Organelles quiz

Cell Membrane

• Found in all cells (prokaryotic and eukaryotic)
• External layer of the cell
• Important for controlling what goes in and out of the cell
• Crucial for maintaining homeostasis

Cell Wall

• Found in most prokaryotic cells and some eukaryotic cells (e.g., plant cells)
• Important for structural support
• Provides additional protection to the cell
• Helps maintain the cell's shape

Centrioles

• Found in eukaryotic cells (e.g., animal cells)
• Not found in plant cells
• Derived from the centrosome
• Two centrioles per centrosome
• Involved in cell division, specifically the formation of spindle fibers

Chloroplast

• Found in eukaryotic cells (e.g., plant cells)
• Not found in animal cells
• Responsible for photosynthesis
• Produces sugar

Cytoplasm

• Found in all cells (prokaryotic and eukaryotic)
• Everything inside the cell except for the nucleus in eukaryotic cells.
• Includes cytosol, a jelly-like substance.
• Supports the organelles along with the cytoskeleton

Endoplasmic Reticulum (ER)

• Found in eukaryotic cells (both plant and animal cells)
• Folded structure that acts as a highway for materials within the cell
• Plays a role in processing molecules
• Two types:
  • Rough ER: Contains ribosomes and makes proteins
  • Smooth ER: Makes lipids and is involved in detoxification
• Vesicles transport materials from the ER to other organelles

Golgi Apparatus

• Found in eukaryotic cells (both plant and animal cells)
• Acts like a packaging facility
• Modifies, sorts, and packages materials for delivery within the cell

Lysosome

• Found in eukaryotic cells (typically animal cells)
• Contains enzymes that break down substances
• Involved in digestion within the cell
• Potential for breaking down pathogens

Mitochondrion (plural: mitochondria)

• Found in eukaryotic cells (both plant and animal cells)
• Responsible for cellular respiration
• Produces ATP (adenosine triphosphate), the energy currency of the cell

Nucleus

• Found in eukaryotic cells (both plant and animal cells)
• Contains the cell's DNA
• Controls the cell's activities

Ribosome

• Found in all cells (prokaryotic and eukaryotic)
• Responsible for protein synthesis

Vacuole

• Found in eukaryotic cells (both plant and animal cells)
• Stores materials depending on the cell type
• Large central vacuole in plant cells
• Smaller, multiple vacuoles in animal cells
• Stores water, proteins, and waste products.

Test your knowledge on the various components of cells, including the cell membrane, cell wall, centrioles, chloroplasts, and cytoplasm. This quiz will assess your understanding of their structure, function, and significance in different types of cells.
