Is a plant vascular or non-vascular if has xylem and phloem?
Vascular
a plants that completes its life cycle in one year is known as a _______________
Annual
Plants typically process ______ and ________ waves of light (hint: colors)
Red and blue
What is apical growth?
Apical growth refers to primary growth, where growth occurs at the roots and shoots of plants.
What is the most prominent gaseous element in our atmosphere?
Nitrogen
This family of plants, currently, is known to have the most species.
Bountiful amounts of what gaseous element in the upper atmosphere led to the creation of the ozone layer?
Oxygen
This plant species makes up one of the largest and oldest known biological organisms in known in the world.
Aspen
What insights may we gain from studying tree rings (aside from age)?
Climate patterns (inferences on temperature and precipitation)
What two primary factors typically influence vegetation communities?
Temperature and Precipitation
This is the point at which a plants capacity to absorb (or photosynthesize) light is reached
Irradiance Saturation
It is suggested that early terrestrial plants developed certain characteristics to adapt to their environment. Which characteristic did early land plants develop to deal with desiccation?
Cuticles (or stomata ok)
Primary differences in photosynthetic pathways are typically related to what cycle?
Calvin or Calvin-Benson cycle
Typically, plants rely on tiny microorganisms to transform this gaseous element into usable forms -- which is critical as this element helps provide the structure necessary for amino acids (which ultimately promote growth and development).
Nitrogen
This relationship between a plant and mycorrhizal fungi is known as a _____________ relationship
Symbiotic
This process involves splitting water molecules into smaller units to gather energy for eventually producing ATP and NADPH
Photolysis
_____________ show evolutionary relationships between plants based on shared characteristics
Cladograms
This family of plant can be resistant to grazing and fire, and are largely pollinated by wind. Meristems typically occur at the soil surface.
Poaceae
This family of plants typically have fused stamens and pistils, in addition to pollen being pooled in masses.
Orchidaceae
Most common photosynthetic pathway - plants with this pathway tend to be less efficient in hot and dry conditions due to photorespiration
C3
What does the acronym PETM stand for? And what was so significant about this event?
Paleocene - Eocene Thermal Maximum. An event that occurred roughly 55 mya, that introduced a lot of greenhouse gases into the atmosphere that significantly changed environmental conditions on earth.
These areas are where new cells are developed, often used as basic units to describe where plants grow.
Meristems
DNA and derived amino acid sequences of the rbcL gene can be used to construct these trees which provide us with a map showing evolutionary change with respect to change based on common ancestry
Phylogenetic trees
Hemicryptophytes - refer to plants where meristem production is where__________?
above at soil surface.
If an embryo develops into a diploid sporophyte, what next does the sporophyte produce via meiosis?
Spores
