Could Earth Survive with Artificial Photosynthesis?

I do not think that earth could, right now, survive on artificial photosynthesis. Photosynthesis is the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct. Even though artificial photosynthesis apparently […]

Photosynthesis in Plants and Bacteria

Photosynthesis in plants and a few bacteria is responsible for feeding nearly all life on Earth. It allows energy from the sun to be converted into a storable form, usually glucose, which plants use to grow. Photosynthesis also generates the oxygen that animals need to survive. We exhale the carbon dioxide that plants need for […]

The Effects of Photosynthesis on the Atmosphere

During photosynthesis, plants take in carbon dioxide and emit oxygen into the atmosphere. The oxygen produced from photosynthesis makes it possible for animals and humans to breathe. “”A single mature tree can absorb carbon dioxide at a rate of 48 lbs/year and release enough oxygen back into the atmosphere to support 2 human beings” (McAliney,1993). […]

General View of Photosynthesis

Photosynthesis is a physiological process by which green plants, algae and some forms of bacteria utilize energy from sunlight to convert carbon dioxide and water into sugars. For the process of photosynthesis, plants require light energy from the sun, water and carbon dioxide (Johnson, 2016). This process takes place in two steps, one is light […]

Introduction to Photosynthesis

Light-Dependent Reaction The energy releasing light-dependent responses of photosynthesis change light energy into the compound energy; this creates ATP and NADPH. These responses happen in the heaps of thylakoids of the chloroplasts. The results of the light-dependent responses, ATP and NADPH, are both required for the energy-requiring light-independent responses. Light-Independent Reaction The energy-requiring light-independent reactions […]

Stem Cells and Reverse the Aging Process

To delay or perhaps, reverse aging is a topic that occupies the mind of many researchers. Stem cells are tools that help study aging because : they divide and renewing themselves for long periods,they differentiate into different cell types as they are initially unspecialized. These cells are immortal, they do however decrease in functioning as […]
