Photosynthesis
What happens in the first and second stages of photosynthesis?
1) Capturing energy from sunlight and 2) The cells use the captured energy to produce sugars
What is the chemical equation for photosynthesis?
6 CO2 + 6 H2O = C6 H12 06 (six carbon dioxide + six water with sunlight results in one molecule of glucose and six molecules of oxygen)
What is the symbol for carbon dioxide?
CO2
How do heterotrophs get energy from the sun?
Eating plants.
what is the symbol for water?
H20
What happens in the first stage of photosynthesis?
Involves capturing the energy in sunlight. The energy capturing process occurs in the leaves and other green parts of the plant. The chloroplasts give the plants their green color. Chloroplasts contain chlorophyll which is the pigment that absorbs light. The captures energy is used to power the 2nd stage of photosynthesis
What happens during photosynthesis?
Plants (and some organisms) use energy from the sun to convert carbon dioxide and water into oxygen and sugars (including glucose).
How does a plant obtain water?
Root system
What is stomata?
Small openings on the undersides of the leaves through which carbon dioxide enters the plant.
What happens in the second stage of photosynthesis?
The cells use the captured energy to produce sugars.
What is chlorophyll? Why is it important?
The main pigment found in the chloroplasts of plants. The pigment chlorophyll capture energy from light.
What is photosynthesis?
The process by which a cell captures energy in sunlight and uses it to make food.
Nearly all living things obtain energy either directly or indirectly from the energy of sunlight captured during photosynthesis. True or false?
True
True or false? Photosynthesis is also essential for the air you breathe. Almost all the oxygen in Earth's atmosphere was produced by living things through the process of photosynthesis.
True
What two raw materials do cells need for the second stage of photosynthesis?
Water and carbon dioxide.
