Cell Structure and Function Study Guide

Cells and Transport Teaching Resources · High school biology; AP extensions where noted.

Use this guide after an introduction to cell structures and before a cell model or unit assessment. The tasks below ask students to explain relationships, not just recall names. Materials: notebook, pencil, and a teacher-selected cell diagram. Students should already know the meanings of cell, organelle, and membrane.

Learning objectives

  • Compare prokaryotic and eukaryotic organization.
  • Use structure and function to explain a cell’s work.
  • Connect a diagram to a written explanation and identify limits of a model.

How to study

  1. Try the prompts without notes.
  2. Check gaps with the cell parts reference.
  3. Revise in a different color and explain why your answer changed.
  4. Return to the unanswered prompts later rather than immediately rereading everything.

Part 1: compare cells

  1. List four features shared by a typical bacterial cell and a typical animal cell.
  2. A drawing shows DNA but no membrane-bound nucleus. What organization does this suggest, and what additional evidence would you want?
  3. Explain why a root cell can be a plant cell even when it lacks chloroplasts.
  4. Distinguish a plasma membrane from a cell wall using location and function.

Part 2: explain the work

  1. Trace a protein made for secretion through at least four structures. Add an arrow and a short explanation for each transfer.
  2. Predict how reduced ribosome function could affect a growing cell. Separate your observation from your explanation.
  3. Explain why a photosynthetic leaf cell may need both chloroplasts and mitochondria.
  4. Choose a specialized cell and connect two structural features to its function. Use evidence from an approved diagram or reading.

Part 3: build a diagram

Draw a simplified plant or animal cell. Label a membrane, nucleus, ribosomes, ER, Golgi apparatus, and mitochondria. Add plant structures when appropriate. Use arrows to show one process; include a caption stating that the drawing is simplified and not to scale. Do not label an organelle merely because every example in a textbook includes it.

Feedback on selected original prompts

Shared features: DNA, ribosomes, cytoplasm, and a plasma membrane belong in the first answer. A nucleus does not. Secretion pathway: a suitable explanation connects ER-associated ribosomes, ER, Golgi, transport vesicles, and the plasma membrane. Not all proteins follow this route. Leaf cell: photosynthesis captures light energy into chemical forms; mitochondria help convert energy from fuels into ATP usable for cell work. “Plants do not respire” is an error.

Legacy download

Download the existing Cell Structure and Function Study Guide (Word .doc). It contains prompts on cell theory, cell parts, comparisons, and additional topics including apoptosis. Its footer credits a Brookings school resource. Teachers should select relevant questions and check local reuse permissions before adapting or distributing it. The explanations above address the new on-page prompts, not an answer key to that document.

Teaching note: Use student explanations to choose reteaching. A student who can label mitochondria but cannot explain their role needs a different next task from a student who confuses cell walls with membranes. For AP, add a compartmentalization explanation supported by a diagram.
