Study Notes
Reproduction in Living Organisms
- Reproduction is a fundamental characteristic of all living organisms.
- Reproduction can occur asexually in unicellular organisms or sexually in multicellular organisms.
- Sexual reproduction involves the fusion of two gametes (sex cells) to form a zygote.
- The zygote is a fertilized egg cell that develops into a new organism.
Cell Division
- All cells originate from pre-existing cells through a process known as cell division.
- In prokaryotes, cell division occurs through binary fission, a simple process where the cell replicates its DNA and divides into two identical daughter cells.
- Eukaryotic cell division is more complex and occurs in two distinct phases: interphase and the mitotic phase.
