Science IMPRTRNT DEFINITIONS

The height of the crest trough in a wave.

AMPLITUDE

The number of cycles in a wave, unit of time.

FREQUENCY

A type of energy made of photons that move as a transverse wave.

LIGHT

Waves where the disturbance moves in the same direction as the wave.

LONGITUDINAL WAVE

The material (WATER, AIR, GROUND) that the waves pass through.

MEDIUM

Vibrations that move through matter and move as longitudinal waves.

SOUND

Waves where the disturbance moves perpendicular to the direction of the wave.

TRANSVERSE WAVE

The distance between two peaks or two troughs.

WAVELENGHT

Water turns from liquid to a gas when it evaporates.

EV APORATION

After evaporation, water vapor can cool and condense into liquid, often forming clouds.

CONDENSATION

Strong winds can blow clouds of water many miles away, transporting them to other areas.

TRANSPORT

Occurs when rain, snow, hail and sleet fall from the sky.

PRECIPITATION

A significant/large amount of water will be absorbed into the ground after precipitation.

SURFACE RUNOFF

This occurs when water that has fallen as precipitation is absorbed into the ground.

INFILTRATION

Plants need to maintain a constant stream of water to their leaves for transport and support.

TRANSPIRATION

BUDDING

The way that single-celled fungi like yeast reproduce, like binary fission.

BINARY FISSION

The way bacteria reproduce is very similar to mitosis.

MITOSIS

Cell division for growth and repair - makes identical daughter cells.

TUBERS

An underground nutrient storage that some plants use to grow into new plants.

CORMS

and underground nutrient storage used by some plants, like tubers, and they grow right next to the parent plant’s stem.

GERMAINATION

The name of the process when seeds start to grow requires water, oxygen and the right temperature for the type of seeds.

HORMONES

Chemicals that act as messengers in living things are produced by glands and are often moved around the body through the bloodstream.

WHAT IS THE TERM MRS GREN

MOVE - RESPIRATE - SENSES - GROW - REPRODUCE - EXCRETE - NUTRISHON

SEXUAL REPRODUCTION

Reproduction involving two individuals creates variation in offspring.

ASEXUAL REPRODUCTION

Making more than copies of the original organism, they are all identical clones.

MEIOSIS

Cell division for producing gametes occurs in the testes and ovaries and makes cells with half the original chromosome number.
