What are the 3 junctions found in animal cells?

1. Tight Junctions (Knitting)
2. Anchoring Junctions (Rivets)
3. Gap Junctions (Channels)

2

Who is Robert Hooke?

He discovered cells using a microscope in 1665

3

What is a Cytoskeleton?

A network of fibers extending throughout the cell that help support the cell's shape, organize its structure, and control cell movement.
