Do Now (Seriously though, 5 minutes)

Title: Organelles Pt. 2

Write in LT, BAME, Evidence, and How I can Improve

DO NOW:

A mystery cell has a cell wall. What additional

evidence would you need to determine if the cell

is prokaryotic or eukaryotic?

NORM

As a class, we will work towards this

We ask questions to help us understand

Agenda Do Now Book Keeping Organelle Function Organelle Structure Wrap Up

Book Keeping Classroom Policy Change

Study Sessions After School

Organelles

Defn: Structures within a cell that performs a specific function

Like tiny organs for a cell

Think of our cell as a factory

Organelle Function

Eukaryotic cell organelles (structure / function)

Plasma (cell) Membrane

Gate Keeper”

Physical & chemical boundary of all cells

A double layer called the phospholipid bilayer. It is selectively permeable (semipermeable) meaning only

certain things are let in and out

Control center of cell (controls all cellular activities)

Contains DNA

Contains nucleolus

Nucleus

Nucleolus

Located inside of the nucleus

Contains RNA and proteins

Makes ribosomes

Nuclear membrane/ Nuclear envelope Double-layered

membrane enclosing the nucleus of a cell.

Ribosomes Sites of protein synthesis

Proteins are the main product produced by the cell

Not considered a membrane-bound organelle

Found in prokaryotes and eukaryotes

Endoplasmic Reticulum Helps move substances within cells

Network of interconnected membranes

Two typesRough endoplasmic reticulumSmooth endoplasmic reticulum

Rough Endoplasmic Reticulum Ribosomes attached to surface

Manufacture proteinsNot all ribosomes attached to rough ER

May modify proteins from ribosomes

Smooth Endoplasmic Reticulum No attached ribosomes Has enzymes that help build molecules

CarbohydratesLipids

Golgi Apparatus Involved in packaging and secretion of proteins

The cellular post office

Also called golgi body

Mitochondria Where energy for the cell is made (ATP) Site of cellular respiration

Lysosomes Found in animal cells

Digest and recycle worn out cell partsDestroy foreign invaders

Plant cell only Large vacuoles for storage of

water and sugars

Cell wall made of cellulose for support and protection

ChloroplastsWhere photosynthesis happens

(glucose is made from water, CO2, & sunlight)

Filled with chlorophyll, which gives green color

Cytoplasm Viscous fluid containing organelles

Components of cytoplasmInterconnected filaments & fibers Fluid = cytosolOrganelles

Cytoskeleton Made of 3 fiber types

MicrofilamentsMicrotubulesIntermediate filaments

3 functions: mechanical support anchor organelles help move substances

Cilia & Flagella Provide motility

Cilia Short, hair-like

extensions

Flagella Whip-like extensions

Centrioles Pairs of microtubular structures Play a role in cell division

Matching Organelle to its Function

Working with your elbow partner

Cut out the Functions and Memory Items

Match the function and memory item with the correct organelle

You BOTH must agree before you glue them on

We ask questions to understand Think about the learning targets we have

investigated

What questions do you have?

Should I address these in class?

Should I address these afterschool?

Self-Assess LT (5 minutes)

B A M EI have little to

no understanding of the learning

target.

I have some understanding of the learning

target.

I have a solid understanding of the learning

target.

I have a solid understanding of the learning

target and I am able to

help my peers have a solid

understanding

Wrap Up

Coming Up Cell Structure (Organelles) Work with Microscopes

Important Reminders Lab Safety Contract! Quiz on Microscopes, 8 Characteristics of

Living Things, and Cells on Friday 10/16/2015
