CELLS
All living things are made up of cells.
Cells are the basic structural unit of living things.
All cells come from preexisting cells.
Prophase
order 1.
Description:DNA condenses,nuclear membrane dissolves.
2 new cells produced during cycle
Daughter cells.
What specialization means and why it occurs.
Specialization means each specialized cell only exposes the genes necessary to carry out its job,after stem cells differentiate into specialized cells.Why:To carry out its job because we can often tell the function of cells based off shapes.
3 differences between plant and animal cells..
Animal:Small vacuoles, no cell wall. smooth circular shape.
Plant:Large vacuoles, cell wall,ridged edges.
Metaphase
Order 2
Description:chromosomes align at center of cell,spindle fibers attach to chromosomes.
What type of cells does mitosis occur in animals
Somatic/Body cells.
2 of the 3 factors that affect how a cell specializes.
1,Tatipotent:Embro,cell can became any cell in the human body.
2,Pluripotent:Stem cells that can become most cells in the human body.
3 Reasons cells must divide
To replace damaged or dead cells.
To allow new cells to reproduce and manage nutrients/water.
So organisms can reproduce larger and stronger for the cell.
Description:Chromatids pull to opposite poles,spindle fibers shorten.
2 reasons that cells would be signaled to stop dividing during cell cycle.
1, breakdown in chemical signaling, where cells fail to receive growth factors.
2, faulty DNA replication which can cause the cell to die on their own.
2 important things that occur during interphase during the cell cycle.
Cells grow to prepare for mitosis.
Centrioles are replicated,more organelles will form.
Telophase
Description:Nuclear membrane reforms,cell prepares to divide.
1,Why tumours form.2,What does it mean if they metastasize?
1,Tumours form because of cells building up that continue to divide without giving benefits to the body.
2,If they metastasize cancer cells will break from the tumour and spread to other parts of the body depending on which cancer you have.
What part of the cell divides during mitosis.
Chromosomes.
Interphase
Description:Cell grows and prepares for mitosis,centrioles get replaced by organelles.
What are 2 effects of cancer cells on the body.
1,Cancer cells can go deeper into the body's tissue.
2,Cancer cells invade other areas of the body.
