  • 2. 

    The female part of a flower is called the ___________________.

    • Stamen

    • Root

    • Pistil

    • Egg

    Correct Answer
    A. Pistil
    Explanation
    The female part of a flower is called the pistil. The pistil is the reproductive organ of a flower that consists of three main parts: the stigma, the style, and the ovary. The stigma is the sticky surface where pollen is collected, the style is the tube connecting the stigma to the ovary, and the ovary contains the ovules, which develop into seeds after fertilization. The pistil plays a crucial role in the reproduction of flowering plants by receiving pollen and facilitating fertilization.

    The tiny offspring inside a seed that can grow into a new plant is called a(n) _____________.

    • Pistil

    • Embryo

    • Egg

    • Leaf

    Correct Answer
    A. Embryo
    Explanation
    An embryo is the tiny offspring inside a seed that has the potential to grow into a new plant. It contains the genetic information necessary for the development of the plant and is protected by the seed coat. The embryo is the earliest stage of growth in a plant's life cycle and is vital for the continuation of the species.

    Rate this question:

  • 4. 

    Angiosperms produce reproductive organs called flowers.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    Angiosperms are a group of plants that produce flowers as their reproductive organs. Flowers are the structures where the production of seeds takes place. They contain the male and female reproductive parts, such as stamens and pistils, which facilitate pollination and fertilization. This characteristic is unique to angiosperms and distinguishes them from other groups of plants, such as gymnosperms. Therefore, the statement "Angiosperms produce reproductive organs called flowers" is true.

    Rate this question:

  • 5. 

    After pollination, sperm cells from pollen move down the style of the pistil to the ovary.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    After pollination, the sperm cells from the pollen need to reach the ovary in order for fertilization to occur. This is achieved by the sperm cells moving down the style of the pistil, a long tube-like structure that connects the stigma (where the pollen lands) to the ovary. Once the sperm cells reach the ovary, they can fertilize the egg cells and initiate the development of seeds. Therefore, the statement is true.

  • 6. 

    I am the tough, outer covering on a seed.What am I?

    • Seed coat

    • Shell

    • Shield

    • Offspring

    Correct Answer
    A. Seed coat
    Explanation
    The tough, outer covering on a seed is called the seed coat. It protects the delicate embryo inside the seed from damage, dehydration, and pathogens. The seed coat also helps in seed dispersal by providing resistance to environmental conditions and predators.

    Rate this question:

  • 7. 

    The pistil is made up of a stigma, a style, and a(n) _________________(which contains the egg cells).

    • Flower

    • Egg

    • Ovary

    • Stamen

    Correct Answer
    A. Ovary
    Explanation
    The pistil is made up of a stigma, a style, and an ovary. The ovary is the part of the pistil that contains the egg cells.

    Rate this question:

  • 8. 

    In addition to the embryo, a seed contains  a food supply called the cotyledon.

    • True

    • False

    Correct Answer
    A. True
    Explanation
    A seed contains a food supply called the cotyledon, which provides nutrients to the embryo during germination. This food supply is essential for the initial growth and development of the plant until it can produce its own food through photosynthesis. Therefore, the statement that a seed contains a food supply called the cotyledon is true.

    Rate this question:

  • 9. 

    During the asexual phase, moss plants form capsules that contain _____________.

    • Eggs

    • Sugar

    • Leaves

    • Spores

    Correct Answer
    A. Spores
    Explanation
    During the asexual phase, moss plants form capsules that contain spores. Spores are reproductive structures that are produced by moss plants as a means of reproduction. These spores are released from the capsules and can develop into new moss plants under favorable conditions. This method of reproduction allows moss plants to spread and colonize new areas.

    Rate this question:

  • 10. 

    The development of a seed into a new plant is called ______________. .

    • Germination

    • Fertilization

    • Growing

    • Stamen

    Correct Answer
    A. Germination
    Explanation
    Germination refers to the process by which a seed grows into a new plant. It involves the activation of the seed, followed by the emergence of the radicle (embryonic root) and the subsequent growth of the shoot. This process is triggered by favorable environmental conditions such as moisture, warmth, and oxygen. During germination, the seed absorbs water, which activates enzymes that break down stored nutrients, providing energy for growth. Eventually, the seed coat is shed, and the seedling continues to grow into a mature plant.

  • 11. 

    Plant life cycles have two alternating phases, one sexual and one asexual. This type of life cycle is called _______________________. .

