Cells and Tissues
Cell type that makes up a photosynthetic layer within the leaf
What is parenchyma?
Cell growth in this region of the root pushes the root tip through the soil
What is the zone of elongation?
This tissue produces xylem to the inside and phloem to the outside
What is the vascular cambium?
The big benefit of asexual reproduction over outcrossing
What is reproductive assurance?
Avoidance of these two things favors the evolution of seed dispersal
What are competition and inbreeding
Habitats where seed dormancy is an effective strategy
What are harsh or variable environments (deserts, arctic, alpine)?
These projections from the zone of maturation are the site of most root absorption
What are root hairs?

What is a fruit?
Trichomes and epidermis are a part of this tissue system
What is the dermal system?
Not the Vegas Strip, but the ____ _____ controls the movement of water and solutes from the root cortex to the root vascular tissue
What is the Casparian Strip?
Air passes through these bark structures to access the interior of a stem
What are lenticels?
Recognition proteins (S-proteins) are formed late during this self-incompatibility system and only 1 pollen S-allele interacts with the pistil
What is gametophytic SI?
This fruit type makes use of other structures besides the ovary, e.g. a strawberry
What is an accessory fruit?
Lignified cell type that provides support/structure to stems
What is sclerenchyma?

What is "far apart"?
Induction of flowering by light cues relies on sensing of light by this organ
What is the leaf?
Dispersal and species-specific enemies drive high seed/seedling survival at intermediate distances from a mother tree
What is the Janzen-Connell hypothesis?
A ____ cell supports sieve tube elements and transfers materials in/out of the phloem
What is a companion cell?
Stem vascular bundles in monocots vs dicots are ____ vs. ______
What are "dispersed" vs. "in a ring"

Who is Your Professor?
This type of reproduction tends to evolve at range edges (where mates are rare)
What is selfing (or asexual reproduction)?
These two frugivore characteristics determine seed dispersal distances in endozoochorous species
What are frugivore movements and gut passage times
