Parts of a cell Remember that we compared the parts of a cell to a city? To a school? Color the NAME the same color you choose to color in the organelle. For example, if you color in the word “nucleus” with blue, then also color in that portion of the cell in blue.

CELLS
10
Cell Membrane BOTH Plant and Animal Cells
Function: controls what substances enter and exit the cell Analogy to City: City “Gate Keeper”
11
Cell Wall PLANT CELLS ONLY
Function: surrounds plants to protect and support the cell Analogy to City: City Border
12
Nucleus BOTH Plant and Animal Cells
Function: directs all the cells activities (brain of cell) Analogy to City: City Hall
13
Nucleolus BOTH Plant and Animal Cells
Function: makes ribosomes inside the nucleus Analogy to City: Copy Machine Inside City Hall
14
Nuclear Membrane BOTH Plant and Animal Cells
Function: controls what enters and leaves the nucleus, protects Analogy to City: gate around City Hall
15
Chromosomes BOTH Plant and Animal Cells
Function: contains the important blueprints of the cell or DNA Analogy to City: City Mayor
16
Vacuole BOTH Plant and Animal Cells
Function: stores food, water, waste, and other materials Analogy to City: Warehouses, Water Towers, etc.
17
Chloraplast PLANT CELLS ONLY
Function: captures energy from sunlight and produces food Analogy to City: Solar Energy Plant
18
Endoplasmic Reticulum
BOTH Plant and Animal Cells Function: built proteins and move them throughout cell or out of cell (Smooth – no ribosomes, Rough – ribosomes) Analogy to City: City Transportation Department
19
Cytoplasm BOTH Plant and Animal Cells
Function: gel-like fluid between cell membrane and nucleus, allows other organelles to float freely through cell Analogy to City: City Yards
20
Ribosomes BOTH Plant and Animal Cells Function: produce proteins
Analogy to City: Construction Company
21
Lysosomes ANIMAL CELLS ONLY
Function: contain chemicals that break down food particles and worn out cell parts Analogy to City: Recycle or Waste Management Company
22
Mitochondria BOTH Plant and Animal Cells
Function: rod-shaped organelle that produce energy (powerhouse) Analogy to City: Energy Plant
23
Golgi Body BOTH Plant and Animal Cells
Function: receives materials from the endoplasmic reticulum and sends them to other parts of the cell Analogy to City: Post Office Post Office
24
The Whole City… Post Office

27
Euglena, Amoeba, Paramecium, and Volvox
Protists… Euglena, Amoeba, Paramecium, and Volvox
28
Amoeba Amoeba Pseudopod (fake foot) Nucleus
29
Euglena Nucleus Chloroplast Flagella Euglena
30
Paramecium Macro (big) and micro (little) nucleus Paramecium Cilia
31
Volvox Daughter colony Adult Colony Paramecium
32
Protists…Animal? Plant? Fungus?
Protists are a mix of organisms that don’t exactly fit into the animal, plant, or fungus kingdoms…and sort of fits into all of them! Protists are __________________ - which means they have a nucleus and other membrane bound organelles. The other category would be prokaryotic. What are we? eukaryotes
33
Protists Uni-cellular ____________________ - one celled organisms.
Some have animal – like qualities (_____________ means “first animal” in Greek) Some have plant-like qualities like _______________ Some are like fungi Protozoa Chlorophyll to use in photosynthesis
34
Protists – finding food
Those who can feed themselves with photosynthesis are called ________________ Those who must find food in the environment around them (or move to find food) are called ________________________. Autotrophs Heterotrophs
35
Protists - locomotion Some use a fake foot that they ooze outward to move, its called a … __________________ One example is the _____________________ Pseudopod Amoeba
36
Protists - locomotion Some have small, hair-like structures that come out of the membrane all over the organism… __________________ One example is the _____________________ Cilia Paramecium
37
Protists - locomotion Some use a whip-like tail known as a ____________________ One example of this is the __________________ Flagellum Euglena
38
Protists - locomotion Some work with each other – combining flagella and teamwork… One example is the _____________________ Volvox
39
Amoeba Some use a fake foot that they ooze outward to move, its called a … __________________ Single celled or ___________________ They must find food in the environment so they are ________________________________ They reproduce through _____________ which means they simply split into two cells. Pseudopod Uni-cellular Heterotrophs Fission Amoeba Feeds! Youtube link
40
Paramecium Some have small, hair-like structures that come out of the membrane all over the organism… __________________ Single-celled or ______________________ Collect food from the environment so they must be _____________________ Reproduce through ________________________ Cilia Uni-cellular Heterotrophs Asexual means most often, but sexual reproduction is possible, too Amazing Microscopic HD Video! Paramecium Feeding!
41
Euglena Some use a whip-like tail known as a ____________________ Single celled or ______________________ Can either use photosynthesis OR collect food from the environment so a ________________ Reproduces through _____________________ Flagellum Uni-cellular Auto / Heterotroph Fission EUGLENA: min 5:05 shows flagella fairly well
42
Volvox Plant-like Auto and heterotroph
Some work with each other – combining flagella and teamwork… Volvox is actually many cells but each is an individual organism – they simply live together in a colony for the ease of life. Contain chlorophyll so must be _______________ but can also collect NUTRIENTS from the environment so considered both ________________________________ Plant-like Auto and heterotroph
43
Volvox Each of the cells have two flagella and they must coordinate them to cause motion for the entire colony. They have a red “eye” spot that can help determine light. They work together but seem to have poles (so they know forward and back. The volvox colony will reproduce new cells through asexual reproduction, but also has the ability to go to sexual reproduction so two separate colonies would be needed. Volvox Dances! Volvox – showing flagella

Protist Web Adventure Name of Protist Amoeba Paramecium Gets food
Digests food Gets rid of waste Moves Oxygen Reproduces Surrounds the food Uses cillia to help ingest food (“sweep” it in) Also uses oral groove to catch food Slowly brings it into the cell to digest Digested by food vacuole Waste exits through a vacuole. Moves and leaves the waste behind. Released through anal pore Uses pseudopods Cilia Gets oxygen from water, soil, or other animals it lives on. From the water that it lives in. Through binary FISSION Sexual and Asexual as needed. Asexual is most common.
45
Protist Web Adventure Name of Protist Euglena Volvox Gets food
Digests food Gets rid of waste Moves Oxygen Reproduces Contains chloroplasts which have chlorophyll to produce their own food. Can also move to food Contains chlorophyll to produce its own food. Can also move to find food – mostly algae Digests by absorption through the cell surface (if outside source) Store food in vacuoles Through a vacuole Using specialized cells? Uses flagellum Flagellum and teamwork Gets oxygen from the fresh water or soil they live in. From the water that it lives in. Through binary FISSION Sexual OR Asexual as needed
