Get unlimited access to over 88,000 lessons. [5] Currently, 15 recognised genera are in the family. The gametophyte form of the plant produces gametes, which come together and form a zygote that will develop into the sporophyte, the diploid generation of the plant. Another example of a halophile can be found in the salty lakes of Botswana. Heterotrophs obtain their energy by consuming other organisms. This means they are all composed of one cell and do not have a nucleus or membrane-bound organelles in the cells. Astrobiologists are also studying the possibility of these organisms being found on Mars.
