Unit 3 - Cells Flashcards
Be able to identify, label, and understand the function of the different parts of the microscope.
Know the different total magnifications and how to calculate them.
Know what FOV is and how to estimate the size of a sample given a known field of view.
Understand the rules and best practices of microscope use
- How to store and handle
- How to adjust and focus in on a sample
Know examples of each cell type (including what we observed in the microscope lab)
Which cell type are plants, animals, fungi, and protists?
Be able to explain how the nucleus is a key part of explaining the difference
You do not need to know all the organelles, but do need to know the key differences between plant and animal cells? Eukaryote and prokaryote?
What molecules make up the membrane? How are cells selectively permeable?
What is the role of protein channels?
What types of molecules need to pass across the cell membrane?
Which ones can pass freely? And which one cannot pass freely?
Does the diffusion process require energy?
Are simple and facilitated diffusion active or passive?
What is diffusion? Give a simple everyday example of diffusion.
What is osmosis? Why is it important? In what direction does water move?
What happens to animal and plant cells when placed in different concentrations and why?
Understand tonicity and be able to include hypertonic, isotonic, and hypotonic in your answer.
Indicate the direction of net water movement between two solutions.
What is a solution? What is a solute? What is a solvent? Give an example of each.
What is a concentration gradient? Be able to explain why and in what instance (simple, facilitated, or active) a molecule would move with (down) the concentration gradient or against (up) the concentration gradient.
What is ATP and how is it used in active transport?
Know how the sodium-potassium pump works as an example of active transport.
Do molecules just stop moving once equilibrium has been reached?
Be able to recap the key takeaways from the diffusion and osmosis lab.
Know the differences and similarities between simple diffusion, facilitated diffusion, passive transport, and active transport.
