Science Module B Unit 2: Lessons 1, 2,3,5 Review

What type of organism can be found in extreme environments such as hot springs?

• DNA

• Viruses

• Archaea

• Eukaryotes

How does a virus use a host to reproduce?

• The virus only uses a host cell for shelter; it does not use a host cell to reproduce.

• The host cell only provides the virus with the food it needs to reproduce on its own.

• The virus can replicate its own genetic material, but it uses the host for the process of conjugation.

• The host cell provides the virus with resources and shelter; its proteins replicate the genetic material of the virus.

Bacteria are generally found in which three shapes?

• Sphere, rod, spiral

• Polygon, cylinder, sphere

• Tube, spiral, hexagon

• Disc, sphere, spacecraft

How does the process of binary fission work in the asexual reproduction of bacteria?

• Two cells join to become one larger cell.

• One cell splits into two cells with identical DNA

• DNA material from the environment is added to the cell.

• Bacteria can only reproduce via sexual reproduction, not asexual reproduction.

What are mycorrhizae?

• Mycorrhizae are one of the three main types of fungi.

• Mycorrhizae are the threadlike strands of a fungus used in reproduction.

• Mycorrhizae are formed by a partnership between fungi and the roots of plants.

• Mycorrhizae are formed by a partnership between fungi and green algae or cyanobacterium.

What are three different groups of protists?

• plantlike, animal-like, fungus-like

• unicellular, multi-cellular, prokaryotic

• with nucleus, without nucleus, gamete

• budding, binary fission, fragmentation

In which of the following situations would an organism produce spores?

• adding water to baking soda

• a tree sending roots underground

• algae becoming abundant in a backyard pond

• bread left out on a counter and allowed to mold

How do the cilia and flagella of protists differ from those of bacteria?

• Bacteria do not have cilia or flagella while protists have both.

• Bacteria only have cilia while protists have both cilia and flagella.

• Bacteria have complex cilia and flagella while protists have simple cilia and flagella.

• Bacteria have simple cilia and flagella while protists have complex cilia and flagella.

What is the function of stems in vascular plants?

• They make food for the plants.

• They absorb minerals from the soil.

• They hold plants in place in the soil.

• They support the plants and keep them upright.

What is the name of the process that allows plants to produce their own food?

• glucose

• chlorophyll

• chloroplasts

• photosynthesis
