$10 Microscopes What is the magnification of a 10X eyepiece and a 40X objective? Who first coined the word “cells?” ANSWER: 400 X Hooke
$20 Microscopes If the field diameter was 4 mm, how many µm would that be? nm? ANSWER: 4,000 µm How many nm? 4,000,000
$30 Microscopes (3) What type of microscope would view an organism 2500 X’s and its internal structures? Type of microscope to view atoms? Who made the first microscope? ANSWER: TEM SPM Leeuvenhoek
$40 Microscopes What term means “clarity, or being able to distinguish two objects as separate?” What term means the objectives will stay in focus if you just turn the revolving nosepiece? ANSWER: resolution (or resolving power) parfocal
$50 Microscopes What is the size of this organism? (mm + µm) What is the field diameter? ANSWER: 0.5 mm or 500 µm F.D. = 1.5 mm
OSMOSIS APPLICATION Go back to your lab table and look at the potatoes. Write answer to question #3. (Which is crisp and which is saggy?)
$60 Microscope Describe how to prepare a wet mount: (pic next slide) ANSWER: 1. object on slide 2. Drop of water on slide 3. Cover slip on water and object.
$70 Microscopes Show where these are on a compound light microscope: stage Condenser Iris diaphragm Coarse adjustment Fine adjustment
$10 Nicknames What organelle would be known as “the genetic control center?” ANSWER: nucleus
SNEAKER: WHAT DOES “in equilibrium” mean? ANSWER: concentration of solute is the same throughout the solution
$20 Nicknames (2) What organelle is the powerhouse of the cell? What structure of the plasma membrane is for identification markers? ANSWER: mitochondrion ANSWER: carbohydrate chains
$30 Nicknames (3) What could be called the “ribosome factory?” What is the name of movment in and out of the plasma membrane that uses ATP? Do prokaryotes contain membraned-bound organelles like eukaryotes? ANSWER: nucleolus ANSWER: active transport ANSWER: no
$40 Nicknames (2) What organelle means “network of channels within a cell?” What are two other names for the cell membrane? ANSWER: Endoplasmic reticulum ANSWER: plasma membrane Phospholipid bilayer
$50 Nicknames (2) What organelle means “breakdown body” or “clean-up crew?” How is osmosis and diffusion different? ANSWER: lysosome ANSWER: osmosis is water moving through a selectively permeable membrane
$60 Nicknames(2) What could be called ”pita bread shaped warehouse and finishing factory?” Describe “receptor-mediated endocytosis.” ANSWER: Golgi apparatus ANSWER: indentation of plasma membrane has receptors that fill and fall into the cytoplasm as a food vacuole
$70 Nicknames What would be called in a cell: (A) the supportive meshwork of fine fibers AND (B) the “solar power system?” ANSWER: (A) cytoskeleton (B) chloroplasts
Cell Structure and Function Matching P. Has enzymes )
$10 Picture It What is this in the cell picture? ANSWER: Golgi apparatus
$20 Picture It How could you tell the difference between ER and Golgi in a cell picture? ANSWER: ER is connected and Golgi are not connected stacks
$30 Picture It How could you tell differences between mitochondria and chloroplasts? ANSWER: mitochondria have wavy inner membrane and chloroplasts have green stacks
$40 Picture It Draw a red blood cell in a hypertonic solution. Draw the arrows of the flow of water. Identify the hypertonic and the hypotonic solutions.
$50 Picture It How would you tell the difference in a cell diagram among: –Vacuoles –Lysosomes –Ribosomes?

$60 Picture It What are these structures in the bacterial picture? A,B,C (answers next slide)
$60 Picture It What are these structures in the bacterial picture? A,B,C A-Capsule - sticky B-Cell wall-thick, stiff C-plasma memb.-thin
What two structures of the prokaryote help it stick to the surface? Capsule (A) Pili (I)
