A Tour of the Cell: Crash Course Biology #23

Who was the first person to use the word "cell" after observing a piece of cork under a microscope?

• Antonie van Leeuwenhoek

• Robert Hooke

• Charles Darwin

• Gregor Mendel

Fill in the blank: Cells that contain a nucleus and membrane-bound organelles are called (a)   cells.

What is the primary function of the cell membrane?

• To produce energy for the cell

• To store genetic information

• To control what enters and leaves the cell

• To build proteins

Fill in the blank: The (a)   is the organelle that contains the cell's DNA and acts as the control center.

Which organelle is responsible for synthesizing (building) proteins?

• Ribosomes

• Vacuoles

• Lysosomes

• Mitochondria

Describe the main role of the Golgi apparatus in the cell.

Which organelle acts like a waste treatment plant by using enzymes to break down materials?

• Nucleus

• Cytoplasm

• Lysosomes

• Endoplasmic Reticulum

Fill in the blank: Mitochondria produce energy for the cell through a process called cellular (a)   .

Which of these structures is found in plant cells but NOT in animal cells?

• Cell membrane

• Cell wall

• Mitochondria

• Nucleus

Why do plant cells have a large central vacuole compared to the smaller ones found in animal cells?
