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
