Gravitropism is a growth response of plants that implies that plant stems grow up and roots grow downward. This is assisted by structures in the root caps that act as gravity sensors. These are called:
amyloplasts
A plant with parallel veins and floral parts in threes would be classified as:
a monocot.
A liver fluke infection is most commonly found in persons who:
eat undercooked fish.
According to modern animal phylogeny based on molecular data, nematodes fall into which of these groups?
ecdysozoa
According to modern animal phylogeny based on molecular data, which of the following is a monophyletic group?
Bilateria
This phylum of cone-bearing gymnosperms is distributed worldwide in cold or dry regions. Many members have needle-shaped leaves with thick cuticles and stomata in pits. This phylum includes the oldest tree (named “Methuselah”) and the tallest tree.
Coniferophyta (conifers)
This group of organisms do not moult, and are characterized by having a lophophore (for feeding) and a trochophore (larva with a ring of cilia around the middle). They are:
lophotrochozoans
These animals are radially symmetric and more complex than Cnidarians. They have anal pores, are bioluminscent and move using comb-like plates of fused cilia (largest animals to use cilia for locomotion). They are commonly called comb jellies or sea walnuts and belong to:
Ctenophora
Which of the following elements is a micronutrient in plants?
Fe
Cu
The absorption of water by root hairs is accomplished by:
active transport of ions, followed by water coming in by osmosis
Of the following farming practices to replenish soil fertility, which is most likely to pollute water supplies and damage ecosystems?
adding commercial fertilizers
The plant tissue type that gives rise to all other plant tissues or cell types is:
meristem
A plant with small, odorless flowers that have reduced or no corollas and that make copious amounts of pollen is most likely pollinated by:
the wind
Members of this phylum are found mostly in freshwater. They have a ciliated food-gathering organ at the tip of their head called a corona. The beating of the cilia gives the appearance of a turning wheel. Some members of this phylum make extensive use of parthenogenesis for reproduction
Rotifera (rotifers)
Sessile adults with a body made of spongin and spicule fibres belong to which phylum? They typically live in the ocean and have a cellular level of development.
Porifera (sponges)
The term “angiosperm” means:
seed enclosed in a vessel
Members of this phylum do not have bilateral symmetry; they may have both polyp and medusa forms as adults, and the larval stage is called planula. They can reproduce asexually or sexually.
Cnideria (stinging-celled animals)
The tissue that directly gives rise to secondary phloem and secondary xylem is
vascular cambium
The members of this class comprise the largest class of Cnidaria and can exist as solitary or colonial animals. They have a dominant polyp form, usually with no medusae
Anthozoa (sea anemones and corals)
Which layer of cells controls the movement of nutrient minerals entering the xylem in the root's interior?
endodermis
Which hormone, first isolated in the 1920s by Kurosawa from fungus affecting rice, stimulates shoot elongation, growth of dwarf plants and hastens seed germination ?
gibberellin
These animals are hermaphroditic, have a clitellum during the breeding season, and are mostly parasitic, many of them feeding on the blood of vertebrates including humans. They are dorsoverntrally flattened and have suckers on either ends of their bodies. They belong to the class or subclass:
Hirudinea (leeches)
Which kind of plants lose and replace their leaves continuously in small numbers through the year, but do not lose and replace all leaves together in response to the seasons
evergreen
For most plants, the preferred soil type is a mix of mineral types that hold water well but not too well. Some soils hold water too well (electrostatic attraction), and this type of soil is called
clay
Plants parts are often adapted to the environments plants live in. Cyress and mangrove trees that live in swampys areas often have spongy, air filled “knees” emerging up from their roots, with large lenticels above the level of the water to allow oxygen in. These are called
stolon
A psuedocoelom is located:
between mesoderm and endoderm
According to physiological evidence and some genetic data, which of the following has the best chance of actually being a grade that would form a clade with flowering plants?
phylum Gnetophyta