    • Multiple generation

    • Alternative generation

    • Fixed generation

    • Plant generation

    Correct Answer
    A. Alternative generation
    Explanation
    The correct answer is "alternative generation" because it refers to the two alternating phases in the plant life cycle, one sexual and one asexual. This term accurately describes the pattern of reproduction in plants, where they switch between sexual reproduction through the production of seeds and asexual reproduction through the production of spores or vegetative propagation.

    During the sexual phase, moss spores grow into plants with male and female branches. Rainwater carries sperm to egg cells, and _______________ occurs.

    • Growing

    • Sterilizaton

    • Fertilization

    • Eggs

    Correct Answer
    A. Fertilization
    Explanation
    During the sexual phase of moss, the spores develop into plants with both male and female branches. Rainwater plays a crucial role in this process by carrying the sperm to the egg cells. This fusion of sperm and egg cells is known as fertilization.

    In gymnosperms and angiosperms, the asexual phase is much reduced, and the _________________is the dominant part of the life cycle.

    • Asexual phase

    • Sexual phase

    • Growth phase

    • Cycle phase

    Correct Answer
    A. Sexual phase
    Explanation
    In gymnosperms and angiosperms, the asexual phase is much reduced, indicating that it plays a minor role in the life cycle. On the other hand, the sexual phase is the dominant part of the life cycle. This means that the reproduction and genetic exchange through sexual reproduction are the key processes that occur in these plants, leading to the production of seeds and the continuation of the species.

  • 14. 

    When pollen from the male cones reaches the female cones,_______________ occurs.

    • Germination

    • Occuption

    • Pollination

    • Sanitation

    Correct Answer
    A. Pollination
    Explanation
    Pollination is the process in which pollen from the male cones is transferred to the female cones. This transfer of pollen allows for fertilization to occur, resulting in the development of seeds. Germination refers to the process of a seed sprouting and growing into a new plant, which is not directly related to the transfer of pollen. Occuption and sanitation are unrelated terms and do not apply to the given context.

    Rate this question:

  • 15. 

    At the top of the filament is the __________,where pollen is produced.

    • Case

    • Flower

    • Anther

    • Pollen

    Correct Answer
    A. Anther
    Explanation
    The anther is the correct answer because it is the part of the filament where pollen is produced.

    Rate this question:

  • 16. 

    Cone-bearing plants, such as pines and firs, are called ___________ .

    • Red woods

    • Mosses

    • Pines

    • Conifers

    Correct Answer
    A. Conifers
    Explanation
    Cone-bearing plants, such as pines and firs, are called conifers because they produce cones as their reproductive structures. These cones contain the seeds of the plant and are typically woody and durable. Conifers are well-adapted to cold climates and are often evergreen, meaning they retain their leaves or needles year-round. They are also known for their tall, straight trunks and are commonly used for lumber.

    Rate this question:

  • 17. 

    The ovary enlarges to become a(n) ________________as the seeds develop.

    • Flower

    • Fruit

    • Grape

    • Leaf

    Correct Answer
    A. Fruit
    Explanation
    As the seeds develop, the ovary enlarges and transforms into a fruit. This is because the ovary is the part of the flower that contains the ovules, which develop into seeds once fertilized. The ovary undergoes changes in size, texture, and structure to protect and nourish the developing seeds. The fruit serves as a means of dispersal for the seeds, often attracting animals to eat the fruit and then disperse the seeds through their droppings.

    Rate this question:

  • 18. 

    I contain a flowering plant's sperm cells,I am the stamen.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The given statement is false. The stamen is not a structure that contains a flowering plant's sperm cells. The stamen is actually the male reproductive part of a flower, consisting of the anther and filament. The anther is the part that produces and holds the pollen, which contains the sperm cells. Therefore, the correct answer is false.

    Rate this question:

  • 19. 

    Seeds with two cotyledons are called monocot.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    The statement "Seeds with two cotyledons are called monocot" is false. Seeds with two cotyledons are actually called dicots, not monocots. Monocots have only one cotyledon.

    Rate this question:

  • 20. 

    Seeds with one cotyledon are called dicot.

    • True

    • False

    Correct Answer
    A. False
    Explanation
    Seeds with one cotyledon are actually called monocot, not dicot. This is because monocotyledonous plants have seeds with a single embryonic leaf, while dicotyledonous plants have seeds with two embryonic leaves. Therefore, the correct answer is False.
