Prokaryotes, Eukaryotes and Levels of Organization

8C.  A student wants to use the Venn diagram below to show the characteristics of two kingdoms of organisms.  The characteristics that the two kingdoms share will be listed in the shaded area where the circles intersect.  Which of these is a characteristic that the student should list in the shaded part of the diagram?

• Heterotrophic
• Mobile
• Prokaryotic
• Multicellular

8C. The diagram shows taxonomic groups and a major distinguishing characteristic of all but two of them. Which characteristics will be used to complete the chart?

• Motile - Nonmotile
• Nonphotosynthetic - Photosynthetic
• Autotrophic - Heterotrophic
• No nucleus - Nucleus

Some students used information they gathered from lab investigations to prepare a table. They entered the table in their lab notebooks. Which these correctly identifies the two cell described in the table?

• Cell 1 is eukaryotic, and Cell 2 is prokaryotic

• Cell 1 is prokaryotic, and Cell 2 is eukaryotic

• Both Cell 1 and Cell 2 are eukaryotic

• Both Cell 1 and Cell 2 are prokaryotic

The picture shows a student using a microscope to study a prepared slide of a single-celled organism.A single-celled organism can be classified as a prokaryote based on the absence of —

A) a cell membrane B) ribosomes C) chromosomes D) a nucleus

• A

• B

• C

• D

The endosymbiotic theory states that eukaryotic cells evolved from smaller prokaryotes living inside and coevolving with larger prokaryotes.

Which cell part is present in eukaryotic cells, but not in prokaryotic cells?

• cell membrane
• cell wall
• cytoplasm
• nucleus

Which of these is the key idea of the endosymbiont theory?

• Eukaryotes evolved from early prokaryotic cell that developed internal cell membranes.
• Prokaryotic cells evolved from early eukaryotes that were enclosed by cell walls.
• Early prokaryotic cells evolved from chloroplasts.
• Early prokaryotic cells evolved from chemicals that became joined together using the heat given off by deep ocean vents.

Differences between prokaryotes and eukaryotes which are readily observable through the light microscope include:
 
I.  prokaryotes are much smaller than eukaryotes
II.  ribosomes are smaller in prokaryotes
III.  prokaryotes lack nuclei

• I only
• II only
• I and II only
• I and III only

What type of cell is shown?

• Eukaryotic because it has a nucleus
• Eukaryotic because it lacks a nucleus
• Prokaryotic because it has a nucleus
• Prokaryotic because it lacks a nucleus

_____ cells have a membrane bound organelles and a nucleus Ex. ________

• Eukaryotic, bacteria
• Eukaryotic, nuclei
• Eukaryotic, fungi
• Prokaryotic, pseudopods
