Unit 4 Cells to Organisms
Probe Questions and Answers
Cells and Size~If you can see it with your eyes it is bigger than a cell.
Whale and Shrew~No matter how much bigger the animal, plant, or person is cells are ruffly the same size just some have more than others.
Sam's Puppy~Cells don't grow bigger they multiply and increase in number.
DNA
The 3 Parts of Nucleotide: (1)Phosphate (2)Deoxyribose (3)Nitrogenous Base
Nucleosides: Adenine/Thymine & Cytosine/Guanine
Meiosis Vs Mitosis:
Interphase is Growth, DNA reproduction, and general cell process
When you combine the sperm(23) and egg(23) it make 46 chromisones
Meiosis creates egg and sperm cells
Meiosis has only 23 while mitosis has 46 chromisones
Meiosis is sexual redropuction
Mitosis is asexual reproduction
Remember the handshake
Cytokinesis is the reason the cells split after PMAT
PMAT: prophase, metaphase/middle, anaphase/away, telophase/two
Mitosis produces identical DNA
Homologous means about the same
Cross over shares DNA information
Somatic cells can't go through meiosis
Sperm cells and egg cells are gametes
