What are enzymes and why are they important?

• They store energy in cells

• They help speed up chemical reactions in our bodies

• They provide structural support to cells

• They transport oxygen in the blood

What is a cell?

• A large organism that can live on its own

• The smallest organism that can live on its own

• A type of protein found in the body

• A molecule that stores genetic information

What are the rules of cell theory?

• Cells are made of atoms

• All living things are made up of cells

• Cells can only be found in plants

• Cells are the largest unit of life

Compare and contrast eukaryotes versus prokaryotes.

• Eukaryotes have no nucleus, prokaryotes have a nucleus

• Eukaryotes have DNA packaged within a membrane, prokaryotes do not

• Prokaryotes have mitochondria, eukaryotes do not

• Prokaryotes are larger than eukaryotes

Give an example of prokaryotes and eukaryotes.

• Prokaryotes: plants, Eukaryotes: bacteria

• Prokaryotes: animals, Eukaryotes: fungi

• Prokaryotes: e.coli, Eukaryotes: plants

• Prokaryotes: fungi, Eukaryotes: streptococcus

Compare and contrast plant cells versus animal cells.

• Plant cells have a cell wall, animal cells do not

• Animal cells have chloroplasts, plant cells do not

• Plant cells have mitochondria, animal cells do not

• Animal cells have a cell wall, plant cells do not

What are the main functions of the following organelles: Ribosome, Cell Membrane, Cell Wall, Mitochondria, Chloroplast?

• Ribosome-make proteins, Cell Membrane-controls what enters and exits the cell

  Cell Wall- protects and supports the cell Mitochondria- makes energy

  Chloroplast- photosynthesis

• Ribosome-stores energy, Cell Membrane-provides structural support

  Cell Wall-photosynthesis

  Mitochondria- makes protein

  Chloroplast- protects the cell

• Ribosome-photosynthesis, Cell Membrane-makes proteins

  Cell Wall- makes a barrier around the cell

  Mitochondria- destroys bad bacteria

  Chloroplast- makes protein

• Ribosome-controls cell division, Cell Membrane-stores genetic information

  Cell Wall- photosynthesis

  Mitochondria- photosynthesis

  Chloroplast- stores energy

What is the function of the plasma membrane?

• Stores genetic information

• Protects the cell

• Produces energy

• Transports oxygen
