Characteristics of Life
Name the 4 characteristics of living organisms
1. Use energy
2. Contain DNA
3. Respond to Environmental Stimuli
4. Ability to reproduce
First attempt at classification was made by this well known scientist/thinker
Aristotle
True or false, all organisms are composed of cells
True- all day long!!!
True or False Eukaryotic organisms be singe celled?
True !!!!!!!!!!!!!!
What is the process that God created allowing plants to use the energy from the sun to create their own energy
Photosynthesis
Name a living organism and explain how the 4 characteristics apply
(varies)
The science of classification is called
Taxonomy
Name the two major types of cells
Prokaryotic and Eukaryotic
Name the three Domains that have been placed above Kingdoms in the classification system and explain why that change was made
Bacteria
Eukarya
Archaea was discovered and scientists believed it was different enough to warrant its own classification
Bacterial cells are "sticky" what is the cellular anatomical feature that helps them stick together or to surfaces?
Pili
Is a tree alive? Explain how
Has cells with DNA
Uses energy (photosynthesis)
Responds to environment (phototropism)
Reproduces (various)
The father of classification is known as
Carl Linneaus
What is the difference between prokaryotic cells and eukaryotic cells?
Prokaryotic cells have no membrane bound organelles, while eukaryotic cells do.
What is the function of the plasma membrane (there are 2)
Regulate what enters/exits the cell
Maintains the shape of the cell
Cells require motility for movement, what is this anatomical cellular feature called?
Flagella
Organisms that are alive use energy from the environment one of three ways name them
Decomposers (bacteria, fungi)
Producers (algae and plants)
Consumers (everything else)
Name Carl Linneaus' classification structure/heirarchy, which level is the broadest and which is the narrowest?
Kingdom, Phyla, Class, Order, Family, Genus, species
Kingdom is broadest, species is narrowest
Plants and animal cells differ. Name to ways that these cells differ
Various
(Shape, plant cells have chloroplasts- animal cells do not, plant cells have cell walls- animal cells do not, animal cells contain lysosomes while plant cells do not)
What do Archaea and Bacteria have in common?
Both bacteria, both prokaryotic
Name the outermost layer of most bacteria, which makes it hard to destroy
capsule
Omnivore
Carnivore
Herbivore
Omnivore- consume both plant and animal
Herbivore- consume plants
Carnivore-consumes flesh
What is the two name system called for all organisms and what is the rule for writing it?
Binomial Nomenclature-
Genus-capitalized
species- not capitalized
Name 2 organelles and state their function
Various
Name the three Domains and what is contained in each, along with characteristics
Archaea, Bacteria (Monera), Eukarya
Archaea is bacteria in harsh conditions, single pro cell
Bacteria bacteria, single pro cell
Eukarya single or multi cell Fungi, Plant Animal, Protista
Name the three shapes of bacterial cells we have studied include their scientific name
Cocci-spherical
Bacilli- rod shaped
Spirilla-spiral
