Question 1

What is the function of the lysosome?

Accepted Answer

breaks down materials

Answer

makes proteins

Answer

makes food

Answer

stores food

Question 2

What is the difference between active and passive transport?

Accepted Answer

active transport uses energy and passive transport does not use energy to transport substances across the membrane

Answer

passive transport moves large molecules across the membrane and active transport moves little molecules.

Answer

active transport water is used to transport substances across the membrane, whereas passive transport does not use water

Answer

active transport moves substances from a high concentration to a low concentration
