Levels of Organization
History of the Cell
100

I am the control center of the cell. 

Nucleus
100
The diffusion of water through a selectively permeable membrane. 

Osmosis

100

In eukaryotic cells, all cellular contents outside the nucleus. 

Cytoplasm

100

A group of organs that work together to perform a specific function

Organ system

100

A thin flexible barrier that surrounds cells. 

Cell membrane

200

I am the powerhouse of the cell. 

Mitochondria

200

This happens to a healthy cell dropped into a hypotonic solution. 

Swells

200

When the concentration of two solutions is the same. 

Isotonic

200

A group of tissues that work together.

Organ

200

Cells that enclose their DNA in nuclei.

Eukaryote

300

I am used for storage in the cell. 

Vacuole

300
This happens to the water in a healthy cell that is dropped into a hypertonic solution.

It moves out of the cell.

300

Property of biological membranes that allows some substances to pass across it while others cannot

Selectively permeable
300

A group of similar cells that performs a particular function.

Tissue
300

Cells that do not enclose DNA in nuclei

Prokaryote

400

We are the two cellular boundaries. 

Cell membrane & cell wall

400

We are the two modes of passive transport. 

Diffusion and Facilitated Diffusion

400

Network of protein filaments in a eukaryotic cell that gives the cell its shape and internal organization and is involved in movement.

Cytoskeleton

400

On or in a cell, a specific protein to whose shape fits that of a specific molecular messenger, such as a hormone

Receptor

400
Microscopes use lenses to magnify the image of an object by focusing one of these two things. 

Light or Electrons

500

These 3 organelles help make and transport proteins.

Ribosomes, Endoplasmic Reticulum, and Golgi Apparatus.

500
We are the 3 modes of active transport. 

Exocytosis, Endocytosis and Protein pumps.

500

Specialized structure that performs important cellular functions within a cell.

Organelle
500

Relatively constant internal physical and chemical conditions that organisms maintain. 

Homeostasis

500
Englishman that looked at a slice of cork under the microscope and said they looked like thousands to tiny empty chambers and called them cells.
