Organic Compounds
STRUCTURE & FUNCTION OF ANIMAL/PLANT CELLS
pH SCALE
100
This inorganic compound makes up about 70% of the cell's mass and is essential for chemical reactions.
What is Water (H2O)
100
These are the four main groups of organic compounds found in living things.
What are carbohydrates, lipids, proteins, and nucleic acids?
100
This organelle is known as the “control center” of the cell.
What is the nucleus?
100
A neutral pH value is this number.
What is 7?
200
This gas is used by plants in photosynthesis and released by animals during respiration.
What is carbon dioxide (CO₂)?
200
This type of sugar is the main source of energy for cells.
What is glucose?
200
This jelly-like substance fills the cell and supports organelles.
What is cytoplasm?
200
Substances with a pH below 7 are called this.
300
This inorganic compound helps maintain pH balance and is formed when an acid reacts with a base.
What is a salt?
300
This organic compound stores the genetic blueprint of life.
What is DNA?
300
These organelles are the “powerhouses” of the cell, producing ATP.
What are mitochondria?
400
These substances are needed in small amounts for enzyme function and nerve activity, like calcium and potassium.
What are minerals (ions)?
400
This process joins smaller organic molecules into polymers by removing water.
What is dehydration synthesis?
400
This rigid outer layer gives plant cells shape and support.
What is the cell wall?
500
This process involves the chemical combination of hydrogen and oxygen to form water.
What is synthesis?
500
This molecule is the main structural component of plant cell walls.
What is cellulose?
500
This structure is responsible for making proteins.
What is a ribosome?
