Cell Theory
This scientist first observed “cells” in a thin slice of cork.
Who is Robert Hooke?
These are the two major types of cells.
What are prokaryotic and eukaryotic?
This structure gives plant cells extra support and protection.
What is the cell wall?
The jelly-like fluid that fills the cell.
What is cytoplasm?
This word describes microbes that are too small to see without a microscope.
What is microscopic?
These two scientists concluded that all plants and animals are made of cells.
Who are Schwann and Schleiden?
This type of cell has no nucleus.
What is prokaryotic?
Plant cells have these green organelles for photosynthesis.
What are chloroplasts?
The “powerhouse” of the cell.
What are mitochondria?
Explain why food can make someone sick even with no visible mold.
Microbes can be present even when they're too small to see.
This scientist stated that all cells come from pre-existing cells.
Who is Rudolf Virchow?
Give one example of a eukaryotic organism.
What are plants, animals, fungi, or protists?
This large structure stores water and supports the plant.
What is the central vacuole?
This organelle stores water, food, and waste.
What is the vacuole?
When microbes multiply, what happens?
They reproduce, increasing in number, making changes more noticeable. When there are enough microbes in a colony, we are able to see them with the naked eye.
Name one thing Anton van Leeuwenhoek is famous for observing.
What are living cells / microorganisms / “animalcules”?
Define unicellular.
What is made of one cell?
True or False: Animal cells have chloroplasts.
What is false?
The rough ER has these attached to it.
What are ribosomes?
Why can microorganisms live and grow before we can see them?
Because they are microscopic and must multiply to become visible.
List the three parts of the Cell Theory.
1. All living things are made of cells
2. Cells are the basic unit of structure and function
3. All cells come from pre-existing cells
This type of organism is unicellular AND prokaryotic.
What is bacteria?
Explain why a plant cell needs both a cell wall and a cell membrane.
The cell wall gives extra structure and support; the cell membrane controls what enters and leaves.
The organelle that breaks down waste and old cell parts.
What is the lysosome?
This phrase reminds us that prokaryotes have no nucleus.
What is "Pro=No"
