Q
Volvox spp.
A
- Are colonial living organisms
- Show us the first instance of cell differentiation
- Within colonies, different cells have different jobs (some reproduce, so move the colony)
- When moving colony, a group of Volvox individuals act as one large, multicellular individual

- Daughter colonies
12
Q
How do live and present volvex slides reproduce?
A
- Sexually
- Asexually
13
Q
Sexual Reproduction
A
- formation of macrogametes (oocytes) and microgametes
(spermatocytes)
14
Q
Asexual Reproduction
A
- formation of daughter colonies (genetically identical clones ofthe mother colony)
15
