Living Things
The biosphere is...
What is the sum of all living things on the Earth.
Define Autotroph
make their own food; like plants using photosynthesis
Taxonomy is...
The science of classifying living things, which makes it easier to study them.
A species is
A group of living things that are physically similar and can produce fertile descendants
List the 6 Kingdoms
Eubacteria, Archeabacteria, Plant, Animal, Fungi, Protist
The difference between unicellular and multicellular is...
What is unicellular is to be made up of one cell and multicellular is to be made up of many cells.
Provide two examples of autotrophs.
- Plants
- Algae
- Some bacteria
Provide three examples of heterotrophs
- Animals
- Fungi
- Many microrganisms
The groups in the natural system are called...
What is taxonomic categories, or taxa
Which kingdoms below to the Eukarya Domain?
Plant, Animal, Fungi, Protist
All living things have these characteristics in common...
What is (1) a shared chemical composition, (2) three main life functions (nutrition, sensitivity, and reproduction), and (3) all living things are made up of cells
Reproduction is...
The process by which living things produce new individuals or offspring.
What is the difference between asexual reproduction and sexual reproduction?
Asexual reproduction - one parents produces a new living thing that is identical to the parent
Sexual reproduction - two parents, a male and a female, each contribute a gamete, When the two gametes join, the descendant has characteristics of both parents
Define Classifications
groupings of organisms using similar characteristics
Prokaryotes belong in what domain(s)?
Bacteria and Archea
The four most abundant elements in living thing are...
What is oxygen, carbon, hydrogen, and nitrogen.
The difference between autotrophs and heterotrophs is...
Autotrophs make their own food to have the nutrients needed to make energy.
Heterotrophs eat other organisms to get the nutrients needed to make energy
What is the scientific system used to name living things and who it was first used by
Binomial nomenclature / Carl Linnaeus
There are ____ number of domains , _____ number of kingdoms, and ______ number of species
3 Domains
6 Kingdoms
Millions of species
Explain, what the statement is slightly miss leading; Fungi are multicellular.
Fungi are mostly multicellular but some can be unicellular.
What is taxonomy?
the scientific study on how things are classified
The more classification levels that two organisms share, ________.
the more traits they have in common and more closely related
Describe how species are named
Two Latin words are used for each species. The first word starts with a capital letter and refers to the genus. The second word starts with a lower case letter and refers to the species.
Identify and define the two principal systems of classification
Artificial system - based on physical characteristics (shape, size, color, habit).
Natural system - based on natural relationships by descent from a common ancestor; uses internal and external characteristics, and evolutionary (genetic) relationships
What two kingdoms contain ONLY heterotrophs?
Fungi and Animalia
