Vocab I
Type of reproduction in which cells from two parents unite to form the first cell of a new organism.
What is sexual reproduction?
Cells do most of their growing during this phase:
What is G1?
During this phase, the chromosomes separate and move along spindle fibers to opposite ends of the cell.
What is anaphase?
Threadlike structure of DNA and protein that contains genetic information.
What is a chromosome?
This plant forms plantlets that grow into a new organism.
What is kalanchoe?
Process by which a cell divides into two new daughter cells.
What is cell division?
DNA is replicated during the S phase. The S stands for this:
What is synthesis?
This forms along the cell membrane just before cytokinesis in animal cells:
What is a cleavage furrow?
Phase of mitosis in which the duplicated chromosomes line up across the center of the cell.
What is metaphase?
This is the formula for calculating the volume of a cube.
What is Length x Width x Height?
Process of reproduction involving a single parent that results in offspring that are genetically identical to the parent
What is asexual reproduction?
Binary fission results in the production of two cells that are genetically this:
What is identical?
During this phase, a nuclear envelope re-forms around each cluster of chromosomes:
What is telophase?
This is the division of the cytoplasm to form two separate daughter cells.
What is cytokinesis?
As the size of a cell increases, the surface area to volume ratio does this:
What is it decreases?
Region of a chromosome where the two sister chromatids attach.
What is a centromere?
DNA and 8 histone molecules form beadlike structures called these:
What are nucleosomes?
From your book on page 485, this is generally the shortest phase of mitosis:
What is metaphase?
One of two identical “sister” parts of a duplicated chromosome.
What is a chromatid?
Hydras reproduce by this asexual process:
What is budding?
Structure in an animal cell that helps to organize cell division.
What is a centriole?
These are the 2 parts of the M phase:
What are mitosis and cytokinesis?
In your book on page 485, depending upon the type of cell, mitosis may last from this amount of time.
What is a few minutes to several days?
Series of events in which a cell grows, prepares for division, and divides to form two daughter cells.
What is the cell cycle?
These are 3 difficulties a cell faces as it increases in size:
What is: 1. it can't transport enough nutrients/oxygen in. 2. it can't transport all of the wastes out. 3. it places an information overload on the DNA?
