Cells
This structure controls what enters and leaves the cell.
What is the cell membrane?
This type of cell division produces two genetically identical daughter cells.
What is mitosis?
Plants use this energy source to begin photosynthesis.
What is sunlight?
This body system transports oxygen, nutrients, and wastes throughout the body.
What is the circulatory system?
The basic unit of life.
What is a cell?
This organelle is known as the "control center" of the cell because it contains DNA.
What is the nucleus?
This type of cell division produces four genetically different gametes.
What is meiosis?
This gas is taken in by plants during photosynthesis.
What is carbon dioxide?
This body system includes the brain and spinal cord.
What is the nervous system?
The passing of traits from parents to offspring is called this.
What is heredity?
These organelles produce ATP and are often called the "powerhouses" of the cell.
What are mitochondria?
Double Jeopardy!
During this phase of mitosis, chromosomes line up in the middle of the cell.
What is metaphase?
This sugar is produced during photosynthesis.
What is glucose?
This body system is responsible for exchanging oxygen and carbon dioxide.
What is the respiratory system?
This molecule carries genetic information in living things.
What is DNA?
Plant cells have this organelle that captures sunlight for photosynthesis.
What is the chloroplast?
This process during meiosis increases genetic variation by exchanging DNA between homologous chromosomes.
What is crossing over?
Cellular respiration primarily occurs in this organelle.
What is the mitochondrion (mitochondria)?
This body system breaks down food and absorbs nutrients.
What is the digestive system?
This level of organization is made of similar cells working together.
What is a tissue?
This jelly-like substance fills the cell and surrounds the organelles.
What is cytoplasm?
Human body cells contain this number of chromosomes, while gametes contain half that amount.
What is 46 chromosomes?
This molecule is the main energy currency produced during cellular respiration.
What is ATP?
This body system produces hormones that regulate body functions.
What is the endocrine system?
Double Jeopardy!
This term describes the total number of chromosomes in a body cell.
What is diploid?
