What is the function of cilia in certain cells?
Press to flip
Cilia are hair-like projections that trap particles and expel them, such as in the respiratory tract.
How does the cell wall benefit plant cells?
The cell wall provides shape, support, and protection to plant cells.
Describe the primary function of ribosomes.
Ribosomes synthesize proteins.
Why are mitochondria often referred to as the 'powerhouse of the cell'?
Mitochondria are the site of cellular respiration, producing ATP for energy.
Explain the function of vacuoles in plant cells.
Vacuoles, particularly the central vacuole in plant cells, store water and other substances.
Differentiate between Rough ER and Smooth ER in terms of their functions.
Rough ER is involved in protein transport and has ribosomes attached, while Smooth ER is involved in lipid synthesis and detoxification and does not have ribosomes attached.
Describe the function of flagella in some cells.
Flagella are tail-like structures that aid in cell movement, like in sperm cells and certain bacteria.
What is the primary function of lysosomes?
Lysosomes contain enzymes that break down damaged or worn-out cell parts.
What is the function of the Golgi Apparatus in a cell?
The Golgi Apparatus modifies, packages, and transports proteins into usable forms.
What are the three common components found in all cells?
Cell membrane, cytoplasm, and DNA.
List two organelles that are found in both plant and animal cells.
Mitochondria and the nucleus are found in both plant and animal cells.
What is a key difference between eukaryotic and prokaryotic cells in terms of their genetic material?
In eukaryotic cells, the genetic material is contained within a nucleus, while in prokaryotic cells it is not.
What components make up the cytoskeleton of a cell?
The cytoskeleton is composed of microfilaments (protein threads) and microtubules (hollow tubes).
What role does the nucleolus play within the nucleus of a eukaryotic cell?
The nucleolus is responsible for making ribosomes.
What is the main function of chloroplasts in plant cells?
Chloroplasts are the site of photosynthesis and contain the green pigment chlorophyll.
