Have you ever wondered why flamingos are pink or orange? You've probably heard it has something to do with what flamingos eat, but do you know what exactly it is that produces the color?
Flamingos are pink or orange or white depending on what they eat. Flamingos eat algae and crustaceans that contain pigments called carotenoids. For the most part, these pigments are found in the brine shrimp and blue-green algae that the birds eat. Enzymes in the liver break down the carotenoids into the pink and orange pigment molecules deposited in the feathers, bill, and legs of the flamingos. Flamingos that eat mostly algae are more deeply colored than birds that eat the small animals that feed off of algae. Captive flamingos are feed a special diet that includes prawns (a pigmented crustacean) or additives such as beta-carotene, otherwise they would be white or pale pink. Young flamingos have gray plumage that changes color according to their diet. People eat foods containing carotenoids, too. Examples include beta-carotene in carrots and lycopene in watermelon, but most people do not eat enough of these compounds to affect their skin color.
Tuesday Agenda Literacy objectives: Writing to take notes and explain
one’s thinking. Content Objective: TSWBAT compare prokaryotes and
eukaryotes and identify various organelles. Framework: Cells Agenda: 1. Collect animal cell labeling/attendance and opener. 2. Cell PPT/cells diamond foldable 3. Closer: cell city and for homework create your own
analogy 4. 3D cell due Friday!!!!!!!!!

WaterChemical Formula for water is H2O
Water is a polar moleculePolar molecule – molecule with unbalanced charges. Partially positive end and partially negative end Nonpolar molecule – molecule with balanced charges
Water molecules are held together by hydrogen bonds
Hydrophobic – repelling, tending not to combine with, or incapable of dissolving (insoluble) in water.
Hydrophilic - having an affinity for (loving) water; readily absorbing or dissolving (soluble) in water.
SolutionsSolution – a homogeneous mixture of two or more substances
Solute – the substance dissolved in a given solution.
Solvent - a substance that dissolves another to form a solution
pHpH is a measure of the acidity or basicity of an aqueous solution.
More H+ in the solution
More OH- in the solution
Water breaks down into H+ and OH-
ACID BASE

THURSDAY: CELL ORGANELLES AND FUNCTIONS
Literacy objectives: Writing to take notes
and explain one’s thinking
Content objective: TSWBAT understand
how the cell organelles function
Agenda: Opener Attendance 3D cells are DUE
TOMORROW!!!!!!! Cell organelle ppt
CREATE TRADING CARDS VENN
DIAGRAMS/organelles function worksheet for homework
CLOSER: word splash
TRADING CARDS
1. You will need 16 note-cards. 2. Your notes-cards need to have one hole
punched in the upper right hand corner. 3. You will take notes on your cards. 4.The front of the card will have the name of the
organelle and a picture The back will have the function of the organelle
TRADING CARDS
FRONT: MITOCHONDRIA
BACK: (function)
Mitochondria are rod-shaped organelles that can be considered the power generators of the cell, converting oxygen and nutrients into adenosine triphosphate (ATP).
PLASMA (CELL) MEMBRANEThe boundary of
the cell.Two layers of
phospholipids and one layer of protein.
Allows different substances in and out of the cell
CYTOPLASM
Gel-like substance residing inside the cell membrane holding all the cell's organelles in place
THE NUCLEUSHouses the DNAHas pores to let the RNA leave
Center of the nucleus is a nucleolus = makes ribosomes
RIBOSOMES
Small non-membrane bound organelles.
Makes proteins Can be free or attached to
ER
ENDOPLASMIC RETICULUM
Complex network of transport channels.
Two types: 1. Smooth- ribosome
free and functions in poison detoxification.
2. Rough - contains ribosomes and releases newly made protein from the cell.
Smooth Endoplasmic Reticulum
GOLGI APPARATUS A series of flattened
sacs that modifies, packages, stores, and transports materials out of the cell.
Works with the ribosomes and Endoplasmic Reticulum.
LYSOSOMES
Help digest waste inside the cell.
CENTRIOLES
Found only in animal cells
Helps build cilia and flagella
Helps cell divide
CYTOSKELETON
Acts like a skeleton and gives the cell its shape.
MITOCHONDRION
Produces the cells energy compound, ATP
THE CHLOROPLAST
Contains chlorophyll (green pigment)
Found only in plants and algae.
Captures light so the plant can photosynthesis
CILIA AND FLAGELLA
Cilia: short hair like projections used by animal cells for movement
Flagella: a tail-like projection used for locomotion.
PSEUDOPOD
A temporary projection of the cytoplasm of certain cells. •Phagocytes – used for engulfing cells• Unicellular organisms, especially amoebas -serves in locomotion
THE VACUOLE Sacs that help in food
digestion or help the cell maintain its water balance.
Found mostly in plants and protists.
Plants have large central vacuole for water storage.
CELL WALL Extra structure surrounding the plasma
membrane in plants, algae, fungi, and bacteria. Plants - Made of Cellulose Fungi - Made of Chitin Bacteria - Made of Peptidoglycan Algae – Varied components
