Interphase: is the stage in the development of a cell following mitosis or meiosis, during which the nucleus is not dividing.
My own definition: Interphase is where the cell prepare for mitosis.
Sentence: The phases in interphase are called G1, S and G2 phase.
​
Prophase: the first stage of cell division, before metaphase, during which the chromosomes become visible as paired chromatids and the nuclear envelope disappears. The first prophase of meiosis includes the reduction division.
My own definition: Prophase is where the nucleus start degrading (because it leaves DNA) and the centrioles go to poles.
Sentence: Prophase is the first step of mitosis.
​
Metaphase: the second stage of cell division, between prophase and anaphase, during which the chromosomes become attached to the spindle fibres.
My own definition: Metaphase is where the spindle fibres attach to the sister chromatids and at the same time moving to the centre.
Sentence: Metaphase is the second step of mitosis.
​
Cytokinesis: The cytoplasmic division of a cell at the end of mitosis or meiosis, bringing about the separation into two daughter cells.
My own definition: Cytokinesis is when the cell divides into two cells.
Sentence: Cytokinesis is the final phase of the cell cycle.
​
Chromatid: Each of the two threadlike strands into which a chromosome divides longitudinally during cell division. Each contains a double helix of DNA.
My own definition: Chromatids are duplicated chromosomes.
Sentence: The chromosomes turn into sister chromatids in the S phase.
​
G1 phase: the first growth period of the cell cycle, during interphase, in which the cell grows and cytoplasmic organelles are replicated.
S phase: the period of the cell cycle prior to mitosis, during which the chromosomes are replicated.
G2 phase: the second growth period of the cell cycle, following DNA replication and preceding prophase, during which the cell forms the materials that make up the spindle.
​
My own definition
G1: the phase where normal cell activity happens.
S: where DNA synthesis happens, it is where the chromosomes duplicate and becomes sister chromatids.
G2: where the cell membrane becomes bigger so when the cell divides, the daughter cell will be regular size.
​
Sentence: G1, S and G2 phase are all before mitosis.
Anaphase: the stage of meiotic or mitotic cell division in which the chromosomes move away from one another to opposite poles of the spindle.
My own definition: Anaphase is where the spindle fibre is pulling apart the sister chromatids.
Sentence: Anaphase is the third step of mitosis.
​
Telophase: the final phase of cell division, between anaphase and interphase, in which the chromatids or chromosomes move to opposite ends of the cell and two nuclei are formed.
My own definition: Telophase is where the chromatin starts moving becoming DNA, two nucleus forms and a cleavage forms.
Sentence: Telophase is the last step of mitosis.
​
Chromosome: A threadlike structure of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes.
My own definition: Chromosome are DNAs forming a structure that looks like a thread.
Sentence: Humans have 23 identical pairs of chromosomes.
​
Centriole: Each of a pair of minute cylindrical organelles near the nucleus in animal cells, involved in the development of spindle fibres in cell division.
My own definition: Centriole is an organelle that produces spindle fibres.
Sentence: Centriole produces spindle fibres that helps attach to the sister chromatids in the metaphase.
