Grade 8 Science - Cell Analogy

Your task is to demonstrate your vast knowledge of cell organelle function, structure and size.

A Cellular Story

Time to put on that creative writing hat! You need to show off your understanding of cell structure through story, a comic, a map, or any other ways you think would be best! Use the story as a vehicle to explain the physical structure of each organelle, how big they are compared to the other organelles and their function within a plant or animal cell.

A few “off the top of my head” ideas:

➢ Your main character is adventuring inside a cell.

➢ Your main character is a doctor, trying to diagnose a patient with a cellular problem.

➢ Your main characters are organelles, having some sort of “self-help group” meeting.

Organelles:

← Cell wall (plant cell only)

← Chloroplasts (plant cell only)

← Cell membrane

← Nucleus

← Cytoplasm

← Golgi apparatus

← Ribosome

← Endoplasmic Reticulum

← Vacuole

← Mitochondria

← Lysosome
