Most cells in an organism go through a

cycle of growth,development, and division

called the cell cycle

* Chapter 3: From a cell to an organism

Lesson # 1: cell cycle and cell division

Objective: Observe how can one cell become a

multicellular organism

Page 2: Chapter : From a cell to an organism Lesson # 1: cell and life … · 2017. 5. 25. · nuclear membrane breaks down Methaphase: Chromosomes line up in single file Anaphase: sister

* Chapter 3: From a cell to an organism

Lesson # 1: cell cycle and cell division

Objective: Observe how can one cell become a

multicellular organism

PHASES STAGE DESCRIPTION

INTERPHASE

G1 Growth and cellular functions

S Growth and chromosome

replication

G2 Growth and cellular functions

Mitotic phase

mitosis Division of nucleus

cytokinesis Division of cytoplasm, new cells are

formed

* Chapter 3: From a cell to an organism

Lesson # 1: cell cycle and cell division

Objective: Observe how can one cell become a

multicellular organism

Mitosis phases:

Prophase: Nucleolus disappears and nuclear membrane breaks down

Methaphase: Chromosomes line up in single file

Anaphase: sister chromatids separate, spindle fibers begin to shorten

Telophase: nuclear membrane forms around the chromatin, two identical nuclei form

* Chapter 3: From a cell to an organism

Lesson # 1: cell cycle and cell division

Objective: Observe how can one cell become a

multicellular organism

Heredity: passing of traits

from parents to offspring

* Chapter 5: GENETICS

Lesson # 1 and 2: Mendel and His Peas, understanding

inheritance

Objective: Observe how are traits passed from parents to

offspring

Dominant allele: genetic

factor that blocks another

genetic factor

* Chapter 5 : GENETICS

factor that is blocked by the

presence of a dominant

factor
