Photosynthesis and the Leaf

                                       Photosynthesis and the Leaf

                           Hello guys and welcome back to my lastest post. www.phschool.com/science/biology/_place/biocoachToday we are gonna be talking about how the leaf works and photosynthesis.

First we have off is how photosynthesis works. All living things like us need nourishment to grow, but plants on the other hand make their own food through photosynthesis. There would be no plants without the sun to provide them sunlight. Plants collect sunlight to make a sugary ingredient called glucose. It is the main source of nutrition for plants, fueling their cells for growth and development.
It's definetly no secret that plants use their roots to drink up water from the soil and its nutrients. Water travels from the roots to the plants leaves through a transport tissue called xylem which is wood in trees. Another fact is, leaves absorb CO2 from the air through the openings called the stomata. The equation for photosynthesis is CO2 + H2O + Energy = CH2O + O2.

The water and carbon dioxide spread through the leaves into cells called the palisades and spongy cells. These cells contain rigid and squiggly structures called chloroplasts, which are filled with chlorophyll.
























  
Chlorophyll is what makes plants green. In photosynthesis chlorophyll catches energy from sunlight and using it as chemical energy. This process splits water molecules into H2O. This kind of energy can produce a sugar called glucose. The sugar is way different from the sugar that we take in. Sugar can make us really hyper if we take too much in. The sugar glucose can dissolve into extra water molecules and makes the plant grow.

The leaves release oxygen as a waste product the one we breath in. Without the plants their would be no life on earth. We breath in oxygen and exhale CO2 and plants breath in CO2 and they leave out oxygen.




See you guys later. I guess.
