50 POINTS AND BRAINLIEST... SOMEONE PLEASE HELP ME.... Explain the processes that take place in the stroma including the reactan
ts going in and the products produced from these processes in (a) bright sunlight in (b) darkness. (c) what happens over an extended period of darkness of many days?
During the first part, during sunlight that is, pyruvatric acid is augmented during proton formation. This is where oxygen is formed at a rate of 150 ppm. During darkness, the carbon is oxidized and allowed to build up, which will ultimately produce more water (which is important for plants and other photosynthesizing organisms) and power the processes that make fructose and sucrose (ie: sugars). Over extended periods of darkness, this build up of sugar is able to keep the plant from deteriorating and can help it go dormant (kind of like hibernating) until conditions improve.
Mitosis occurs when the body needs more diploid cells, for example to heal a cut on the skin. Meiosis is the formation of 4 haploid sex cells, or gametes.
