Answer:
The correct answer is both involve moving substance across the membrane.
Explanation:
Passive transport is one of the most important membrane transport process which helps in transport of polar molecules and gases along their concentration gradient across the plasma membrane.No addition energy is required to carry out passive transport because during passive transport molecules move from high concentration region to the region of low concentration.
Active transport is a specific type of membrane transport process which helps in the passage of ions against their concentration gradient across the plasma membrane.As the ions are moving against their concentration gradient additional chemical energy is required to carry out their uphill transport.
Answer:
The endoplasmic reticulum is like a highway or transportation route. it transports everything throughout the cell so it can get where it needs to go. It involves the smooth and rough endoplasmic reticulum.
Explanation:
I hope this helps! It is also in both animal and plant cells.
