Mississippi Science BIO.1C.1
The Standard
- BIO.1C
- Students will relate the diversity of organelles to a variety of specialized cellular functions.
Develop and use models to explore how specialized structures within cells (e.g., nucleus, cytoskeleton, endoplasmic reticulum, ribosomes, Golgi apparatus, lysosomes, mitochondria, chloroplast, centrosomes, and vacuoles) interact to carry out the functions necessary for organism survival.

What This Standard Means
What Students Need to Do
- Build a cell model that shows how organelles work together, not just where they sit. Use it to explain a cell job, such as exporting a protein or breaking down waste.
What Mastery Looks Like
- Students trace instructions from the nucleus to ribosomes, then follow a protein through the rough ER, Golgi, and out of the cell. They explain how a failure at one step changes the result.
Common Misconceptions
- Students may treat organelles as separate parts that never interact. Some think proteins are made in the nucleus or that the Golgi makes proteins rather than sorting and packaging them.
How to Assess It
- Exit ticket: Draw and label how a cell exports a protein, from nucleus instructions to the cell membrane. Mark where export fails if the Golgi stops working, and explain why.

Ways to Teach It
Place organelle cards on a desk and connect the nucleus, ribosomes, rough ER, Golgi, and membrane with yarn to show protein export.
Ask students to write what happens to an exported protein if the rough ER stops working, using two organelles in their explanation.
Give pairs task cards, such as clearing damaged cell parts or making sugar, and have them match organelles and sketch the handoffs.
Place a potted plant by a window and sketch how its chloroplasts make sugar and mitochondria release energy for growth.
