Homeostasis
Define Homeostasis
Maintaining a balance in living things
(teacher determines correct response)
Define Photosynthesis
The process where plant cells create food from water, CO2 , and sunlight
Define Cellular Respiration
The process in a cell where energy is released from combining glucose and oxygen
What is the Carbon Cycle?
The process in which carbon is moved throughout the planet
What process can reduce the amount of carbon in the air and water?
Photosynthesis
What are some ways that cells maintain homeostasis?
Removal of waste, regulation of water, regulation of glucose, reproduction, regulation of body temperature
What organelle is responsible for photosynthesis
Chlorophyll
What organelle is responsible for cellular respiration?
Mitochondria
How do plants contribute to the carbon cycle?
Plants are made of carbon and take in carbon dioxide.
Solve for x:
4x-x+5= 9 + x
4x - x + 5 = 9 + x
3x + 5 = 9 + x
2x + 5 = 9
2x = 4
x = 2
Define Diffusion
The movement of a substance from an area of high concentration to an area of low concentration
What does photosynthesis do to the energy from the sun?
Stores it in sugar
What does cellular respiration do to the energy from the sun?
Releases it from sugar
How do animals contribute to the carbon cycle?
They eat plants and other animals which transfers the carbon to them
Do plants need oxygen to survive? Why or Why not?
Yes, they also undergo cellular respiration, so they need some oxygen
Define Osmosis
The movement of water
What "Waste" products are created from photosynthesis
Glucose and Oxygen
What "waste" products are produced from cellular respiration?
Carbon Dioxide and water
How to decomposers contribute to the carbon cycle?
They break down living things and release carbon into the air and ground.
What is the capital of Spain?
Madrid
How do solutes control Osmosis?
Water will move towards areas with higher concentrations of solutes.
What is the chemical equation of photosynthesis?
Carbon Dioxide + Water + Energy ----> Glucose + Oxygen
What is the chemical equation of cellular respiration?
Glucose + Oxygen -------> Carbon Dioxide + Water + Water
What human activities can cause more carbon to enter the atmosphere?
Burning things, pollution from cars, deforestation
What is the answer to life the universe and everything?
