gametangia
A gametangium is a structure in fungi, algae, and some plants that produces and encloses gametes for sexual reproduction. It can contain male gametes (sperm) or female gametes (eggs) or both. Gametangia are often specialized structures that allow for the fusion of gametes to create a zygote.
Flagellated gametes
How are gametes formed?
The Male Gametes are formed in the testicles.
A zygote is a cell formed by the union of two gametes (sperm and egg) during fertilization. This single-celled structure contains a complete set of chromosomes, half from each parent, and is the starting point of the development of a new organism.
With Hh genotype, two types of gametes can be formed: H gametes and h gametes. This is because each parent can pass on either the dominant allele (H) or the recessive allele (h) to their offspring.

When Chlamydomonas species reproduce sexually. The haploid cell divides first by mitosis to produce haploid gametes. After those gametes are released, a pair of gametes from diffrent Chlamydomonas individual fuse to form a pair. Each gamete sheds its cell walls. Then the gametes fuse into a diploid zygote with a thick protective wall called a Zygospore.
No gametes are formed in asexual reproduction because they are only formed in sexual reproduction. Many cells can come from one cell in asexual reproduction which is really a cloning process, but not gametes.
