Biology - Mitosis And Asexual Reproduction | Ms. Lester

The survival of a species depends on

______, and the ______ of new individuals

reproduction

Asexual reproduction involves

only one parent, the new

organism develops from ____

of the parent

cells

In ___ ___ there are two parents, each contributes a special cell to the new generation

sexual reproduction

In Sexual Reproduction The two sex cells are known as _____ two _____ fuse to form the first cell of the new generation

gametes

It is called ____ When the sperm puts its DNA into the egg cell

FERTILIZATION

All cells arise from other cells by __ __

cell division

What is a type of cell division that results in the formation of two new cells?

Mitosis

What type of cells are formed through mitosis?

Genetically identical cells

___ is a type of cell division that results

in the formation of two new cells that are genetically identical to each other.

Mitosis

During mitosis:

1. The __ replicates

DNA

During mitosis:

1. The ___ divides,

forming two new cells

cytoplasm

Each species has a characteristic

number of ___

chromosomes

During mitosis, two new cells are created, they are genetically ___ to each other

identical

In between cell divisions the

chromosome material is in the

nucleus in the form of loose

___ ___

chromatin fibers

During __ __ the

chromosomes are condensed into

distinct X shaped structures.

cell division

Before the cell division begins the

DNA is copied forming two identical

strands of __ material

genetic

One strand of DNA is distributed to each of the two new cells that form when the cell ___.

divides

A cell passes through five stages

using cell division

Interphase

Proohase

Metaphase

Anaphase

Telephase

The cell spends most of its life in

the non-dividing phase called __

interphase

During __ the cell carries in

its life processes including DNA

synthesis for the replication of

chromosomes

interphase

During __ the cell prepares

for cell division

prophase

___: The chromatic condenses into

chromosomes the nuclear

membrane breaks down the

centrioles move to opposite poles

in the cell

Prophase

During __ the

chromosomes line up in the center

of the cell along the equator

metaphase

During __ the chromosomes

split at the centromeres and move

into two groups

anaphase

During __ the cell completes

the nuclear division

telophase

__: Two new nuclear membranes form.

The chromosomes unwind to form

chromatin

Telephase

The division of the cytoplasm and cell organelles is called __

cytokinesis

In __ cells the cell membrane pinches in at the equator to

separate two new cells

animal

In plants cells a new cell wall forms between the two __ cells

daughter

The growing cell wall is called the __ __

cell plate

During interphase the cell carries in

its life processes including DNA

synthesis for the replication of

__

chromosomes

During Telophase -two new nuclear membranes form.

The chromosomes unwind to form

__

chromatin

Animal cells have — while plant cells do not

centrioles

Multicellular organisms use — for growth and repair of tissues

mitosis

Mitosis is a kind of —

Cell division

Mitosis is a kind of Cell division results in the formation of 2 — — that are genetically identical

Daughter cells

Mitosis is used for — and — of tissue

Growth and repair

Unicellular organisms use mitosis for

asexual reproduction

Some multicellular organisms CAN or CANNOT also reproduce asexually using mitosis.

Can

Unicellular organisms use mitosis to —

reproduce

— — splits a single cell into two equal parts

Binary fission

This reproduction is asexual and results in offspring that are genetically identical to one another.

Binary fission

Some organisms use mitosis to reproduce the nucleus, but divide the — unequally.

cytoplasm

Some organisms use mitosis to reproduce the —, but divide the cytoplasm unequally.

nucleus

Some organisms use mitosis to reproduce the nucleus, but divide the cytoplasm unequally

This method is called —

budding

Common in yeast "yeast budding"

— can also reproduce asexually by budding

Hydra

Hydra can also reproduce asexually by —

budding

In some multicellular organisms such as bread mold, specialized cells called spores are produced in large numbers by mitosis

This process is called —

sporulation

— are generally surrounded by a tough coat that enables them to survive harsh environments and environmental conditions

Spores

— is the replacement of lost or damaged body parts.

Regeneration

— requires undifferentiated cells (unspecialized)

Regeneration

— generally show a greater capacity for regeneration than vertebrates

Invertebrates

Invertebrates have many more undifferentiated cells then — have

Vertebrates

A lizard may grow back a lost tail, this is called —

Regeneration

— — occurs when new plants develop from the roots, stems, or leaves of a parent plant.

Vegetative propagation

Sometimes cells undergo abnormal and rapid divisions, resulting in growths called —

tumors

— can invade surrounding tissues and organs and interfere with their normal activities

Tumors

Tumors occur in a group of diseases called —

Cancer

Cancer can be treated with — or chemotherapy.

radiation

Cancer can be treated with radiation or —.

chemotherapy

Early detection of — can mean the difference between life and death.

Cancer

Mitotic cell division is also called

Mitosis

Meiotic cell division is also called

Meiosis
