Metabolism
*All the chemical reactions in an organism
-in multicellular organisms different cells capable of performing different tasks.
-different parts perform different jobs.
-but all of the work gets done.
Autotrophs
-an organism capable of living exclusively on inorganic materials, water and some source of sunlight of chemically
-turn simple inorganic compunds into complex organic compounds.
-if don't use sunlight but reduce molecules for energy source.
-(chemosynythesis)
Heterotrophs
-can't live without autotrophs
-requires organic material from autotrophs for respiration (break down of sugars).
Catabolism
*Break down reactions
-energy released
-break covalent bonds between atoms.
Anabolism
*Build up reactions
-synthesis from broken down materials
-require an energy imput.
ingestion
taking in of needed molecules
transportation
the movement of molecules in an organism
assimilation
absorption of molecules
digestion
tearing down of molecules
excrete
get rid of wastes
Photosynthesis
-reverse reation of cellular respiration
-builds sugars from carbon dioxide
-basis of physical wealth on the planet-builds biomass
asexual
mitosis exact duplication
sexual
uniting of sex gametes within species leads to more biological variation
determination
related to DNA gene regulation
differentiation
morphological changes to suit function
growth
increase in the size and the number of cells
death
loss of cells
-can be programmed genetically
atoms
-C, N O, H, P, ect.
-the simplest form an "element" can take and still have its properties
Molecules
two or more atoms joined together in a specific ratio and can be divided into two groups
-organic
-inorganic
organic
-based on carbon and hydrogen atoms
-ex: carbs, proteins, fats, crude oil, nucleic acids ect.
inorganic
-not composed of carbon and hydrogen atoms
-ex: carbon dioxide, water, nitric acid, sulfur dioxide
cells
*the basic unit of organic (carbon based) life
-many types but basic style is same (modification according to function)
-single cell can perform all life functions: capable of independent existence and reproduction
-cellular level consists of surrounding fluid (extracellular fluid)
-many organisms are sigle celled called "microorganisms"
Tissue
-a set of cells that function in the same way
-animal tissure types-epithelium, connective, muscle, and nerve
Organ
multiple tissure area that performs one function
Organ system
a group of organs that perform a single job
organism
any complete living thing
species
individuals capable of interbreeding freely with one another to produce viable offspring
population
a group of organisms tht coexist at the same time and in the same place and are capable of interbreeding.
habitat
groups of populations existion in the same area
ecosystem
the oragnisms of a particular habitat together with the physical (non living) environment
biosphere
the sum of all earth's ecosystems.
Emergent properties
1. combinations of above give unique properties not found in lower levels.
2. the whole is greater than the sum of the parts.
ex: an organism is born and dies, but only a population has a birth and a death rate.
monera
single celled bacteria; prokaryotic-no nuclear membrane
Protista
Single or multicellular; eukaryotic has nuclear membrane
Fungi
absorb materials from surrounding environment; decomposers has nuclear membrane
Plantae
primarily multicellular, but some unicellular; photosynthesis; autotrophs, has nuclear membrane
Anamalia
multi-cellular, eukaryotic, hetertophs, has nuclear membrane
science
an attepmt to discover order in nature and use that knowledge to make predictions and projections
scientific data
facts from observations and measurement
scientific hypothesis
an educated guess that explains a scientic law or scientific facts
models
simulates complex processes and systems
scientific theory
if many experiments by different scientists support a model or a hypothesis, well tested and highly accepted
scientific method
-way in which scientists gather data and formulate and test scientific hypothesis
-a set of questions with no particular rule for answering them there are many methods to scientific reasearch.
Basic Life Processes
characteristics found in all living things from sigle celled to multicellular- no single way to group these qualities.
5 kingdom classification
monera,
protista,
fungi,
plantae,
anamalia
