Name three Characteristics of living things.
Movement Respiration Sensitivity Growth Reproduction Excretion Nutrition
Define: Movement
Changing position of a part or all of the body.
Define: Respiration
The breakdown of food molecules inside living cells to release the energy
Define:Sensitivity
The ability to sense and respond to changes in the internal or external environment.
Define: Growth
The permanent increase in (dry) mass, size and/or number of cells.
Define:Reproduction
Producing organisms of the same type
Define: Excretion
The removal of metabolic waste, toxic molecules and substance in excess of requirement from the body
Definition:Nutrition
Taking in substances needed for growth, respiration and repair.
True or false: Plants turn away from the light and their root grows into the soil.
False:Plants turn TOWARDS the light and their root grows into the soil.
What are the 5 kingdoms of living organisms?
Prokaryotic Monera -Together they form the tree of life. Protista Fungi Plantae Animalia.
How are the different kingdoms classified?
They are classified by basic similarities
Which is the simplest of the organisms?
Monera
What is a prokaryotic cell?
A cell that has no membrane bound nucleus or organelles; that is, there are no structures inside the cell
Some monera can produce their own food by photosynthesis (using energy from the sun to produce food) like plants do, but many cannot.
Some have whip like flagella that allow them to move. Bacteria and blue-green bacteria belong to the monera.
Since the adoption of the five kingdoms, science has determined that some prokaryotes are so
different from the rest that the kingdom must be subdivided.
These organisms, which evolved along a completely different route, tend to live in extremely harsh environments. They are called archaeobacteria (sometimes spelled archeobacteria). Thus, the kingdom monera may soon be
divided into two: archeobacteria and eubacteria, making six kingdoms.
What does protista consist of?
single-celled and multicellular organisms..
Define:Eukaryotes
Protista are eukaryotes: a eukaryotic
cell has a membrane-bound nucleus and other organelles inside, separate from the rest of the cell
contents.
What does fungi consist of?
Fungi include both single-celled (yeasts) and multicellular (molds, mushrooms etc.) organisms
that are generally visible to the naked eye.
Most protista can move. Some produce their own food by photosynthesis; others must ingest other living things. Some algae, diatoms, protozoa eg. amoeba and paramecium are
examples of protists.
Some are quite large. Fungal cells have nuclei;
however, they don’t move on their own, nor do they make their own food (heterotrophic).
Most fungi get nutrients from decaying organic material.
Some are used by humans for medicinal and
dietary purposes.
They digest their food outside the body using enzymes. So they are usually found living in or on their food, which can be dead or living organisms.
Plantae includes the plants: living things that don’t move, and that produce their own food through photosynthesis.
Plants are multicellular, composed of eukaryotic cells. Plants are generally green, visible to the naked eye, and found in great diversity in many environments on Earth.
This kingdom includes mosses, ferns, conifers and flowering plants.
Flowering plants are called angiosperms because they have true flowers and so make seeds. The seeds are formed when an egg or ovule is fertilized by pollen in the ovary. The ovary is within a flower.
