Structures In the Cell
DAILY DO NOW
Look at the picture to the right.
Using your notes from
yesterday, identify whether it is
a plant or animal cell. Give me
a minimum of 2 reasons why (2
pieces of evidence).
Review: so what
type of cell did
Charlie step on?
Organelle
Nucleus
Nucleolus
Mitochondria
Chloroplast
Ribosome
Organelle
Rough Endoplasmic
Reticulum
(E.R)
Smooth Endoplasmic
Reticulum
(E.R)
Golgi Apparatus/
Body
Vacuole
Lysosome
Type of Cell
(plant / animal/ both)
Function
Hint
Nucleus
•Only
Eukaryotic
Cells
oBoth plant
and animal
Structure
Function
Nucleus
1. Control center
2. Contains genetic material
(DNA/RNA)
3. Surrounded by nuclear
membrane (has pores)
What could a hint be?
Hint
• Analogy:
1. Brain of the cell
2. Principle
Nucleolus
oBoth plant
and animal
Structure
Function
Nucleolus
1. Inside of nucleus
2. Makes ribosomes
3. Contains genetic material
(DNA/RNA)
What could a hint be?
Hint
• Analogy:
• Principles computer
Nuclear Membrane
• Surrounds nucleus
• Made of two layers
• Openings (pores) allow
material to enter and
leave nucleus
Mitochondria
Plant and
animal
Structure
Function
Mitochondria
1. Provides Energy for the
Cell
2. Cellular Respiration
What could a hint be?
Hint
• Analogy:
1. Battery
2. “mighty
mitochondria”
Chloroplast
Plant
Structure
Function
chloroplast
1. Converts sunlight into
glucose (sugar, “food”)
2. Photosynthesis
3. Contain chlorophyll
for
photosynthesis
What could a hint be?
Hint
• Analogy:
1. Solar
panels
Ribosomes
Plant and
Animal
Structure
Function
ribosome
• Synthesis (make) proteins
Found:
1. Within cytoplasm
2. Attached to Rough ER
What could a hint be?
Hint
• Analogy:
1. Construction
workers
2. Builders
Rough Endoplasmic Reticulum
(RER)
Plant and
Animal
Structure
Function
Rough
Endoplasmic
Reticulum (RER)
1. Transports material
around the cell
2. Prepares proteins for
export
3. Contains ribosomes
What could a hint be?
Hint
• Analogy:
1. Hallways
Smooth Endoplasmic Reticulum
(RER)
Plant and
Animal
Structure
Function
Smooth
Endoplasmic
Reticulum (RER)
1. Transports material
around the cell
2. Synthesis (makes) lipids
(fats)
3. NO ribosomes
What could a hint be?
Hint
• Analogy:
1. Cafeteria Workers
B
A
Golgi Bodies / Apparatus
Plant and
Animal
Structure
Function
Golgi Bodies
1.Collects, modifies,
packages and distributes
proteins and lipids
2.Move material into and
out of the cell
3.Flattened stacks
What could a hint be?
• Collects, modifies, packages and distributes
Hint
• Analogy:
1. Post Man
2. UPS
Vacuole
Plants: large
Animals: many
small
Structure
Function
Vacuole
1. Storage center
2. Contains water
• Helps plants to
maintain shape
What could a hint be?
Hint
• Analogy:
1. Vacuum
2. Water balloon
Lysosome
Animal
Structure
Function
Lysosome
1.Destroy cells or foreign
matter
2.Contains digestive
enzymes to digest food
s or destroy aging
organelles
What could a hint be?
•Lysis: to breakdown
Hint
• Analogy:
1. Lysol
2. Trashcan
3. Garbage disposal
