What is a rhizoid?
-
A drug
-
A root-like system in mosses
-
Shampoo that is all-natural
Correct Answer
A. A root-like system in mossesExplanation
A rhizoid is a root-like system found in mosses. Unlike true roots, rhizoids do not have vascular tissue and do not play a role in absorbing water or nutrients. Instead, they anchor the moss to the substrate and help with moisture absorption. Rhizoids are thread-like structures that extend from the base of the moss and penetrate into the soil or other surfaces, providing stability and support for the plant.Rate this question:

What are the parts of the female reproductive systems- the pistil- in a plant?
-
Stigms, stylus, uterus
-
Ovary, Style, Delta
-
Stigma, Style, Ovary
Correct Answer
A. Stigma, Style, OvaryExplanation
The pistil is the female reproductive organ in a plant. It consists of three parts: the stigma, style, and ovary. The stigma is the sticky structure at the top of the pistil that receives pollen. The style is a long tube-like structure that connects the stigma to the ovary. The ovary is the enlarged base of the pistil that contains the ovules, which eventually develop into seeds after fertilization. Therefore, the correct answer is "Stigma, Style, Ovary".Rate this question:

What is dormancy?
-
Time when plants grows a lot.
-
Time when plant stops growing.
-
Time when plant flowers.
Correct Answer
A. Time when plant stops growing.Explanation
Dormancy refers to the period when a plant ceases or slows down its growth. During this time, the plant's metabolic activities, including cell division and expansion, come to a halt. Dormancy is usually triggered by environmental factors such as cold temperatures, lack of water, or reduced sunlight. It is an adaptive mechanism that allows plants to conserve energy and survive unfavorable conditions.Rate this question:

What moves the water upwards in plants?
-
Phloem
-
Xylem
-
Water Throat
Correct Answer
A. XylemExplanation
Xylem is responsible for moving water upwards in plants. It is a complex tissue composed of specialized cells that form a network of interconnected tubes. These tubes transport water and dissolved minerals from the roots to the rest of the plant. Through a process called transpiration, water is pulled up through the xylem vessels due to the cohesion and adhesion properties of water molecules. This movement of water is essential for delivering nutrients and maintaining the plant's structure and function.Rate this question:

What is auxin?
-
Nothing.
-
Speeds up plant cell's growth
-
Help photosynthesis.
Correct Answer
A. Speeds up plant cell's growthExplanation
Auxin is a plant hormone that plays a crucial role in regulating plant growth and development. It is responsible for stimulating cell elongation and division, which ultimately leads to increased plant cell growth. By promoting the expansion of cells, auxin helps in various processes such as root and shoot growth, tropisms, and the formation of lateral roots. Therefore, the statement "Speeds up plant cell's growth" accurately describes the function of auxin in plants.Rate this question:

What are the two stages of a plant's life?
-
Sporophyte and Gametophyte
-
Lickophyte and Sporophyte
-
Baby and Adult
Correct Answer
A. Sporophyte and GametophyteExplanation
The two stages of a plant's life are sporophyte and gametophyte. The sporophyte stage is the diploid phase where the plant produces spores through meiosis. These spores then develop into the gametophyte stage, which is the haploid phase. In the gametophyte stage, the plant produces gametes through mitosis. Fertilization of the gametes leads to the formation of a new sporophyte, completing the plant's life cycle.Rate this question:

What are the parts of the male reproductive system- the stamen- in a plant?
-
Anther, filament
-
Sperm, bulb
-
Petal, antler
Correct Answer
A. Anther, filamentExplanation
The male reproductive system in a plant is composed of the stamen, which consists of two main parts: the anther and the filament. The anther is responsible for producing and releasing pollen, which contains the plant's male gametes. The filament is the stalk-like structure that supports the anther and positions it for optimal pollen dispersal. Therefore, the correct answer is "Anther, filament."Rate this question:
-
- 12.
In plants what moves food down from the leaves?
-
Phloem
-
Xylem
-
Food Throat
Correct Answer
A. PhloemExplanation
Phloem is the correct answer because it is the tissue responsible for transporting food, such as sugars and other organic compounds, from the leaves to other parts of the plant. This process is known as translocation and it occurs through specialized cells called sieve tube elements. Xylem, on the other hand, is responsible for transporting water and minerals from the roots to the leaves. "Food Throat" is not a valid term or concept in plant biology.Rate this question:

