The Cell Cycle & Cancer
This is the stage of the cell cycle where the cell grows, performs its normal functions, and copies its DNA
What is Interphase?
This is the least complex level in the hierarchy of organization in animals.
What is the cellular level?
This type of blood vessel carries blood away from the heart at a high pressure using thick, muscular walls.
What is an artery?
All respiratory systems, whether simple or complex, depend on this process to move oxygen in and carbon dioxide out.
What is diffusion?
This chemical gives plants their green colour and is the primary chemical used to do photosynthesis.
What is chlorophyll?
These are environmental factors known to cause cancer, such as cigarette smoke, viruses, and X-rays.
What are carcinogens?
Blood, bone, and tendons are all examples of this major type of animal tissue.
What is connective tissue?
This is the muscular action that pushes food down the esophagus to the stomach.
What is peristalsis?
Fish must keep swimming so water continuously moves over these organs, exchanging oxygen for carbon dioxide.
What are gills?
This plant tissue specializes in the transportation of water, minerals, and nutrients throughout the plant.
What is vascular tissue?
During this specific phase of mitosis, chromosomes line up directly along the middle of the cell.
What is Metaphase?
This animal tissue is made of thin sheets of tightly packed cells covering surfaces and lining internal organs.
What is epithelial tissue?
This component of blood is primarily responsible for fighting infections like bacteria and viruses.
What are white blood cells?
This animal lacks a digestive system completely because it is essentially just a reproductive system living inside the digestive tract of others.
What is a tapeworm?
The shoot system is specialized to conduct photosynthesis and to produce these specific structures for sexual reproduction.
What are flowers?
This type of tumour is non-cancerous and only affects surrounding tissue by crowding it.
What is a benign tumour?
This type of animal tissue consists of long, thin cells capable of conducting electrical impulses.
What is nerve tissue?
In the respiratory system, gas exchange between the lungs and the blood takes place in these tiny air sacs.
What are alveoli?
This animal does not have a circulatory system, and instead its digestive system exchanges nutrients directly with a fluid-filled body cavity.
What is a jellyfish?
In photosynthesis, tissues in the leaf use light energy, carbon dioxide, and water to produce oxygen and this specific form of sugar.
What is glucose?
This specific cancer treatment works by destroying rapidly dividing cells throughout the whole body.
What is chemotherapy?
The entire length of the digestive tract is lined with epithelial tissue that secretes this substance to lubricate the tract and protect it from digestive enzymes.
What is mucus?
These three accessory organs help with digestion by supplying digestive enzymes directly to the small intestine.
What are the liver, pancreas, and gall bladder?
Amphibians, like frogs, have lungs but can also exchange gases directly through this organ when it is moist.
What is their skin (or integumentary system)?
These specialized cells in plants are able to open and close to control gas exchange.
What are guard cells?
