Lab Introduction Flashcards
Coarse adjustment knob
The large adjustment knob for use on scanning magnification to bring slide into focus, located on each side of the microscope
Fine adjustment knob
The smaller knob adjacent to coarse adjustment knob is used to focus on the slide on the intermediate and high magnifications
Slide stage & clip
Where to place the slide to view through the binocular eyepieces, the clip holds the slide into place
Stage X and Y knobs
These knobs move the slide stage along the X and Y axis, move to view different parts of the slide
Reproductive structures in angiosperms
flowers
Reproductive structures in gymnosperms
cones
Types of tissue systems in plants
Vascular, dermal, ground
Dermal tissue components & function
Components are epidermis and periderm. Functions include protection and prevention of water loss
Ground tissue components & function
Components are parenchyma, collenchyma, and sclerenchyma. Functions include photosynthesis, food storage, regeneration, support and protection
Vascular tissue components & function
Components are xylem and phloem. Functions include transport of water and minerals, transport of food
This indicates that the tissue observed on the slide came from a median cut along the length of the stem (l.s)
Longitudinal section
This indicates that the tissue observed on the slide came from a cross cut of the stem (c.s)
Cross section
This indicates that a whole structure or organism was placed on the slide (w.m.)
Whole mount
What is included on the slide description
Type of plant, section of plant, and location on the plant
Which cells are the most numerous type of cells in plants
Parenchyma
Parenchyma cells
Thin-walled, living cells that are found in many tissues within a plant.
Commonly used to stain starch within parenchyma cells
Iodine
Collenchyma cells
Provide flexible support to young stems as well as leaves. Unevenly thickened cell walls and are elongated
Epidermis
The thin outer covering for a plant that is usually a single cell layer thick
Collenchyma cells may form
A cylinder beneath the epidermis or as vertical strands forming “ribs” for support
