Question 5

Consider these two examples of tissues: 1. The body of a slime mold that flows over a rotten log appears to lack any partitioning into distinct cells; however, it does become cellular when it changes form and produces spores.
2)  The surfaces of parasitic flatworms and some insect tissues are "syncytial" layers of living material that developed from a single cell but now contain many nuclei, though they lack partitioning by cell membranes. These tissues actively consume food and produce wastes.
If the cell theory states that "all living things are composed of cells," then

Accepted Answer

A)   neither of these are living tissues because they violate the cell theory.
B)   these examples prove that some vital force is involved, beyond normal cell structures, to give life to living organisms.
C)   these tissues are obviously a bridge between nonliving and primitive living cells.
D)   the general concept of life-is-cellular still holds, since these organisms still utilize cells at some time in their life cycles, though these examples show that cell membranes can be abandoned.
E)   these examples demonstrate that cell membranes are a necessity if a cell is to be classified as "living."F) A) and C)
G) B) and C)

Question 7

Brock's father has inherited a mitochondrial disease. Is Brock in danger of also having this disease?

Accepted Answer

A) True 
 B)False  False

Question 8

Because mitochondria were once independently living prokaryotic cells, if removed from a eukaryotic cell they can survive independently.

Accepted Answer

A) True 
 B)False

Question 9

Explain the purpose of cilia, flagella, and centrosomes in the cell.

Accepted Answer

Answers will vary. Cilia and flagella are hairlike projections that can move either in an undulating fashion, like a whip, or stiffly, like an oar. Flagella function in motility. In single-celled organisms, cilia also function in motility and multicellular organisms' cilia help move substances across the surface of the cell. Centrosomes function as the major microtubule organizing center for the cell.
