p. 205 A.Q. 1ab, 2ab, 3b, 4b, 5ac 1a. What are the two major
parts of the cell? 1a. The two major parts of the cell are the
cytoplasm (with organelles) and the nucleus. 1b. How is the role of
the nucleus in a cell similar to the role of the captain on a
sports team? 1b. The role of the nucleus is like the captain of a
sports team because the nucleus controls cell activities as a
captain controls plays and players. 2a. What is the function of
lysosomes? 2a. The function of lysosomes is to break down
nutrients, old organelles, and old cells with their enzymes.

p. 205 A.Q. 1ab, 2ab, 3b, 4b, 5ac 2b. How do contractile
vacuoles help maintain water balance? 2b. Contractile vacuoles help
maintain water balance bypumping out excess water.

p. 205 A.Q. 1ab, 2ab, 3b, 4b, 5ac 4b. You examine an unknown
cell under a microscope and discover that the cell contains
chloroplasts. From what type of organism does the cell likely come?

organisms called protists). Plant CellsProtists

p. 205 A.Q. 1ab, 2ab, 3b, 4b, 5ac 5a. Why is the cell membrane
sometimes referred to as a fluid mosaic? What part of the cell
membrane acts like a fluid? And what makes it like a mosaic? 5a.
The cell membrane is sometimes referred to as a fluid mosaic
because it is made of many parts that can float around in the
membrane. 5c. Why do you think its important that cell membranes
are selectively permeable? 5c. Its important that cell membranes
are selectively permeable because selective permeability allows
needed substances to enter the cell and wastes to leave while
keeping out molecules that are not needed.
