Bio Cells Test

mitosis, cell cycle, label cell diagram

TermDefinition
main characteristics of a prokaryotic cell no nucleus simple make up unicellular not membrane bound no specialized functions
main characteristics of a eukaryotic cell nucleus complex make up multicellular membrane bound specialized functions
main characteristics of a bacterial cell flagella no organelles simple make up prokaryotic
main characteristics of a plant cell chloroplast organelles membrane bound cell wall eukaryotic complex make up
main characteristics of an animal cell no cell wall membrane bound organelles eukaryotic complex make up
nucleus controls all cell function, contains hereditary information for the cell (ie DNA and chromosomes)
cell membrane outer "skin" of the cell, controls passage in and out of the cell
cell wall surrounds the cell membrane, provides strength and protection for the cell
chloroplast organelle in which photosynthesis occurs, contains chlorophyll to absorb light energy, found only in plant cells
mitochondria organelles that use nutrients in the cell to produce energy for the cell
vacuole bubble-like structures that store food, water, and other materials withing the cell
endoplasmic reticulum a series of channels and canals that can transport substances within the cell
golgi body stores and packages chemicals within the cell and transports chemicals to the surface of the cell
ribosomes organelle that makes proteins for the cell
lysosomes organelle that digests materials in the cell
cytoplasm consists of fluid and organelles in which most most functions occur, includes each part of the cell
centrioles organizing microtubules that serve as the cell's skeletal system, help determine the locations of the nucleus and other organelles within the cell
first part of cell theory all living things are composed of cells
second part of cell theory cells are the basic unit of structure and function of living things
third part of cell theory all cells come from pre-existing cells
how do u make a wet mount slide 1-2 drops of water specimen, put on the cover slip
interphase not accompanied by visible changes under the microscope, and includes the G1, S and G2 phases. During interphase, the cell grows, replicates its DNA, and prepares for mitosis
prophase chromatin condenses into chromosome, nucleolus disappears, nuclear envelope disintegrates
metaphase chromosomes are attached to kinetochore spindle fibers, chromosomes align in the center of the cell on the metaphase plate
anaphase sister chromatids separate at the centromere, chromosomes are pulled to opposite poles of the cell by spindle fibers
telophase spindle fibers disappear, new nuclear envelopes form, chromosomes diffuse into chromatin again
cytokinesis cytoplasm divides, a cleavage furrow develops, indentation of the cell membrane between the daughter nuclei, contractile ring closes the new cells
what is the purpose of mitosis to produce two new daughter cells from one mother cell that have identical chromosomes
what is cancer some of the body's cells grow uncontrollably and spread to other parts of the body
how many chromosomes do humans have 46
how many chromatids do humans have 92
what is a chromosome a long DNA molecule with part or all of the genetic material of an organism
when do chromosomes replicate during interphase
what is the centromere links a pair of sister chromatids together during cell division

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.

To see how well you know the information, try the Quiz or Test activity.
