Blood is fluid connective tissue that consists of two main components, plasma and formed element. Blood plasma is a clear extracellular fluid, which is a mixture of proteins, enzymes, nutrients, wastes, hormones and gases. Formed elements are made up of the blood cells (red blood cells and white blood cells) and platelets. All formed elements are cells except for the platelets, which are tiny fragments of bone marrow cells.
The formed elements can be separated from plasma by centrifuge. On separation of blood components, it is evident that formed elements make up 45% of total blood volume while the plasma makes up 55% of the total volume.

The molecule produced by light reactions in plants and used by some bacteria for cellular respiration is oxygen. Photosynthesis occurs only in the light, whereas cellular respiration occurs in both the light and the dark. Complex organic molecules release energy during cellular respiration, but they store energy during photosynthesis.
The majority of autotrophs, or organisms that do not rely on external food sources, obtain the majority of their energy from light reactions. These organisms are known as photoautotrophs. When light is present, chemical reactions known as "light reactions" occur. Photosynthesis is the plant-based light-induced reaction.
This is the process of converting light energy into chemical energy. The sun's light energy is converted into the compounds ATP and NADPH during this process (nicotinamide adenine dinucleotide phosphate).
