Vacuole
Chloroplasts contain the pigment chlorophyll, which captures light energy to convert carbon dioxide and water into glucose and oxygen. This process, known as photosynthesis, is essential for autotrophic nutrition in plants. Chloroplasts have a double membrane and internal thylakoid structures.
Which organelle is known as the powerhouse of the cell?
Chloroplast
Mitochondrion
Nucleus
Endoplasmic reticulum
Mitochondria generate ATP through oxidative phosphorylation, supplying energy for cellular processes. They have their own DNA and ribosomes, supporting the endosymbiotic origin theory. Their double membrane and cristae structure maximize energy production.
What is the jelly-like fluid that fills the cell and houses organelles called?
Cytoplasm
Nucleoplasm
Matrix
Periplasmic space
The cytoplasm is the gel-like substance enclosed by the cell membrane where organelles are suspended. It consists of cytosol, water, salts, and organic molecules. Cytoplasmic streaming helps distribute nutrients and organelles within the cell.
Which structure controls what enters and leaves the cell?
Cytoplasm
Nuclear envelope
Cell membrane
Cell wall
The cell membrane is a phospholipid bilayer with embedded proteins that regulate transport of molecules in and out of the cell. It maintains homeostasis and facilitates communication with the environment. Selective permeability is a key feature of the membrane.
Which organelle synthesizes proteins?
Lysosome
Golgi apparatus
Peroxisome
Ribosome
Ribosomes read mRNA sequences to assemble amino acids into polypeptide chains, forming proteins. They can be free in the cytosol or bound to the rough endoplasmic reticulum. Ribosomal structure includes a large and small subunit composed of rRNA and proteins.
What is the main function of the large central vacuole in plant cells?

Microtubules
Microtubules are cylindrical polymers of tubulin that form the main scaffold maintaining cell shape and serving as tracks for organelle movement. They also form the mitotic spindle for chromosome segregation.
Which organelle is involved in lipid synthesis and detoxification in animal cells?
Smooth endoplasmic reticulum
Rough endoplasmic reticulum
Golgi apparatus
Mitochondrion
The smooth ER lacks ribosomes and is the site of lipid and steroid hormone synthesis. It also detoxifies drugs and poisons in liver cells. Calcium ion storage in muscle cells occurs in the smooth ER known as the sarcoplasmic reticulum.
What is the primary function of the rough endoplasmic reticulum?
DNA replication
Protein synthesis and transport
Energy production
Lipid metabolism
The rough ER is studded with ribosomes that synthesize proteins destined for secretion or membrane insertion. It also transports these proteins via vesicles to the Golgi apparatus. Its structure provides a large surface area for translation.

Chromatin
Nuclear pore
Nuclear envelope
Nucleolus
The nucleolus is a dense region in the nucleus where rRNA genes are transcribed and ribosome subunits are assembled. It is not membrane-bound and disappears during mitosis. Its activity reflects the cell's protein synthesis demand.
How do vacuoles differ between plant and animal cells?
Plant cells have no vacuoles
Animal cells have no vacuoles
Both have identical vacuoles
Plant cells have a large central vacuole while animal cells have smaller and more numerous vacuoles
Plant cells typically feature one large central vacuole that maintains turgor and stores nutrients, while animal cells contain multiple smaller vacuoles. The plant central vacuole can occupy most of the cell's volume.
What is the primary role of peroxisomes in eukaryotic cells?
Photosynthesis
Protein synthesis
Energy production
Breakdown of fatty acids and detoxification
Peroxisomes contain enzymes that oxidize fatty acids and detoxify harmful compounds by producing and decomposing hydrogen peroxide. They play key roles in lipid metabolism and reactive oxygen species management.
Which protein filament in the cytoskeleton is primarily involved in muscle contraction?
Intermediate filaments
Collagen
Microtubules
Actin filaments
Actin filaments, also called microfilaments, interact with myosin to generate force in muscle contraction. They are flexible fibers composed of actin monomers and are crucial for cell motility and shape.
Which theory explains the origin of mitochondria and chloroplasts in eukaryotic cells?
Germ theory
Cell theory
Quantum theory
Endosymbiotic theory
The endosymbiotic theory proposes that mitochondria and chloroplasts originated from free-living bacteria engulfed by ancestral eukaryotic cells. Both organelles have their own DNA and double membranes. This theory is supported by genetic and structural evidence.
Which complex facilitates the transport of molecules between the nucleus and cytoplasm?
Endoplasmic reticulum
Ribosome
Golgi apparatus
Nuclear pore complex
Nuclear pore complexes are large protein assemblies embedded in the nuclear envelope that regulate bidirectional transport of RNA and proteins. They maintain the selectivity of nuclear-cytoplasmic exchange.
Why are mitochondria considered semi-autonomous organelles?
They have a double membrane
They are found in both plants and animals
They contain their own DNA and can replicate independently
They produce energy for the cell
Mitochondria possess their own circular DNA and ribosomes, enabling them to produce some of their own proteins and replicate independently of the cell cycle. This semi-autonomy supports the endosymbiotic theory. They still rely on nuclear genes for many functions.
Which cellular complex is responsible for targeted protein degradation in eukaryotic cells?
Ribosome
Lysosome
Peroxisome
Proteasome
The proteasome is a large protease complex that degrades ubiquitin-tagged proteins into peptides. This regulated proteolysis controls protein quality and cellular signaling. Dysfunction in proteasomes is linked to diseases like cancer and neurodegeneration.

Cheat Sheet

  1. Cell boundary structures: membrane vs. wall -

    When tackling a plant vs animal cell quiz, remember that all eukaryotic cells have a flexible phospholipid bilayer membrane, but plant cells also possess a rigid cellulose-rich cell wall that provides extra support. A handy mnemonic is "Walls of Cellulose, Membranes Flowus" to recall which structure is exclusive to plants. For more detail, see Campbell Biology or Khan Academy for validated definitions.

  2. Energy organelles: chloroplasts vs mitochondria -

    In the plant cell labeling game, distinguishing chloroplasts from mitochondria is crucial: chloroplasts convert light into chemical energy via photosynthesis, while mitochondria generate ATP through cellular respiration. A simple memory aid is "Photo → Chorus (plants), Mito → Might (universal powerhouse)." Explore peer-reviewed articles on NIH or Nature for deeper insights into the endosymbiotic origins of these organelles.

  3. Vacuole variations and turgor pressure -

    Plant cells feature a large central vacuole that maintains turgor pressure and stores metabolites, whereas animal cells contain multiple smaller vacuoles for transport and storage. Use the phrase "One giant vault in plants, many mini-hubs in animals" to solidify this distinction. University of California's cell biology resources detail vacuole functions and osmotic roles in living cells.

  4. Cytoskeleton components and roles -

    The dynamic cytoskeleton - comprising microtubules, actin microfilaments, and intermediate filaments - underpins cell shape, intracellular transport, and division in both plant and animal cells. In the plant and animal cell quiz, identify microtubules by their "25 nm hollow straw" appearance and filaments by their "7 nm rope" structure. Review microscopy data from the American Society for Cell Biology or NCBI imaging to master labeling.

  5. Nucleus and nucleolus: command center -

    The nucleus houses DNA and controls gene expression, while the nucleolus inside it assembles ribosomal RNA and proteins. A useful mnemonic is "NE controls; Nucleolus Excels in RNA cells" to remember functions during a quiz on animal and plant cells. For authoritative definitions, consult NCBI Bookshelf or the Genetics Society's educational guides.
