Plant vs Animal
This green organelle is found only in plant cells and captures sunlight to make food.
What is a chloroplast?
Often called the "brain" or "boss" of the cell, this organelle holds the DNA and controls all cell activities.
What is the nucleus?
This thin, flexible barrier surrounds all cells and controls what goes in and out.
What is the cell membrane?
This is the smallest, most basic unit of structure and function in all living things.
What is a cell?
This simple type of cell does not have its DNA locked inside a nucleus, like bacteria.
What is a prokaryote (or prokaryotic cell)?
This rigid outer layer is found in plant cells to give them a boxy shape, but is completely missing in animal cells.
What is the cell wall?
This organelle is known as the "powerhouse" because it breaks down food to release energy for the cell.
What is the mitochondrion?
The term used to describe how the cell membrane allows some things to pass through while blocking others.
What is selectively permeable (or semi-permeable)?
According to Cell Theory, all new cells must come from these.
What are pre-existing cells (or older cells)?
This more complex type of cell stores its DNA inside a distinct nucleus, making up plants, animals, and fungi.
What is a eukaryote (or eukaryotic cell)?
Plant cells usually have one massive version of this storage organelle to hold water, while animal cells have several tiny ones.
What is a vacuole?
The clear, jelly-like fluid that fills the cell and holds all the organelles in place.
What is cytoplasm?
The natural spreading out of molecules from an area of high crowding to an area of low crowding without using any energy.
What is diffusion?
A living thing that is made up of only one single cell, like a bacterium.
What is unicellular?
This kingdom of life features cells with a cell wall made of chitin, and they absorb nutrients from dead material rather than doing photosynthesis.
What is Fungi (or mushrooms/yeast)?
This is the general shape of an animal cell because it lacks a rigid outer wall.
What is round (or irregular)?
These tiny, dot-like structures act as little factories that make proteins for the cell.
What are ribosomes?
The special name given strictly to the diffusion of water across a cell membrane.
What is osmosis?
The level of organization that is made up of a group of similar cells working together to do a job, like muscle or skin.
What is a tissue?
The tiny, whip-like tail that some single-celled organisms use to swim around.
What are Flagella?
This is the name of the food-making process that plant cells can do, but animal cells cannot.
What is photosynthesis?
This organelle acts like a post office, packaging up materials and shipping them to other parts of the cell.
What is the Golgi body (or Golgi apparatus)?
The type of transport where a cell has to use its own energy to pump materials across the membrane.
What is active transport?
He is the scientist who looked at cork under an early microscope and coined the word "cell" because it looked like tiny rooms.
Who is Robert Hooke?
This is the primary molecule found inside the nucleus that acts as the blueprint or instruction manual for the cell.
What is DNA?
