By the end of today, SWBAT…

MASTER the four cellular processes!

Kick Ms. Stroh’s butt tomorrow!

Review

Our first topic is…

Photosynthesis and cellular respiration!!!

Photosynthesis and Cellular Respiration

6CO2 + 6H2O + sunlight C6H12O6 + 6O2

C6H12O6 + 6O2 6CO2 + 6H2O + ATP

Photosynthesis

Cellular Respiration

Glucose + Oxygen

Water + Carbon Dioxide

Energy (ATP)

6CO2 + 6H2O + sunlight C6H12O6 + 6O2

C6H12O6 + 6O2 6CO2 + 6H2O + ATP

Review

Our second topic is…

Phases of mitosis and meiosis!!!

Cell Phases

InterphaseProphaseMetaphaseAnaphaseTelophase

Cell Phases – Mitosis

Interphase: Time in between cell divisions.At end of interphase,

chromosomes double.

Prophase:

Sister chromatids (the duplicated chromosomes) attach to one another.

Metaphase:

Sister chromatids line up in the center of cell (called the metaphase plate)

Time in between cell divisions. Telophase:

Anaphase:

Spindles pull sister chromatids apart, to opposite ends of the cell.

Cleavage furrow forms, “pinching” cell in half

Interphase:

Cell Phases – Meiosis

Meiosis has two parts Meiosis 1: genetic information switched,

cells divide Meiosis 2: cells divide ONE MORE TIME

Choices

Your classwork grade today is based on you completing one of the following:1. A foldable about mitosis, meiosis, or

their differences2. A poem/rap song about the phases of

mitosis

3. 8 possible test questions (with answers!) that you will present to the class

Review

Our third topic is…

Products of mitosis and meiosis!!!

Mitosis

Mitosis goes through PMAT one time. Therefore, it produces two cells. Each of these cells is exactly the same.

Since all somatic cells are 2N, and the cells produced by mitosis are exactly the same as the original cell, the cells produced by mitosis are 2N.

Meiosis

Meiosis goes through PMAT two times. Therefore, it produces four cells. Each of these cells is different.

Each gamete is different because in meiosis 1 some genetic information gets switched between chromosomes. This is why you do not look exactly like your relatives.

Each gamete has half as much DNA as the original germ cell. So, each cell is only 1N.

And a final message from Ms. Stroh’s class…

Review Packet

If you completed half of the review packet last night… Good work! You get an answer key! Check your answers, and ask me questions.

If you did not complete half of the review packet last night… You can work on it now, and ask me

questions. No answer key, sorry. Do your work next

time.
