This happens before Mitosis begins, sometimes called the "chill" phase. The DNA duplicates as it prepares for division.
What is interphase?

Living organisms can be classified as prokaryotes or eukaryotes. These two structures are common to both prokaryotic and eukaryotic cells:
a) cell wall and nucleus
b) cell wall and chloroplast
c) plasma membrane and nucleus
d) plasma membrane and cytoplasm

In this first stage of mitosis, the chromosomes "pair up."
What is prophase?
200
This occurs during prophase I to allow for genetic variation among cells.
What is crossing over?
200
This phase of Meiosis is exactly the same as Mitosis: phase I or phase II.
What is phase I?
200
A cell with more dissolved substances inside than out will ______________in a hypotonic solution. (i.e. egg in blue water)
What is swell?

Using a microscope, a student observes a small, green organelle in a plant cell. This energy transformation most likely occurs first within the observed organelle:
a) ATP to light
b) light to chemical
c) heat to electrical
d) chemical to chemical
What is light to chemical?
300
In the third stage of mitosis, the chromosomes are pulled "apart" toward the poles of the cell.
What is anaphase?
300
This is the phase of meiosis I and II where the chromosomes begin to pull apart.
What is anaphase?
300
This is the name for the 4 cells which are formed at the end of Meiosis II: diploid or haploid.
&
The number of chromosomes that each cell has at this point.
What is haploid? and half?
300
A cell with more dissolved substances outside than in will ______________in a hypertonic solution. (i.e. egg in molasses)
What is shrink?

The rough ER and Golgi Apparatus work together in eukaryotic cells. This is one way that the rough ER assists the Golgi Apparatus:
a) it assembles nucleic acids from monomers
b) it breaks down old, damaged macromolecules
c) it packages new protein molecules into vesicles
d) it determines which protein molecules to synthesize
What is it packages new protein molecules into vesicles?
400
In this second stage of mitosis, the chromosomes line up in the middle along the equator.
What is metaphase?
400
The haploid cells that are created during meiosis, (are or are not) identical to the parent.
What is are not?

A researcher observing an ecosystem describes teh amount of sunlight, precipitation, and type of soil present. This is the factor the researcher most likely describing:
a) biotic factors in a forest
b) biotic factors in a tundra
c) abiotic factors in a prairie
d) abiotic factors in an ocean
What is abiotic factors in a prairie?

In this final stage of mitosis, the cells have completely split and two identical copies have been made.
What is cytokinesis?
500
Identify and describe the phases of meiosis I in order.
What is prophase I (pair up), metaphase I (meet in middle), anaphase I (pull apart), telophase (chromosomes become chromatin and two cells are created, preparing for Meiosis II)?
