  • Matthias Schleiden contributed to the cell theory by concluding that
    all plant parts were made of cells
  • prokaryotes that include such types as heat-loving, salt-loving, and methane-making
    archaea
  • an organelle that contains the cell's DNA
    nucleus
  • Robert Hooke and Anton van Leeuwenhoek not only helped discover cells but also
    helped develop the mircroscope
  • What part of the cell forms a barrier between the cell and its environment?
    cell membrane
  • What part of the cell keeps the cell membrane from collapsing?
    cytoskeleton
  • word that describes most organisms that you can see with your naked eye **hint more than one cell
    muticellular
  • What is the smallest unit that can perform all the processes necessary for life
    cell
  • Leeuwenhoek called the single-celled organisms "animalcules" Today we call them
    protists
  • What cell parts carry materials between organelles such as the ER and the Golgi complex?
    vesicles
  • The part of the cell that keeps the cytoplasm inside and controls what goes in and out of the cell
    cell membrane
  • a single-celled organism that has no nucleus or membrane-bound organelles
    prokaryote
  • Energy released by a cell's mitochondrion is stored in
    ATP
  • the smallest and most common form of prokaryotes, containing DNA, ribosomes, and a flagelllum
    bacteria
  • What cell part is only found in a plant cell
    cell wall
  • organisms made up of cells that have a nucleus and membrane-bound organelles
    eukaryotes
  • Ribosomes, the organelles that make proteins, are found on the membranes of the
    endoplasmic reticulum
  • The function of a part of an organism is related to its
    structure
  • A cell's nucleus contains DNA which carries genetic material with instructions on how to make
    protein
  • structures that are usually surrounded by membranes and which perform specific functions within the cell
    organelles
