Physiology Chapter 3 Flashcards
Semi fluid portion of the cytoplasm
Cytosol
Protein synthesis occurs here
Ribosomes
Control center
Nucleus
Intracellular structures with specific functions
Organelles
Responsible for forming spindle during mitosis
Centrosome —- 90°
Modifies, sorts, packages and delivers proteins and lipids
Golgi complex
Organelles that destroy bacteria and recycle worn put cell parts
Lysosomes —- small parts
Non-membranous chemical substances that are produced and used by cells
Inclusions
Located inside the nucleus and helps assemble ribosomes
Nucleolus
Cellular respiration occurs here
Mitochondria
Passive transport depends on ______ energy to move materials
Kinetic
When a solution reaches equilibrium, an ______ number of molecules improve in and out of the cell.
Equal
Mechanisms that move substances across a cell mebrane requiring energy are known as
Active transport
__________ Is the infolding of a cells membrane around liquid droplet to bring it into the cell
Pinocytosis
In passive transport p net movement if substances is (up, down) their concentration gradient.
Down
Movement of any substances from a high concentration to a low concentration whether or not a membrane is involved is called
Simple diffusion
Movement of a substance from a low concentration to high concentration is
Active transport
In exocytosis, these structures unite with the cell membrane and release their contents to the outside of the cell
Vesicles
Phagocytosis is the process by which __________ are taken through a cell membrane
Insolvable solids/large particles
Gradient means
Difference
The majority of the plasma membrane is composed of
Phospholipids
Cellular contents located between the plasma membrane and the nuclear membrane are called the
Cytoplasm
The two types of ER are _______ and _______
Smooth and rough
The ________ are attached to the rough ER
Ribosomes
The _______ is the largest cell structure that contains both DNA and the nucleolus
Nucleus
Examples of inclusions are
Melanin, fat, glycogen
______ is composed of 75-90% water
Cytosol
Raises or lowers condenser
Condenser adjustment knob
Secures a slide for viewing
Slide holder
Lens, located beneath the stage opening which controls the light beam size
Condenser
Used for preliminary focusing
Coarse adjustment knob
Platform in which slides are placed
Stage
Used for final focusing
Fine adjustment knob
The part of the microscope used when we carry it
Arm
Controls the intensity of the light
Iris
Term that is given to a microscopes ability to distinguish and separate fine detail
Resolving power
The objective that comes closest to a specimen and is most likely to break a slide
Oil immersion – 100x
To find the total magnification you
Multiply the ocular by the objective
When you are viewing an object under low power do you see more so less of the object as compared to high power?
More
What property of the microscope allows you to change from one objective to another without having to make major focusing adjustments?
Parfocal
Red blood cells may swell and rupture if placed in a ________ solution
Hypotonic
Hypertonic means that a solution has more ______ as compared to another solution
Solute
The movement of a substance from high to low concentration through the plasma membrane with the help of a channel protein is known as
Facilitated diffusion
