Organelles
Which organelle can be thought of us a storage tank?
a vacuole
Which organelles can be thought of as protein factories?
ribosomes
Which organelle allows plants to grow tall by providing structure?
a cell wall
These organelles, found mostly in animal cells, contain digestive enzymes that clean up and get rid of waste.
A. ribosomes
B. lysosomes
C. chloroplasts
D. mitchondria
B. lysosomes
List 2 organelles that are found in plant cells but not animal cells.
chloroplast
cell wall
or large central vacuole
These organelles supply the cell with its energy by breaking down sugars.
mitochondria
Which organelles is like the control center (the brain)?
the nucleus
Order the levels of organization from smallest to largest.
body system, cell,organism, tissue, organ, organelle
organelle, cell, tissue, organ, body system, organism
This organelle directs all cellular activities; it instructs the rest of the cell
what to do and control movement, reproduction, and eating.
A. nucleus
B. nucleolus
C.. endoplasmic reticulum
A. nucleus
Chloroplasts are responsible for photosynthesis, since animals do not produce their own food chloroplasts are not necessary.
What is the jelly-like filling found inside cells?
cytoplasm
Which organelle can be thought of as the outer skin of an animal cell?
the cell membrane
Why are nerve cells shaped differently than bone cells?
Which organelles do plant cells use to capture and store energy from sunlight using the process of photosynthesis?
A. chloroplasts
B. nuclei
C. mitochondria
A. chloroplasts
Which feature would you expect to see if you looked at a muscle cell under a powerful microscope?
Which organelle is on the outside of animal cells?
a cell membrane
This organelle is primarily responsible for combining molecules.
the Golgi apparatus
Provide an example of a one celled organism.
bacteria, protozoa, yeast
What makes rough endoplasmic reticulum rough and bumpy?
A. it has centrioles attached to it
B. it has vesicles that pinch off the edges
C. it has ribosomes attached to it
C. it has ribosomes attached to it
List 3 reasons why cells divide.
Growth – To allow an organism to increase in size by adding more cells.
Repair and Maintenance – To replace old, damaged, or dead cells.
3. Reproduction – In single-celled organisms, cell division is a form of reproduction (binary fission in bacteria, mitosis in eukaryotes).
Which organelle is responsible for aiding in cell division?
centrioles
A small membrane-bound organelle that stores fluid and dissolved substances. The cell membrane folds to create pockets.
pinocytotic vesicle
Regardless of type, all cells share these four features:
Cell membrane – A protective barrier that controls what enters and exits the cell.
Cytoplasm – A jelly-like fluid inside the cell where organelles are suspended.
DNA (Genetic Material) – Instructions for the cell's functions and reproduction.
4. Ribosomes – Small structures that produce proteins needed for the cell to function.
Which organelle is responsible for making ribosomes?
A. nucleolus
B. nucleus
C. Golgi apparatus
A. nucleolus
What is the difference between a prokaryote and a eukaryote? Include an organelle that is found in one but not the other and include reference to their sizes.
A prokaryote is a cell that lacks a nucleus and membrane-bound organelles, while a eukaryote is a cell that has a well-defined nucleus and multiple membrane-bound organelles; examples of prokaryotes include bacteria, while most animals, plants, and fungi are eukaryotes.
