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?
3
NORM As a class, we will work towards this We ask questions to help us understand
4
Agenda Do Now Book Keeping Organelle Function Organelle Structure Wrap Up
5
Book Keeping Classroom Policy Change Study Sessions After School
6
Organelles Defn: Structures within a cell that performs a specific function Like tiny organs for a cell Think of our cell as a factory
7
OrganelleFunction Eukaryotic cell organelles (structure / function)
8
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
9
Control center of cell (controls all cellular activities) Contains DNA Contains nucleolus Nucleus
10
Nucleolus Located inside of the nucleus Contains RNA and proteins Makes ribosomes
11
Nuclear membrane/ Nuclear envelope Double-layered membrane enclosing the nucleus of a cell.
12
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
13
Endoplasmic Reticulum Helps move substances within cells Network of interconnected membranes Two types Rough endoplasmic reticulum Smooth endoplasmic reticulum
14
Rough Endoplasmic Reticulum Ribosomes attached to surface Manufacture proteins Not all ribosomes attached to rough ER May modify proteins from ribosomes
15
Smooth Endoplasmic Reticulum No attached ribosomes Has enzymes that help build molecules Carbohydrates Lipids
16
Golgi Apparatus Involved in packaging and secretion of proteins The cellular post office Also called golgi body
17
Mitochondria Where energy for the cell is made (ATP) Site of cellular respiration
18
Lysosomes Found in animal cells Digest and recycle worn out cell parts Destroy foreign invaders
19
Plant cell only Large vacuoles for storage of water and sugars Cell wall made of cellulose for support and protection Chloroplasts Where photosynthesis happens (glucose is made from water, CO2, & sunlight) Filled with chlorophyll, which gives green color
20
Cytoplasm Viscous fluid containing organelles Components of cytoplasm Interconnected filaments & fibers Fluid = cytosol Organelles
21
Cytoskeleton Made of 3 fiber types Microfilaments Microtubules Intermediate filaments 3 functions: mechanical support anchor organelles help move substances
22
Cilia & Flagella Provide motility Cilia Short, hair-like extensions Flagella Whip-like extensions
23
Centrioles Pairs of microtubular structures Play a role in cell division
24
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
25
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?
26
Self-Assess LT (5 minutes) BAME I 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
27
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
