Cell Diversity: Cells are Different!Part 1: Cell Diversity Reading. Directions: Read the following paragraph and answer the questions that follow.

So far, we have learned that cells have many different parts, called organelles. They have a nucleus to control everything, a cell membrane to act as a gatekeeper, and mitochondria to produce energy. We’ve also learned that plant and animal cells have a lot in common, but can be very different! Plant cells have a cell wall for structure, and a large, central vacuole for water storage. They also have chloroplasts that help with photosynthesis. But did you know that not all animal cells look the same? That’s right! In your own body, you have hundreds of different cell types that all have the same basic parts but in different amounts!

1) What are two differences between plant and animal cells? ________________________________________________________________________________________________________________________

2) What are three organelles located in all cells? ________________________________________________________________________________________________________________________

3) What is the main purpose of a vacuole? ________________________________________________________________________________________________________________________

Part 2: Organs and Organelles. Directions: Below is a list of different parts of the human body and the functions they serve. Using the word bank of organelles, describe what organelles you’ll find the MOST of in each cell type. For example, if I know that bone cells need to be very rigid, I would describe them as having more cytoskeleton for more support.

Human Cell Types:

Skeletal Very hard, rigid cells that make up bones

Nervous Long cells that make up nerves and depend on cell signalling

Dermal Soft cells that let nutrients in and out of skin

Gastronal Soft cells that store and digest (break down) food in stomach

Muscular Flexible cells where energy is made and make up muscles.

Organelle Word Bank:

Cell Membrane Lysosome Mitochondria Nucleus Vacuole Golgi Body Mitochondria Cytoskeleton Cytoplasm
