Botany

A:

Examples of aquatic plants include the water lily, Victorian water lily, frog-bit, floating heart, pondweed, water-shield, yellow pond-lily, cape-pondweed and water-chestnut. Also referred to as aquatic macrophytes or hydrophytes, aquatic plants are plants that are adapted to live in water or aquatic environment.

  • What are the characteristics of plants?

    Q: What are the characteristics of plants?

    A: Plants are eukaryotic, meaning their cells have a nucleus. They form tissues, have multiple cells and create food through photosynthesis, which is the process of turning sunlight into energy.

  • What is the reproductive part of a plant called?

    Q: What is the reproductive part of a plant called?

    A: A plant's flower contains its reproductive components. The plant male reproductive organs are called stamens, and the plant female reproductive organs are called carpels, or a pistil.

  • How does chlorophyll make a leaf look green?

    Q: How does chlorophyll make a leaf look green?

    A: Chlorophyll, a type of pigment, makes leaves look green because it reflects light that falls in the green part of the visible light spectrum while absorbing other wavelengths of light. Chlorophyll molecules are classified as “photoreceptors,” meaning that they capture light energy and transfer it to molecules that transform it into chemical energy. There are three main types of chlorophyll that work together to collect as much energy as possible.

  • What is the function of a plant's stem?

    Q: What is the function of a plant's stem?

    A: A plant’s stem serves as the support structure for its above ground components and as a conduit through which water and nutrients can travel. When a stem is green due to the presence of chlorophyll, it also produces food. In some plant species, the stem stores energy or food for future use.

  • How are plants adapted to live in dry conditions?

    Q: How are plants adapted to live in dry conditions?

    A: Plants adapt to dry conditions in a variety of ways, but many respond to dry conditions by storing large quantities of water, which can be used in times of need. For example, cactuses store water in their trunks and stems, while aloe plants store water in their leaves. Additionally, plants that live in dry areas often evolve thick outer cuticles that can help retard the rate of water loss.

  • How many chromosomes do potatoes have?

    Q: How many chromosomes do potatoes have?

    A: Potatoes have 48 chromosomes that are arranged into 24 pairs. The number of chromosomes in living organisms, including plants, flowers and vegetables, varies widely. Some, such as the garden onion, have only 16 chromosomes, while other species like ferns, have over 100 pairs of chromosomes.

  • What is the scientific classification of mushrooms?

    Q: What is the scientific classification of mushrooms?

    A: All mushrooms belong to the Fungi kingdom, however their phylum, class, family, and genus vary according to the mushroom type. Oyster mushrooms, meadow mushrooms and button mushrooms all have different scientific classifications.

  • What are characteristics of the kingdom Plantae?

    Q: What are characteristics of the kingdom Plantae?

    A: Plantae is a large and diverse kingdom which includes all of the trees, grasses, ferns and mosses in the world. All plants are eukaryotes, with nucleated cells and organelles such as mitochondria and chloroplasts. Their cells have distinct cellulose walls that other organisms lack. All plants are descended from a common ancestor.

  • Why do sunflowers face the sun?

    Q: Why do sunflowers face the sun?

    A: No one knows why sunflowers track the sun, but scientists suspect that it may enhance the flower’s chances for pollination, increase the amount of heat the flower absorbs or accelerate the maturation of the sunflower seeds. Sunflowers achieve their movement through the differential growth rate of the cells in the stem. When the cells on the right side of the plant grow quickly, the flower head tilts the opposite direction.

  • 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.

  • 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.

  • What do all plants have in common?

    Q: What do all plants have in common?

    A: All true plants are multicellular eukaryotes and members of the Kingdom Plantae. All plants extract a majority of their energy autotrophically from sunlight through a process known as photosynthesis.

  • 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.

  • Wlhat is the function of the stamen?

    Q: Wlhat is the function of the stamen?

    A: The stamen is the male reproductive organ in flowering plants. It consists of an anther, which is the site where pollen develops, and in most species, a filament.

  • 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.

  • Are orchids poisonous?

    Q: Are orchids poisonous?

    A: Orchids are not poisonous to humans, dogs, cats or horses. The orchid is officially known as the Phalaenopsis orchid and also goes by the names of moth orchid and moon orchid. While orchids are considered a safe and nontoxic plant, it is possible for reactions to still occur if a person is particularly sensitive.

  • What is the difference between monocot and dicot stems?

    Q: What is the difference between monocot and dicot stems?

    A: Dicot stems have a circular arrangement of vascular tissues, whereas the stems of monocots have vascular-tissue bundles scattered throughout. In monocots the vascular bundles also tend to be toward the outside of the stem. Dicot vascular tissue forms a cylinder near the center of the stem.

  • What are the five stages of seed germination?

    Q: What are the five stages of seed germination?

    A: Seed germination begins when the first root breaks through the seed wall and ends when the first pair of true leaves begin the process of photosynthesis. The three stages in-between are when the primary root, which is called the radicle, develops root hairs, the first young shoot rises emerges from the soil and the first pair of true leaves form to begin to manufacture food for the plant.

  • What is the economic importance of gymnosperms?

    Q: What is the economic importance of gymnosperms?

    A: Gymnosperms are widely used in construction, furniture-building, paper-making and urban planning, as well as providing important solvents for industrial and home use, cleaning agents, and food. Gymnosperms are plants that do not flower and instead produce bare seeds or cones, as with the familiar pine tree.

  • How do plants get nitrogen?

    Q: How do plants get nitrogen?

    A: Plants obtain nitrogen through the Nitrogen cycle. Air consists of 78 percent nitrogen, which is in the form of nitrous oxides. Rain water dissolves these oxides and nitrogen enters the soil, which plants then absorb by drawing in water through the roots.
