Verified By Experts /100% Success
Metaphase - Correct Answer -2nd stage of mitosis
Chromosomes aligned on equatorial plate of cell
Spindle fibers extend from centriole attach centromere of each chromosomes
Anaphase - Correct Answer -3rd stage of mitosis
Starts as spindle fibers move sister chromatids apart towards poles
Each chromatid now a chromosome of one DNA double helix with its own
centromere
Telophase - Correct Answer -Arrival of group of chromosomes at each pole
Begin to uncoil and return to chromatin
New nucleolus formed in each cell
Mitotic spindle broken up
New envelope forms around chromosomes
End nuclear division
,Spindle-fibers (apparatus) - Correct Answer -a football-shaped, cagelike structure
consisting on thin fibers made up of microtubules
Metaphase Plate - Correct Answer -Plane midway between the two pole of the
cell where chromosomes line up during metaphase
daughter chromosomes - Correct Answer -during mitosis, the seperated
chromatids from the beginning of anaphase onward
Cleavage Furrow - Correct Answer -two new daughter cells
Series of mitotic cell divisions occuring in the zygote immediantly following it
fertilization
Nuclear Membrane - Correct Answer -The nucleus is enclosed within a double
membrane that is called nuclear envelope/.......
It seperates the cytoplasm from the nucleoplasm (the fluid within the nucleus)
Sister Chromatids - Correct Answer -replicated DNA of the chromsome with both
copies joined together at the centromere
, Mitosis - Correct Answer -cell division that occurs in SOMATIC CELLS (all cells other
than sex cells)
Meiosis - Correct Answer -Cell division in SEX CELLS (cells that give rise to sperm
or oocytes)
Somatic Cell Division - Correct Answer -One cell divides to produce two cells
necessary for development, tissue growth, replacement of old cells, tissue repair
Diffusion - Correct Answer -Net movement of a substance from area of GREATER
concentration to an area of LESSER concentration
Molecules and ions in constant motion due to Kinetic Energy
if unstopped, ......... continues until substance reaches equilibrium (molecules
distributed evenly throughout given area)
Simple Diffusion - Correct Answer -molecules pass between phospholipid
molecules
small and nonpolar solutes
INCLUDE: Respiratory gases (O2 and CO2), some fatty acids, ethonal, urea
NOT regulated by plasma membrane
