- Organism
Identify the planes of the body
- Sagittal Plane: divides the body into left and right parts
- Frontal Plane: divides the body into anterior and posterior parts
- Transverse Plane: divides the body into superior (upper) and inferior (lower) parts
Best way to adjust light in Microscope
use the Iris Diaphragm
Relationship between the magnification of the objective and the light intensity and field of view and the working distance
Light intensity decreases as i goes from low power to high power
What term is used to describe the movement of dye through a plate of solid agar
Diffusion
Carpus
Wrist
Function of the cell membrane
selectively permeable barrier
Function of Cytoplasm
fluid part of cell that supports and moves substances in the cell
Function of Ribosomes
protein synthesis
Preliminary Focusing should be what power
Low
How do Objects appear under microscope
Upside down and reversed
The solutes outside the cell exceed whats inside the cell is called
Hypertonic
The solutes outside the cell are equal to whats inside the cell is called
Isotonic
The solutes outside the cell are less than whats inside the cell is called
Hypotonic
Which transport processes require carrier proteins
active transport and facilitated diffusion
Directional terms to describe location of body parts (pg4)
Eg. Lungs are lateral to the Heart
Hand is Distal to the Torso
What effect does the loss of the nucleus have on the mature RBC
Can not divide, make proteins, or carry out Mitosis
What is an Organelle
Specialized cellular compartments that carry out a variety of functions
Label a Drawing of a duplicated chromosome
- Chromatide
- Centromere
- Chromosome
What is Diffusion
going form an area of greater concentration to an area of lower concentration
Passive transport across a membrane
What is Osmotic Pressure
the force necessary to stop the slow of water across a membrane
What is Active Transport
Movement across a membrane that requires energy (ATP)
What is Facilitated Diffusion
Carrier proteins transport molecules across a membrane that are too large to fit though by themselves. DOES NOT require energy
What is Vesicular Transport
Transport into or out of a cell through the vesicles .
Requires Energy
What is the Function of Peroxisomes
metabolize fatty acids, detox cellular chemicals
What is the Function of Mitochondria
Produces Energy
What is the Function of Rough Endoplasmic Reticulum (RER)
Location of Ribosomes
What is the function of Golgi Apparatus
Packing area
What is the function of Lysosomes
digest particles brought into cell
What is the function of Centrioles
make the microtubules
What is the function of a Nucleus
Control Center
Phases of Mitosis match the stage (pg46)
- Meta phase
- Ana phase
- Telo phase
- Inter phase
- Pro phase
What is Osmosis
Diffusion of water across a cell membrane
