    What defines a eukaryotic cell?

    Contains a nucleus and membrane-bound organelles.

    What is the function of mitochondria?

    Responsible for cellular respiration and ATP production.

    How do prokaryotic cells differ from eukaryotic cells?

    Prokaryotes lack a nucleus and membrane-bound organelles.

    What is the role of the cell membrane?

    Acts as a selective barrier regulating substance entry and exit.

    What happens during interphase?

    Cell grows and prepares for division, synthesizing proteins.

    What is chromatin?

    DNA in a relaxed state, not yet condensed into chromosomes.

    What is the structure of the nuclear envelope?

    Composed of two membranes with nuclear pores for transport.

    What distinguishes protozoa from metazoans?

    Protozoa are unicellular, while metazoans are multicellular.

    What is the significance of ribosomes in prokaryotes?

    They are sites for protein synthesis, similar to eukaryotic ribosomes.

    What is the function of the Golgi apparatus?

    Modifies, sorts, and packages proteins for secretion.

    What is the role of chloroplasts in plant cells?

    Conduct photosynthesis by converting light energy into chemical energy.

    What is the difference between endocytosis and exocytosis?

    Endocytosis brings substances into the cell; exocytosis expels them.

    What is a nucleoid?

    Region in prokaryotes containing circular DNA, not enclosed by a membrane.

    What is the primary function of lysosomes?

    Digestive organelles that break down waste materials and cellular debris.

    What is the composition of the cell wall in plants?

    Made of cellulose, providing structure and support.

    What happens if a eukaryotic cell lacks mitochondria?

    It would rely on anaerobic processes for energy production.

    What is the role of the cytoskeleton?

    Provides structural support and facilitates intracellular transport.

    What defines a prokaryotic cell?

    Simpler structure without a nucleus or membrane-bound organelles.

    What is the function of vacuoles in plant cells?

    Store nutrients, waste products, and help maintain turgor pressure.

    How do eukaryotic cells reproduce?

    Through mitosis, ensuring genetic material is evenly distributed.

    What is the significance of histones in eukaryotic cells?

    They help package and condense DNA into chromosomes.

    What defines a eukaryotic cell?

    Contains a nucleus and membrane-bound organelles.

    What is the function of mitochondria?

    Responsible for cellular respiration and ATP production.

    How do prokaryotic cells differ from eukaryotic cells?

    Prokaryotes lack a nucleus and membrane-bound organelles.

    What happens during interphase?

    Cell grows and prepares for mitosis.

    What is the role of the cell membrane?

    Acts as a selective barrier for substances entering and exiting the cell.

    What characterizes prokaryotic DNA?

    It is circular and not enclosed in a nucleus.

    What is the structure of the eukaryotic nucleus?

    Surrounded by a double membrane with pores for substance transport.

    What is the primary function of ribosomes?

    Synthesize proteins from amino acids.

    What distinguishes plant cells from animal cells?

    Plant cells have a cell wall, chloroplasts, and large vacuoles.

    What is endocytosis?

    Process of engulfing substances into the cell via membrane invagination.

    What is the significance of chromatin?

    Contains DNA and proteins, condensing to form chromosomes during cell division.

    What are lysosomes responsible for?

    Digesting cellular waste and foreign materials.

    What is the cytoskeleton's role?

    Provides structure and facilitates intracellular transport.

    What is the difference between rough and smooth endoplasmic reticulum?

    Rough ER has ribosomes; smooth ER is involved in lipid synthesis.

    What is the function of chloroplasts?

    Conduct photosynthesis by converting light energy into chemical energy.

    What is the role of the Golgi apparatus?

    Modifies, sorts, and packages proteins and lipids for secretion.

    What happens during mitosis?

    Cell divides its nucleus and genetic material into two daughter cells.

    What is the primary component of the cell wall in plants?

    Cellulose provides structure and support.

    What is phagocytosis?

    A type of endocytosis for engulfing large particles or cells.

    What is the significance of the nucleolus?

    Site of ribosomal RNA synthesis and ribosome assembly.

    What is the difference between eubacteria and archaebacteria?

    Eubacteria have peptidoglycan in their cell walls; archaebacteria do not.
