Question

cells that move organs and body parts (figure 3.8c)
*skeletal, cardiac, and smooth muscle cells. these cells are elongated and filled with abundant contractile filaments, so they can shorten forcefully and move the bones, pump blood, or change the size of internal (1 ) to move substances around the body. cell that stores nutrients (figure 3.8d)
*fat cell. the huge spherical shape of a fat cell is produced by a large lipid droplet in its cytoplasm. cell that fights disease (figure 3.8e)
*white blood cells such as the macrophage (a phagocytic cell). this cell extends long pseudopods (false feet) to crawl through tissue to reach infection sites. the many (2 ) within the cell digest the infectious microorganisms (such as bacteria) that it \eats.\ cell that gathers information and controls body functions (figure 3.8f)
*nerve cell (neuron). this cell has long processes (extensions) for receiving messages and transmitting them to other structures in the body. the processes are covered with an extensive plasma (3 ), and a plentiful rough er synthesizes membrane components and signaling molecules called neurotransmitters. cells of reproduction (figure 3.8g)
*oocyte (female). the largest cell in the body, this egg cell contains several copies of all (4 ), for distribution to the daughter cells that arise when the fertilized egg divides to become an embryo.
*sperm (male). this cell is long and streamlined, built for swimming to the egg for fertilization. its (5 ) acts as a motile whip to propel the sperm.

Explanation:

1. Muscle - related cells change the size of internal organs to move substances.
2. Lysosomes within white - blood cells digest infectious microorganisms.
3. Nerve cell processes are covered with plasma membrane.
4. Oocytes contain several copies of all organelles for daughter - cell distribution.
5. Sperm's flagellum acts as a whip for propulsion.

Answer:

1. organs
2. lysosomes
3. membrane
4. organelles
5. flagellum
