In living things, the process of repairing injured cells or growing lost body parts.
What is regeneration?
100
The process by which a cell's nucleus divides to form two identical copies of genetic material.
What is mitosis?
100
These become visible when the cell is about to divide.
What are chromosomes?
100
The expression that is used because cancerous cells divide at a far greater rate than normal, healthy cells. They spread wildly throughout parts of the body.
What is "mitosis gone wild"?
100
These type of organisms are able to grow very large.
What is a multicellular organism?
200
The number of times in a year a deer regenerates its antlers.
What is once a year?
200
Either of two new cells formed by the process of mitosis and cell division.
What are daughter cells?
200
This is leading cause of death in Canada.
What is cancer?
200
An organism having many cells.
What is multicellular?
200
These type of organisms often live in watery, food rich environments because they have to take in all the materials they need through their cell membranes.
What are unicellular organisms?
300
Hydra, lobster legs, lizard tails and starfish are all able to do this.
What is regenerate certain body parts?
300
In a cell nucleus, a threadlike structure that carries genetic material (instructions for producing new cells with the same characteristics as the parent cell).
What are chromosomes?
300
The name given to factors that produce cancer.
What are carcinogens?
300
This type of organism only has one cell.
What is unicellular?
300
Red blood cells, nerve cells, water conducting plant cells are all examples of these types of cells.
What are specialized cells?
400
These types of cells last only a few days or weeks.
What are skin cells?
400
The shortened form of deoxyribonucleic acid.
What is DNA?
400
Daughter cells come from this type of cell during mitosis.
What is a parent cell?
400
New red blood cells are formed in this part of your body.
What is the bone marrow?
400
This type of membrane allows only certain materials to pass though it.
What is selectively permeable?
500
This type of cell is the longest-lived cells in your body and they can last a lifetime.
What are nerve cells?
500
This tiny pond organism was named after a mythical monster. This organism is able to regenerate missing body parts.
What is a hydra?
500
Growing back hair and nails are not examples of this as they grow back from the scalp or cuticle, not from where they were cut off.
What is regeneration?
500
This type of cell has long, branched fibres running from the main part of the cell.
What is a nerve cell?
