Evolution and Natural Selection
Change over a long period of time.
What is evolution?
He coined the term cells based on a the similarity between a monk's living quarters and what they looked like.
Who is Robert Hooke?
The control center of the cell.
Membrane-bound sacs for storage, digestion, and waste removal; Contains a water solution.
What are vacuoles?
These types of cell don't have a nucleus.
What are prokaryotes?
Created the Theory of Evolution
Who is Charles Darwin?
1st to see live cells under microscope
Who is Antonie van Leeuwenhoek?
This made of a semi-permeable bilayer that surrounds the cell and controls what enters and exits the cell.
What is a cell membrane?
Creates proteins for cells; found floating in cytoplasm or attached to endoplasmic reticulum
What are ribosomes?
The most basic unit of life.
What is a cell?
The organisims that Darwin observed with differences between similar species on different islands.
What are finches and tortoises?
Discovered plants are made up of cells.
Who is Matthias Schleiden?
Thick gel-like liquid inside cell membrane, outside nucleus; other organelles float in it
What is cytoplasm?
The powerhouse of the cell; it combines oxygen and sugar to create energy
What is mitochondria?
The type of cells that have cell walls and cholorplasts.
What are plant cells?
The process by which populations of organisms with variations that help them survive in their environment live longer, compete better, and reproduce more than those that do not have variations.
What is natural selection?
Discovered animals have cells.
Who is Theodor Schwann?
Stack of flattened membranes that look like pancakes. They store, package and release chemicals made in cells.
What is the golgi apparatus/golgi complex/golgi body?
Contains DNA (code for various proteins made by cells) and control center of cell; found inside nucleus, creates ribosomes
What is the Nucleolus?
These types of cells have a nucleus.
What are Eukaryotes?
A peacock's bright feathers are an example of what type of adaptation.
What is a structural adaptation?
Created the cell theory.
Who is Rudolf Virchow?
Contain green chlorophyll where photosynthesis takes place; found in plants.
What are chloroplast?
Made of microtubules; supports cell and provides shape and structure; aids in movement of materials in and out of cells
What is cytoskeleton?
Single-celled organism where the DNA is floating around the cell not in a membrane bound organelle.
What is a prokaryote?
