What is photosynthesis? Process by which

plants and some other organisms use light energy to convert water and carbon dioxide into oxygen and high energy carbohydrates as sugars and starches. It also occurs in the plant, algae and many species of bacteria.

The point of this project is….

The project that I choose is photosynthesis and the reason why I choose this project was because it really interested me on how photosynthesis works and how is photosynthesis useful for use as humans and as plants

Where does photosynthesis takes places?

Photosynthesis takes place in the chloroplast and in the chlorophyII

ChlorophyII is what gives the leafs the color they are

Also photosynthesis has 2 parts to it: -- light dependent reaction -- light independent reactions

Light dependent reaction

The light-dependent reactions is the first stage of photosynthesis. This process capture and store energy from sunlight and light energy is converted into chemical energy and this energy is in the form of a molecule. The light-dependent reactions take place in the inside a chloroplast. Chloroplast are organelle that convert light to energy. This energy released by the molecules is called adenosine triphosphate or ATP.

Light independent reaction

The light-independent reactions of photosynthesis are chemical reactions that convert carbon dioxide and other compounds into glucose. The energy released from ATP drives this metabolic pathway. It is described to be light-independent as it proceeds regardless of the amount of light available. The term is used in contrast to light-dependent reaction of photosynthesis.

What is photosynthesis important to plants, humans, and animals?

first of all plants are important to the life because that’s some where animals and humans get oxygen from. Photosynthesis is the one that give plants with food and energy. Animals are the ones that eat the plant. For humans we breathe in oxygen and we exhale carbon dioxide.

The formula of photosynthesis….

The formula is :

6CO2+6H2OC6H12O6+602
