Plants
This plant structure contains a plant embryo and stored organic nutrients inside a protective coat:
What are seeds?
This type of fungi survive by forming mutualistic relationships; they are a combination of a cyanobacteria and a green algae:
What are lichens?
The________ is the first embryonic opening in the hollow ball of cells called the gastrula:
What is the blastopore?
Gastropods, Cephalopods, and Bivalves belong to this phylum:
What is Mollusca?
Occurs when an extreme phenotype is favored; can occur when a population is adapting to a changing environment:
What is directional selection?
These structures increase the amount of photosynthesis and carbohydrates produced for the plant:
What are megaphylls?
This portion of a plant's vascular system conducts water and minerals:
What is xylem?
Concerning germ layers, this middle layer gives rise to organ systems and the dermis:
What is the mesoderm?
Variation, inheritance, and degrees of successful reproduction are all required for this phenomenon to occur:
What is evolution by Natural Selection?
Two or more extreme phenotypes are favored over any intermediate phenotype:
What is disruptive selection?
Mosses are an example of a __________ plant:
What is nonvascular?
These motile fungi inhabit soil and water; some are plant or animal parasites:
What are chytrids?
_____________ have a body cavity completely lined with mesoderm:
What are coelomates?
Only alleles that are expressed are subject to natural selection; recessive alleles might have greater fitness in a changing environment and may be protected:
What is heterozygote advantage?
Ultimate source of allele differences; introduces new variations in a population for natural selection to act on:
What is genetic mutation?
These types of seedless vascular plants have megaphylls, sori with sporangia located under their fronds, and flagellated sperm:
What are ferns?
This organic polymer forms cell walls, especially wood and bark:
What is lignin?
Repetition of body units:
What is segmentation?
The tendency to mate with individuals of the same phenotype:
What is assortative mating?
All the members of a single species occupying a particular area at the same time and reproducing with one another:
What is a population?
Seed plants have 2 types of spores and two types of gametes. Pollen grains are the drought resistant ________ gametes:
What are male?
Hypothesis that supports the idea that animals descended form an ancestor that resembled a hollow spherical colony of flagellated cells:
What is the Colonial Flagellate Hypothesis?
Pinworms, hookworms, Ascaris; not segmented; free living or parasitic:
What are roundworms?
In this type of genetic drift, species suffer near extinction and only a few survivors go on to produce the next generation:
What is the Bottleneck Effect?
Movement of alleles among populations by migration of breeding individuals:
What is gene flow?
