Main Idea Details
Skim Section 3 of the chapter. Write two questions that come to mind from reading the headings and the illustration captions.
1. Accept all reasonable responses.
2.
Use your book or dictionary to define enzyme.
protein that speeds up the rate of a chemical reaction
Write each term in the table under the heading that best describes it.
Compare and contrast each pair of terms by defining them and noting their differences.

Compare the cytoplasm and cytoskeleton by defining each in the boxes.
Cytoplasm Cytoskeletonsemifluid material inside the organelles or plasma membrane in which cell processes take place directly
supporting network of long, thin protein fibers forming a framework for the cell and providing an anchor for organelles
Identify the part of the cell that corresponds to each function described.
nucleus directs cell processes; contains the cell’s DNA; stores information for cell growth, function, and reproduction
nuclear envelope double membrane that surrounds the nucleus
ribosome helps manufacture proteins
nucleolus produces ribosomes inside the nucleus
endoplasmic reticulum site of ribosome attachment; can be smooth or rough
Golgi apparatus modifies, sorts, and packages proteins for transport outside the cell
vacuole membrane-bound storage area within the cell
lysosome vesicle that contains substances that digest excess or worn-out organelles
centriole structure near the nucleus that functions during cell division
mitochondrion converts fuel particles (sugars) into useable energy
chloroplast captures light energy and converts it to chemical energy through photosynthesis
cell wall gives support to plant cells
cilia and flagella projections that allow the cell to move or to move substances along the surface of the cell

cytoskeleton, endoplasmic reticulum, Golgi apparatus, mitochondrion, nucleus, plasma membrane, ribosome, vacuole, flagella
centriole, cilia, lysosome
Create and describe a unique model for the structure and function of the cell.
Accept all reasonable responses. Responses should mention specific cell parts and their role
in the metaphor.
CONNECT
Model a eukaryotic cell. Label the nucleus and five organelles.
Accept all reasonable models. Students should include and label the plasma membrane, nucleus, and other organelles, such as mitochondria or chloroplasts.
