words only definitions & notes
  1. organelle
    a specialized part of a cell; analogous to an organ
    The interior of the cell is organized into many specialized compartments, or organelles, each surrounded by a separate membrane.
  2. cytosol
    the aqueous part of the cytoplasm within which various particles and organelles are suspended
    Between all these organelles is the space in the cytoplasm called the cytosol.
  3. Golgi apparatus
    a netlike structure in the cytoplasm of animal cells
    Organelles include mitochondria, which are responsible for the energy transactions necessary for cell survival; lysosomes, which digest unwanted materials within the cell; and the endoplasmic reticulum and the Golgi apparatus, which play important roles in the internal organization of the cell by synthesizing selected molecules and then processing, sorting, and directing them to their proper locations.
  4. mitochondrion
    part of a cell involved in energy production
    Organelles include mitochondria, which are responsible for the energy transactions necessary for cell survival; lysosomes, which digest unwanted materials within the cell; and the endoplasmic reticulum and the Golgi apparatus, which play important roles in the internal organization of the cell by synthesizing selected molecules and then processing, sorting, and directing them to their proper locations.
  5. cytoskeleton
    a microscopic network of actin filaments and microtubules in the cytoplasm of many living cells that gives the cell shape and coherence
    The cytosol contains an organized framework of fibrous molecules that constitute the cytoskeleton, which gives a cell its shape, enables organelles to move within the cell, and provides a mechanism by which the cell itself can move.
  6. lysosome
    a membrane-bound organelle containing digestive enzymes
    Organelles include mitochondria, which are responsible for the energy transactions necessary for cell survival; lysosomes, which digest unwanted materials within the cell; and the endoplasmic reticulum and the Golgi apparatus, which play important roles in the internal organization of the cell by synthesizing selected molecules and then processing, sorting, and directing them to their proper locations.
  7. plasma membrane
    a thin membrane enclosing the cytoplasm of a cell
    A cell is enclosed by a plasma membrane, which forms a selective barrier that allows nutrients to enter and waste products to leave.
  8. biosynthesis
    production of a chemical compound by a living organism
    The cytosol also contains more than 10,000 different kinds of molecules that are involved in cellular biosynthesis, the process of making large biological molecules from small ones.
  9. chloroplast
    organelle in which photosynthesis takes place
    In addition, plant cells contain chloroplasts, which are responsible for photosynthesis, whereby the energy of sunlight is used to convert molecules of carbon dioxide (CO2) and water (H2O) into carbohydrates.
  10. Golgi
    Italian histologist noted for work on the structure of the nervous system and for his discovery of Golgi bodies (1844-1926)
    Organelles include mitochondria, which are responsible for the energy transactions necessary for cell survival; lysosomes, which digest unwanted materials within the cell; and the endoplasmic reticulum and the Golgi apparatus, which play important roles in the internal organization of the cell by synthesizing selected molecules and then processing, sorting, and directing them to their proper locations.
  11. reticulum
    any fine network
    Organelles include mitochondria, which are responsible for the energy transactions necessary for cell survival; lysosomes, which digest unwanted materials within the cell; and the endoplasmic reticulum and the Golgi apparatus, which play important roles in the internal organization of the cell by synthesizing selected molecules and then processing, sorting, and directing them to their proper locations.
  12. plant cell
    a cell that is a structural and functional unit of a plant
    In addition, plant cells contain chloroplasts, which are responsible for photosynthesis, whereby the energy of sunlight is used to convert molecules of carbon dioxide (CO2) and water (H2O) into carbohydrates.
  13. cytoplasm
    the substance inside a cell, not including the nucleus
    Each cell contains only one nucleus, whereas other types of organelles are present in multiple copies in the cellular contents, or cytoplasm.
  14. molecule
    the simplest structural unit of an element or compound
    Organelles include mitochondria, which are responsible for the energy transactions necessary for cell survival; lysosomes, which digest unwanted materials within the cell; and the endoplasmic reticulum and the Golgi apparatus, which play important roles in the internal organization of the cell by synthesizing selected molecules and then processing, sorting, and directing them to their proper locations.
  15. photosynthesis
    formation of compounds in plants aided by radiant energy
    In addition, plant cells contain chloroplasts, which are responsible for photosynthesis, whereby the energy of sunlight is used to convert molecules of carbon dioxide (CO2) and water (H2O) into carbohydrates.
  16. synthesize
    combine and form a complex whole
    Organelles include mitochondria, which are responsible for the energy transactions necessary for cell survival; lysosomes, which digest unwanted materials within the cell; and the endoplasmic reticulum and the Golgi apparatus, which play important roles in the internal organization of the cell by synthesizing selected molecules and then processing, sorting, and directing them to their proper locations.
