“Guided Reading and Study” Student Notes

Chapter 2.4, “Looking Inside Cells”

(A Cross-Referencing Assignment = Skill!)

Directions:

  1. Use the answer key below to cross-reference the notes you took on ‘Looking Inside the Cell’ for this “Guided Reading and Study” lesson.
  2. As you are cross-referencing your notes with the answer-key notes below, ALSO be sure to self-evaluate your original responses by doing the following:
  1. Place a ‘correct’ type of mark on your sheet if you got the response correct (like a star, a check-mark, etc.) 
  2. Replace each incorrect response with the CORRECT response, as seen below. 
  3. Study each question and response by really thinking about the ‘meaning’ of what each statement is ‘messaging’.
  4. Next, in your own mind, paraphrase what you have just studied! Then, practice studying aloud with someone of what you have learned on this sheet! 

Use Target Reading Skills

Possible questions and answers:

  1. How are animal cells different from plant cells?

(Plant cells have a cell wall and chloroplasts.)

  1. What do mitochondria do?

(Mitochondria convert energy in food molecules to energy the cell can use.)

Introduction (pg. 60)

  1. Organelles are tiny cell structures inside a cell that carry out specific functions within the cell.

Enter the Cell (p. 61)

  1. Cell wall
  2. a, b
  3. The cell wall protects and supports the cell.
  4. The cell membrane is just inside the cell wallwith cells that HAVE CELL WALLS.
  5. The cell membrane forms the outside boundary that separates the cell from its environment.
  6. True

Sail On to the Nucleus (p. 62)

  1. a, b, d are all true about the nucleus.

Organelles in the Cytoplasm (pp. 63-66)------

  1. c

Looking Inside Cells (continued)

Mitochondria: Convert energy in food molecules to energy the cell can use to carry out its functions

Endoplasmic reticulum: Carries proteins and other materials from one part of the cell to another

Ribosomes: Produce proteins

Goldi bodies: Receives proteins and other materials from the endoplasmic reticulum, package them, and send them to other parts of the cell or outside the cell

Chloroplasts: found only in plant cells; capture energy from sunlight and use it to make food for the cell

Vacuoles: Are the storage areas of the cell

Lysosomes: Contain chemicals that break down large food particles into smaller ones and break down old cell parts.

Specialized Cells (p. 67)
