Bc Science 9 - Chapter 5

Front 1

cancer

Back 1

The result of an uncontrolled cell division. When cells divide and make more cells even after they are supposed to stop.

Front 2

cell cycle

Back 2

It is the three stages of life of a cell, which includes interphase, mitosis, and cytokinesis.

Front 3

cytokinesis

Back 3

The final stage of the cell cycle, which it separates the two nuclei and cell contents into two daughter cells.

Front 4

interphase

Back 4

The first and longest stage of a cell, the cells carry out the life functions and sometimes prepare for cell division.

Front 5

mitosis

Back 5

This is the shortest and the second stage of the cell cycle. The process in which the duplicated contents of cell and nucleus divide into to equal parts.

Front 6

replication

Back 6

It is a process during which the cell copies the DNA information in the nucleus.

Front 7

spindle fibres

Back 7

Tiny tube-like structures that are made of proteins. They attach to chromosomes during the cell division.

Front 8

sister chromatids

Back 8

These are formed when the DNA replicates during interphase and they are joined together by the centromere.

Front 9

centromere

Back 9

This is the structure that joins two sister chromatids together.

Front 10

early prophase

Back 10

The chromosomes are coiled into x-shapes. The nucleolus and the nuclear membrane will begin to break down. The spindle fibres begins to form.

Front 11

late prophase

Back 11

The chromosomes attach to the spindle at their centromeres, and then the nuclear membrane disappears.

Front 12

metaphase

Back 12

Spindle fibres pull the x-shape chromosomes into a single line that is across the middle of the cell.

Front 13

anaphase

Back 13

The spindle fibres pull the sister chromatids to move to the opposite poles of the cell.

Front 14

telophase

Back 14

A nuclear membrane forms around each set of the chromosomes. The cell is ready to divide.

Front 15

asexual reproduction

Back 15

A reproduction that only requires one parent and produces an offspring that are genetic copies of the parent.

Front 16

binary fission

Back 16

This is a form of asexual reproduction of a single parent cell. It replicates its genetic material and divide it into two different parts.

Front 17

budding

Back 17

An asexual reproduction where areas of an individual do mitosis and grow another organism right on its own body.

Front 18

clone

Back 18

An identical genetic copy pf the organisms parent.

Front 19

fragmentation

Back 19

A form of asexual reproduction, which pieces break off the parent. Then each fragment develops into a clone of the parent.

Front 20

spore

Back 20

Reproductive cells that grows into new individual by mitosis

Front 21

stem cell

Back 21

Cells that have the potential to become many types of cells. There are two different types of stem cells: the embryonic stem cells and the adult stem cells.

Front 22

vegetative reproduction

Back 22

A reproduction in which the special cells are usually in plant cells and plant roots. They divide repeatedly to form the structures that will eventually develop into a plant that is identical to the parent.
