Photosynthesis 1
Where does photosynthesis occur?
Chloroplast
Please describe the flow of energy through the process of photosynthesis and cellular respiration.
Sun --> Chloroplasts absorb energy --> Glucose is stored energy --> Glucose is broken down to release ATP
Where does cellular respiration occur?
Snails need what gas to survive?
Oxygen
What is diffusion?
The movement of particles from an area of high concentration to an area of low concentration.
What types of living things do photosynthesis?
Plants and some other organisms
What gas(es) do plants produce? Why?
Oxygen and Carbon Dioxide because they have both chloroplasts and mitochondria, and do photosynthesis and cellular respiration.
What types of living things do cellular respiration?
What gas(es) do animals produce? Why?
Only carbon dioxide because they only have mitochondria and can only do cellular respiration.
The movement of water across a membrane
What are the reactants (ingredients) of photosynthesis?
sunlight, water and carbon dioxide
What are the products of photosynthesis?
glucose and oxygen
What are the reactants (ingredients) of cellular respiration?
glucose and oxygen
What are the products of cellular respiration?
ATP energy, water and carbon dioxide
To heal anybody!
What is the full equation for photosynthesis?
Sunlight + Water + Carbon Dioxide --> Oxygen + Glucose
How do plants obtain what they need for cellular respiration?
By doing photosynthesis (glucose and oxygen)
What is the full equation for cellular respiration?
Oxygen + Glucose --> ATP Energy + Water + Carbon Dioxide
How do animals obtain what they need for cellular respiration?
Breathing (oxygen) and eating (glucose)
What does semi-permeable mean?
Some things can pass, others cannot
In the plants and snails Gizmo, what happens if you have equal number of plants and snails but the lights are off?
The oxygen will disappear.
In the plants and snails gizmo, when will the level of carbon dioxide and oxygen be balanced?
HINT: number of plants/snails and whether the lights are on/off
When the lights are on and equal plants and snails are present
Thinking back to our snap cubes models for modeling photosynthesis, the reactants were simply ________________ to form the products.

Phineas and Ferb did an episode with a song about an Aglet. What is an Aglet?
The end of a shoe lace
Moving from a low concentration to a high concentration (pushing against the concentration gradient).
