Science Test

List the six kingdoms, characteristics of each, and an example of an organism that belongs in each kingdom.

Kingdom Eubacteria is a kingdom which has single celled organisms. Some bacteria are good for the body while others can cause strep throat. An example of a eubacteria is Staphylococcus. Kingdom Archaebacteria is a kingdom where organisms are single celled and contain no nucleus or specialized organelles. An example of archaebacteria is halobacteria. Kingdom Protista is a kingdom where the organisms can be multicellular or unicellular. They also have a nucleus and specialized organelles. One example of a protist is Plasmodium. The next kingdom is Kingdom Plantae. These organisms are multicellular and have a nucleus, specialized cells, and a cell wall. An example of a plantae is a tree.

To remember the order of Linnaean taxonomy, create a mnemonic device.

Knowledgeable Paisley came over for giant sacks.

List and describe the three domains.

The Bacteria domain contains the common types of bacteria that live in and among us. The Archaea domain contains the bacteria that can live in extreme environments where other organisms could not survive. The Eukarya domain contains multicellular organisms such as plants, animals, fungi, and protists.

Define autotrophic.

an organism can produce its own food such as plants and photosynthesis.

Define Heterotrophic

an organism needs to consume other organisms to survive.

What is classification in science?

involves living things when we classify organisms, we place them into groups based on common characteristics.

How are domains different from kingdoms?

less specific than kingdoms.

What does taxa mean?

means biological classification.

How are organisms classified into kingdoms?

classified into kingdoms by animals, plants, fungi, and 3 types of microscopic organisms. Then, animals are divided into phylum by backbones, no backbones, or exoskeletons. Next, Class - mammals, fish, fowl, reptiles. Order: Carnivore, omnivore, herbivore. Family, things that are alike, Genus, even more alike, family - can reproduce and have fertile offspring.

Taxonomic Keys are made of a series of ____________ that describe physical characteristics of different organisms.

paired statements

What are two different types of passive transport?

passive transports are diffusion and osmosis.

Eukaryotes are found in _______ and animals.

plants

Through advancements, we are now able to classify organisms into three domains by analyzing the _____________.

genetic links

What do living things need to survive?

have food for energy

List the six kingdoms.

1. Archaea 2. Eubacteria 3. Protista 4. Fungi 5. Plantae 6. Animalia

Both traits that they share

1.Dna 2.Cell Membrane 3.Ribosomes

Traits only Prokaryotes have

1.Nucleoid 2.Oldest known fossil 3.Bacteria

Traits only Eukaryotes have

1.Plants and Animals 2.Nucleus 3.Membrane-bound organelles

What is the purpose of a domain?

to classify each and everyone of them into a different domain. We have to use different organisms such as bacteria, archaea, and eukarya.

What role do cell membranes play in prokaryotic and eukaryotic organisms?

to control what substances go in and out of the cell

Why do scientists use binomial nomenclature?

to identify each organism.

What is a shared derived characteristic? What is an example of this type of characteristic?

trait that common ancestors of a group had and passed on to its offspring.

How is a branching tree diagram used?

used to group organisms with other species that have a common organism.

How are taxonomic keys used?

used to identify something.

What other ways can organisms be classified?

using the Linnaean classification.

What would happen if a cell membrane let too much water into a cell?

would stretch and break and the cell would burst.

What is the difference between active transport and passive transport? Which one requires energy?

Active transport requires energy. Passive transport is high to low while active is not.

Eukaryotes and prokaryotes are both surrounded by a _______ ______________

Cell Membrane

Materials move across a cell membrane in a process called _________

Cellular Transport

List the three domains of life.

Bacteria, Archaea, Eukarya

What two elements of the Linnaean system make up an organism's scientific name?

Binomial Nomenclature

Prokaryotes store ____ in a nucleoid.

DNA

List the three domains, characteristics of each, and an example of an organism that belongs in each domain.

Domain bacteria is an organism that lives in soil, water, and even the human body! One organism that belongs in this domain is Botulism. Domain Archaea is an organism that can live in extreme environments where other organisms can't. One example of an archaea is Crenarchaeota. Domain Eukarya has multicellular organisms such as plants and animals. One example of an organism for the eukarya domain is a dog.

List the different levels of classification from broadest to most specific?

Domain, kingdom, phylum, class, order, family, genus, and species

How are organisms classified?

From broad characteristics to specific ones

What is the structure of a eukaryote?

Has a nucleus, multicellular or unicellular, has organelles

What are the characteristics of living things?

Have cells, chemicals, respond to Stimuli, use energy, grow and develop, and reproduce

What is the structure of a prokaryotes

They have no nucleus, they are unicellular, and they have no organelles

What is a species?

a group of individuals that can breed and produce fertile offspring.

Why are organisms classified?

This will make it easier for scientists to study different species

Prokaryotes are better known as ___________.

bacteria

Why is it important to have a system for classifying living organisms?

because classification keeps things neatly organized and helps us make connections between characteristics and relationships.

How do substances move across the cell membrane?

by either using passive or active transport

What are prokaryotes?

cells found in bacteria.

What are eukaryotes?

cells found in plants and animals

A __________ is the most recent ancestral form or species from which two different species evolved.

common ancestor

How are organisms classified into domains?

divided into Domains, based on certain attributes. One part of the organisms are bacteria, one is archaea, and everythings else goes to eukarya.
