This organelle controls what enters and leaves the cell.
What is the cell membrane?
This tool is used to view very small objects such as cells.
What is a microscope?
This process moves particles from high to low concentration.
What is diffusion?
This process allows plants to make their own food.
What is photosynthesis?
A group of similar cells working together forms this.
What is a tissue?
This organelle is known as the “powerhouse” of the cell.
What is the mitochondrion?
Increasing the size of an image is called this.
What is magnification?
The movement of water across a semi-permeable membrane is called this.
What is osmosis?
This gas is taken in by plants during photosynthesis.
What is carbon dioxide?
Tissues working together form this level of organization.
What is an organ?
This jelly-like substance holds organelles in place.
What is the cytoplasm?
This type of microscope uses light to view specimens.
What is a light microscope?
This type of transport requires energy from the cell.
What is active transport?
This organelle is where photosynthesis occurs.
What is the chloroplast?
Organs working together form this.
What is an organ system?
This organelle is responsible for protein production.
What are ribosomes?
The total magnification is found by multiplying these two lens powers.
What are the ocular and objective lenses?
A membrane that allows some substances to pass but not others is called this.
What is selectively permeable?
This process releases energy from glucose in cells.
What is cellular respiration?
The smallest level of organization capable of life is this.
What is a cell?
This structure contains DNA and controls cell activities in eukaryotic cells.
What is the nucleus?
This term describes how clear and detailed an image appears.
What is resolution?
This process uses protein channels to help substances cross the membrane without energy.
What is facilitated diffusion?
This molecule is the main energy currency of the cell.
What is ATP?
All the organ systems working together make up this.
What is an organism?
