The cell cycle includes what 2 important aspects?
Repair/growth and reproduction
Some organisms reproduce by simple cell division where a single cells duplicates its genetic material. What is this called?
What is the offspring called when only 1 parent supplies all the genetic information?
Clone – single cell and multi-celled organisms can reproduce this way
2 parents genetic information is used to create a unique 3 rd organism. What is this called?
What is the name of specialized sex cells?
Gametes (sperm = male egg=female)
Where are genes found?
In the nucleus of a eukaryotic cell
What is the difference between chromatin and chromatid?
Chromatin – granules of DNA that turn into the strands of chromatid chromatid – strands of DNA or half the“X” of a chromosome
True or false: The number of chromosomes an organism has depends on its size?
False! Example: humans have 46 while silkworms have 54
What holds together the 2 strands of chromatids?
What are the 5 phases of the cell cycle?
I - Interphase P - Prophase M - Metaphase A - Anaphase T - Telophase
What occurs during Interphase?
-95% of a cell’s life is in Interphase -growth, development and repair -looks like an ordinary cell
“Property” – X marks the spot: -1 st phase of mitosis -chromosomes appear and duplicate
“mets” line up -chromosomes move to the center of the cell -spindle fibers form and attach to centromeres
“Ana banana split” -chromosomes are pulled apart and move to the poles of the cell
“telephone” – 2 people talking: -2 new daughter cells are formed -cell heads back into Interphase -cells are more efficient at this size to perform all functions
What is the division of the cytoplasm called?
What is the sequence of the cell cycle using letters?
What is a carcinogen?
Something that causes cancer by mutating rapidly dividing and multiplying cells
The cell cycle and mitosis. Cells constantly reproduce exact duplicates of themselves. Why? Replacement Repair Growth.
I.Sexual Reproduction --two parents combine. 1. The sex cell from the male parent is sperm. a. Sperm head is almost all nucleus (genetic info) 2. The.
SC.912.L Compare and contrast mitosis and meiosis and relate to the processes of sexual and asexual reproduction and their consequences for genetic.
Cell Cycle IPMATC. Cell Cycle 3 Parts: – Interphase – Mitosis Prophase Metaphase Anaphase Telophase – Cytokinesis.
Meiosis Pgs Human body cells have 46 chromosomes Meiosis - General Overview Sexual Reproduction and Genetics Each parent contributes 23 chromosomes.
Cell Growth and Division Mitosis and Meiosis. Cell Growth When an organism grows, the number of cells increase but the size of each cell remains small.
Mitosis and Cytokinesis B-2.6 Summarize the characteristics of the cell cycle: interphase (called G1, S, G2); the phases of mitosis (called prophase, metaphase,
Biology AHSGE Standard VI- Mitosis and Meiosis. Biology AHSGE CONTENT STANDARD 6. Describe the roles of mitotic and meiotic divisions during reproduction,
SEXUAL REPRODUCTION Sex cells formed by meiosis Requires 2 parents Offspring not identical The process that results in the formation of gametes Sex cells,
Cell Cycle & Mitosis. 2 Cell Division All cells are derived from pre- existing cells All cells are derived from pre- existing cells New cells are produced.

Cell Division Mitosis Chapter 10. Why do cells divide, rather than continually grow forever? The larger a cell becomes, the more demands the cell places.
AQA Biology AS Level Unit 2 Meiosis, Mitosis and the Cell Cycle.
MEIOSIS AND SEXUAL LIFE CHANGES. YOU MUST KNOW… THE DIFFERENCES BETWEEN ASEXUAL AND SEXUAL REPRODUCTION THE ROLE OF MEIOSIS AND FERTILIZATION IN SEXUALLY.
Phases of Cell Division Interphase (stage between cell division) Interphase (stage between cell division) Prophase Prophase Metaphase Metaphase Anaphase.
Meiosis – the basis of sexual reproduction Section 6.1.
Mitosis & Cytokinesis Cell Growth and Reproduction Ch. 8.2.
The Cell Cycle. Chromosomes Carry genetic information in eukaryotes Carry genetic information in eukaryotes Made of DNA and proteins Made of DNA and proteins.
9.1 All cells come from cells. I. Repair and Growth A.The outermost layer of your skin is actually a layer of dead cells B.Underneath the outer layer.
The Cell Cycle Mitosis. The Cell Cycle The regular sequence of growth and division that cells undergo.
Cell Division The Cell Cycle: Interphase Mitosis Cytokinesis.
Cell Cycle: M Phase Mitosis and Cytokinesis. Cell Division (M phase) Occurs in two stages – Mitosis (nuclear division) – Cytokinesis (cytoplasmic division)
N-6 Cell Division What do cells spend their time doing? Why do they do this?
Mitosis and the Cell Cycle Cell reproduction. Todays Objectives The student will be able to identify the phases of the cell cycle and mitotic stages by.

Genetics--Nuclear Division & Inheritance Mitosis & Meiosis.
Meiosis. Meiosis is the type of division which: 1. Reduces the chromosome # from diploid to haploid 2. Is used to produce gametes: eggs and sperm.
