  • Resolution is the ability to distinguish two separate points or objects.

  • The compound microscope was invented by Anton van Leeuwenhoek.

  • The smallest unit of life is the cell.

Page 2:

  • The compound microscope uses light to magnify objects.

  • It can magnify objects 400 to 1000 times.

Page 3:

  • The transmission electron microscope was first invented in 1932.

  • It uses a beam of electrons to magnify the specimen.

  • It can magnify up to 600,000 times.

Page 4:

  • The scanning electron microscope passes a beam of electrons over the specimen.

  • It projects a 3D image onto a computer.

Page 6:

  • Atoms are groups of protons, electrons, and neutrons.

  • Molecules are groups of atoms.

  • The nucleus controls the daily activities of the cell.

Page 24:

  • Inside the nucleus, there is a nucleolus.

  • The nucleolus produces RNA and ribosomes.

Page 25:

  • Inside the nucleus, DNA is organized into multiple, linear chromosomes.

  • Chromatin represents the mass of stringy, entangled chromosomes observed during interphase.

Page 26:

  • A diagram shows a human chromosome.

Page 27:

  • The nucleoplasm is a jelly-like fluid that supports the contents of the nucleus.

Page 28:

  • The cytoplasm is a gel-like substance inside the cell.

  • It dissolves nutrients throughout the cell and suspends organelles.

Page 29:

  • The mitochondrion is an organelle within all cells.

  • It looks like a long worm inside a sandwich bag.

  • It is the powerhouse of the cell and produces ATP.

Page 30:

  • Vacuoles are hollow organelles used for storage within the cell.

  • Plant cells contain a large central vacuole.

Page 31:

  • A diagram shows a eukaryotic plant cell and a eukaryotic animal cell.

Page 32:

  • Ribosomes are small organelles responsible for protein synthesis.

Page 33:

  • The endoplasmic reticulum is a long system of tubes and canals throughout the cell.

  • It provides for intracellular transport of molecules.

  • There are two types of endoplasmic reticulum: rough ER and smooth ER.

Page 34:

  • A diagram shows the structure of the endoplasmic reticulum.

Page 35:

  • Both rough ER and smooth ER are present in the cell.

Page 36:

  • The Golgi complex looks like a stack of pancakes.

  • It packages materials for export and facilitates intercellular transport.

Page 37:

  • Lysosomes are spherical bodies that contain enzymes for intracellular digestion.
