plant survive.
Roots absorb water and nutrients, stems transport water and food via xylem and phloem, leaves make food through photosynthesis, supporting growth, reproduction, and survival.
A plant produces seeds that stick to animal fur, and some seeds float in water to new locations. Explain why having multiple dispersal methods increases a plant species’ chances of survival.
Using multiple dispersal methods increases the likelihood that seeds will reach safe places to grow, reduces competition with the parent plant, and helps the species survive in different environments or if one method fails.
