Photosynthesis
What are the Reactants for Photosynthesis?
Carbon dioxide (CO2) and Water (H2O)
What are the reactants for cellular respiration?
Oxygen (O2) and Glucose (C6H12O6)
Organisms respond to their environment because they want to maintain a constant internal state. What characteristic of life is this?
Homeostasis
In order to observe the impact of light on onion root growth, a student takes three beakers of equal parts water and places an onion in each one. One onion is in the window, another under a 24 hour bulb, and a third in a dark closet.
What is the DV of this experiment?
The length of the root growth.
What is one way living organisms release carbon?
Death, Defecation, and Exhaling CO2
What are the Products of Photosynthesis?
Oxygen (O2) and Glucose (C6H12O6)
What are the products of cellular respiration?
Carbon dioxide (CO2), Water (H2O), and ATP energy
All living organism have this hereditary material that can be passed from parent to offspring.
DNA
In order to observe the impact of light on onion root growth, a student takes three beakers of equal parts water and places an onion in each one. One onion is in the window, another under a 24 hour bulb, and a third in a dark closet.
What is the IV of this experiment?
Amount of light.
What substance must animals eat plants to get because we cannot take it in from the atmosphere?
Nitrogen
Photosynthesis requires what?
Sunlight, Chlorophyll, and Enzymes
What are the requirements for cellular respiration?
Enzymes
Gathering and using energy.
Metabolism
In order to observe the impact of light on onion root growth, a student takes three beakers of equal parts water and places an onion in each one. One onion is in the window, another under a 24 hour bulb, and a third in a dark closet.
What is one constant for this experiment?
Will Vary
These organisms take in nitrogen from the atmosphere and "fix" them for plants to use.
Bacteria
What is the purpose of photosynthesis?
Change light energy into chemical energy (glucose)
What is the purpose of cellular respiration?
To change chemical energy (glucose) into ATP
Cellular Respiration occurs in...
-autotrophs ONLY
-heterotrophs ONLY
-autotrophs AND heterotrophs
autotrophs AND heterotrophs
What is the part of an experiment that we use as a baseline for comparison?
Control
This property of water allows water molecules to be drawn up plants through capillary action because they "stick" together. Also known as _________
Cohesion
Where does Photosynthesis take place?
Chloroplast
Where does cellular respiration take place?
Mitochondria
What three parts make up the life cycle?
Reproduction, Growth, and Death
In order to observe the impact of light on onion root growth, a student takes three beakers of equal parts water and places an onion in each one. One onion is in the window, another under a 24 hour bulb, and a third in a dark closet.
Write a HYPOTHESIS for this experiment.
If I change the amount of light for three different onions, then the roots will grow different lengths.
What property allows some organisms to stand on water without falling through?
Surface tension
