Life is Cellular
These are called this term exactly because it reminded him of the tiny rooms that were found in monasteries. They are the basic units of life.
What is a cell?
This organelle contains nearly all the cell's DNA and with it the coded instructions for making proteins and other important molecules.
What is the nucleus?
All cells are surrounded by a thin, flexible barrier known a this.
What is a cell membrane?
Cells throughout an organism can develop in different ways to perform different tasks.
What is cell specialization?
Specialized structures that act like "little organs" in a cell.
What are organelles?
These cells has no defined nucleus and no defined organelles.
What is a prokaryote?
These organelles produce proteins.
What are ribosomes?
The composition of nearly all cell membranes is a doubled layered sheet called this.
What is a lipid biayer?
This process requires energy to get molecules from a lower concentration to a higher concentration, or against the concentration.
What is active transport?
These cells contain a nucleus and membrane bound organelles.
What is a eukaryotic cell?
This scientist discovered cells by using a thin slice of cork and a compound light microscope.
Who is Robert Hooke?
What is the Golgi Apparatus (Golgi Bodies)?
The diffusion of water through a selectively permeable membrane.
What is osmosis?
The movement of specific molecules across cell membranes through protein channels.
What is facilitated diffusion?
This of solution is the mall of a solute in a given volume of solution.
What is concentration?
State the three parts of the cell theory. Must name all three in order to get the full points!
What is...
1) all living things are composed of cells.
2) cells are the basic units of structure and function in living things
3) new cells come from preexisting cells.
Saclike structures that store materials/
What are vacuoles?
Give me all three types of concentrations that can be found in solutions.
What are isotonic, hypertonic, and hypotonic?
Give me all levels of tissue organization in a multicellular organism.
What are cells, tissues, organs, organ systems?
These microtubules help to organize cell division.
What are centrioles?
This scientist observed tiny living organisms in drops of pond water using a microscope.
Who is Anton van Leeuwenhoek?
Eukaryotic cells are given their shape and internal organization by a supporting structure known as this.
What is a cytoskeleton?
The transportation of liquids in vacuoles is known as this.
What is pinocytosis?
The cytoplasm surrounds a particle and packages it. Then, the cell engulfs it.
The site where lipid components, proteins, and other materials are assembles and exported from the cell.
What is the endoplasmic reticulum?
