Cell Organelles #1
Name the organelle that controls cell activities.
nucleus.
What is ATP?
The energy molecule for cell processes.
What are cilia and flagella used for?
Movement.
What is the function of lysosomes?
They break down and recycle cellular materials.
What macromolecule is the cell membrane mostly composed of?
Chlorophyll makes plants what color?
green
What do ribosomes do
Build proteins
Which organelle makes ATP?
Mitochondria
What is the function of the cytoskeleton?
Gives shape and supports movement.
Where is DNA found in a prokaryotic cell?
Floating in the cytoplasm.
Differentiate between Rough ER and Smooth ER.
Rough ER has ribosomes and makes proteins; Smooth ER makes lipids and removes toxins.
Name the two main types of cells.
Prokaryotic and Eukaryotic cells.
What are chromosomes made of
DNA
What do chloroplasts do?
Use sunlight to make food (glucose).
How do cytoplasm and cytoskeleton work together?
Cytoplasm fills space; cytoskeleton provides structure.
Where is DNA found in a eukaryotic cell?
Inside the nucleus.
What is the function of the Golgi apparatus?
It packages and sends proteins around the cell using vesicles.
These produce proteins for the cell
Ribosomes
Differentiate rough ER and smooth ER.
Rough ER makes proteins; smooth ER makes lipids & detoxifies.
Why do plants need both mitochondria and chloroplasts?
To make and then use
How does cell shape relate to function?
Shape matches job
Write the word equation for photosynthesis.
Carbon dioxide + water + sunlight → glucose + oxygen.
What is the name of the structures that make up the cell membrane?
Phospholipids
How is the cell membrane different from the nuclear envelope?
The cell membrane surrounds the whole cell; the nuclear envelope surrounds only the nucleus.
Why is the nucleus called the control center? | It stores DNA and directs all cell activities. |
| It stores DNA and directs all cell activities. |
How does energy flow from sun → chloroplast → mitochondrion?
Sunlight → glucose → ATP for cell work.
Example of a cell structure helping desert plants.
Thick cell walls reduce water loss.
If photosynthesis stops, what will happen to the oxygen level in the air?
It will decrease.
Write the equation for cellular respiration.
Glucose + oxygen → carbon dioxide + water + energy (ATP).
How does the shape of a red blood cell help its job?
Its disc shape lets it move easily through small blood vessels and carry oxygen.
