Question

1. passive and active transport (2.6, 2.9) make a chart comparing passive and active transport. include direction of concentration gradient, examples of molecules, use of energy, and types of cell structures/molecules needed for the process.

create a chart that distinguishes between endocytosis and exocytosis (2.6, 2.9)

Explanation:

To compare passive and active transport, list key - aspects like concentration gradient direction (passive is high to low, active can be low to high), energy use (passive no, active yes), examples of molecules (e.g., oxygen for passive, sodium - potassium ions for active), and cell structures/molecules needed (passive may use channels, active uses pumps). For endocytosis and exocytosis, consider that endocytosis takes substances into the cell and exocytosis releases substances out of the cell, and list relevant cell membrane changes and vesicle involvement.

Answer:

Comparison Aspect	Passive Transport	Active Transport
Use of Energy	No	Yes
Examples of Molecules	Oxygen, carbon dioxide	Sodium - potassium ions
Cell Structures/Molecules Needed	Channels, carriers	Pumps

Comparison Aspect	Endocytosis	Exocytosis
Cell Membrane Changes	Forms vesicles to engulf substances	Vesicles fuse with cell membrane to release substances
Vesicle Involvement	Vesicles are formed from cell membrane	Vesicles are released from the cell
