Activity 1 Flashcards
What does plant and other green organisms do?
they have a capacity to produce oxygen and remove the large amounts of carbon dioxide given off by all living organisms as they respire
What is greenhouse effect?
is a heat that is trapped close to the surface of the Earth by “greenhouse gasses”. Heat trapping gasses can be a blanket wrapped around the Earth

What is Dendrochronology?
study of climate change and past events
deals with determining past climates by examining the width and other features of tree rings
What is algae?
they not only produce oxygen, but also utilize the waste of carbon dioxide produced by respiration and also produces food
What is closed system?

What is testing?
will determine whether it is correct or incorrect
Scientific method pyramid
asking question
formulating hypothesis
experiments

what is variable
a specific aspect that can be changed
what is control
sample that remains the same throughout the expermient
what is data
bits of information
what is principle
formulation of a useful generalization
what is theory
group of generalizations that helps us understand something
what is microscope

1632-1723
What is modern microscopes
can produce magnifications of more than 200,000 times and are leading almost daily to new discoveries in biology

what is forensic laboratories
fragments of plant tissues found on clothing or under fingernails to determine where a crime took place
what is heredity
passing of traits from parents to their offspring
what is paleobotany
study of plant fossils
what is plant physiology
concerned with plant “normal” function
who is J.B van Helmont
the first to demonstrate that plants don’t have the same nutritional needs as animals
what is photosynthetic activity
the tree absorbed all the water that’s why it became large
what is cloned genes
units of heredity that are found mostly within the nuclei of cells
who are the taxonomists
botanists who specialized in the identifying, naming, and classifying the plants
who is carolus linnaeus
the one who created the system of naming and classifying organisms
what is plant taxonomy
involves describing, naming and classifying organisms
what is plant systematics
science of developing methods for grouping organisms
related field, but is broader than taxonomy

the one who discovered the genetics
what is plant breeding
changing the traits of plants in order to create another desired characteristics
what is genetic engineering
the transfer of genes from one organisms to another
what is cell biology
science of cell structure and function, how cell multiply and how their various components perform and integrate a variety of functions
what is another term of cell biology
cytology

which use a beam of electrons to examine objects on very fine scale
what is economic botany and ethnobotany
focus on practical uses of plants and plant products
