Botany

A:

The cactus is a plant that flowers, and the blooms generate fruit that bears seeds; it is the seeds that end up leading to new cactus plants. Bats provide the pollination for some species of cactus, and the flowers bloom in the spring each year. It is also possible to grow a cactus from broken fragments of an existing cactus, but the new plant is genetically identical.

  • 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.

  • How are fungi and plants similar?

    Q: How are fungi and plants similar?

    A: Plants and fungi are both eukaryotic organisms whose cells are buffered by cellulose walls. Like plants, some fungi can be used as food and medicine, and they are alike in their relative lack of mobility.

  • What is the function of the lower epidermis?

    Q: What is the function of the lower epidermis?

    A: The lower epidermis contains stomata cells that help prevent water loss and regulate the exchange of gases such as oxygen and carbon dioxide, enabling plants to survive. Other cells in the lower epidermis include a waxy cuticle to protect underlying layers, according to Education Portal. Transparency in epidermal cells allows sunlight to pass through to chloroplasts, which are involved in photosynthesis.

  • 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 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.

  • 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.

  • 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 eats moss?

    Q: What eats moss?

    A: Low-altitude pikas survive by eating moss, but very few other animals can do so because moss is a very poor-quality food, says National Geographic. Fairfax County Public Schools reports that a few small mites and crustaceans eat moss, but most small animals use it as shelter material rather than food.

  • 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 transpiration pull theory?

    Q: What is transpiration pull theory?

    A: Transpiration pull theory is the proposed mechanism by which trees draw water through their roots. Transpiration occurs when the leaves of a tree allow water to exit into the air by means of tiny holes called stomata. When the water exits the leaves, the combination of capillary action, cohesion and adhesion draws more water up through the plant's roots to replace the released water.

  • How do plants absorb carbon dioxide?

    Q: How do plants absorb carbon dioxide?

    A: Plants absorb carbon dioxide from the air, through the stomata present in their leaves. Stomata are small holes that are present in the underside of leaves.

    Q: In which part of the chloroplast does each stage occur?

    A: Photosynthesis takes place in the cell's chloroplast in two stages: the light stage and the dark stage. Each stage occurs in a different part of the chloroplast.

  • How often do oak trees produce acorns?

    Q: How often do oak trees produce acorns?

    A: Oak trees produce acorns once per year. The number of acorns produced can vary from a handful one year to a large amount on what is called a "mast year." A theory that explains the excessive fruit production is predator saturation, when the tree attempts to produce more fruit than can be eaten by predators.

  • What are the two main functions of roots?

    Q: What are the two main functions of roots?

    A: The two main functions of roots are to deliver water and nutrients to the plant or tree and provide an anchor that keeps the plant or tree in the soil. Roots are generally the first part of any plant that emerges during germination.

  • What is the female part of a flower called?

    Q: What is the female part of a flower called?

    A: The female part of the flower is called the carpel or pistil. The pistil is comprised of three parts: the stigma, style and ovary. Flowers can have male parts, female parts or both; those with only female parts are called carpellate or pistillate flowers.

  • 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.

  • Can plants recognize their siblings?

    Q: Can plants recognize their siblings?

    A: Some people think if you've seen one mustard plant, you've seen them all, but that isn't true. If plants could talk, they would tell you that they are able to recognize their siblings, or seeds that have grown from the same mother plant. Additionally, the plants will show preferential treatment toward its kin.
