Cell Structures
Smallest organelle in the cell, responsible for making protein; found in both prokaryotes and eukaryotes
what is a ribosome?
Original cells; first appeared in the fossil record 3.5 billion years ago
What is a prokaryote?
First scientist to use the term "cell" when referring to the small compartments seen in a thin slice of cork under a microscope
Who is Robert Hooke?
Both chloroplasts and mitochondria are able to produce their own enzymes for their metabolism because both possess this organelle
What is a ribosome?
The portion of the phospholipid molecule that is hydrophobic
What is the fatty acid chain?
Storage organelle, largest organelle in plant cells
What is a vacuole?
The most common modern organism to be considered a prokaryote
What is bacteria?
Scientist who was a botanist and made the observation that all plants are made of cells
Who is Matthias Schleiden?
Both chloroplasts and mitochondria are able to reproduce themselves within a cell because they possess this important molecule
What is their own DNA?
The portion of the phospholipid molecule that is hydrophilic
What is the phosphate head?
What is a lysosome?
Cell type for the following kingdoms - Fungi, Protists, Plants and Animals
What are eukaryotes?
German physician who observed that cells come only from pre-existing cells
Who is Rudolph Virchow?
Mitochondria and Chloroplasts are both approximately the same size as this modern day organism
What are bacteria?
A term used to describe a molecule that will repel water
What is hydrophobic?
Organelle made of proteins like tubulin and actin that provides structure to the cell
What is the cytoskeleton?
Cell type that contains a nucleus
What is a eukaryote?
Scientist who theorized that mitochondria and chloroplasts were once free-living prokaryotes before being "eaten" by other prokaryotes
Who is Lynn Marguilis?
This characteristic of both mitochondria and chloroplasts suggests that they were originally consumed by a larger prokaryotic cell but not digested
What is a double membrane?
The main focus or purpose of the cell membrane
What is being selectively or semi permeable?
Made mostly of proteins and water, provides a medium for cell metabolism
Contains organelles that are surrounded by a membrane - vacuoles, mitochondria and chloroplasts, for examples
Scientist who was the first to observe living cells in a drop of pond water
Who is Anton van Leeuwenhoek?
This process occurs in modern day chloroplasts and is suggested as providing an advantage to the early prokaryote that originally consumed the early chloroplast
What is photosynthesis?
Which of the four molecules of life were not depicted in the diagram of the cell membrane on our notes...because they aren't part of the cell membrane
What are the Nucleic Acids?
