Roots & Support
Which plant part anchors the plant and absorbs water and minerals from the soil?
roots
What green pigment in leaves captures sunlight for photosynthesis?
Chlorophyll.
Which part of the flower is the male structure that makes pollen?
Stamen.
What is the name for transferring pollen from the stamen to the pistil?
Pollination
Which plant structure provides support and transports water and nutrients between roots and leaves?
stem
Plants take in CO2CO2 and water and use sunlight to make two main products. Name those two products.
Sugar and oxygen
Which part of the flower is the female reproductive structure?
Pistil.
List three typical ways pollination occurs (name three)
Wind, animals (insects, birds, bats), water
Explain why roots are important for a plant’s survival beyond just absorbing water (one or two sentences).
Roots store food, anchor plant, prevent erosion, etc. (400)
Write the three things a plant needs to begin photosynthesis (three short answers).
Sunlight, water, and carbon dioxidecarbon dioxide
Which part of the flower protects the bud before it opens?
Sepal
How does pollination help a plant reproduce? (Short answer.)
Pollination moves pollen so fertilization can occur and seeds form
Name two ways roots help an ecosystem (answer two distinct functions).
prevent erosion, store food, help water uptake; any two.
Where in the plant does photosynthesis mainly occur? Be specific (which plant part and where in that part).
Leaf — specifically the chloroplasts in the leaf’s mesophyll cells
Which flower part is often colorful and scented to attract pollinators, and why is that useful?
Petals — attract pollinators so pollen can be transferred, helping reproduction
For a population of plants or animals to continue to exist, what must they be able to do?
Reproduce
A tree’s leaves are all eaten by insects (the Beetle Dilemma). Using photosynthesis ideas, explain why the tree might die.
Loss of leaves removes the plant’s ability to photosynthesize (make sugar). Without sugar and energy, the tree cannot grow, repair, or maintain cells and will eventually die; roots and other tissues will weaken.
Explain how photosynthesis helps both plants and animals survive (2–3 sentences).
Photosynthesis produces food (sugar) for the plant and oxygen for animals to breathe; animals eat plants (or eat animals that ate plants) for energy.
Identify which plant part is responsible for making seeds and briefly explain how seeds form after pollination (2–3 sentences)
Ovary (part of the pistil) makes seeds after pollen fertilizes ovules; seeds form in the ovary and develop into new plants.
Plants take in ____________________ and ____________________ during photosynthesis; they produce ____________________ as food and release ____________________ into the air." | sunlight | pistil | flower
water | pollination | sugar
carbon dioxide | reproduce | sepal | oxygen
Plants take in carbon dioxide and water during photosynthesis; they produce sugar as food and release oxygen into the air.
