Reproduction Review
STUDY YOUR GLOSSARY TERMS!!!
1. What is the theory of spontaneous generation? How was it disproved?
Spontaneous generation is the theory that non-living things will be transformed into living things. Francisco
Redi challenged it with his meat experiment, but the advent of the microscope finished it.
2. List the 3 parts of the cell theory.
All living things are composed of one or more cells
The cell is the functional unit of life
All cells come from pre-existing cells
3. Label the nucleus, cell membrane, cytoplasm, cell wall, centrioles, vacuoles and the
chloroplast on the following two cells. (NOTE: some organelles may only be on one of the
cells)
Cell
Membrane
Nucleus
Nucleus
Centrioles
Vacuole
Cell
Membrane
Chloroplast
Cytoplasm
Cell Wall
Cytoplasm
4. Which stage of the cell cycle takes the longest: interphase or cell division?
Interphase.
5. What 3 important things happen to the cell during interphase?
Rapid cell growth
Duplication of chromosomes
More growth
6. How is cytokinesis different between plant and animal cells?
Animal – Cell membrane pinches as they split
Plant – Cell plate forms in the middles of the division to separate dividing cells
