Cristae are folds of the inner mitochondrial membrane that increase its surface area. This expanded area houses proteins of the electron transport chain and ATP synthase. The high surface area supports efficient ATP production. .
What is the primary function of the nucleolus?
DNA replication
Synthesis of ribosomal RNA and assembly of ribosomal subunits
Protein folding
Lipid synthesis
The nucleolus is a dense region within the nucleus where rRNA genes are transcribed and ribosomal subunits are assembled. It organizes the processing and packaging of rRNA with proteins. Ribosomal subunits then exit to the cytoplasm for final assembly. .
The rough endoplasmic reticulum is continuous with which cellular structure?
Golgi apparatus
Outer nuclear membrane
Inner nuclear membrane
Plasma membrane
The membrane of the rough ER is continuous with the outer nuclear membrane, allowing direct transport of proteins and lipids between these compartments. This continuity is crucial for integrated nuclear and ER functions. .
Which process describes the fusion of vesicles with the plasma membrane to release their contents outside the cell?
Phagocytosis
Exocytosis
Transcytosis
Endocytosis
Exocytosis is the process where cellular vesicles fuse with the plasma membrane, releasing their cargo into the extracellular space. This mechanism is critical for secretion of hormones, neurotransmitters, and waste removal. .
Intermediate filaments are primarily responsible for which cellular property?
Muscle contraction
DNA replication
Vesicle transport
Mechanical strength and stability
Intermediate filaments form a rope-like network that provides tensile strength and mechanical support to cells. They stabilize cell shape and anchor organelles. Unlike microtubules and microfilaments, they resist stretch. .
Which organelle is central to the endomembrane system in eukaryotic cells?
Golgi apparatus
Mitochondrion
Nucleus
Endoplasmic reticulum
The endoplasmic reticulum (ER) is the largest membrane-bound organelle and serves as the entry point of the endomembrane system. It synthesizes lipids, proteins, and assists in calcium storage. Other components like the Golgi, lysosomes, and vesicles are functionally connected to the ER. .
Which cellular structure regulates the entry and exit of molecules from the nucleus?
Chromatin

Cheat Sheet

  1. Cell Membrane - The Selective Barrier -

    The phospholipid bilayer controls the passage of ions and molecules, acting like a security gate (Alberts et al., Molecular Biology of the Cell). When you practice labeling animal cell diagrams in our cell labeling quiz, look for its thin, flexible outline to distinguish it from plant cell walls. Remember the mnemonic "FLIP-FLOP" for the fluid and flexible phospholipids.

  2. Nucleus - The Control Center -

    The nucleus houses DNA and directs cellular activities, making it the most prominent organelle (Campbell Biology, 11th Edition). In your animal cell labeling game, spot the dark-stained sphere at the center and label the nuclear envelope, nucleolus, and chromatin. Try the phrase "NEC" (Nucleolus, Envelope, Chromatin) to remember its major parts.

  3. Mitochondria - The Powerhouse -

    Mitochondria generate ATP through cellular respiration, supplying energy for the cell (National Institutes of Health). In a label parts of a cell quiz, look for the bean-shaped organelle with inner folds called cristae. Use the rhyme "Mighty Mite Makes Energy Right" to recall its powerhouse role.

  4. Endoplasmic Reticulum - Rough vs. Smooth -

    The rough ER is studded with ribosomes for protein synthesis, while the smooth ER handles lipid production and detoxification (Khan Academy). When labeling an animal cell diagram, identify the rough ER by its dotted texture and the smooth ER by its tubular network. Think "R-ER for Ribosomes, S-ER for Soaps" to keep their functions straight.

  5. Golgi Apparatus & Lysosomes - Packaging and Recycling -

    The Golgi apparatus modifies, sorts, and ships proteins, while lysosomes contain enzymes for waste breakdown (University of California, Berkeley). In a cell labeling quiz, the Golgi looks like a stack of flattened pancakes, and lysosomes are small round vesicles. Remember "Golf Bags & Little Bins" to map Golgi and Lysosomes correctly.
