Cell Theory

Why are microscopes important when studying most cells?

• Most cells are very large.
• Most cells are very small.  
• Most cells move very quickly.
• Most cells are dead.  

This scientist concluded that animals and, in fact, all living things are made of cells:

• Hooke
• Leeunwenhoek
• Schleiden
• Schwann

All existing cells are produced by other

• living cells
• dead cells
• atom cells
• animal cells

This is the most basic unit of life

• atom
• cell
• nucleus
• DNA

The Cell Theory states...

• atoms create all matter
• living things evolve
• the cell is the backbone of all matter
• cells are the basic unit of structure and organization of organisms

"All animals are made of cells". This fact was discovered by...

• Matthias Schleiden
• Theodor Schwann
• Robert Hooke
• Rudolf Virchow

• Hand lens
• Telescope
• Petri dish

This scientist was the first to identify cells and name them:

• Hooke
• Leeunwenhoek
• Schleiden
• Virchow

All cells come from___________ cells.

• pregnant
• pre-existing
• paternal
• pin size

All organisms are made of:

• organelles
• cytoplasm
• DNA
• cells
