This structure surrounds the cell membrane in a plant cell.
What is a cell wall?
100
It contains the cell's DNA and is the control center of the cell.
What is the nucelus?

Two or more different popluations living in the same area make up one of these.
What is a community?
200
They are also called bacteria. They are the world's smallest cells, and they do not have a true nucleus.
What are prokaryotic cells?
200
These flattened, membrane-covered sacs contain chlorophyll which turns them green. They are essential for photosynthesis to occur.
What are chloroplasts?
200
Amino acids are hooked together here to form proteins.
What are ribosomes?
200
They are the "power houses" of the cell. They are where sugar gets converted into ATP/usable energy.
What are mitochondria?
200
A group of cells that work together to perform a specific job in the body.
What is a tissue?
300
This theory states that: 1. All organisms are compsed of one or more cells. 2. The cell is the basic unit of life. 3. All cells come from existing cells.
What is cell theory?
300
In this process, the energy from sunlight is trapped to make sugar.
What is photosynthesis
300
The "factory floor" where proteins are made. Its appearance is due to ribosomes within it.
What is the rough endoplasmic reticulum?
300
These structures are like the toilet of the cell. They digest food particles, wastes, cell parts, and foreign invaders.
What are lysosomes?
300
When two or more tissues work together to perform a specific job in the body they form this.
What is an organ?
400
These are the structures that enable cells to live, grow, and reproduce.
What are organelles?
400
These are usually the largest organelles in a plant cell.
What are vacuoles?
400
This structure packages, processes, and transports materials out of the cell.
What is the golgi complex?
400
The fluid that surrounds the chemicals and structures of the cell.
What is the cytoplasm?
400
This is the body's largest organ. An average sized person's skin has a mass of about 9 lbs.

He looked at pond scum through his microscope and coined the term "animalcules" to describe the creatures he saw swimming around.
Who is Anton van Leeuwenhoek (LAY VUN HOOK)?
500
You find both these structures in plants for making energy.
What are chloroplasts and mitochondria.
500
They store food, water, and other minerals in a cell.
What are vacuoles?
500
Lipids are made here giving it its "smooth" appearance.
What is the smooth endoplasmic reticulum?
500
A change in an organisms environment that affects teh activity of the organism is called this.
