Plants
What is the main function of roots?
To absorb water and nutrients from the soil and anchor the plant.
What is the role of petals in a flower?
To attract pollinators with color and scent.
What is the primary source of energy for an ecosystem?
The Sun
What is the main method of reproduction for flowering plants?
through seeds produced by flowers.
What gas do plants take in during photosynthesis?
Carbon dioxide (CO₂)
What tissue in vascular plants transports water?
Xylem
Which part of the flower contains pollen?
The anther (part of the stamen)
Define a producer in an ecosystem.
An organism that makes its own food (usually a plant).
Define pollination
The transfer of pollen from the anther to the stigma
Where does photosynthesis occur in a plant?
In the chloroplasts of plant cells
What are the small openings on leaves called that allow gas exchange?
Stomata
What is the function of the ovary in a flower?
It contains ovules and develops into fruit after fertilization
How do nonvascular plants obtain water?
They absorb water directly through their surfaces
What is a seed?
A seed is a plant embryo enclosed in a protective covering with stored food.
What is the product of cellular respiration?
Carbon dioxide, water, and energy (ATP)
Define tropism
A plant’s growth response to an environmental stimulus
Name the part of the flower that attracts pollinators
Petals
How does energy transfer from one trophic level to another?
When one organism eats another, energy is passed along the food chain.
What part of a plant is the male?
the stamen
How are photosynthesis and cellular respiration related?
Photosynthesis makes the glucose and oxygen used in respiration; respiration releases energy and carbon dioxide used in photosynthesis
What structure protects the flower before it blooms?
The sepal
What is the purpose of the sepals?
To protect the flower bud before it opens
Why are vascular plants usually taller than nonvascular plants?
Because they have vascular tissue to transport water and nutrients efficiently
What is the role of fruit in plant reproduction?
Fruit protects the seeds and helps with seed dispersal.
Where does cellular respiration take place?
Mitochondria
