Chapter 10 quiz
Each cell has genetic coded information and a specific number of chromosomes for every organism. There are ___ chromosomes in human cells. Chromosomes are only visible during ________________.
46, cell division
The production of genetically identical offspring fro, a single parent is known as _____________
Asexual reproduction
______________ is reproduction that involves a single parent producing an offspring. The offspring produced are, in most cases, genetically __________ to the single cell that produced them.
Asexual reproduction, identical
binary fission is a form of ____________ reproduction during which two genetically ____________ cells are produced
Asexual, identical
For example, bacteria reproduce by
Binary fission
What is the role of chromosomes in cell division?
Chromosomes make it possible to separate DNA precisely during cell division.
The ratio of surface area to volume is key to understanding why cells must _______________ as they grow
Divide
A larger cell is less efficient in ___________________ and ____________ across its cell membrane.
Moving nutrients and waste materials
Asexual reproduction has
No genetic diversity
Prokaryotic cells lack ___________.Instead their DNA Molecules are found in the __________
Nuclei, cytoplasm
In eukaryotic cells, chromosomes are located in the ______, and are made up of __________
Nucleus, chromatin
Sexual reproduction
Produces genetically diverse offspring, genetic diversity helps ensure survival of species when environment changes.
Asexual reproduction
Produces genetically identical offspring, reproduction is quick amd produces large number of offspring
Offspring produced by _________________________ inherits some of their genetic information from each parent
Sexual reproduction
In ______________, offspring are produced by the fusion of ___ sex cells- one from each of two parents. These fuse into a single cell before the offspring can grow.
Sexual reproduction, 2
At the start of cell division, they condense close together forming visible structures. When visibility begins each chromosome will consist of "2" identical ________________. Each pair is attached to an area called _______________, located near the middle
Sister chromatids, centromere
Which statement is true regarding a cells surface area to volume ratio
Smaller cells will have a greater surface area to volume ratio
The rate at which this exchange takes place depends on the __________________ of the cell
Surface area
Bacteria and amebas reproduce by
binary fission
When DNA replication is complete, the cells divide through a process known as
binary fission
Yeast and Hydra's reproduce by
budding
Before a cell grows too large, it divides into two new "daughter" cells in a process called
cell division
Food, oxygen, and water enter a cell through the ______________. Waste products leave in the same way.
cell membrane
A cell must remain small, so that DNA can control
cellular activities
At the beginning of cell division, a chromosome consists of two
chromatids
The genetic information that is passed on from one generation of cells to the next is carried by ___________________
chromosomes
What regulates the timing of the cell cycle in eukaryotes?
cyclins
The cell cycle describes what happens to cells as they
grow and divide
Which of the following is NOT an advantage of asexual reproduction?
increases genetic diversity
Before cell division, the cell
Copies all of its DNA
Every cell must _______ it's genetic information before cell division begins.
Copy
Chromosomes make up the packages of
DNA
The larger a cell becomes the more de,and the cell places in its DNA- _____________________ causing the cell to grow without limit. Information that controls a cells function is stored in DNA.
DNA overload/ inflammation crisis
It then divided two ___________ cells. Each daughter cell receives a complete set of DNA
Daughter
Each ____________________ gets its wn copy of that genetic information
Daughter cell
During the cell cycle, a cell ___________, _____________ it's DNA, _________ for division, and divides to form ________________
Grows, replicates, prepares, 2 daughter cells
The prokaryotic cell cycle is a regular pattern of
Growth, DNA replication, and cell division
In sexual reproduction the offspring
Inherits some information from both parents
The period between cell divisions is called
Interphase
The rate at which food and oxygen are used up and waste products are produced depends on the cells
Volume
