Life Science Unit Ccs 1

Front 1

Adaptation

Back 1

A characteristic that helps an organism survive in its habitat.

Front 2

Asexual Reproduction

Back 2

Reproduction that involves only one parent, producing offspring that are genetically identical to the parent.

Front 3

Biome

Back 3

A large geographic region with its own characteristic group of plants and animals. Also, a distinct type of environment, such as oceans, deserts, tropical rain forests, and the frozen Arctic tundra.

Front 4

Camouflage

Back 4

An adaptation that causes an organism to blend in with its environment.

Front 5

Chromosome

Back 5

Tiny threadlike structures found in the nucleus of a cell that carry genetic information.

Front 6

Cleavage

Back 6

Rapid cell division that results in smaller, identical cells that allows a zygote to develop into an embryo.

Front 7

Cloning

Back 7

The process of creating an exact copy of a biological unit (a DNA sequence, cell, or organism) from which it was derived, especially by way of biotechnical methods.

Front 8

Egg cell

Back 8

The female sex cell.

Front 9

Embryo

Back 9

An organism in its early stages of development, especially before it has reached a distinctively recognizable form.

Front 10

Fertilization

Back 10

The joining of an egg cell and a sperm cell during sexual reproduction to begin the development of a new individual.

Front 11

Gamete

Back 11

A cell - sperm or egg - used in sexual reproduction.

Front 12

Gene

Back 12

A piece of genetic information that influences a trait.

Front 13

Genetic information

Back 13

Information that determines traits and is stored in chromosomes.

Front 14

Germination

Back 14

The beginning of growth, as of a seed, spore, or bud when conditions are favorable.

Front 15

Hibernate

Back 15

An adaptation where it is to enter a sleep like state of reduced body activity; how some animals survive the winter.

Front 16

Meiosis

Back 16

A type of cell division that produces the sex cells - sperm and egg.

Front 17

Migrate

Back 17

An adaptation in which a community moves from one environment to another, where conditions are more favorable.

Front 18

Mitosis

Back 18

Cell division in which a parent cell splits into two identical daughter cells, each with a full set of chromosomes. Asexual reproduction is carried out by mitosis. Also, cell maintenance in a multicellular organism is carried out by mitosis.

Front 19

Modern cell theory

Back 19

1) All living things are composed of cells. They may be unicellular or multicellular.
2) The cell is the basic unit of life.
3) Cells arise from pre-existing cells.

Front 20

Reproduction

Back 20

The life process by which organisms produce new individuals, or offspring.

Front 21

Sex cells

Back 21

Cells that combine during sexual reproduction, sperm and egg.

Front 22

Sexual reproduction

Back 22

Reproduction that involves two parents, producing offspring that are not identical to either parent.

Front 23

Sperm cell

Back 23

The male sex cell.

Front 24

Traits

Back 24

Inherited characteristics, either physical or behavioral.

Front 25

Vegetative propagation

Back 25

A method of plant propagation not through pollination or by seeds or spores but by way of separating new plant individuals that emerge from vegetative parts, such as specialized stems, leaves and roots and allow them to take root and grow.

Front 26

Zygote

Back 26

A fertilized egg cell that will undergo cleavage to become an embryo.
