Oreo Cookie Mitosis Lab Activity

Oreo Cookie Mitosis Lab
The Cell Cycle
The process of Mitosis will be illustrated through the cookies with cream filling.
Materials Needed:
- Oreo Cookies 6
- Sprinkles of various colors
- Toothpicks
- Paper towels
Procedure:
The top of the cookies will be twisted so that we can get the cookie with cream. The cream cookie will look as cytoplasm and the sprinkles will look like the organelles which are needed for the process of Mitosis.
Interphase
Interphase
Interphase is a crucial stage in the eukaryotic cell cycle, preparing the cell for division. Interphase is the longest stage in the eukaryotic cell cycle, occurring between the end of one mitosis and the beginning of the next. It is divided into three distinct phases: Gap 1 (G1), Synthesis (S), and Gap 2 (G2)During interphase, the cell acquires nutrients, grows, replicates its DNA, and carries out other "normal" cell functions.
Prophase
Prophase
Prophase is the earliest and longest phase of mitosis, during which the nuclear membrane separates, disclosing the cell's chromosomes. The two identical chromosomes connected by the centromere are known as chromatids because they have the same genetic makeup. This phase ensures that the correct amount of genetic material is distributed to identical cells by compressing and organizing the genetic material, rupturing the nuclear membrane, and generating spindle fibers.
Metaphase
The second stage of mitosis, which comes after prophase and before anaphase, is known as metaphase. It involves the equator-centered alignment of duplicated chromosomes, which is made possible by spindle fibres. This ensures even distribution to daughter cells in anaphase.
Anaphase
The third stage of cell division in mitosis, following metaphase, is known as anaphase. It involves pulling sister chromatids apart and moving them towards opposite poles. This division maintains genetic stability by guaranteeing identical chromosomes for each daughter cell.
Telophase
Telophase
The final stage of cell division, known as telophase, is when the nuclear membrane fragments come together, the mitotic spindle divides, and the chromosomes reach the cell poles. In order to prepare newly produced cells for specific reasons, it requires cytokinesis, identical cell division, nuclei growth, and nuclear membrane changes.
Cytokinesis
Cytokinesis
Cytokinesis is the physical process of cell division, following the separation of the nucleus, in which the cytoplasm of a parental cell is divided into two daughter cells. Each daughter cell has its own nucleus, cytoplasm, organelles, etc. Each daughter cell now begins their own cycle starting from interphase.
