Chapter5 Cell Cycle/Differentiation Flashcards
What happens in stage 1 of the cell cycle?
Cell gets bigger and replicates the DNA and creates 2 copies from both chromosomes. And increases sub-cellular for mitochondria and ribosomes and clororplasts.
What happens in stage 2 of the cell cycle?
Mitosis and chromosomes pulls each end after cell and nucleus divide.
What happens in stage 3 of the cell cycle?
Cytoplasm and cell membrane divides into 2 after it is 2 identical daughters/sons cells.
Why is misosis important?
Misosis is the division of cells into 2 identical cells. All cells need to be identical so as to allow growth. New cells are required to replace any damaged ones. Mitosis is also important when reproduction takes place without a partner. This is also known as asexual reproduction.
What are the stages of Differentiation?
First it fertilised the egg to make this its calles mitosis. The second stage stem cells are in the embryo. These cells can become any type of cell.
What happens at the last stage of differentiation?
Cells become specialised to carry out jobs. And that they carry out functions and have particular structures.
In what ways is differentiation in plants different to animals?
Animal and plant cells are different. Animals cells cannot differentiate as once the cell is specialised it cannot be changed. Plant cells are able to change from one specialist cell to another known as redifferentiation.
