Guide for Reflection Writing Assignment

Step 1: Create an introductory sentence:
o EX: Cells are alive. In order to stay alive cells must move important materials
like water and carbon dioxide, into and out of their cell membrane.

Step 2: Explain how the cell uses diffusion to move sugar, oxygen, and carbon dioxide
into and out of the cell. Use the vocabulary words Diffusion and Osmosis

Step 3: Explain how the cell membrane that surrounds the cell is selectively permeable
and allows certain object into the cell and keeps other objects out. Use the
vocabulary words: Selectively Permeable and cell membrane

Step 4: Explain how when a cell moves object in and out using diffusion it is passive
transport and does not require any energy. Use the vocabulary words: Energy and
Passive transport. It would be nice if you explain that during passive transport
objects are moving from high concentration to low concentration.

Step 5: Explain how a cell must use endocytosis to move large objects like protein
into the cell.

Step 6: Explain how a cell must use exocytosis to move objects out of the cell.

Step 7: Conclusion - Write a brief summary statement. EX: The cell is constantly
