produce chlorophyl and carry out photosynthesis
What kingdom do plants come from?
Why use a broader definition to define "plants"?
it allows for the inclusion of plants from which typical plants evolved - long ago algae were the only plants, land plants evolved from these
How old is the earth?
~ 4.6 billion years old
Describe the earliest known fossils
microfossils from ~ 3.5 billion years ago resembled bacteria
As life evolved from its simplest form, what 3 properties did all life share?
1 - ability to grow
2 - ability to reproduce
3 - ability to pass on characteristics (heredity)
this plant lacks chlorophyl - rather than photosynthesis, its roots partner up with fungus and mooch food
What is the traditional definition of plant?
any of a kingdom plantae of living beings that lack locomotive movement or obvious nervous or sensory organs and that possess cellulose cell walls
not traditionally plants, but their roots are integrated with those of other plants
Describe how fungi grow
they grow as collections of cellular filaments - excrete enzymes to break down surfaces and absorb nutrients
fungi and algae working together as a dual organism - they make chlorophyl and carry out photosynthesis
describes the adjoinment of fungi and algae to make lichens
Describe emergent properties
emergent properties describe how things obtain specific patterns and systems as they become more complex when our approach is integrated into many different perspectives and magnitudes
the study of cells
study of plant fossils
study of plant function
describe the central approach to biological sciences
includes the use of testable and repeatable observations and hypotheses in order attain standing theories - which are hypotheses backed up with proof again and again
-this questioning process is important as we expand and focus our minds to uncover the mysteries of the world
