How do trees maintain homeostasis in winter?

Back

Trees lose leaves to reduce water loss and conserve energy during winter.

What are endocytosis and exocytosis?

Back

Endocytosis is the process of taking substances into a cell, while exocytosis is the process of expelling substances from a cell.

What is the difference between active and passive transport?

Back

Active transport requires energy to move substances against their concentration gradient, while passive transport does not require energy.
