Study Notes
Photosynthesis
- Glucose, also known as sugar, has the molecular formula C6H12O6.
- Plants create sugar by using sunlight to convert CO2 from the air and water from the ground into glucose.
- Photosynthesis occurs in the chloroplast of plant cells.
- Oxygen (O2) is created as a waste product and released into the air.
- The formula for photosynthesis is: CO2 + H2O + sunlight -> C6H12O6 + O2
Reactants and Products
- Carbon dioxide and water molecules combine using sunlight to produce sugar and oxygen.
- The reactants in photosynthesis are CO2, water, and sun.
- Plants get water from the ground through their roots.
- Plants collect carbon dioxide from the air, mainly from living organisms, factory smokestacks, and car fumes.
- The formula for photosynthesis: CO2 + H2O + sunlight -> C6H12O6 + O2
- Three things used to make glucose: carbon dioxide, water, and sunlight.
- Water comes from the soil underneath the plant.
- Water enters the plant through the root system.
- Three sources of CO2: living organisms, factory smokestacks, and car fumes.
- Plants use light energy to convert CO2 and H2O into sugar.
- The products of photosynthesis are glucose and oxygen.
- Plants use glucose for energy and growth.
- Humans use glucose by eating plants.
- Oxygen produced is released into the air.
- Photosynthesis is essential for life, providing food and oxygen.
- Plants are autotrophs, making their own food.
- Glucose and oxygen are produced in photosynthesis.
- Glucose is used for energy and growth.
- Oxygen is used for breaking down sugars and releasing energy.
Chloroplasts
- Photosynthesis is the process in which sunlight energy is used to make glucose.
- Photosynthesis occurs in the chloroplast, an organelle in green plant leaves.
- Main functions of chloroplasts include producing food (glucose) during photosynthesis and storing food energy.
- Chloroplasts contain the pigment chlorophyll.
- Chlorophyll absorbs most colors in the color spectrum, reflecting green and yellow light.
- Leaves appear green or yellow because these colors are reflected.
- Photosynthesis: a plant making food to grow.
- Photosynthesis occurs in the chloroplast.
- Chloroplast is an organelle that produces food during photosynthesis and is found in the leaves of green plants.
- The two main functions of chloroplasts are to produce food and store energy.
- Leaves appear green because chlorophyll reflects green and yellow light.
- Chlorophyll is the primary pigment found in chloroplasts.
