Which of the following animals is not a common pollinator of flowering plants?
Definition All of the above are common animal pollinators of flowering plants. Term What is the first step that occurs in the process of angiosperm reproduction after a pollen grain lands on a stigma of the correct species?
Definition A pollen tube forms to carry the sperm cells towards the ovary. Term Which of the following is the proper sequence of events occurring when a flowering plant reproduces? Definition meiosis; pollination; fertilization; embryo formation.
Term "Double fertilization" in angiosperm plants refers to:. Definition the fusion of one sperm cell with the egg, and another with two nuclei of the endosperm-forming cell. Term The sperm cells in a pollen grain can serve different purposes. Which of the following could NOT happen to a sperm cell in nature? Definition Both c and d could not occur in nature.
Term By what process do the haploid cells in a new pollen grain produce two sperm cells? Definition mitosis. Term Which of the following is NOT a method by which plants reduce the possibility of self-fertilization?
Definition All the above are methods used by plants to reduce self-fertilization. Definition The population can better keep up with changing conditions. Term From an evolutionary standpoint, why do many flowers have attractive colors and smell good?
Definition to facilitate the transport of male gametes to female structures. Term The phrase "double fertilization" in angiosperms is best described by which of the choices below?
Definition Each pollen grain contains two sperm cells and one leads to the fertilization that produces the embryo and the other leads to the fertilization that produces the endosperm.
Term Some fruits are designed to be attractive food for animals. Other fruits that rely on animal dispersal are:. Definition sticky or covered with clingy burrs. Term Which of the following is NOT true about a plant seed? Definition It is fleshy, juicy, and edible. Term Why is staggered maturation a good mechanism for reducing self-fertilization?
Definition By the time one gamete is ready, the other is no longer viable or even present for fertilization to occur. Term The outer green leaflike portions of a flower enclose the inner petals like a protective barrier. Can you name this outermost portion from the choices below? Definition the sepals.
Term Aspens have adapted to cold temperatures on the Orkney Islands by:. Definition reproducing asexually through root suckers. Term When you are seven years old, you write your name four feet above the ground, into a 12 foot tall bamboo plant. You spend the next ten years in a special home for vandals. When you get out the bamboo is 24 feet tall. At that time, how far above the ground will your name be? Definition 4 feet. Term Which of the following is the most plausible explanation for why fruits evolved in plants?
Definition To aid in the dispersal of the seeds. Term In flowering plants, meiosis occurs:. Definition in both the ovule and the anther. Term The knots we see in wood represent:. Definition places where branches were connected to the trunk. Term When you are seven years old, you write your name four feet above the ground, into a 12 foot tall bamboo plant.
You spend the next ten years in a special home for vandals. When you get out the bamboo is 24 feet tall. At that time, how far above the ground will your name be? Definition 4 feet. Term Which of the following describes an alternative to sexual reproduction employed by most plants? Definition sprouting such as through root suckers. Term The endosperm that forms at the time of fertilization comes from:. Definition the fusion of a sperm cell with the central cell of the embryo sac.
Definition The population can better keep up with changing conditions. Term The stamens of a flowering plant are broken down into two separate parts.
Definition filament; anthers. Term Meristem cells left behind as the top of a plant grows higher, are:. Definition dormant. Term The phrase "double fertilization" in angiosperms is best described by which of the choices below? Definition Each pollen grain contains two sperm cells and one leads to the fertilization that produces the embryo and the other leads to the fertilization that produces the endosperm. Term Fruit develops from a plant's:.
Definition ovary. Term Unlike in animals, most of a tree's cells are:. Definition dead. Term The common term for the action of transferring pollen grains from an anther onto a stigma is:. Definition pollination.
