Analysis:
1. We viewed a unicellular green algae (chlorophyta) called chlamydomonas, a colonial green algae called volvox, and another colonial green algae called spirogyra. I knew the forms of these species because under the microscope, I could view all the cells in each species and match them to examples given in our notes. It was clear which of them had single cells and which of them had cells next to each other in the colonial fashion.
2. The antheridium is the male gametophyte that carries sterile cells used to fertilize female's eggs. The archegonium is the female gametophyte that's function is to carry an egg; ready to be fertilized and turned into an embryo using the male's sperm.

4. The prothallus is the fern's gametophyte. It's very small and produces gametes to be used for fertilization.
