What are some examples of body cells

 

 

 

Definition

Skin cells, liver cell, kidney cells

Term
what are body cells produced by
Definition
 asexual reproduction
Term
In body cells how many parents is it?
Definition
One
Term

In the body cells what is the DNA to the parents

Definition
Identical
Term
what comes from the body cells
Definition
Mitosis
Term
[1] go through stages, or a life cycle, while they are a live? What are the life cycle[2]
Definition

[1] Organisms

[2] birth,grow,developement, dealth

Term

The majority of its life is spent in the

Definition
growth and developement stage
Term
How does an organism grow?
Definition

greater size of the cells and greater number in cells

Term
what also have a life cycle
Definition
cells
Term
In a cell this is called_ when the cell increases in size
Definition
Intertphase
Term
To increase in_the cells must enter the cells division phase celled_
Definition

[1] number

[2] mitosis

Term
the _ can help us to understand these phases of cell life 
Definition
cell cycle
Term
What is Interphase?
Definition
  • cell grows to its full size
  • prepares to mitosis by copying its centrioles and DNA
  • DNA is in the form of long thin chromatin
Term
What is Prophase
Definition
  • Replicated chromatin thicness and shortens into chromosomes[becomes visable] each chromosomes is made up of 2 sister chromatids that are conected by centromere
  • Nuclear membrane breaks down
  • Centromere travels to opposite ends of the cell
  • Spindle fibers form between the centromere  
Term
What is Metaphse
Definition
  • chromosomes line up across the center of the cell
  • Each chromosomes attaches to a spindle fiber at its centromere 
Term

What is Anaphase

Definition
  • Centromere of each chrosomsome splits
  • Sister chromatids separate to oppostie ends of the cell, along the spindle fiber
  • Cell streched out as opposite ends pull
Term

What is Telophase

 

Definition
  • Nuclear membrane reforms around each group of chromosomes
  • Chromsomes [DNA] unwinds to chromatin once again
  • Centrioles and spindle fibers disappear
Term
In__ the cell cycle, the cytoplasm divides in the process of _
Definition

[1] Stage 3

[2] Cytokinesis

Term
What is Cytokinesis
Definition
  • Cell membrane pinches in around the middle of the cell, untill 2 daughter cells are formed [plant cells do cell plate formation due to the cell wall]
  • each daughter cells DNA is identical to the parent cell
Term

In __of the cell cycle, the nucleus divides in the process of __

 

Definition

[1] stage 2

[2] Mitosis

Term
In __ of the cell cycle, the cell is in __
Definition

[1] Stage 1

[2] Interphase

Term
what is the 1 stage
Definition
Interphase
Term
what is stage 2
Definition
Prophase
Term
what is the 4 stage
Definition
anaphase
Term
what is the 6 stage
Definition
Cytokinesis
Term

what is the 5 stage

Definition
Telophase
Term
what is the 3 stage
Definition
Metaphase
Term
when is it when the spindle fiber catch on to the centromere 
Definition
Metaphase
Term
when is it when the centrioles disappear
Definition

Telophase

Term
when is it when the chromosomes unwind to chromatin
Definition
Telophase
Term
when is it when the neclear membrane breaks down
Definition
Prophase
Term
when is it when the cell stretches out as oppsite ends pull
Definition
Anaphase
Term
when is it when the sister chromatids separate to opposite ends of the cell along the spindle fiber
Definition
Anaphase
Term

when is it when the DNA is in the form of long thin chromatin

Definition
Interphase
Term
when is it when the each daughter cell's DNA is identical to the parent cell
Definition
Cytokinesis
Term
when is it when the nuclearmembrane reforms around each group of chromosomes
Definition
Telophase
Term
when is it when the spindle fiber forms between the centromere
Definition
Prophase
Term
