MONDAY-9/25...GO TO CH 5 NOW- TISSUES
Podcast 1-Ch 3 Mitosis...Listen to this podcast and download it top your devices for review and remediation on assessments...

Podcast 1-Ch 3-Mitosis (2).MP3

Thursday-9/21...CW: Mitosis: Cell division of Nucleus...
2 videos: watch this one:  https://youtu.be/f-ldPgEfAHI
 and tomorrow will be this one...
https://youtu.be/lpAa4TWjHQ4
THIS IS CONSIDERED HOMEWORK, WHICH IS A COUNTY REQUISITE OF 30 MINUTES of HW EACH DAY...

Mnemonic: I-P-M-A-T...The 4 stages of Mitosis is PMAT...The I is not one of the 4  Mitosis stages but is the LONGEST!!
Friday-9/22...CW: CH 1-2-3 Summative test today-33Q = 100 pts...
HW: always review day's lesson in text and check webpage...

Wednesday-9/20...CW: You learned about pH in ch 2 and now begin Ch 3-Cells...Most of the information has been taught in Biology but some prior knowledge must be reviewed for further understanding of our 11 body systems soon to follow...
***Remember the Levels of organization previously discussed...
***NUCLEUS: brain of the cell...
***ORGANELLES: structures within the cell...
***MITOCHONDRIA:poswerhouse of the cell(ATP)...
***CELL(PLASMA) MEMBRANE: allows for DIFFUSION(air) and OSMOSIS(H2O)...
***CHROMOSOMES: 23(prs) = 46...XX = female, XY = male
***CANCER: uncontrollable growth and division of cells...

Mitosis Vocabulary

Mitosis –the process of cell division including division of the nucleus.

Cancer –disorder caused when cells lose the ability to control growth and continue to divide.

Interphase –part of the cell cycle when the cell is not dividing

G1 –phase of the cell cycle after cell division, growth and day to day life of a cell.

S Phase –Replication or synthesis of DNA and associated proteins that happens before cells divide.

G2 –Phase of the cell cycle when cells prepare for cell division by making more organelles and cytoplasm.

Diffusion – How most water soluble materials get into a cell.  process by which molecules tend to move from an area of higher concentration to an area of lower concentration.

Chromosome –Thread like structure with in the nucleus containing genetic information. Made of DNA coiled around proteins.

Chromatid –half of a duplicated chromosome.  One of two “sister” parts, makes half of the “X”(middle is Centromere)

Centromere –area where sister chromatids of a chromosome attach.

Cell Cycle –series of events cells go through when they divide.

Prophase – when the chromosomes coil up and become visible, and the centrioles go to opposite sides of the cell.

Centriole –tiny microtubule structure located in the cytoplasm that helps create the spindle fibers.

Spindle –helps separate the chromosomes during mitosis. Fan shaped structure made of microtubules.

Metaphase –when chromosomes line up in the middle of the cell , during cell division.

Anaphase –when the chromosomes pair separates and moves toward opposite sides, third phase of mitosis.

The Cell Cycle - How do cells reproduce?


What is cell division?
  • Process by which new cells are produced from one cell.
  • Results are 2 cells that are identical to the original parent cell.
Why do cells divide?
  • To replace other cells that have been damaged or worn out
  • To allow multicellular organisms to grow
  • For asexual reproduction
  • Because they get too big!
What is MITOSIS?
  • Mitosis is the process in which one cell DIVIDES to make two new cells
  • Each cell has the SAME genetic material as the original cell
  • Its like “photocopying” the cell- They are IDENTICAL
  • Genetic Information
    • Genetic information is contained in the DNA of the cell
    • DNA is found in long fibers called CHROMATIN
    • Each long fiber makes up a CHROMSOME
