Life science review quiz

Prokaryotic means.....

• A microscopic single organism that does not contain a nucleus. An example is bacteria.

• An Organism that does not have a nucleus but has a membrane surrounding the nucleus.

• Pro=Professional and doesn't need a nucleus.

• Nothing.

What best describes a Prokaryote?

• A organism that has no nucleus and is DNA free floats in cytoplasm.

• Bacteria

• Has no nucleus

• None of the above

What is a Eukaryotic?

• Eukaryotes are organisms that have a nucleus and membrane-bound organelles. They can be unicellular or multicellular.

• Eukaryotes have a nucleus and often have cell structures.

• Eukaryotes have nucleus and a membrane surrounding it.

• Eukaryotes are usually found in humans.

What is an endoplasmic reticulum?

HINT: There are 2 correct answers

• The endoplasmic reticulum produces proteins for the rest of the cell to function.

• The ER is a network of membranous tubules within the cytoplasm of a eukaryotic cell, continuous with the nuclear membrane. It usually has ribosomes attached and is involved in protein and lipid synthesis.

  (Got from google dictionary)

• The ER is nothing important.

• The ER is the control center of a cell.

What is a nucleus?

• A nucleus is the "brain" of the cell. The nucleus tells everyone how to function.

• The nucleus is the dictator and tells every organ in the cell what todo and how to do it.

• The nucleus acts the cells respiratory system and as the cell's control center.

• The nucleus helps produce and assemble ribosomes

What is an Vacuole?

• A vacuole is a membrane-bound cell organelle. In animal cells, vacuoles are generally small and help sequester waste products. In plant cells, vacuoles help maintain water balance. Sometimes a single vacuole can take up most of the interior space of the plant cell.

  (Source: Vacuole - National Human Genome Research Institute)

• A vacuole is larger in a animal cell than a plant cell.

• A vacuole is larger in a plant cell than a animal cell.

• A vacuole is a membrane bound organelle that is sometimes single or mostly takes up space.

What is a cell wall?

• You can simply define the cell wall as a semi-rigid thick protective structure that surrounds the cell membrane of some types of cells for protection and defining the shape of the cell.
