1 What protein regulates the cell cycle? Cyclin
2 In which phase of mitosis are the chromosomes split in half? Anaphase
3 Name the 5 phases of the M-phase! Prophase, Metaphase, Anaphase, Telephase, and Cytokenisis
4 Define apoptosis and give an example. Programmed cell death (such as the space between your toes)
5 Two chromotids are connected in the middle by the __________. Centromere
6 If a cell enters Interphase with 6 chromatids – how many chromatids will it have during metaphase?– 12 chromatids
7 During the cell cycle how do you know if its an animal cell or a plant cell? Plant cell forms a cell plate during cytokinesis
8 When do chromosomes first appear in the cell cycle? Prophase
9 What is an advantage of asexual reproduction? Rapid growth
10 What is the function of the centriole? Organize the Spindle fibers
11 During which stage of mitosis do the spindle fibers attach to the centromere? Metaphase
12 Programmed Cell death is called ________. Apoptosis
13 In eukaryotic cells, what do cyclins do? Regulate the timing of the cell cycle.
14 Embryonic stem cells are found in _____________ cells. Pluripotent Pluripotent Multipotent Multipotent Totipotent Totipotent Simplepotent Simplepotent Pluripotent
15 Why does cancer happen? Cells have lost their ability to to control cell growth.
16 In normal cells what causes cells to stop dividing? Growth factors or external regulators (when they are surrounded by other cells)
17 Mitosis and Cytokinesis are the only phases of the ____________. M-phase
18 Stem cell research is controversial when cells from the _______________ are used. Embryonic or pluripotent cells
19 What causes cancer cells to metastasize? Move into the blood stream and spread.
20 What ratio of surface area to volume is best for cells? 6:1, 3:1, or 2:1? 6:1
21 If the volume of the cell is too large, what will happen to it’s waste? The waste will be too large to find ways out of the cell – waste will build up.
22 When is demand on the DNA too great to function properly? When surface area to volume ratio is too small.
23 In which phase does the cell experience the most growth? G1G1
24 In prokaryote cells, how are cells replicated? From 1 parent cell dividing into 2 identical cells
25 What is the shortest phase of mitosis? Metaphase
List the four phases of mitosis in order
Ch 8.2 Cell Growth and Reproduction Learning about Asexual and Sexual reproduction of Cells.
The larger a cell becomes, the more demands it places on its DNA & the less efficient it is at moving nutrients/wastes Enough DNA = abundant cell.

The Cell Cycle & Cell Division
Mitosis How do your cells divide? Chapter 10 Why Do Cells Divide? Surface area Damaged cells Sex cells.
Ch. 10 Review.
Limits to Cell Growth Why do cells divide rather than continuing to grow indefinitely? The larger a cell becomes, the more demands the cell places on.
Cell Division and Reproduction. Before a cell becomes too large, it divides forming 2 “daughter” cells. This process is called cell division. It keeps.
Cell Growth and Division Chapter 10. Why are cells so small? DNA DNA –Messages from the nucleus must be able to reach all parts of the cell Diffusion.
Biology Unit 5 Exam.
Cell Division Ch. 10. Why do cells divide? (1) Exchanging materials The larger a cell becomes, the harder it is to get enough materials and waste across.
Cell Cycle: Mitosis Cell Growth and Division. Mitosis In asexual reproduction, one parent produces genetically identical offspring by mitosis. A life.
What Limits a Cell’s Size? 1. DNA content if cell is too large, DNA can’t control all of it 2. Diffusion Is efficient only over short distances – big.
Cell Growth and Division Chapter 5 Mr. Scott. Cell Growth Limits to cell growth Limits to cell growth The bigger a cell is, the more demands the cell.
Warm-Up 11/15/10 LIST the Phases of the Cell Cycle. Which Phase of the CELL CYCLE includes Prophase, Telophase, Anaphase, Metaphase? Put the Above-mentioned.
Cell Division #1 JEOPARDY S2C06 Jeopardy Review What Phase Is it? Vocabulary Cell Division Picture ID More Vocab
Cell Growth and Division Cell Growth Living things grow chiefly because of two things. 1. The number of cells increases.
Ch. 10 Cell Growth and Division. Chapter 10 Outline 10-1: Cell Growth –Limits to Cell Growth –Division of the Cell 10-2: Cell Division –Chromosomes –The.
Cell Growth and Reproduction
Cell Division. Chromosomes Are made of DNA Each chromosome consists of sister chromatids attached at a centromere.
Name 2 limitations to cell growth. How does DNA limit cell growth?
THE CELL THEORY All living things are composed of cells. Cells are the basic units of structure and function in living things. New cells are produced.
Cell Division Chapter 10.
MITOSIS. Animated Cycle
Cell Cycle and Mitosis. 1.Identify and summarise what happens in each phase of the cell cycle. 2.In G2 protein synthesis occurs to prepare the cell for.
Cell Cycle, Mitosis, and Meiosis
Review What is the cell cycle? What are the two stages of the cell cycle? Why do cells need to divide?
CELL CYCLE How many cells do we begin with? 2 How do we get more?
Chapter 10 A – Cell Growth and Division
Cell Reproduction. Why Cells Divide Cell death Repair of injury Growth/development Maintains cell size.
Cells divide during mitosis and cytokinesis. Cells that make up the “body” of an organism 2.
Chapter 10 Cell division Review. This spot that holds the 2 chromatid copies together is called a ________ CENTROMERE.
Chapter 10 Cell Growth Cell Growth Living things grow by producing more cells. Cells of an adult are the same size as the cells of a baby, adults.
Cell Growth and Division Why Cells Divide DNA overload Small cell – information stored in DNA meets all the cells needs Cell growth without limits leads.
Chapter 10. Limits to Cell Size ◦ 1) Information Overload – as size increases, DNA is not able to provide information for all the needs of the cell.
Chapter 10 Cell Growth and Division. Cell Growth Key factors of cell size –Surface area – area around the cell (plasma membrane) –Volume – space inside.
Cell Growth and Division. When cells get too big, two problems happen 1. DNA gets overloaded 2. Materials can’t get exchanged 1. Can’t get into and out.
Intro to topic 3 Notes There are 2 reasons cells divide rather than grow indefinitely. 1. The larger that cells become, the more demand the cell places.
Chapter 10: Cell Growth and Division
Chapter 10 Cell division Review. This spot that holds the 2 chromatid copies together is called a ______________________ centromere The phase of the cell.
Mitosis How do your cells divide? Division of the Cell A. Cell division – the process by which a cell divides into two new daughter cells. B. Before.
