Macromolecules
The four major types of macromolecules in living organisms?
What is carbohydrates, proteins, lipids, nucleic acids?
This organelle is known as the control center of the cell.
What is the nucleus?
These are the basic units of structure and function in living things.
What are cells?
These small building blocks join together to form proteins.
What are amino acids?
This energy-producing organelle is often called the powerhouse of the cell.
What is the mitochondrion?
These organisms do not have a nucleus and include bacteria.
What are prokaryotes?
This group of macromolecules includes sugars and starches and is the body’s main energy source.
What are carbohydrates?
This rigid outer layer provides structure and support in plant cells.
What is the cell wall?
This is the jelly-like fluid inside the cell, where chemical reactions take place.
What is cytoplasm?
These three elements are found in all macromolecules.
What are carbon, hydrogen, and oxygen?
This structure inside the nucleus produces ribosomal RNA.
What is the nucleolus?
This process allows cells to maintain a stable internal environment.
What is homeostasis?
Starch, glycogen, and cellulose are all examples of this type of carbohydrate.
What are polysaccharides?
This theory explains how mitochondria and chloroplasts originated from free-living bacteria.
What is the endosymbiotic theory?
This process allows materials to move across the cell membrane without using energy.
What is passive transport?
