Build the cell-to-organ hierarchy
See this course’s project requirements
A labeled cell-function model with membrane transport predictions, cell-type comparisons and an explanation connecting cells to tissues and organs.
Keep your working files in your own notebook or software. Save a private description, checklist, and work link in My Proof.
What to include
- Classify supplied living and nonliving observations.
- Label major structures with their distinct functions.
- Compare typical plant, animal and bacterial cells and name an exception.
- Predict two passive-movement directions with permeability assumptions.
- Link cells, tissues and organs and repair the supplied flawed model.
- Include the six changed-case responses with explanations.
Review and revise
Use these criteria to check your work and choose what to improve.
- Method: applies the course-specific rules to the supplied cases with visible intermediate work.
- Accuracy: results agree with the stated facts, units, boundaries and independent checks.
- Reasoning: explains why the result follows and identifies a limitation or unresolved question.
- Transfer: completes changed cases and revises the final project when a relevant assumption changes.

The idea in everyday life
Supplied example: an individual heart muscle cell; a group of coordinated heart muscle cells called cardiac muscle tissue; heart with muscle, connective, nervous and other tissues; heart and blood vessels cooperating in the circulatory system.
In multicellular organisms, similar cooperating cells form tissues; multiple tissues combine in organs; cooperating organs form organ systems. The levels describe organization, not a ranking of importance. A cell structure is not itself an organ of the whole organism.
Build the cell-to-organ hierarchy — worked practice
In multicellular organisms, similar cooperating cells form tissues; multiple tissues combine in organs; cooperating organs form organ systems. The levels describe organization, not a ranking of importance. A cell structure is not itself an organ of the whole organism.
Supplied example: an individual heart muscle cell; a group of coordinated heart muscle cells called cardiac muscle tissue; heart with muscle, connective, nervous and other tissues; heart and blood vessels cooperating in the circulatory system.
1. 1. Order
Arrange the supplied examples from cell to organ system.
You should see: Heart muscle cell → cardiac muscle tissue → heart → circulatory system.
2. 2. Explain
State why the heart is an organ rather than one tissue.
You should see: It contains multiple tissues working together in pumping and support.
3. 3. Locate
Place a mitochondrion relative to the hierarchy.
You should see: An organelle within a cell, below the listed cell level.
4. 4. Transfer
Apply the same relation to plant examples supplied here.
You should see: Leaf cells form tissues; several tissues make a leaf organ; the leaf belongs to the plant organism.
What to finish
A labeled hierarchy with heart and leaf examples and an organelle inset.
Watch for this
Multiple tissue types jointly support heart function. A single cell or a DNA molecule would belong to a different organization level.
How can I tell I understand it?
Classify a changed cooperating structure by its components rather than its size.
