Cells and DNA Flashcards
Name all the Cells in an Animal Cell.
Nucleus, Cytoplasm, Cell Membrane, Mitochondria, Ribosome.
Name all the Cells in a Plant Cell.
Nucleus, Cytoplasm, Cell Membrane, Mitochondria, Vacuole, Ribosomes, Cell Wall
What is a Eukaryotic Cell.
A Eukaryotic Cell is a Cell with its DNA in the Nucleus .
What is a Prokaryotic Cell.
A Cell with its DNA is not in a Nucleus.
Where is Bacteria’s DNA Located.
In Plasmids ; Ring of DNA
What is Mitosis.
Mitosis is the process of which Cells are made, they divide the chromosomes that contain the DNA, they are copied, and they all line up in the middle of cell and then they are separated.
How many Chromosomes do Humans Have?
Humans have 23 Pairs of Chromosomes. That’s 46 in total. Every Cell have these.
What type of Cell does not have 23 Chromosomes?
Gametes (Sex Cells), Sperm and Egg Cells have 23, not 46.
What is Meiosis
Meiosis is how Gametes are made.
Why do Sperm and Egg Cells only have Half the Information?
Because in Fertilization they Join together to make a full set
How many Pairs do Diploid Cells have?
In your Ovaries, or Testes, they have 23 pairs
After Fertilization is complete, what do you end up with?
Stem Cells, but then they become specialised, meaning they have a specific job; Brain Cells, Cheek Cells etc.
What do Stem Cells go on to do.
Make Tissue such as; Heart Tissue, Lung Tissue, and if you have lots of tissues together, they make an organ.
