Botany

A:

It has been proven that coffee and coffee grounds make plants grow faster. However, no one is certain whether the growth has anything to do with caffeine or if the other ingredients found in coffee are responsible.

  • What Does the Root of a Plant Do?

    Q: What Does the Root of a Plant Do?

    A: The main function of a plant root is to absorb water and minerals from the soil for the plant to use. Roots also anchor plants into the ground, offering them support and keeping them from washing or blowing away. In some plants, such as carrots, roots store carbohydrates that the plant has made through photosynthesis for later use.

  • Where Is Starch Stored Within Plants?

    Q: Where Is Starch Stored Within Plants?

    A: Starch is stored primarily in the tubers of plants, according to Orthomolecular.org. It also can be found in the seeds, fruits and roots in the form of grains of varying size and shape.

  • What Is the Function of a Flower's Style?

    Q: What Is the Function of a Flower's Style?

    A: In plants, the style is the long, slender stalk that connects the stigma to the ovary. The stigma is where the pollen is deposited, and the ovary is at the bottom of the style and houses the plant's ovules, which contain the egg cells. The function of the style is to check compatibility and judge whether the pollen that lands on the flower can fertilize the plant.

  • What Is the Difference Between Pollination and Fertilization?

    Q: What Is the Difference Between Pollination and Fertilization?

    A: Pollination is the process whereby pollen grains move from the anther to the stigma on a flower’s style, while fertilization is the fusion of the male gametes and female egg cells to form a new plant seed. Pollination precedes fertilization and depends on such media as wind, water and insects. Pollination takes place externally, while fertilization occurs in the inside of the flower and does not depend on external vectors.

  • 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 Is the Importance of Botany?

    Q: What Is the Importance of Botany?

    A: Botany is important primarily because it is the scientific study of plants, which are in turn used in many aspects of human life. Botanists study plants of all kinds and apply their knowledge of characteristics and traits of crops, plants and flowers to influence the fields of medicine, science and cosmetics among others. Plants support basic daily functions of human life by providing food and nutrition, supplementing medicines and cosmetic products and serving as important ingredients in a variety of medicines.

  • Why Do We Need Plants?

    Q: Why Do We Need Plants?

    A: Plants are necessary because they are a primary food source and provide the oxygen that is vital to animals' and humans' existence. A majority of the calories that people consume comes from plants, and most meat comes from animals that eat plants. Plants are at the bottom of the food chain, and animals could not survive without them. Plants also release the oxygen that humans and animals breathe.

  • What Is an Example of a Non-Green Plant?

    Q: What Is an Example of a Non-Green Plant?

    A: One common example of a non-green plant is Monotropa uniflora, or Indian Pipe. This completely white member of the blueberry family gets its color from a lack of chlorophyll, or the molecule that synthesizes sugar from sunlight and carbon dioxide.

  • What Is Photosynthesis?

    Q: What Is Photosynthesis?

    A: Photosynthesis is the process by which green plants manufacture their own food. The process takes place in small structures within the plant’s cells called chloroplasts. Photosynthesis evolved about 3 billion years ago, yet it remains the most important method for harvesting the sun’s energy on the planet.

  • What Are the Products of Photosynthesis?

    Q: What Are the Products of Photosynthesis?

    A: The products of photosynthesis are glucose and oxygen. Photosynthesis takes in carbon dioxide and water and combine them in the presence of energy from the sun to make food for the organism.

  • 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 Releases Oxygen in Photosynthesis?

    Q: What Releases Oxygen in Photosynthesis?

    A: In oxygenic photosynthesis, cyanobacteria and the chloroplasts of plants and algae turn carbon dioxide, water and photons into carbohydrates and free oxygen. Only some of this oxygen is used by the organism; the rest is released into the atmosphere.

  • What Are the Advantages of Seeds Over Spores?

    Q: What Are the Advantages of Seeds Over Spores?

    A: Seeds, when compared to spores, have distinct advantages due to their hard outer shells and internal structures called endosperms, which provide essential nutrients for enclosed seedlings. Seeds are found only in flowering plants and gymnosperms. They contain embryos deep within their centers, which are surrounded by a sack of nutrients and minerals enclosed by a tough protective outer shell that protects the growing seed from predation and life-threatening exposure to the elements.

  • What Is the Function of a Flower?

    Q: What Is the Function of a Flower?

    A: The purpose of a flower is to attract pollinators to a plant to aid in fertilization so that the plant creates seeds. Bright colors, strong scents and sweet nectar all work together to attract birds, bees and other insects to move pollen from one flower to another. After pollination occurs, the flower develops seeds.

  • 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.
