Cell Structure and Transport Review

How does the cell membrane help maintain homeostasis in each cell?

• The cell membrane allows all substances to pass through freely

• The cell membrane controls the movement of substances in and out of the cell

• The cell membrane provides energy for the cell

• The cell membrane produces proteins necessary for cell function

What is the correct description of the transport in the image?

• small molecules crossing the lipid bilayer (diffusion)

• large molecules crossing through a protein (facilitated diffusion)

• many molecules coming into the cell using a membrane vesicle (endocytosis)

• many molecules coming out of the cell using a vesicle to fuse with the membrane (exocytosis)

Using the image, choose the correct form of transport and explanation of how you know:

• Active transport, because the molecules are crossing the membrane using a protein

• Passive transport because the molecules are crossing the membrane using a protein

• Active transport because the molecules are moving from low to high concentration

• Passive transport because the molecules are moving from high to low concentration

• F

• G

• H

• J

Imagine you're a tiny detective, investigating a mysterious organism. What clue would tell you that this organism is a prokaryote?

• Its ability to groove and move

• Its ability to respond to your detective questions

• Its unique shape and size

• Its lack of membrane-bound organelles, like a secret hideout

Let's dive into the microscopic world! Can you tell me which structure is exclusive to our complex eukaryotic cells?

• DNA

• Phospholipid membrane

• Nuclear membrane

• Cytoplasm

Imagine you're a tiny molecule, trying to get through a cell membrane. Which method would you choose if you're feeling lazy and don't want to use any energy?

• Active 

• Vacuole 

• Passive 

• Na/K Pump 

Imagine you're a tiny explorer, journeying through the vast landscape of a cell. You stumble upon an organelle that's buzzing with energy. What is it called?

• Mitochondria 

• Golgi Body 

• Vesicle 

• Vacuole

Let's dive into the world of biology! Can you tell me what 'facilitated diffusion' is all about?

• Is it about transport that uses proteins to help move molecules across the membrane? 

• Or is it about movements of substances through a membrane? 

• Could it be when molecules spread from High to Low concentration on their own? 

• Or is it when pressure pushes something through a membrane?
