I am stuck on this question that is on the study guide for my final. Could someone please help me with this?
3. The evolutionary success of each species of organism depends on its ability to reproduce. Some species reproduce sexually, others reproduce asexually. Some species reproduce sexually at one stage of their life cycle, and asexually at another stage.
A. Describe the cells involved in sexual reproduction and explain the process through which these cells are produced (meiosis).
B. Describe three types of asexual reproduction.
C. Identify an organism that has both sexual and asexual reproductive stages. Describe the structures involved in producing the reproductive cells for each stage, and explain how these cells interact.

I'm working on a review sheet for this too! anyway...
A.Gametes are used in sexual reproduction. Reproduction division divides the homologous pairs so it reduces by chromosme # to1/2. chromatids remain attached. then, normal division divides the replicated chromosomes into chromatids so chromosome# stays the same.
B.Asexual reproduction is like, buds off of an old potatoe, or a worm can grow back if some of it is cut off, or a starfish can re-grow itself as well. It just requires 1 parent & the offspring is an exact copy of the parent.
*Hope that answers your questions...
