Cell Theory--men and basics

A cell with a nucleus and membrane bound organelles. "Eu" means "true"

• Multicellular

• Eukaryotic cells

• Chromosomes

• Chloroplasts and mitochondria

are 2 organelles have their own DNA, ribosomes and enzymes?

• chloroplasts and mitochondria

• cytoskeleton

• prokaryotic cells

• chromosomes

Cells are small, but come in different shapes and sizes. The reason cells are small is the requirement to get material "in" and "out" of the cell efficiently and adequately. Calculated by dividing the surface (length x width) are by the volume(length x width x height)

• Surface Area to Volume Ratio

• The Number of Microvilli

• Mitochondria

• Cytoskeleton

helps the cell maintain its shape and is also involved in movement. Composed of protein fibers--microtubules are the largest and microfilaments are the smaller ones

• Mitochondria

• Cytoskeleton

• Prokaryotic Cells

• Chromosomes

He developed a simple lens microscope in 1665; basically worked like a magnifying glass
