    Botany or Plant Biology comes from Greek word?
  • botanique (botanical)

    Botany or Plant Biology comes from French word?
  • - multi cellular, eukaryotic living thing
    - belong in kingdom plantae
    - can make their own food
    - has roots, stem, and leaves

    Plants can be defined in many ways
  • Autotrophs
    Can make their own food
  • Ground tissue
    Most of the interior of a plant.
  • Parenchyma, Collenchyma and sclerenchyma cells
    Types of ground tissue
  • Parenchyma cells
    are found throughout the plant but are the only site of photosynthesis since they contain chloroplasts and palisade mesophyll.
  • Collenchyma and sclerenchyma cells
    provide plants with structural support.

    The scientific method
  • small + to examine
    mikros "___" + skopein "___"
  • microscope
    is an instrument designed to produce a magnified visual or photographic image of objects or organism that are too small to be seen by the naked eye.
  • Light Microscopes
    are one of the most important tools in research and biology. Basically, it employs the principles of refracting and reflecting visible light to detect tiny objects.
  • Dissecting Microscopes
    permit the viewing of opaque objects up to 30x its original size.
  • Eyepiece or Lens or Oculars
    - used to view, magnify and produce images of opaque objects
  • Vertical Limb
    - movable rods that holds the eyepiece
  • Stage Clips
    - used to hold the specimen in place on the stage
  • Stage
    - rectangular glass plate where the specimen is placed for observation
  • Adjustment Knob/Screw
    - used to adjust the vertical limb up and down
  • Mirror
    - reflects light rays to the stage where the specimen is observed
  • Stand
    - attached to the foot or the base to provide support to other parts Foot or
  • Base
    - basal part which holds the weight of the whole weight of the microscope
  • Compound Microscope utilize a two
    -lens system (eye piece and objectives), a controllable illumination system, and a geared-focusing mechanism. Materials examined in this type of microscope required to be thinly slice for light to pass through and magnify the specimen up to 1500x its original size.
  • Base
    - V or U shaped which supports the whole microscope
  • Arm
    - connects the base to the body tube; serves as a handle when carrying the microscope
  • Stage
    - platform that holds the slide; has an opening in the center which allows light to pass from the illuminating parts
  • Pillar
    - area where the arm is attached
  • Stage Clips
    - holds the slide containing the specimen firmly on the stage
  • Substage
    - area below the stage which holds the condenser above and the diaphragm below
  • Body Tube
    - cylinder that attached the draw tube to the microscope; acts as the passage of light from obiective to the eyepiece
  • Course Adjustment Knob
    - upper, larger knobs for the slow movement of the body tube when focusing under the low power objective (LPO)
  • Fine Adiustment Knob
    - for the slow movement of the body when focusing under the high-power objective (HPO) and other high power lenses
  • Revolving Nose Piece
    - carries the objectives; can be turned to select the appropriate obiective lenses
  • Draw Tube
    - smaller cylinder attached to the upper part of the body tube that holds the ocular
  • Mirror
    - planar on one side and concave on the other
    - used to reflect light and lenses of the eye concave side of the mirror is used for the natural light while the
    - flat side is used for artificial light held by a mirror rack
  • Condenser
    - located on a substage held in place by a rack used to condense or concentrate the light reflected from the mirror to the object or specimen being examined
  • Diaphragm
    - situated above the condenser which controls the amount of light that reaches the specimen
  • Eyepiece/Ocular
    - detachable cylinder located at the upper end of the tube which may have line inside that serves as a pointer and rotates as the ocular is rotated
  • Objectives
    - has two or three obiectives attached to the revolving nosepiece
  • Scanner
    - shortest cylinder with the largest opening has large lens for very low magnification used to observe much wider field of the object; marked with
  • "4x" Low Power Objective (LPO)

    - shorter cylinder with a larger lens opening used to observe the general outline and locate various parts of a specimen focused using the course adjustment; 10x magnification
