What is a Prokaryote?

• A small simple cell containing no nucleus.

• A complex cell containing a nucleus.

What is a Eukaryote?

• A simple cell with no nucleus.

• A complex cell with a nucleus.

What is a nucleus?

• The god of the cell

• Controls activity of the cell - contains genetic material.

• Where aerobic respiration takes place.

• Controls the movement of the cell and chemical reactions.

What is the Cytoplasm?

• Cell sap that gives the cell structure.

• Where photosynthesis occurs.

• Gel-like substance where most chemical reactions happen.

• Where proteins are produced.

What features do animal cells contain? (select all that apply)

• Nucleus

• Ribosomes

• Cytoplasm

• Cell Membrane

• Mitochondria

In addition to features found in animal cells, what elements are only found in plant cells?

• Cell Wall

• Vacuole

• Plasmids

• Chloroplasts

• Mibosomes

What is the job of Ribosomes?

• Where energy is produced.

• Where energy is released.

• Where proteins are made.

• Where enzymes are stored.

What happens in the Mitochondria?

• Aerobic respiration takes place.

• Anaerobic respiration takes place.

• Genetic material is stored.

• Chemical reactions take place.

Which of these are found in bacteria cells?

• Cytoplasm

• Cell Membrane

• Vacuole

• Cell Wall

• Plasmids

What is the equation to figure out magnification?

• Magnification = Strength of lens/ image size

• Magnification = image size/ real size

• Magnification = image size x real size

• Magnification = real size/ image size
