Lesson 1
The cycle of growth, development, and division that a cell goes through.
What is the cell cycle?
True or False: Plants have organs
True
A unicellular organism without a membrane-bound nucleus.
What is a prokaryotic cell?
The period during the cell cycle of a cell's growth and development. A cell spends most of its life in this phase.
What is Interphase?
How many cells does the average human body contain?
37.2 trillion
Consists of Mitosis and Cytokinesis
What is the Mitotic Phase?
The two major categories of unicellular organisms.
What are Prokaryotes and Eukaryotes?
Which stage in the cell cycle is the longest?
The Interphase Stage
Two identical chromosomes that make up a duplicated chromosome.
In what year were cells discovered?
1665
What is the result of mitosis and cytokinesis?
Two daughter cells

What is the result of the cell cycle?
Two new identical cells are created.
The process by which cells become different types of cells.
What is cell differentiation?
How many different types of cells are in the human body?
200
skin, muscle, nerve, intestine, blood, bone, etc.
What is the result of cell division in one-celled organisms?
Reproduction
What are the four main types of tissue found in the human body?
Muscle
Connective
Nervous
Epithelial
How many cells are PRODUCED after two turns in the Cell Cycle?
4
Unspecialized cells that are able to develop into many different cell types.
What are STEM cells?
Approximately how many cells die in the human body each day?
50 to 70 billion
The structure that holds sister chromatids together.
What is a centromere?
What are the three main types of plant tissue?
Dermal
Vascular
Ground

Write your answer. Explain how cell differentiation leads to the organization of a multicellular organism. You must include the following terms in your answer: cell, organ, organ system, stem, tissue
Cell differentiation is the process by which stem cells are specialized. Those cells clump together to form specialized groups like tissues. Tissues group together into specialized organs, and those organs group together into organ systems. All of these specializations come together to form a complete multicellular organism.
What are the phases of Mitosis?
Prophase
Metaphase
Anaphase
Telophase
Approximately, how many new cells are created in the human body each day?
330 billion
