Cell theory
This scientist first used the term “cell” after observing cork under a microscope.
Who is Robert Hooke?
This organelle is found in both plant and animal cells and controls the movement of substances in and out of the cell
What is the cell membrane?
This organelle is found in plant but not animal cells and provides protection and structure for the cell.
What is the cell wall?
This double layer makes up the main structure of the cell membrane.
What is the Phospholipid Bilayer?
Diffusion is the movement of molecules from an area of ______ concentration to an area of ______ concentration.
high to low
Cell theory states that, "All cells come from...."
What is other cells?
This organelle transports proteins throughout the cell and acts as a conveyor belt.
What is an endoplasmic reticulum?
Plant cells have a larger one of these because they need more storage of what.
What is a vacuole and water?
This type of protein is loosely attached and may relay chemical signals
What is a peripheral protein?
Water moves across a membrane by a special type of diffusion called what?
What is osmosis?
These two scientists concluded that all plants and animals are made of cells.
Who are Matthias Schleiden and Theodor Schwann?
This a jelly-like substance that fills the cell and helps it hold its shape.
What is cytoplasm?
This cell is circular in shape and does not have a cell wall.
What is an animal cell?
This type of protein extends through one or both sides of the cell membrane.
What is an integral protein?
Diffusion is a type of this kind of transport that does not require energy.
What is passive transport?
This scientist added the idea that all cells come from other cells.
Who is Rudolf Virchow?
This small organelle is often referred to as the factory worker making proteins
What are ribosomes?
The main reactants of photosynthesis are these three things.
What are carbon dioxide, water, and sunlight?
This chain of simple sugars attaches to proteins and lipids to form glycoproteins and glycolipids.
What are carbohydrates?
The main goal of diffusion is to reach this balanced state.
What is equilibrium?
According to Cell Theory, all living things are made of these.
What are cells?
This power making organelle is only in plants and uses sunlight for energy.
What are chloroplast?
The main reactants of cellular respiration are these two substances.
What are glucose and oxygen?
This part of the membrane is found only in animal cells and works to keep the membrane fluid.
What is cholesterol?
If molecules move against the concentration gradient, energy is needed — this is called what?
What is active transport?
