Day 5 pH, Biology Vocab, and The Cell
Assessment:
pH Scale
-The pH scale is a way of measuring how many Hydrogen ions (H+) are released when a molecule is dissolved in water (we call a solution of water, aqueous)
Watch this video on the pH scale. (Online Course instructions only) Create a box in your sketchbook, title it "pH scale" and take notes, write down questions you might have, and new examples you might think of. You may include any picture you like that represents the topic, including funny memes.
-An Acid is something that releases H+ ions when it is added to water
-A Base is something that releases OH- ions when added to water
-A buffer is something that releases the opposite ion causing the base or acid to become neutralized.
-Hydrophobic-is something that does not mix with water (Afraid of water)
-Usually because the molecule has no charge
-Hydrophilic- is something that mixes with water (Attracted to water)
-Usually because the molecule is polar

Assignment:
In your sketchbook you need to define all of these words. The definitions can be from a book or they can be in your own words. The definitions have to be hand written. There are 32 words, you need to have at least 10 images. (You can choose which 10 words to illustrate)

Cells
There are two types of cells in the world
-Prokaryotes
-Prokaryotes have no nucleus and no double membrane inclosed organelles
-All prokaryotes are single celled organisms. A prokaryote cannot be multicellular
-Bacteria and Archaea are the only prokaryotes
-If it is not a Bacteria or an Archaea then it is an Eukaryotic cell
-Eukaryotes
-Have a nucleus that contains all the genetic information (DNA)
-Eukaryotic cells have double membrane inclosed organelles
-Eukaryotes can be single celled organisms or multicellular organisms
Assignment:
You need to draw and label a cell and include a description of what each of these organelles do.
Organelles (You do not have to define these organelles but you do need a word or two describing what their function is)
Golgi Apparatus
Nucleus
Plasma Membrane
Mitochondria
Endoplasmic Reticulum
Smooth
Rough
Ribosomes
Cytoplasm
Cytoskeleton
Vacuole
Chloroplast
Cell Wall
Flagella
Cilia
This video will help you with you organelle descriptions.
Here is a fully labeled animal cell to guide your drawing.
Cell Theory
-Every living organism is made up of one or more cells
-The smallest living organisms are single cells, and cells are the functional units of multicellular organisms
-All cells arise from preexisting cells
