Understanding Cells and Microscopy

What is the primary function of the cell membrane?

• To control what enters and leaves the cell

• To provide energy for the cell

• To store the cell's genetic material

• To conduct photosynthesis

What is the role of the nucleus in a cell?

• It breaks down waste materials

• It is responsible for cellular respiration

• It stores and protects the cell's genetic information

• It assists in the synthesis of proteins

Which of the following is a product of cellular respiration?

• Oxygen

• Glucose

• Carbon dioxide

• Chlorophyll

What is the function of mitochondria in a cell?

• To conduct photosynthesis

• To store genetic information

• To produce energy for the cell

• To synthesize proteins

Which part of the microscope is used to adjust the focus?

• The base

• The eyepiece

• The coarse adjustment knob

• The arm

What is the function of ribosomes in a cell?

• To produce energy

• To synthesize proteins

• To store DNA

• To assist in cell division

Which organelle is known as the "powerhouse of the cell"?

• Chloroplast

• Nucleus

• Mitochondria

• Endoplasmic reticulum

What is the main difference between active and passive transport?

• Active transport requires energy, while passive transport does not

• Passive transport requires energy, while active transport does not

• Active transport can only move materials out of the cell, while passive transport can move materials in and out

• Passive transport can only move materials into the cell, while active transport can move materials in and out

What is the primary role of the Golgi apparatus in a cell?

• To produce energy

• To synthesize proteins

• To modify, sort, and package proteins and lipids for storage or transport out of the cell

• To break down cellular waste

Which part of the microscope allows you to change the magnification?

• The eyepiece

• The objective lenses

• The stage

• The light source
