What are the three principles of cell theory?
What is 1. Cells are the basic unit of life 2. All living things are made of cells 3. All cells are produced from existing cells
500
Unlike the cell membrane, the cell wall is
What is a rigid structure

How are endocytosis and exocytosis similar? How are they different?
Both are forms of active transport of large molecules carried out by movements of the cell membrane. Endocytosis involves taking material into the cell, whereas exocytosis involves moving material out of the cell.

Distinguish between microfilaments and microtubules
What is microtubules are hollow tubes of protein that help maintain the shape of the cell. Microtubules also make up cilia and flagella, which function in cell movement. Microfilaments are long, thin fibers that are narrower than microtubules. Microfilaments function in the movement and support the cell
