# 1 is the
Correct Answer
D. Stigma
2.
#2 is the
Correct Answer
B. Style
Explanation
The correct answer is "style." The question is asking for the correct term out of the given options, which are "ovary," "style," "stigma," and "anther." Among these options, the style is the correct answer. The style is a part of the female reproductive organ in a flower, connecting the stigma to the ovary.
3.
#3 is the
Correct Answer
D. Ovary
Explanation
The correct answer is ovary. In plants, the ovary is the part of the flower that contains the ovules, which are the structures that develop into seeds after fertilization. The ovary is located at the base of the flower and is typically swollen and enlarged. It plays a crucial role in reproduction as it protects and nourishes the developing seeds.
4.
#4 is the
Correct Answer
A. Ovule
Explanation
The correct answer is "ovule" because an ovule is a structure found in the pistil of a flower. It is the part of the flower that contains the female reproductive cells, which eventually develop into seeds after fertilization. The other options, such as receptacle, sepal, and petal, are not directly related to the female reproductive structure of a flower.
5.
#1 - #4 make up the
Correct Answer
F. Can be called either pistil or carpel
Explanation
The correct answer is "can be called either pistil or carpel." In botany, the pistil and carpel are two terms used to describe the female reproductive organ of a flower. The pistil is the collective term for all the female parts of a flower, including the stigma, style, and ovary. The carpel, on the other hand, refers specifically to the ovary and its associated structures. Since the pistil includes the carpel, it is correct to say that the female reproductive organ can be called either pistil or carpel.
6.
#6 is called the
Correct Answer
C. Anther
Explanation
The correct answer is "anther." The anther is the part of a flower's stamen that produces and holds the pollen. It is typically located at the top of the filament, which is the stalk-like structure that supports the anther. The sepal is the outermost part of the flower that protects the bud, while the stamen is the male reproductive organ of the flower. Therefore, the anther is the most appropriate answer as it specifically refers to the structure responsible for pollen production.
7.
#7 is called the
Correct Answer
C. Filament
Explanation
The correct answer is "filament" because the filament is the part of the stamen that supports the anther, which is where the pollen is produced. The anther and filament together make up the stamen, which is the male reproductive organ of a flower. Therefore, out of the given options, filament is the most appropriate term to describe #7.
8.
# 6 and #7
Correct Answer
B. Make up the stamen
Explanation
The correct answer is "make up the stamen." The stamen is the male reproductive part of a flower, consisting of the filament and anther. The filament supports the anther, which produces pollen. Therefore, options 1 and 3, which suggest that #6 and #7 produce the eggs or are the female parts of the flower, are incorrect. Option 4, "all of these," is also incorrect as it includes the incorrect options.
9.
#11 are the
Correct Answer
D. Sepal
Explanation
The given options are all parts of a flower. Petals are the colorful, leaf-like structures that surround the reproductive parts of the flower. Stamen are the male reproductive organs that produce pollen. Ovaries are the female reproductive organs that contain the ovules. Sepals are the outermost part of the flower that protect the developing bud. Among these options, sepal is the correct answer.
10.
#10 is the
Correct Answer
D. Receptacle
Explanation
The correct answer is "receptacle" because a receptacle refers to a container or holder that is used to store or hold something. In the context of the given options, a receptacle would be the most appropriate term to describe a container or holder. The other options, such as stem, base, and revolving nosepiece, do not accurately match the definition of a receptacle.
11.
Plants produce flowers to
Correct Answer
D. Reproduce
Explanation
Plants produce flowers to reproduce. Flowers contain the reproductive organs of plants, such as the male stamen and female pistil, which allow for the process of pollination and fertilization. This leads to the production of seeds and the development of new plants. Flowers attract pollinators like bees, butterflies, and birds, which help transfer pollen between flowers, facilitating the reproductive process. By producing flowers, plants ensure their survival and continuation through reproduction.

During the reproduction process in Angiosperms (flowering plants) where are the sperm cells prior to pollination?
Correct Answer
B. In the pollen
Explanation
Prior to pollination, the sperm cells in angiosperms are located in the pollen. Pollen grains contain the male gametes, including the sperm cells, which are responsible for fertilizing the female gametes within the ovules. Pollination occurs when the pollen is transferred from the anther (male reproductive organ) to the stigma (female reproductive organ) of the flower, allowing the sperm cells to reach the ovules and fertilize them. Therefore, the correct answer is "in the pollen."
13.
How can some seed plants reproduce without the use of an animal pollinator?
Correct Answer
D. Any of these might
Explanation
Some seed plants can reproduce without the use of an animal pollinator because they have the ability to self-pollinate. This means that they can transfer pollen from the male reproductive organs to the female reproductive organs within the same flower or between flowers on the same plant. Additionally, some seed plants use wind as a means of pollination, where the pollen is carried by air currents to reach the female reproductive organs. In certain cases, water can also serve as a pollinator for seed plants that live in aquatic environments. Therefore, any of these methods could be used by seed plants to reproduce without the need for an animal pollinator.
14.
What is the part of the female flower that the pollen sticks to in order to complete the pollination process?
Correct Answer
D. None of these
Explanation
The question asks about the part of the female flower that the pollen sticks to in order to complete the pollination process. However, none of the given options (sepal, anther, style) are correct. The correct answer is not provided, so it is not possible to determine the correct part of the female flower.
15.
Pollination leads to fertilization of the egg which leads to...
Correct Answer
B. Seeds being produced
Explanation
Pollination is the transfer of pollen from the male reproductive organ (stamen) to the female reproductive organ (pistil) of a flower. This transfer allows for fertilization to occur, where the sperm from the pollen combines with the egg in the ovary. Fertilization leads to the development of seeds, which contain the embryo of a new plant. Therefore, the correct answer is "seeds being produced".
