I use energy to drive to the store and buy the broccoli, I then take it home and use more energy to roast the broccoli with some olive oil and a pinch of salt. It is now ready for me to eat. Yumm!!!!!
After the Broccoli is transported to my local grocery market, it is stored in giant refrigerators and refrigerated display cases waiting for me to buy it
It takes the Broccoli 60-100 days to be mature enough to harvest. Harvesting takes place in 4-7 day intervals to avoid the heads of the Broccoli to become over mature. The Broccoli will mature 2-3 more times for harvesting so the entire harvest may run from 40 - 80 days depending on conditions.

Photosynthesis makes organic molecules from carbon dioxide. To build these organic molecules cells use raw materials provided by light dependent reactions. The organic molecules produces are used for the plant to grow.
These electrons are channeled through the reaction center located in the thlakoid of the chloroplasts to the electron transport chain. Next, a reaction occurs where several protons are transported across the photosynthetic membrane creating a gradient of proton concentrations
Photons are absorbed by Chlorophyll’s in the Broccoli. The chlorophyll’s contain pigment molecules that us the energy to excite electrons in their complex ring structure.
The sunlight reaches the earth in the form of electromagnetic energy. About 24% is reflected by the clouds back into space. Another 4% is reflected by the atmosphere. Roughly 19% is absorbed by gases in the atmosphere and another 3% is reflected by the earths surface. this leaves 50% that is absorbed by the earth.

Energy from the sun in the form of light or electromagnetic energy. This energy is produced by the nuclear fusion, the process of combining multiple atomic particles and creating new heavier atoms. This process releases energy that is emitted as light or photons. It takes the light about 8 minutes and twenty seconds to reach the earth.
