  • What is the function of flower petals?

    Q: What is the function of flower petals?

    A: The main function of flower petals is to attract pollinators such as butterflies, bees and bats. Flower petals typically have bright and vivid colors which assist in pollination by drawing the attention of insects, birds and animals. Some petals have markings, such as spots and stripes, to help pollinators find the pollen in the flower.

  • What percent of the sun's energy do plants use?

    Q: What percent of the sun's energy do plants use?

    A: For photosynthesis, plants use approximately 0.023 percent of sunlight energy. This is a very small percentage that plants need to make food when compared to the water cycle’s use of solar energy, which is 23 percent.

  • When does photosynthesis occur?

    Q: When does photosynthesis occur?

    A: Photosynthesis, the process by which plants convert the sun's energy to glucose, takes place during daylight hours when the plant's leaves are exposed to sunlight. This process only occurs in green plants and in some protist species. Carbon dioxide and water must also be present in order for photosynthesis to occur.

  • Where does photosynthesis take place in a cactus?

    Q: Where does photosynthesis take place in a cactus?

    A: While different cactuses may have specialized photosynthetic techniques, in general, photosynthesis occurs in a cactus' stem or trunk. The concept of photosynthesis in a cactus or succulent plant may seem strange considering that most of them do not have obvious leaves like many other plants, but their stems or trunks serve the same photosynthetic function as some other plants' leaves.

  • What are the four things needed for photosynthesis?

    Q: What are the four things needed for photosynthesis?

    A: Photosynthesis can only occur when a plant has access to water, carbon dioxide, sunlight and chlorophyll. Plant cells naturally produce chlorophyll, and they draw carbon dioxide directly from the air. Water and sunlight must be acquired from external sources.

  • How does climate affect the type of biome found in an area?

    Q: How does climate affect the type of biome found in an area?

    A: Climate affects the temperature, amount of water and amount of sunlight in an area. These factors affect the look of the land, as well as what types of plants and animals can survive in the biome. When the climate changes drastically, it can have seriously negative impacts on the biome.

  • What happens during the process of germination?

    Q: What happens during the process of germination?

    A: Germination takes place in three steps or stages and takes the young seed from a dormant state to the very beginning stage of growing as a seedling. Germination takes place in plants, flowers and trees: this process is to members of the plant family what metamorphosis is to insects such as moths and butterflies. The process requires several critical ingredients to begin, including water, sunlight and nutrients.

  • Can plants call for help?

    Q: Can plants call for help?

    A: The neighbor's apple tree can't exactly dial 911 if its branches are pruned too short, but some plants can indicate when they are "under attack" or in distress by releasing a chemical compound. This chemical release lets other creatures and similar plants know if an insect or other unwanted intruder is attacking.

    Q: What is the difference between an aspen and a birch tree?

    A: Birch trees and aspen trees have a similar appearance, but possess significant differences, specifically in their leaves, buds, bark and abilities to tolerate extreme climates. Additionally, while aspen trees are found across the country, birch trees are primarily found only in the eastern United States and areas of Canada, according to Garden Guides.

  • How does moss reproduce?

    Q: How does moss reproduce?

    A: Moss reproduces both sexually and asexually. For sexual reproduction, plants produce a male and female structure, often on different plants, and the sperm swims toward the eggs to accomplish fertilization. In the case of asexual reproduction, any time part of the stem or even just a leaf breaks off, the bits regenerate to create a new moss plant.

  • Who discovered plastids?

    Q: Who discovered plastids?

    A: The term "plastid" was coined by German biologist Ernst Haeckel in a paper he presented in 1866, but the term was too vague. In 1883, fellow German Andreas Schimper was the first to provide a clear definition to "plastid" and note the relationship between different types.

  • What are the two stages of photosynthesis called?

    Q: What are the two stages of photosynthesis called?

    A: Photosynthesis takes place in two stages: the light reactions and the dark reactions. The light reactions take their name because they require the presence of direct light, while the dark reactions do not have the same proviso. Light reactions occur in the thylakoid stacks in the grana for the most part, while dark reactions do not, although they also most frequently happen during the daytime.
