Prokaryotic cells
What does the prefix "pre" mean?
The prefix "pre" means before.
On top of having a nucleus, eukaryotic cells also have __________-___________ __________________ that prokaryotic cells do not.
On top of having a nucleus, eukaryotic cells also have membrane-bound organelles that prokaryotic cells do not.
What is the difference between the structures of the smooth endoplasmic reticulum (SER) and the rough endoplasmic reticulum (RER)?
The RER has ribosomes on it and the SER does not
How many characteristics of life are there?
There are 8 characteristics of life.
Look at both types of cells. Which cell is the prokaryotic cell?
the one with the gray background
There are some cell parts that are specific to prokaryotic cells and others that are specific to eukaryotic cells. What is the MAIN difference between PROkaryotic and EUkaryotic cells?
Eukaryotic cells have a nucleus and prokaryotic cells do not.
List at least 3 organelles that are only found in eukaryotic cells.
-SER / RER
-Nucleus / Nucleolus
-Cytoskeleton
-Mitochondria
-Peroxisome
-Golgi Body
-Lysosome
The ____________ is made up of filaments and tubules and helps shape and support the cell. It also helps things move around in the cell.
The cytoskeleton is made up of filaments and tubules and helps shape and support the cell. It also helps things move around in the cell.
Sensitivity (movement)
What are the 3 cell parts that are found in BOTH prokaryotic cells AND eukaryotic cells?
1. Plasma membrane
2. Ribosomes
3. Cytoplasm / cytosol
What are the 4 cell parts that are only found in prokaryotic cells?
1. Pilus
2. Flagellum
3. Capsule
4. Nucleoid
Which organelle packages the energy from the food you eat into ATP molecules and is considered to be the powerhouse of the cell?
What is the organelle in eukaryotic cells that is responsible for sorting and correctly shipping the proteins?
Golgi Body
A. Structure
B. Function
C. Life-span
D. None of the above
D. None of the above.
Cells are all different shapes and sizes. The structure of a cell determines its function. Some cells live for a very long time and some rapidly die and are replaced.
What number(s) correctly labels the nucleolous?
11
Flagella perform what function for prokaryotic cells?
Flagella are tails attached to the main body of a cell that can rotate to move the cell forward.
The organelle where photosynthesis takes place is also one thing that differentiates plant and animal cells. What is this organelle called?
Chloroplast
State the shared function of both ribosomes and the rough endoplasmic reticulum.
Proteins are synthesized by ribosomes and the rough endoplasmic reticulum.
Chloroplasts and mitochondria are two organelles that are involved in performing which characteristic of life?
Use of energy
-Chloroplasts convert light energy into chemical energy (glucose)
-Mitochondria break down glucose to make ATP
What number(s) correctly labels the nucleoid?
5
Prokaryotic cells ALWAYS make up what kind of organisms?
Prokaryotic cells always make up unicellular organisms.
Give 2 examples of multicellular organisms that are made up of eukaryotic cells.
1. Animal cells
2. Plant Cells
3. Fungal Cells
When comparing a cell to a cup of Boba (bubble tea), what represents the cytoplasm/cytosol?
The cytoplasm is the gelatinous liquid that fills the inside of a cell, so all the liquid in the cup (not the plastic cup, lid, straw, or bubbles) is what represents the cytoplasm/cytosol.
The plasma membrane can be found surrounding both prokaryotic and eukaryotic cells. What characteristic of life does the function of the plasma membrane demonstrate?
Maintain homeostasis (a stable internal environment)
What number(s) correctly labels the plasma membrane?
4 AND 20
