introduction
directions: read the introduction and watch the video below. then answer the essential question to
the best of your ability. you will revisit it at the end of the module to see if your answer has evolved.
cells are the basic units of life and their ability to reproduce, grow, and differentiate is fundamental to
the existence of multicellular organisms. the cell cycle, mitosis, and cell differentiation are integral
processes that ensure the proper functioning and development of tissues and organs.
the cell cycle describes the series of events that cells undergo as they grow and divide to produce two
daughter cells. the cycle includes interphase, where cells prepare for division by duplicating its dna
and organelles and mitosis the division phase of the cell cycle.
watch the following video to view an actual bacterial cells going through cell division.

essential question
life begins as a single cell called a zygote. explain how a single cell can become a newborn baby.

Explanation:

The zygote undergoes cell division (mitosis) to increase the number of cells. Through the cell cycle, it duplicates DNA and organelles. Then, cell differentiation occurs, where cells become specialized. These processes lead to the formation of tissues and organs, eventually resulting in a newborn baby.

Answer:

A single - celled zygote becomes a newborn baby through cell division (mitosis) which increases cell number, the cell cycle (including DNA and organelle duplication), and cell differentiation (to form specialized cells, tissues, and organs).
