Human Biology Quiz 3

Sep 23 2007

OrganellesAnswer
What does ER synthesize involved in synthesis of protein
Rhibosomes whithin ER produce primary structures which ER modifies later
ER does what with cellular substances synthesizes, modifies, transport
what has no ribosomes and is used for trasnportation smooth ER
what sort of ER is most often found in secretion cells such as the throat smooth ER
In Rough ER, rhibosomes are adhered to one side
Stacks of membranous, flattened sacs Golgi bodies
charactersitics of the Golgi body dynamic, always forming and diminishing, they continue the chemical functions of the ER
vescicles are membrane bound vacuules
Lysosomes contain digestive enzymes that are synthesizied by Golgi bodies
prokaryotic characteristics simple, single cell forms of life, biochemically complex
what is an example of a prokaryotic organism blue green algae (Monera)
prokaryotic bacteria have many structures on the inside, many ribosomes, DNA
EUKARYOTIC TRUE NUCLEAS
EUKARYOTIC HAVE NUMEROUS MEMBRANE SURROUNDED ORGANELLES,
EXAMPLES OF EUKARYOTIC ORGS: PROTISTA, PLANTAE, ANIMALIEA
SIMILIAR CELLS COMBINE TO FORM TISSUES, ORGANS. SYSTEMS, ORGANISMS
7 Fx of a cell synthesis, assimilation, digestion, transportation, energy transformation, responses, movement (SAD TERM)
two types of transport passive and active
cells are organized, living, membranous, have a variety structures
cell theory all organisms have at least 1 cell, cell = basic unit of life, and all cells come from pre existing cells
plant cell vs animal plants have cell wall & membrane, animal just membrane
plant chemicals vs animal chemicals in a cell plant cytoplast chloroplast animals = sentioles
cilia hairs for movement
flagella whip like chord for movement
plasma membrane organelle does : seperates internal/external; selectively permeable,
plasma membrane is made of proteins and phospholipids, make a bi lipid layer
microtrabecular lattice skeleton of cell
microtrabecular lattice is a maze like network of hollow fibers that connects and supends organelles
cyto skeleton is also called microtrabecular lattice, or cytoplasmic matrix

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.
