Warm Up
What makes something living?Hint: must meet 4 qualities…
What are the two types of organisms?Hint: one or many cells???
What are the two types of cells?Hint: nucleus or no nucleus???
What is the cell theory about?Hint: we know 3 things about cells…
Inside a Cell!
Introduction to cell organelles
Cell Theory ReviewThree main points to the cell theory:
All living things are composed of cellsCells provide structure and carry on
major functions to sustain lifeOrganisms (living things) can be single cell
(unicellular) or made of many cells (multicellular)
Cell function is similar in all living things
What’s inside you?
What’s inside a cell?
Organelles – parts inside of a cell that have specific functions
Welcome to CLUB CELL!!!
What type of club is it?
Nucleus
FUNCTIONControls the cell
and contains its genetic material (DNA)
Nucleus
ANALOGYThe nucleus is like
the CLUB OWNER because they control what happens in the club.
Cell Membrane
FUNCTIONa semi-
permeable barrier of the cell that lets materials in or out
Cell Membrane
ANALOGYThe cell
membrane is like a BOUNCER because it only lets certain things in or out
Mitochondria
FUNCTIONTo process
nutrients and oxygen into energy
Mitochondria
ANALOGYThe mitochondria
are like a DJ because they play music to give the club energy
Lysosome
FUNCTIONTo digest and
break down materials in the cell
Lysosome
ANALOGYThe lysosomes are
like HUNGRY PEOPLE. They have one purpose: to digest!
Cytoplasm
FUNCTIONThe fluid that
fills the cell
Cytoplasm
ANALOGYThe cytoplasm
is like THE CROWD during crowd surfing.
Vacuoles
FUNCTIONTo store
materials for the cellEx: nutrients,
water, waste, etc.
Vacuole
ANALOGYThe vacuoles are
like CLOSETS. They can be used to store many things.
Endoplasmic Reticulum
FUNCTIONTo store,
package, and move materials needed to make proteins
Endoplasmic Reticulum
ANALOGYThe E.R. is like an “IN” WAITER because it packages orders
Ribosomes
FUNCTIONTo build
proteins for the cell and organism
Ribosomes
ANALOGYThe ribosomes are
like CHEF because they combine simple ingredients to make complex dishes (proteins)
Golgi Bodies
FUNCTIONProcesses
protein packages and sends them where they are needed
Golgi Bodies
ANALOGYThe Golgi Bodies
are like an “OUT” WAITER because they take the dishes (proteins) where they are needed

Main Idea Web
Organisms can be classified by their cell type.
Main Idea Web
Molecular Biology8.L.5 Understand the composition of various substances as it relates to their ability to serve as a source of energy and building materials for growth and repair of organisms.
8.L.5.1 Summarize how food provides the energy and the molecules required for building materials, growth and survival of all organisms (to include plants).
8.L.5.1 Food provides molecules that serve as fuel and building material for all organisms. Organisms get energy by oxidizing their food, releasing some of its energy as thermal energy. All organisms are composed of cells-a group of organelles working together. Most organisms are single cells; other organisms, including humans, are multi-cellular. Cells carry on the many functions needed to sustain life. They grow and divide (mitosis or meiosis), thereby producing more cells. This requires that they take in nutrients, which they use to provide energy for the work that cells do and to make the materials that a cell or an organism needs. Cell (Plasma) membrane is selectively permeable, controlling what enters and leaves the cell. Sugars to produce energy for the cell are broken down in a process that uses oxygen and produces carbon dioxide and water. Cells lacking internal membrane-bound structures are called prokaryotic cells. The cells of most unicellular organisms such as bacteria are prokaryotes. Cells that contain membrane-bound structures are called eukaryotic cells. Most of the multi-cellular plants and animals we know have cells containing membrane-bound structures and are therefore called eukaryotes. The membrane-bound structures within eukaryotic cells are called organelles. Each organelle has a specific function for cell survival.
