This man observed cork with his microscope and called the tiny boxes 'cells'
Who was Robert Hooke
100
This property allows some things to enter/leave the cell, and blocks other things from doing so.
What is selective permeability?
100
This fills the space inside a cell. It is semi-fluid and is composed of water and dissolved materials.
What is cytoplasm?
100
This organelle provides the cell with the ATP it needs to perform its functions and activities.
What is the mitochondria?
100
This occurs when particles of a substance move from where there are many particles to where there are few particles.
What is diffusion?
200
This cell type contains a nucleus and organelles (such as mitochondria).
What are eukaryotic cells?
200
The part of the phospholipid that 'loves' water
What is the hydrophilic head?
200
This organelle directs cell processes by providing DNA instructions. It is surrounded by its own membrane and is covered with pores.
What is the nucleus?
200
These structures are used for cell movement. The first is long and there are usually very few of them. The second are short and there are usually many of them.
What flagella and cilia?
200
The type of diffusion that occurs when a transport protein is required to move large molecules along with the concentration gradient.
What is facilitated diffusion?
300
Simple, compound, light, electron and transmission are all terms that relate to:
What are microscopes?
300
Large molecules that cannot pass through the phospholipid bilayer must pass through these.
What are transport proteins?cell
300
This organelle is a series of flattened membranes. Cell products pass through these membranes and become packaged for delivery in or out of the cell.
What is the Golgi apparatus
300
This organelle digests worn out cell parts and also plays a role to defend the cell from infection.
What is a lysosome?
300
This occurs when water diffuses into a cell.
What is osmosis?
400
This cell type has no nucleus or other organelles. Bacteria are the only example of this cell type.
What is a prokaryotic cell?
400
Large molecules that cannot pass through the phospholipid bilayer must pass through these.
What are transport proteins?
400
This organelle is a series of interconnected passageways. Proteins and lipids are synthesized (put together) here also. There are two varieties 'S' and 'R'.
What is the endoplasmic reticulum?
400
These are made by the nucleolus and their function is to follow DNA instructions to make stuff. They are free-floating or may be found attached to the ER.
What are ribosomes?
400
This term refers to the direction the particles are moving; you are either going with it or against it.
What is the concentration gradient?
500
list each statement of the cell theory... list the 3 statements
1. All living things are made of cells. 2. Cells are the basic unit of life. 3. Cells only come from other cells.
500
These lipids are located within the phospholipid bilayer, and they function to stablize the cell membrane
What is cholesterol?
500
This organelle is found only in animal cells. It is made of microtubules and is thought to play a role in cell division.
What are centrioles?
500
The three differences between plant and animal cells are:
1. Plant cells have cell walls. 2. Plant cells have chloroplasts 3. Animal cells have centrioles.
500
The sodium/potassium pump requires ATP to pump against the concentration gradient. This is an example of this type of transport.
