Amoeba Sisters Cell Cycle and Cancer Video

Put these levels of organization in order, from simplest to most complex: _____.

• cells, tissues, organs, systems, organism
• organs, cells, tissues, systems, organism

• organism, organs, cells, tissues, systems

• tissues, systems, cells, organs, organism

All of these are types of specialized cells in your body EXCEPT

• Neurons

• Muscle Cells

• Sperm cells

• Red blood cells

• Cytocells

How does a multicellular organism grow?

• by lengthening cells

• by differentiating cells

• the cells themselves grow

• by making more cells by division

Why don't we want cell division to happen all the time?

• Because cells would change from a red blood cell to a muscle cell, for example

• It is more likely for cells to become cancerous

• You would grow too large

• You would get infections

In addition to having unregulated cell division, in what other ways are cancer cells different from noncancerous cells?

• The Cells don't communicate and they take nutrients from other cells

• They have different functions

• They make too much energy

• They bring more nutrients to the noncancerous cells

Risk factors for cells becoming cancerous include all these except

• genetic mutations,

• exposure to carcinogens,

• chronic inflammation,

• hormonal imbalances,

• intense exercise

What develops from a group of cancerous cells?

• A tumor
• A branch

• A stem

• A bolus

List 2 types of cancer treatments are _____ and _____.

• Chemotherapy and Radiation therapy

• Electroshock and Radiation Therapy

• Chemotherapy and Electroshock

The 3 cell cycle checkpoints to ensure cells do not exhibit cancerous behavior include all these EXCEPT

• G1 is the cell growing sufficiently

• G2 DNA replicated sufficiently

• S-phase does the cell have enough nutrients

• M-Phase chromosomes lined-up in the middles and spindle fibers attached to each

What is apoptosis?

• signal for cell division

• signal for cell to terminate itself

• signal for cells to make more energy

• signal for cells to not divide