What does the name "gymnosperm" mean?
-
Naked plant
-
Naked seed
-
Naked Sperm
Correct Answer
A. Naked seedExplanation
The name "gymnosperm" means "naked seed". This refers to the fact that gymnosperms are a group of plants that have seeds that are not enclosed in a protective fruit or ovary. Instead, the seeds are exposed and not covered by any additional structure. This is in contrast to angiosperms, which are plants that have seeds enclosed within a fruit. The term "naked seed" accurately describes this characteristic of gymnosperms.Rate this question:
-
- 14.
Do leaves store food?
-
Yes.
-
No.
-
Waffles.
Correct Answer
A. Yes.Explanation
Leaves do store food through a process called photosynthesis. They contain chlorophyll, which helps convert sunlight, carbon dioxide, and water into glucose (a form of sugar) and oxygen. The glucose is then stored in the leaves as starch or transported to other parts of the plant for energy and growth. Therefore, leaves play a vital role in the storage and distribution of food within a plant.Rate this question:

What determines a flower's time of flowering?
-
Heat
-
Light/ Darkness
-
Water
Correct Answer
A. Light/ DarknessExplanation
Light and darkness play a crucial role in determining a flower's time of flowering. This is because plants have a natural response to the duration of daylight and darkness, known as photoperiodism. Different plants have different requirements for the length of light and darkness they need to initiate flowering. Some plants require shorter days or longer nights, while others require longer days or shorter nights. This response is controlled by specific proteins in the plant's cells that detect the duration of light and darkness. Therefore, light and darkness are key factors in regulating a flower's time of flowering.Rate this question:

How is a seed made?
-
Pollen fertilizes an egg in a stem.
-
Pollen fertilizes an egg in the pistil.
-
Pollen fertilizes an egg in the flower.
Correct Answer
A. Pollen fertilizes an egg in the pistil.Explanation
Seeds are made through the process of fertilization, where pollen from the male reproductive organ (stamen) fertilizes an egg in the female reproductive organ (pistil). The pistil contains the ovary, which holds the eggs, and the pollen travels through the pistil to reach the eggs and fertilize them. Therefore, the correct answer is "Pollen fertilizes an egg in the pistil."Rate this question:

What is the reproductive structure of a gymnnosperm?
-
Fruit
-
Leaf
-
Cone
Correct Answer
A. ConeExplanation
The reproductive structure of a gymnosperm is a cone. Gymnosperms are a group of plants that produce seeds without enclosing them in a fruit. Instead, they have cones that contain the reproductive structures, such as male and female cones. These cones are responsible for the production of pollen and seeds, making them the key reproductive structure of gymnosperms.Rate this question:

In what stage are egg and sperm cells produced in a plant?
-
Gametophyte
-
Sporophyte
-
Lickophyte
Correct Answer
A. GametophyteExplanation
The correct answer is Gametophyte because in plants, the gametophyte stage is where egg and sperm cells are produced. The gametophyte is the haploid stage of the plant's life cycle, and it is responsible for producing the gametes through the process of mitosis. This stage is characterized by the production of male and female gametophytes, which eventually give rise to the sperm and egg cells respectively. The gametes then fuse during fertilization to form a diploid zygote, which develops into the sporophyte stage of the plant's life cycle.Rate this question:

What happens when the zygote is formed?
-
Pollen falls on the anther.
-
Pollen falls on the stigma.
-
Pollen falls on the style.
Correct Answer
A. Pollen falls on the stigma.Explanation
When the zygote is formed, it means that fertilization has taken place between the male and female gametes. In plants, this occurs when pollen, which contains the male gametes, falls on the stigma, which is part of the female reproductive structure. The pollen then germinates and grows a pollen tube through the style, allowing the male gametes to reach the ovary and fertilize the egg, resulting in the formation of a zygote. Therefore, the correct answer is "Pollen falls on the stigma."Rate this question:
-
- 26.
Does a seed need for germination?
-
Air
-
Water
-
Soil
Correct Answer
A. WaterExplanation
Water is essential for seed germination because it helps to soften the seed coat and activate enzymes that break down stored food for growth. Without water, the seed would remain dormant and unable to sprout. Additionally, water provides the necessary medium for the movement of nutrients and minerals into the seed, which are essential for its growth and development. Therefore, water is a crucial requirement for seed germination.Rate this question:
