The rate at which materials enter and leave the cell depends on the cell's ______________.
surface area.
100
Genetic information is bundled into packages of DNA known as _________________.
chromosomes
100
What is the main event during Cytokinesis?
The division of the cytoplasm itself.
100

The cell cycle is composed of these general processes.

Growth and Division.

100
Sister chromatids are attached to each other at an area called the ____________.
The Centromere
200

Mitosis is a form of _____________________ reproduction.

Asexual

200
What is the shortest phase of Mitosis?
Metaphase
200
True or False: Cytokinesis is the process that takes the longest during the Cell Cycle. (If the answer is false, what is the correct answer?)
False; Interphase.
200

The chromosomes in eukaryotic cells form a close association with histones, a type of protein. These coil up to form ___________.

chromatid or chromosome

200
What phase of the cell cycle lasts the longest?
Interphase
300
In order for a cell to divide successfully, the cell must first _______________.
duplicate its genetic information
300
What are the four phases of mitosis in order?
Prophase, Metaphase, Anaphase, Telophase
300

Cytokinesis usually occurs at the same time as or right after _________.

Telophase

300
A protein called _________ regulates the cell cycle.
cyclin
300
In eukaryotes, cell division occurs in two main stages. The first state of the process, division of the cell nucleus, is called _________________.
mitosis
400

Cell division solves the problem of ____________ and the problem of _______________.

information crisis/overload; increasing size by reducing cell volume

400

True or False (correct the statement if false): During mitosis in an animal cell during prophase, the chromosomes line up at the middle of the cell, connected to spindle fibers.

False: the step described is metaphase.

In prophase, DNA condenses & forms chromosomes. The nuclear envelope breaks down. The spindles start to form.

400

In most animal cells, the cell membrane is drawn inward until the ____________ is pinched into two nearly equal parts. Each part contains its own ____________ and __________.

cytoplasm; nucleus and organelles.

400

In general, what are the three steps that happen during the cell cycle?

A cell grows, prepares for division, and divides into two daughter cells.

400
The phase in which the chromosomes lineup at the center of the cell is called ___________.
Metaphase
500

Why does a cell have to eventually stop growing and split?

- Trouble getting oxygen & nutrients in

- Trouble getting waste products out

500
Draw and name the phase in which the chromosomes separate and move along spindle fibers to opposite ends of the cell in a Eukaryotic cell.

500

In plant cells, the cell membrane is not flexible enough to draw inward because of the rigid cell wall that surrounds it. Instead a structure, _________, forms halfway between the divided nuclei. It gradually develops into _______, that separate the two daughter cells.

cell plate; cell membrane

500
The process of cell division in prokaryotes is a form of asexual reproduction known as _______________.
binary fission
500
____________ are caused by the defects in the genes that regular cell growth and division.
Cancer
