Mitosis
The phase where chromosomes line up in the middle.
Metaphase
A possible explanation of observations.
Hypothesis
All living things are made of one or more cells.
Cells are the basic unit of structure and function in all organisms.
All cells come from previously existing cells.
The three tenets of cell theory
This organelle is the powerhouse of the cell.
Mitochondria
Orca whales favorite food
Seals
Chromosomes become visible as the cell prepares to continue with mitosis
Prophase
Factors in an experiment that must be controlled
Variables
The father of modern cell theory. He was the first to publish and his colleagues later expanded on his work.
Rudolph Virchow
The protective coating of the cell. Acts as a gatekeeper and determines what can enter or leave the cell.
Cell membrane
Mr. Drew's favorite hockey team
Toronto Maple Leafs
The final phase of mitosis where two daughter cells are formed.
Telophase
A hypothesis must be a __________ statement
Testable
Scientist who coined the name "cells" when looking at tree bark under a microscope.
Robert Hooke
Provides structure to plant cells. Not found in animal cells.
Cell wall
This type of eagle is capable of lifting a fully grown mountain goat up into the air.
Golden eagle
A set of chromosomes moves from the middle to each end of the cell.
Anaphase
The first step of the scientific process. These are the beginning of every scientific discovery.
Observations
This scientist disproved the theory of spontaneous generation through the use of clever experimental design.
Francesco Redi
A gel like substance that fills the cell giving it shape and enabling things to move around the cell.
Cytoplasm
What animal hunts by hypnotizing its prey?
Cuttlefish
The number of chromosomes in a human cell during metaphase.
92 (2 sets of 46)
Formed after the hypothesis has been tested many times and is supported by much evidence.
Theory
The theory that cell theory replaced. It was developed by Aristotle when he observed flies and maggots on rotting meat.
Theory of spontaneous generation
The "brain" of the cell. Disappears during mitosis.
Nucleus
This test can be done from 12am-3am to see if an animal has intestinal round worms.
