extension - complete the venn diagram to compare active and passive cell transport.
active transport
passive transport

Explanation:

The crossword puzzle and Venn - diagram tasks are related to cell transport concepts in biology. For the crossword:

• Across 4: Protein channels in the cell membrane are made of proteins.
• Across 6: Facilitated diffusion is diffusion through a protein channel.
• Across 8: Active transport requires energy.
• Across 9: Exocytosis uses vesicles to transport materials out of the cell.
• Across 10: Osmosis is the diffusion of water through the cell membrane.
• Across 11: ATP is a type of cell energy used in active transport.
• Across 12: When molecules move from low to high concentration, they move against the concentration gradient.
• Down 1: Phospholipids make up the cell membrane.
• Down 2: Endocytosis uses vesicles to transport materials into the cell.
• Down 3: When molecules move from high to low concentration, they move down the concentration gradient.
• Down 4: Passive transport does not require energy.
• Down 5: The cell membrane is the organelle that regulates what enters and leaves the cell.
• Down 7: Homeostasis is the process of maintaining a balanced internal environment inside a cell.

For the Venn - diagram:

• Active Transport: Requires energy (ATP), moves substances against the concentration gradient.
• Passive Transport: Does not require energy, moves substances down the concentration gradient.
• In the overlap: Both are types of cell transport, involve movement of substances across the cell membrane.
