Cell Discovery and Organization
This man observed cork with his microscope and called the tiny boxes 'cells'
Who was Robert Hooke
This property allows some things to enter/leave the cell, and blocks other things from doing so.
What is selective permeability
This fills the space inside a cell. It is semi-fluid and is composed of water and dissolved materials.
What is cytoplasm?
This organelle provides the cell with the ATP it needs to perform its functions and activities.
What is the mitochondria?
This occurs when particles of a substance move from where there are many particles to where there are few particles.
What is diffusion?
The basic units of all living things
Cells
The part of the phospholipid that 'loves' water
What is the hydrophilic head?
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?
This organelle digests worn out cell parts and also plays a role to defend the cell from infection.
What is a lysosome?
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?
This kind of organism is made of only one cell
Unicellular
The plasma membrane is made up primarily of a bilayer of
Phospholipids
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
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?
This occurs when water diffuses into a cell.
What is osmosis?
This kind of organism is made of many cells
Multicellular
It is the thin barrier that separates the inside of a cell from the outside environment.
Plasma Membrane/Cell Membrane
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?
What is released during cellular respiration?
Energy in the form of ATP
This term refers to the direction the particles are moving; you are either going with it or against it.
What is the concentration gradient?
List each statement of the Cell Theory
1-All living things are made of cells
2-Cells are the basic unit of life
3-Cells only come from other cells
These lipids are located within the phospholipid bilayer, and they function to stabilize the cell membrane
What is cholesterol?
The cell membrane is not a rigid outer layer. The cholesterol allows the membrane to be flexible. What is the term used to describe this model of the membrane
Fluid mosaic model
This organelle controls the passage of materials in and out of the nucleus
Nuclear membrane
This requires ATP to pump against the concentration gradient. This is an example of this type of transport.
What is active transport?
