Cell Division Flashcards
How do body cells divide
Mitosis which is the splitting of chromosomes
What do chromosomes contain
Genetic information
What is mitosis
Copies of the genetic material are made
Cell divides once to form two genetically identical body cells
When does mitosis occur
During growth or to produce replacement cells
What is the difference to a body’s cell chromosomes and gametes chromosome
Body cell = two sets/ one pair
Gamete = one set
What do cells in reproductive organs do
Divide to form gametes
What is meiosis
Type of cell division in which a cell divides to form gametes
What is the cell division when a baby is conceived
When gametes join it is meioses as a single body cell with new pairs of chromosomes is formed
Then cell develops and repeatedly divides by mitosis
How are animal and plant cells different in terms of differentiation
Animal cells differentiate at and early age
Plant cells remain unspecialised all through their life
What is mitosis used for in mature animals
Mainly for repair and replacement
What cells are unspecialised in human cells and what can they be used for
Human embryos and adult bone marrow
Made into different types of cells e.g. Nerve cells
What do human stem cells have the ability to do
Develop into any kind of human cell
What conditions can treatment with stem cells help with
Paralysis
What type of cell division does asexual reproduction do
Mitosis from parental cell thus identical
