Created new term 'microbody ; GO:0042579' as suggested. Child of 'cytoplasm' with children 'glyoxysome' and 'peroxisome'.

Glyoxysomes and peroxisomes are microbodies. So could we have the additional term "microbody" ?
The dictionary of Cell and Molecular Biology: peroxisome Organelle containing peroxidase and catalase, sometimes as a large crystal. A site of oxygen utilization, but not of ATP synthesis. In plants, associated with chloroplasts in photorespiration and considered to be part of a larger group of organelles, the microbodies. Author: Chris Brett
http://courses.forestry.ubc.ca/frst200/lectures/Lecture5.pdf. Microbodies: There are two basic types of microbodies: glyoxysomes (plants only) and peroxisomes (in both plants and animals). Glyoxysomes convert fats into carbohydrates to be used in respiration. They're important during germination of many seeds. In plants,peroxisomes play an important role in a process called photorespiration. Oxygen interferes with photosynthesis by competing with CO2 . Photorespiration is apparently wasteful of carbon and energy. Peroxisomes help recover some of the carbon. In the process, they make a lot of hydrogen peroxide (H2O2), which is toxic and must be immediately broken down into water and oxygen again, which y also do.
