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.

Some flowering plants will self-pollinate and self-fertilize, the most extreme form of inbreeding. What is the major disadvantage of this lifestyle for such plants?

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

Dry fruits that have wing-like structures (eg: maples) or parachute-like structures (eg: dandelions) usually aid seed dispersal by:

According to modern animal phylogeny based on molecular data, which of the following is a monophyletic group?

Bilateria

Seed coats, which functions to protect plant embryos and allow them to stay dormant, are formed by:

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

Rhizomes, tubers, corms, and stolons are examples of modified:

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

This Carnivorous plant has leaves with three sensory hairs that when brushed against by insects, triggers trap to shut, eats mostly ants and grasshoppers

Which of the following elements is a micronutrient in plants?

In seed plants the _____________________________ generation is dominant

Growth from apical meristems, generally resulting in an increase in the length of a plant, is referred to as:

The absorption of water by root hairs is accomplished by:

active transport of ions, followed by water coming in by osmosis

According to modern classifications based on DNA sequencing information:

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

The root structure or zone that includes the root apical meristem and is called the:

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

A flower that develops with only sepals and carpels is

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)

If you see a blue flower with "nectar guide" stripes best seen in ultraviolet light and stripes or nectar guides leading down to the nectar offered as a reward, it is likely pollinated by:

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 root structure or zone where cells elongate upto 10 times their original length is called the

The tissue that directly gives rise to secondary phloem and secondary xylem is

vascular cambium

What tissue conducts water and dissolved minerals from the roots to the stems and leaves?

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)

Within the ovules of Gymnosperms, the female gametophyte is surrounded by 1-2 integuments which are cell layers that serve a protective function. This integument has an opening that allows sperm to enter. The opening is called:

Which layer of cells controls the movement of nutrient minerals entering the xylem in the root's interior?

endodermis

The plant hormone that affects opening and closing of stomata, that promotes bud dormancy, and that will produce a yellowed area when applied to a green leaf is:

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

This phylum of acoelomate animals comprises of species that are mostly hermaphroditic that have internal fertilization, asexual reproduction is possible in many species, Not all have a digestive tract, those that do Are incomplete with opening in mouth and anus; have no circulatory system

phylum of vascular, seed-bearing plants that are genetically similar to angiosperms has only about 70 living species in three genera, including bizzare plant found in african deserts Welwitschia.has two leathery leaves that grow continuously form the base and vessels in xylem

Members of this monophyletic group have only about 200 living species in the tropics, most of them in danger of extinction. Are slow growing, many look like Palm Trees but reproduce using cones. Largest known sperm

this phylum of pseudocoelomate animals are extremely common in soil. Many are important plant parasites, and some infect humans

An important lab animal from this phylum is Caenorhabditis elegans, which is primarily used to study developmental genetics.

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
