Scientist who Contributed to Biogenesis and Abiogenesis Scientists who Contributed to the Cell Theory Microscope Animal Cell Plant Cell
100
Aristotle
Who believed in spontaneous generation, and was a member of the church, thus everyone believed him.
100
Hooke
Who discovered "empty room compartments" and referred to these compartments as cells?
100
Resolution
What is the ability of the eye to distinguish between separate objects that are close together?
100
Lysosome
What is a membrane-bound vesicle filled with digestive enzymes that can break down worn-out cell components or material brought into the cell?
100
Central Vacuole
What is the very large membrane-bound fluid-filled storage sac that gives added internal support to a plant cell and contains toxic molecules along with storage molecules?
200
Redi
Whose experiment indicated that maggots were produced only fly eggs were laid and not by spontaneous generation?
200
Leeuwenhoek
Who designed a microscope that enabled him to see tiny particles?
200
Condenser lens
What directs light to the object being viewed?
200
Cell membrane
What is the structure that separates the cell interior from the outside world and controls the movement of material into and out of the cell?
200
Chloroplast
What is a plastid that gives green plants their color and converts the energy in sunlight into stored energy in carbohydrates during photosynthesis?
300
Needham
Whose experiment seemed to indicate that living microscopic organisms were produced spontaneously in brother that have been boiled?
300
Brown
Who discovered the cell nucleus?
300
Medium Power
What magnification is 10X?
300
Nucleus
What is the command center of the cell that contains the DNA blueprints for making proteins?
300
Cell Wall
What is the rigid structure surrounding the cell membrane that protects and supports the cell and allows the material to pass to and from the cell membrane through pores?
400
Spallanzani
Who repeated Needham's experiment but boiled brother for a longer period of time, and had no life appearing in the flask?
400
Schleiden
Who first said "all plants are made of cells"?
400
Coarse adjustment knob
What moves the tube or the stage up or down to bring the object into focus and is used only with the low-power objective lens?
400
Mitrochondrion
What is the powerhouse of the cell where organic molecules are broken down inside a double membrane to release and transfer energy?
400
Cytoskeleton
What extend from the nucleus to the cell membrane and organizes the location of organelles within the cytoplasm?
500
Pasteur
Whose experiment showed that micro-organisms come from other micro-organisms in the air and water; basically disproving abiogenesis.
500
Schwann
Who first said "all animals are made of cells"?
500
Stage
What is the platform that supports the microscope slide?
500
Golgi Apparatus
What is the stack of flattened membrane-bound sacs that receive vesicles from the ER and contain enzymes for modifying proteins and lipids?
500
Eukaryotic
This term describes the both animal and plant cells and it's name stems from "true nucleus"
