OPENER

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!!!!!!!!!

THE CELL

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
