Zygote
A zygote is the initial cell that forms when two gametes (sperm and egg) fuse during fertilization. It is the starting point of a new organism and contains a complete set of chromosomes, half from the mother and half from the father. The zygote undergoes a series of divisions through the process of mitosis to develop into a multicellular organism.
Key Points to Remember:
- The zygote is formed when a sperm cell fertilizes an egg cell.
- It contains a complete set of chromosomes, half from the mother and half from the father.
- The process of cell division (mitosis) allows the zygote to develop into a multicellular organism.
- Genetic information from both parents is combined in the zygote, determining the traits and characteristics of the new organism.
Study Guide Questions:
- What is a zygote and how is it formed?
- What is the role of mitosis in the development of a zygote?
- How does the genetic information from both parents contribute to the traits of the zygote?
- What are the key characteristics of a zygote?

Ecosystems: Interactions, Energy, and Dynamics
Use evidence and scientific reasoning to explain how characteristic animal behaviors (e.g., building nests to protect young from cold, herding to protect young from predators, attracting mates for breeding by producing special sounds and displaying colorful plumage, transferring pollen or seeds to create conditions for seed germination and growth) and specialized plant structures (e.g., flower brightness, nectar, and odor attracting birds that transfer pollen; hard outer shells on seeds providing protection prior to germination) affect the probability of successful reproduction of both animals and plants.
