Mitosis & Cell Parts Flashcards
Chromosomes begin to be visible under a light microscope.
Prophase
The nucleolus and the nuclear membrane disappears.
Prophase
The spindle fibers attach to one side of each centromere.
Prophase
The longest stage in mitosis.
Prophase
The spindle fibers begin to form and extend into the cell from the centrioles that moved to opposite sides of the cell.
Prophase
Third phase of mitosis.
Anaphase
The centromeres seperate.
Anaphase
The spindle fibers begin to contract and shrink and they move towards the opposite sides of the cell.
Anaphase
The spindle fibers pull the doubles stranded chromosomes into a line that passes through the cell in the center.
Metaphase
Chromosomes are now completely visible under an optic microscope.
Metaphase
A complete set of chromosomes is now at each pole of the cell. The spindle fibers begin to disappear. The nuclear membrane begins to form.
Telophase
There are two nucleus in a single cell, and the cell is ready to divide.
Telophase
An equatorial plaque develops in the center of the plant cell which creates a new cell wall between the two new cells.
Telophase
_____ ensures that every new cell that is made receives the same genetic material, DNA (deoxyribonucleic acid) as the old one.
Mitosis
The process of cell division is called ______
Mitosis
Chromosomes are joined in the middle by a ______
Centromere
The arms and legs of chromosome are called ______
Telomeres
Chromatin coils up to make double stranded ______
Chromosomes
The part of the cell cycle where the cell spends most of it’s life in is _____
Interphase`
Before mitosis can begin, the nucleus must make a copy of each strand of chromatin(DNA).
Interphase
The cell grows, replicates its DNA and prepares for cell division.
Interphase
The division of the cytoplasms to form two daughter cells.
Cytokinesis
The cell mebrane of the cell contracts in the center and divides into two new cells.
Cytokinesis
What’s the 3 principles of the cell theory?
All living things are made up of cells.
Cells are the smallest working units of all
living things.
All cells come from preexisting cells
through cell division.
A _____ is the smallest unit that is
capable of performing life
functions.
cell
What are the two types of cells?
Prokaryotic & Eukaryotic
What type of cell do NOT have structures surrounded by membranes, only has a few internal structures, and are One-celled organisms?
Prokaryotic
What type of cell contain organelles surrounded by membranes, makes up most living organisms?
Eukaryotic
