Your HDA Hopes, Dreams, and Aspirations

Your 10 Year Goals 10 years from today Where will you live? What will

Your 10 Year Goals 10 years from today Where will you live? What will you be doing? Things to think about; will you have a job? Will you be in college? Will you have graduated and start a career? Will you have moved? House or apartment? Roomates? Consider everything.

Considering those goals you set. . . What are you doing RIGHT NOW to

Considering those goals you set. . . What are you doing RIGHT NOW to prepare for those goals? Are you studying for SAT’s? Do you have a part time job? Do you know which colleges you’re thinking of applying to? Are you planning on entering your career straight out of high school?

What still needs to be done…? What things are you NOT doing right now

What still needs to be done…? What things are you NOT doing right now that still need to happen? Create a list. 1. Apply to part time jobs 2. Get driver’s license 3. Get CAR to drive 4. etc.

Describe your move out day Let’s assume you’re moving out of your parents house

Describe your move out day Let’s assume you’re moving out of your parents house at some point in these 10 years. Describe that day. What happens? Be as detailed as possible.

Overview 1. Cell division happens in the body cells, called SOMATIC CELLS 2. The CELL CYCLE is the series of events that the cell goes through as they grow and divide. 3. Both PLANT AND ANIMAL cells undergo the cell cycle and mitosis. 4. It maintains the SAME genetic information from one cell to the next. Remember when you copied your K’NEX DNA?

Stages Two Main Phases Interphase (90%) and Mitosis (10%)

Stages Two Main Phases Interphase (90%) and Mitosis (10%)

G 1 -Gap 1 The cell grows LARGER, makes new proteins, and develops organelles.

G 1 -Gap 1 The cell grows LARGER, makes new proteins, and develops organelles. Like you, since you were little, people have asked what you want to be when you “grow up”. Since you were tiny, you’ve been growing and maturing.

S (Synthesis) Synthesis is when the DNA in your cells begins to replicate. Or

S (Synthesis) Synthesis is when the DNA in your cells begins to replicate. Or making copies of the DNA…. . . preparing for what is ahead. It’s like you, now, preparing for your future. As you are going through your daily life, what are you doing to prepare to live on your own?

G 2 Last phase before cell enters mitosis. The cell grows more and produces

G 2 Last phase before cell enters mitosis. The cell grows more and produces structures needed for upcoming division. When you’re ready to split from home. . . what do you need to have ready for moving day? (electricity turned on, helpers)

Mitosis Shortest Phase of the cycle, but greatest amount of activity. Everything has been

Mitosis Shortest Phase of the cycle, but greatest amount of activity. Everything has been leading up to this moment. It’s time to split! This is like, “moving day”.

Why do cells undergo mitosis? 1. To replace old cells 2. To replace damaged

Why do cells undergo mitosis? 1. To replace old cells 2. To replace damaged cells 3. To allow the organism to grow in size. Mitosis divides the nucleus, distributing DNA to each daughter cell. It is an EXACT COPY of itself. Like your K’nex split into two copies!

Mitosis It is completed by cytokinesis, which divides the cytoplasm and separates the cell

Mitosis It is completed by cytokinesis, which divides the cytoplasm and separates the cell into two individual cells (daughter cells)

A word about cancer…. When cells leave the cell cycle, they exit the G

A word about cancer…. When cells leave the cell cycle, they exit the G 1 phase and then go into a resting period called a G 0 phase…. Most cells then go back to a G 1 phase and then to the S phase. Cancer cells are different because they don’t enter a G 0 phase, and are then likely to repeat the cell cycle continuously (causing overproduction of cells or tumors).

What is the difference between the cell cycles of cancer and a regular cell?

RECAP 1 G 1 -daughter cell grows up 2. S(synthesize)-prepares for future by replicating

RECAP 1 G 1 -daughter cell grows up 2. S(synthesize)-prepares for future by replicating DNA 3. G 2 -doubles in volume, produces organelles to help it split. 90% of time is spent in the phases G 1, S, and G 2. 10% of time is spent in 4. M(mitosis)-cell splits into daughter cells. mitosis.

Don’t answer this out loud, just think about it in your head. If you

Don’t answer this out loud, just think about it in your head. If you were to examine a plant or an animal cell under a microscope, what phase of the cell cycle would you most likely see? Why?

Let’s see what you remember. . . Which phase has the most DNA…. .

Let’s see what you remember. . . Which phase has the most DNA…. . G 1, S, G 2, or M?

Cell Cycle Plate G 1 1. Divide your plates into 4 sections 2. Label one section G 1, another S, then G 2, and finally M. MOVE CLOCKWISE! 3. Define each stage in your own words 4. Illustrate what the cell is doing in each stage M S G 2
