Cell Structure and Function Concepts

In this video, Sophie from the Lighthouse Lab introduces a model of an animal cell, explaining its components and structures, known as organelles. She covers the cell membrane, cytoplasm, nucleus, nucleolus, endoplasmic reticulum, Golgi apparatus, and mitochondria, detailing their functions and importance in cell operations. The video aims to enhance understanding of these building blocks of life.

What is the model Sophie is referring to in the video?

• A virus

• A bacterial cell

• An animal cell

• A plant cell

What is the primary function of the cell membrane?

• To produce energy

• To store genetic information

• To regulate the movement of materials in and out of the cell

• To synthesize proteins

What is the gel-like substance that fills the cell called?

• Mitochondria

• Ribosome

• Cytoplasm

• Nucleus

Which organelle is known as the control center of the cell?

• Mitochondria

• Golgi apparatus

• Nucleus

• Endoplasmic reticulum

What is the role of the nucleolus within the nucleus?

• To convert energy

• To produce ribosomes

• To store lipids

• To modify proteins

What is the function of ribosomes in the cell?

• To transport molecules

• To synthesize proteins

• To regulate cell division

• To store energy

What is the primary function of the endoplasmic reticulum?

• To synthesize carbohydrates

• To store genetic material

• To process and transport lipids and proteins

• To produce energy

What does the Golgi apparatus do with molecules?

• It converts them into energy

• It breaks them down

• It stores them

• It modifies, sorts, and packages them

Why are mitochondria referred to as the powerhouse of the cell?

• They store genetic information

• They convert energy from food into a usable form

• They synthesize proteins

• They regulate cell division

What is the main role of mitochondria in the cell?

• To modify proteins

• To produce ribosomes

• To convert energy for cellular functions

• To store lipids
