Is the basic unit of a structure & function in an organism.
organisms are composed of many that are specialized to do certain tasks.
a change in an organisms surroundings that cuases the organism to react.
an action or change in behaivor.
is the process of change that occurs during an organisms life to produce a more complex organism
The mistaken idea that livings can arise from nonliving sources
all living things need water, food, living space, & stable internal conditions to live.
organisms make their own food.
organisms that do not make their own food.
the maintenance of stable internal conditions
is the process of grouping things based on their simularities.
the scientific study of how living things are classified
use classification to organize living things into groups so that the organisms are easier to study.
is a naming system Linnaeus used.
a classification groups that contain similar, closley relate organisms.
is a grouping of similar organisms that can mate with each other & produce offspring that can also mate & produce.
Domain, Kingdom, phylum, class, order, family, genus, & species
Three domains of life...
Bacteria, Archaea, & Eukarya
In the Eukarya there is....
Protists, Fungi, Plants, & Animals
are organisms whose cells lack a nuecleus.
is a dense area in a cell that contains nucleic acids-the chemical instructions that direct the cell's activity. AKA- The Brain
Orgainsms with cells that contain nuclei.
is any Eukayotes organism that can't be classified as an animal, plant, or fungus. They can be heterotophs or autotrophs.
Most fungi is multicellular & ALL Fungi are heterotrophs.
multicellular & are autotrophs. They provide a ton of heterotrophs with food.
multicellular & are all heterotrophs.
the basic units of structure & function in living things.
made it possible for people to discover & learn about cells.
is an instrument that makes small objects look larger.
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.
In 1838, he concluded that all plants are made up of cells.
in 1834, he concluded all animals were made up of cells
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
Uses more than one lens.
Has the abililty to clearly distinguish the indivdual parts of the object.
Uses a beam of electrons instead of of light to produce a magnified image.
Carry out specific functions within the cell.
Helps protect & support the cell.
Controls what substances come into & out of a cell.
The cells control center directing all of the cell's activities.
Protects the Nucleus
Contains genetic material, the instructions for directing the cell's function.
Where ribosomes are made.
The region between the cell membrane & the nucleus.
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.
Passageways that carry proteins & other materials from one part of the cell to another.
Function as factories to produce proteins.
Receive Protein & packages them to distribute them to other parts of the cell.
Captures Energy from the sunlight & uses it to produce food for the cells.
Are the storage areas of cells.
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!!!
