What are the two main types of cell - answerProkaryotic
Eukaryotic
Which cells are prokaryotic - answerBacteria
What cells are eukaryotic - answerPlant animal and fungal
What are the differences between the two types of cells - answerProkaryotic cells are smaller in size
Prokaryotic doesn't have a nucleus
The genetic material is in a single dna loop or small rings called plasmid
What are plasmids - answerLoops of dna that can be transferred from one cell to another
Where are proteins made in a cell - answerRibisomes
What is the function of the cell sap - answerSupports the plant
How do you calculate magnification - answerImage size
Over
Actual size
How may pairs of chromosomes do we have - answer23
What are the stages of mitosis - answerParent cells with two pairs of chromosomes
Each chromosome replicates
, Chromosomes line up I'm the centre and are pulled by spindle fibres to opposite poles
Genetically identical daughter cells
Why is mitosis important - answerBe aside it makes new cells for growth and development
Repairs damaged tissues
Asexual reproduction
What are stem cells - answerUndifferentiated cells they have not yet become specialised
Where are stem cells found? - answerHuman embryos, umbilical cord
What are stem cells found in human embryo called - answerEmbryonic stem cells
What type of cells can embryonic stem cells make - answerAll types of cells
We're are adult stem cells found - answerSome organs and tissues
What cells can adult stem cells make - answerThey can only make certain types of cells
Uses of stem cells - answerTreating conditions where cells are damaged or not working properly
Diabetes
Paralysis
Replace damaged cells
What is therapeutic cloning? - answerA cloned embryo of patient made and used as a source of stem
cells
