Prokaryote ◦ No nucleus ◦ Unicellular ◦ Example: Bacteria Eukaryote ◦ Nucleus ◦ Complex organelles ◦ Uni or multicellular ◦ Example: Us!
Responsible organelles ◦ Animal cell – mitochondria ◦ Plant cell – chloroplast It’s all about ATP ◦ Make it or break it
Cell membrane – controls what goes in and out ER – tubes for transport Lysosome – digestive enzymes Vacuole – temp. storage Mitochondria – energy! Golgi – repackage stuff Cytoplasm - fluid
Growth and division of cells IPMAT ◦ Interphase – 80% of the time – DNA copies ◦ Prophase ◦ Metaphase ◦ Anaphase ◦ Telophase
Process of cell division resulting in two identical cells (daughter cells) that are the same as the parent cell. Body cells are made.
Process of cell division in which four "daughter" cells are produced from one "parent" cell, each with half of the genes of the parent. Makes gametes or sex cells.
Mitosis – somatic cells Meiosis – makes sex cells (sperm & egg) ◦ AKA gametes ◦ Have a half-set of chromosomes (haploid) ◦ 2 cell divisions ◦ Makes 4 cells ◦ Same phases IPMATPMAT
Mitosis ◦ 1 cell division ◦ Daughter cells identical to parents cells ◦ Produces 2 cells ◦ 2n → 2n ◦ Produces cells for growth and repair ◦ No crossing over Meiosis ◦ 2 cell divisions ◦ Daughter cells different from parents ◦ Produces 4 cells ◦ 2n → 1n ◦ Produces gametes ◦ Crossing over
The movement of particles from high to low concentration Osmosis = water only Cell membrane responsible ◦ Semi-permeable Want to achieve homeostasis
DIPLOID Diploid = 2(n) In humans: n=23 chromosomes 2(n)= 46 total chromosomes 2 sets of each chromosomes Somatic cells are diploid Body Cells (nerve, muscle,

Cell Reproduction Meiosis Notes. Why does meiosis occur?
All cells come from pre-existing cells New cells are produced for growth and to replace damaged or old cells New cells are produced for growth and to.
CELL DIVISION Mitosis and Meiosis ASEXUAL (EUKARYOTES ONLY) SEXUAL I CAN: Compare the advantages of sexual reproduction and asexual reproduction in different.
Cells. Prokaryotic vs. Eukaryotic Cells Prokaryotic cells: These do NOT have a nucleus or membrane-bound organelles. Only bacteria are prokaryotic.
Cell Division Mitosis and Meiosis. The Cell Cycle Mitosis Interphase.
How Cells Divide Chapter Cell Division *growth and repair *reproduction.
Chapter 8 Notes. Mitosis Cells must divide: 1.to keep the surface to volume ratio manageable 2.because if cells get too large, they can not eliminate.
Question 1 The spindle fiber is made of proteins. What elements are present in proteins? C, H, O, N, S.
Cell Cycle & Cell Division. Cell Cycle
Meiosis 10/29/09. What can you tell me about Mitosis?
The Cell Cycle & Cell Division. The Cell Cycle
M Phase (division) Interphase G1 Phase G2 Phase S Phase Growth DNA & Chromosome Replication Cells Spend Most of the Time in Interphase.
All Cells have…. Ribosomes - make protein for use by the organism. Cytoplasm - jelly-like goo on the inside of the cell DNA - genetic material Cytoskeleton.
The Human (Animal) Cell. Cell Membrane Responsible for controlling what substances go into and out of the cell Think of a screen door…
