Cell-1

What is the difference between Prokaryotic cells and Eukaryotic cells?

• Prokaryotic cells do not have ribosomes when eukaryotic cells do.
• Eukaryotic cells have membrane bound organelles
• Prokaryotes have membrane bound nuclei
• Prokaryotic cells lack nucleus.

What is a peroxisome?

• The power-house of the cell
• An organelle that pulls amino acids together to form proteins
• A small organelle in the cytoplasm that contains the reducing enzyme catalase
• A pocket in the cell for storing DNA

Which cellular junction keeps the skin stretchable?

• Desmosomes
• TIght Junctions
• Gap Junctions
• Intercalated discs

Why are me made up of a vast number of cells?

• This increases the surface area to volume ratio.
• Cells need other cells to survive.
• One cell has difficulty moving around
• This increases the volume to surface area ratio.

Which of the following is true about Rough endoplasmic reticulum?

• It detoxifies the cell.
• It contains the ribosomes which translate proteins
• It stores the proteins produced by the ribosomes
• It synthesizes lipids

Eukaryotes have all of the following organelles except...

• Nucleus
• Nucleolus
• Ribosomes
• Nucleoid

Which of the following is NOT true about Smooth endoplasmic reticulum?

• It synthesizes lipids
• Sends proteins to the Golgi apparatus
• Metabolizes carbohydrates
• Stores calcium

Which of the following is only in animal cells?

• Chloroplast
• Peroxisome
• Lysosome
• Mitochondrion

Which particle can get through a cell membrane?

• Large polar molecule
• Small nonpolar particle
• A water molecule
• Large nonpolar particle

What happens in the nucleolus?

• Lysosomes are commonly found here.
• DNA is mostly concentrated here, rather than anywhere else in the nucleus.
• Ribosomes are produced.
• Proteins are produced.
