Process of Photosynthesis
What is the main purpose of photosynthesis?
To convert sunlight into energy for the plant.
What is the process by which plants convert glucose into energy?
Cellular respiration
What is transpiration?
The process of water vapor leaving the plant through the leaves.
How do plants obtain sunlight?
Through their leaves.
Name one example of a vascular plant.
Trees, flowers, or ferns.
Structures or behaviors that help an organism survice in its environment?
What are adaptations
Which two substances are needed for photosynthesis to occur?
Carbon dioxide and water
What do plants release during respiration?
Carbon dioxide
What is the main purpose of transpiration?
To cool the plant and help with nutrient uptake.
Why do plants need nutrients from the soil?
To support growth and development.
Name one example of a nonvascular plant.
Moss
Plants stop growing for a time.
What is dormant?
What is produced as a byproduct of photosynthesis?
Oxygen
How does respiration differ from photosynthesis?
Respiration releases energy, while photosynthesis stores energy.
How does transpiration contribute to the water cycle?
It releases water vapor into the atmosphere.
What role do roots play in meeting a plant's needs?
Roots anchor the plant and absorb water and nutrients.
How do vascular plants differ from nonvascular plants?
Vascular plants have tissues for transport, while nonvascular plants do not.
A plant growing toward light
What is phototropism?
In which part of the plant does photosynthesis primarily take place?
In the leaves
Why is respiration important for plants?
It provides the energy needed for growth and other functions.
What factors can affect the rate of transpiration?
Temperature, humidity, wind, and light.
How do plants interact with animals to meet their needs?
Animals may help pollinate plants or disperse seeds.
What environments do nonvascular plants thrive in?
Moist environments.
A plant twines around an pole to help it grow or a plant folds up its leaves in response to touch.
What is thigmotropism?
What pigment is responsible for capturing sunlight in plants?
Chlorophyll
What is the formula for cellular respiration?
C<em>6H</em>12O6+6O2→6CO2+6H2O+energy
What is the role of stomata in transpiration?
Stomata are openings that allow water vapor to escape.
What is symbiosis in the plant kingdom?
A relationship where plants and other organisms benefit from each other.
Why are vascular plants generally larger than nonvascular plants?
They can transport water and nutrients more efficiently.
Plants response to gravity. Roots grow down and anchor plant in the soil.
What is gravitropism?
