Cell

Is the basic unit of a structure & function in an organism.

organism

living things

Unicellular

single-celled organisms

Muiticellular

organisms are composed of many that are specialized to do certain tasks.

Stimulius

a change in an organisms surroundings that cuases the organism to react.

response

an action or change in behaivor.

development

is the process of change that occurs during an organisms life to produce a more complex organism

Spontaneous generation

The mistaken idea that livings can arise from nonliving sources

living things

all living things need water, food, living space, & stable internal conditions to live.

autotrophs

organisms make their own food.

heterotrophs

organisms that do not make their own food.

homeostasis

the maintenance of stable internal conditions

classification

is the process of grouping things based on their simularities.

taxonomy

the scientific study of how living things are classified

biologist do..

use classification to organize living things into groups so that the organisms are easier to study.

binomial nomenclature

is a naming system Linnaeus used.

Genus

a classification groups that contain similar, closley relate organisms.

species

is a grouping of similar organisms that can mate with each other & produce offspring that can also mate & produce.

classification system

Domain, Kingdom, phylum, class, order, family, genus, & species

Three domains of life...

Bacteria, Archaea, & Eukarya

In the Eukarya there is....

Protists, Fungi, Plants, & Animals

Prokaryotes

are organisms whose cells lack a nuecleus.

Nucleus

is a dense area in a cell that contains nucleic acids-the chemical instructions that direct the cell's activity. AKA- The Brain

Eukayotes

Orgainsms with cells that contain nuclei.

Protists

is any Eukayotes organism that can't be classified as an animal, plant, or fungus. They can be heterotophs or autotrophs.

Fungi

Most fungi is multicellular & ALL Fungi are heterotrophs.

Plants

multicellular & are autotrophs. They provide a ton of heterotrophs with food.

Animals

multicellular & are all heterotrophs.

Cells are..

the basic units of structure & function in living things.

Microscope did..

made it possible for people to discover & learn about cells.

Microscope

is an instrument that makes small objects look larger.

Robert Hooke

built the first compound microscope. in 1663 he used his microscope for the first time. He saw some the firt cells ever seen my a human eye.

Anton Van leeuwenhoek

He made the first simple microscope. he discovered the cells around the same time Robert Hooke did.

Matthias Schleiden

In 1838, he concluded that all plants are made up of cells.

Theordor Schwann

in 1834, he concluded all animals were made up of cells

Rudolf Virchow

In 1855, he concluded that cells are formed only from cells that already exist.

The Cell Theory Rule #1

All living things are composed of cells.

The Cell Theory rule #2

Cells are the basic units of structure & function in living things.

The Cell Theory rule #3

all cells are produced from other cells

Compound Microscope

Uses more than one lens.

Resolution Microscope

Has the abililty to clearly distinguish the indivdual parts of the object.

Electron Microscope

Uses a beam of electrons instead of of light to produce a magnified image.

Organelles

Carry out specific functions within the cell.

Cell Wall

Helps protect & support the cell.

Cell Membrane

Controls what substances come into & out of a cell.

Nucleus

The cells control center directing all of the cell's activities.

Nuclear Envelope

Protects the Nucleus

Chromatin

Contains genetic material, the instructions for directing the cell's function.

Nucleolus

Where ribosomes are made.

Cytoplasm

The region between the cell membrane & the nucleus.

Mitochondria

known ar the "powerhouse" of the cell because they convert energy in food molecules to energy the cell can use to carry out its functions.

Endoplasmic Reticulum

Passageways that carry proteins & other materials from one part of the cell to another.

Ribosomes

Function as factories to produce proteins.

Golgi Bodies

Receive Protein & packages them to distribute them to other parts of the cell.

chloroplasts

Captures Energy from the sunlight & uses it to produce food for the cells.

vacuoles

Are the storage areas of cells.

Lysosomes

Are small, round structures containing chemicals that break down certain materials in the cell.

why did the tomato invite the fungi to the party?

because he was a FUN-GUY!!!
