Human Eukaryotic Flashcards
What is a eukaryotic cell?
A eukaryotic cell is a type of cell that has a nucleus and membrane-bound organelles.
True or False: Eukaryotic cells are larger than prokaryotic cells.
True
What organelle is responsible for energy production in eukaryotic cells?
Mitochondria
Fill in the blank: The _______ is the control center of the eukaryotic cell.
nucleus
What is the function of the endoplasmic reticulum?
The endoplasmic reticulum synthesizes proteins and lipids.
Where are ribosomes primarily located in a eukaryotic cell?
On the rough endoplasmic reticulum and free-floating in the cytoplasm.
Which organelle is involved in the modification and packaging of proteins?
Golgi apparatus
True or False: Lysosomes are known as the ‘digestive system’ of the cell.
True
What is the primary function of the plasma membrane?
To protect the cell and regulate the movement of substances in and out.
Which organelle contains enzymes for breaking down waste materials?
Lysosomes
What is the role of the cytoskeleton in eukaryotic cells?
The cytoskeleton provides structural support and aids in cell movement.
Fill in the blank: The _______ is the site of photosynthesis in plant cells.
chloroplast
What structure provides rigidity to plant cells?
Cell wall
Which organelle is involved in the synthesis of ATP?
Mitochondria
What is the function of peroxisomes?
To break down fatty acids and detoxify harmful substances.
True or False: The nucleolus is responsible for ribosome production.
True
What is the function of vacuoles in plant cells?
To store nutrients and waste products.
Where is the genetic material located in eukaryotic cells?
In the nucleus
Which organelle is responsible for lipid synthesis?
Smooth endoplasmic reticulum
Fill in the blank: The _______ is the network of protein filaments that helps maintain cell shape.
cytoskeleton
What is the primary role of the plasma membrane?
To act as a barrier and control the entry and exit of substances.
What organelle is known as the ‘powerhouse of the cell’?
Mitochondria
True or False: Chloroplasts are found in animal cells.
False
What is the function of the Golgi apparatus?
To modify, sort, and package proteins for secretion.
Which organelle is involved in detoxification processes?
Peroxisomes
Where does protein synthesis occur in eukaryotic cells?
Ribosomes
What is the function of the cell wall?
To provide structural support and protection in plant cells.
Fill in the blank: The _______ is a double-membrane organelle that contains the cell’s DNA.
nucleus
