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?


Opener

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

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!!!!!!!!!

Opener

Water

Chemical Formula for water is H2O

Water molecules are held together by hydrogen bonds

Water is a polar molecule

Polar molecule – molecule with unbalanced charges. Partially positive end and partially negative end

Nonpolar molecule – molecule with balanced charges


Opener

Solutions

Solution – 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

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.


Opener

pH

pH is a measure of the acidity or basicity of an aqueous solution.

Water breaks down into H+ and OH-

BASE

ACID

More H+ in the solution

More OH- in the solution


Opener

Water and pH in Living Organisms

Homeostasis– the body maintaining a constant internal environment in a changing external environment.

  • Regulated Conditions

  • Temperature

    • Water volume

    • pH

    • Glucose concentration

    • Salt concentration

Internal organization

Internal Organization

  • Eukaryotic cells contain organelles.

    • Specialized structures within the cell that perform specified functions for the cell.


Thursday opener

THURSDAY OPENER

  • Create a Venn Diagram comparing prokaryotes and eukaryotes

  • Prokaryotes Eukaryotes

BOTH


Thursday cell organelles and functions

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

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 cards1

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 membrane

Plasma (Cell) Membrane

  • The boundary of the cell.

  • Two layers of phospholipids and one layer of protein.

  • Allows different substances in and out of the cell


Opener

CYTOPLASM

Gel-like substance residing inside the cell membrane holding all the cell's organelles in place


The nucleus

The Nucleus

  • Houses the DNA

  • Has pores to let the RNA leave

  • Center of the nucleus is a nucleolus = makes ribosomes


Ribosomes

Ribosomes

  • Small non-membrane bound organelles.

  • Makes proteins

  • Can be free or attached to ER


Endoplasmic reticulum

ENDOPLASMIC RETICULUM

  • Complex network of transport channels.

  • Two types:

  • Smooth- ribosome free and functions in poison detoxification.

  • Rough - contains ribosomes and releases newly made protein from the cell.

Smooth Endoplasmic Reticulum


Golgi apparatus

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

Lysosomes

  • Help digest waste inside the cell.


Centrioles

Centrioles

Found only in animal cells

Helps build cilia and flagella

Helps cell divide


Cytoskeleton

Cytoskeleton

  • Acts like a skeleton and gives the cell its shape.


Mitochondrion

MITOCHONDRION

  • Produces the cells energy compound, ATP


The chloroplast

THE CHLOROPLAST

  • Contains chlorophyll (green pigment)

  • Found only in plants and algae.

  • Captures light so the plant can photosynthesis


Cilia and flagella

Cilia and Flagella

Cilia: short hair like projections used by animal cells for movement

Flagella: a tail-like projection used for locomotion.


Pseudopod

Pseudopod

  • A temporary projection of the cytoplasm of certain cells.

  • Phagocytes – used for engulfing cells

  • Unicellular organisms, especially amoebas -serves in locomotion


The vacuole

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

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
