But some haploid organisms have a fertilization event that produces dipoloid cells which then undergo meiosis to give you haploid cells again. So, if the haploid organism undergoes some form of sexual reproduction, then YES, it carries out meiosis.

RE:
does meiosis occur in organisms that are haploid?

Haploid organism first fuse sex cells (often the entire adult cell) to form a diploid zygote. The zygote undergoes meiosis to produce haploid offspring. This is common in many protistans such as algae and protozoa.

No, haploid cells are the products of meiosis. Diploid cells undergo meiosis to create the haploid cells. A cell with only one set of chromosomes cannot be reduced further.

Haploid cells having only one set of chromosomes cannot form the bivalents (or pairs) in the cells' equatorial region, as a prelude to separation of chromosomes. So how do they separate out again (as per the second answer). The only possibility the so called haploid cells can form bivalents and separate out again are if they are diploid (amphidiploid, that is) to start with. In which case the plant (very rare or absent in animals) would have been polyploid to start with. Am I right?

I agree with the 2nd answer, some halpoid plants undergo meiosis to make diploids.

No. Just mitosis.
