Question 1

Which component of the flowering plant is considered the female portion of the plant?

Accepted Answer

The carpel is considered the female portion of the flowering plant as it contains the ovules, which develop into seeds after fertilization. The stamen is the male reproductive structure, the style is part of the carpel, and the corolla is the collective term for the petals of the flower.

Question 2

When a monocot such as corn germinates, the immature leaves are covered by a _____ while the radicle is covered by the _______.

Accepted Answer

Monocots such as corn have a protective sheath called the coleoptile that covers the immature leaves as they emerge from the soil. The radicle, or embryonic root, is covered by a sheath called the coleorhiza. Therefore, the correct option is C.

Question 3

Which of the following statements is NOT true about the life cycle of flowering plants?

Accepted Answer

The female gametophyte is not the seed. The female gametophyte produces the egg cell, which is fertilized by a sperm cell to form the seed.

Question 4

Match the layers of a pericarp with their correct description.

Accepted Answer

The answer of Match the layers of a pericarp with...

Question 5

Which of the flowering plant structures is used to attract a specific type of pollinator?

Accepted Answer

Petals are often brightly colored and/or have a sweet scent to attract specific pollinators such as bees, butterflies, or hummingbirds. Stamens and carpels are the reproductive structures of a flower and are not specifically used for attraction. Sepals are often green and protect the developing flower bud, but they may also aid in attracting pollinators by providing a landing platform.

Question 6

Seeds require _____________ for germination to occur.

Accepted Answer

All of the choices are required for germination to occur. Seeds need oxygen for increased metabolism, adequate warmth, and adequate water to break down the seed coat and begin growth.

Question 7

The structures in the outermost ring of floral structures that cover and protect the bud are

Accepted Answer

The outermost ring of floral structures that cover and protect the bud are sepals.

Question 8

The answer of Angiosperms have two separate gametophytes because
...

Question 9

The microspore develops into a

Accepted Answer

The microspore develops into a male gametophyte, which contains the pollen grains.

Question 10

A flower

Accepted Answer

All of the choices characterize flowers. Flowers are the reproductive structures of angiosperms (flowering plants). They contain the sexual reproductive organs, including male stamens and female pistils, which sometimes are located within the same flower or on separate flowers on the same plant. A flower is composed of whorls of modified leaves, including sepals, petals, stamens, and pistils. The beauty of flowers serves to attract animal pollinators, such as bees, butterflies, birds, and bats, which transfer pollen from one flower to another, allowing for fertilization and reproduction.

Question 11

Which of the following stages occurs immediately after the development of the zygote?

Accepted Answer

The development of the proembryo occurs immediately after the formation of the zygote, marking the beginning of the embryonic development process.

Question 12

A moth-pollinated flower is likely to have

Accepted Answer

Moth-pollinated flowers typically have light or white colors to be visible at night, no distinct landing area since moths hover while feeding, and a strong sweet perfume to attract moths from a distance.

Question 13

Pollen grains are formed in _________ and ova are formed in ____________.

Accepted Answer

Pollen grains are formed in stamens and ova are formed in carpels.

Question 14

If you have picked a bouquet of anther-less flowers, you have picked

Accepted Answer

Anther-less flowers usually lack male reproductive structures, the anthers, which produce microspores that differentiate into male gametophytes. Therefore, if you picked anther-less flowers, you likely picked female reproductive structures, the pistils, which contain the ovules that produce the female gametophytes. The female gametophyte is retained within the body of the sporophyte plant until fertilization occurs.

Question 15

Which of these typically occur in both angiosperms and gymnosperms?

Accepted Answer

Both angiosperms and gymnosperms rely on wind pollination, where pollen is carried by the wind rather than animal pollinators. Option A is specific to gymnosperms, while option B and C are specific to angiosperms. Option E, animal pollination, is also common in angiosperms but not all gymnosperms rely on animal pollination.

Question 16

Which of the following methods is used by plants when they are undergoing asexual reproduction?

Accepted Answer

All the given options are methods used by plants for asexual reproduction. Stolons are above-ground lateral stems that grow along the ground, producing new clones at nodes. Rhizomes are underground stems which develop roots and have the ability to produce new shoots. Suckers are shoot suckers that develop from the root base of certain types of trees, producing genetically identical offspring.

Question 17

Identify the labeled parts of the flower: 
A) ________ F. ________
B) ________ G. ________
C) ________ H. ________
D) ________ I. ________
E) ________ J. ________

Accepted Answer

The answer of Identify the labeled parts of the flower:...

Question 18

The name monocot and eudicot are derived from the differences in the number of

Accepted Answer

Monocots have one cotyledon in their embryos, while eudicots have two cotyledons.

Question 19

What is the correct sequence for the development of a eudicot embryo?
A. Globular stage
B. Heart stage
C. Proembryo stage
D. Mature embryo
E. Zygote forms
F. Torpedo stage rev: 11_13_2013_QC_40197

Accepted Answer

This sequence represents the correct order of development for a eudicot embryo, starting with the formation of the zygote and ending with the mature embryo. The proembryo stage is characterized by the differentiation of the apical meristem and the formation of the cotyledons, followed by the globular stage where the embryo takes a spherical shape. The heart stage is characterized by the bending of the embryo and the formation of the cotyledonary and hypocotyl regions. The torpedo stage marks the elongation of the embryo and the differentiation of the shoot and root apical meristems. Finally, the mature embryo is formed and is ready to germinate.

Question 20

The anther and filament are parts of the

Accepted Answer

The anther and filament are both parts of the stamen, which is the male reproductive organ of a flower. The pistil is the female reproductive organ, the sepal protects the flower bud, the receptacle is the base of the flower where all parts are attached, and the petal is a modified leaf that attracts pollinators.
