Ovules are the parts of flowers that develop into seeds. Ovules exist in female plants and flowers, and reside in the ovaries. They form the reproductive system of plants, along with many other organs, enabling the growth and development of new offspring.Continue Reading
The work of ovules begins with pollination. Pollination occurs when grains land on the flowers of receptive species. These grains then stimulate the growth of pollen tubes, which connect with ovules in the ovaries. This connection facilitates the passage of male gametes into the ovaries. There, male gametes fertilize eggs, and the process of fertilization completes. Upon fertilization, seeds develop from the ovules and eventually turn into fruit.
Ovules exist in many types of plants, flowers and trees, but vary in location and shape depending on the species. In gymnosperms, which include conifers and cone-bearing relatives, ovules exist on the scales of cones, exposed to the environment. In angiosperms, or flowering plants, ovules attach to stalk bases and derive protection from surrounding outer shells. In addition to affording seeds protection with outer shells, ovules support growth and provide nutrition. One or two external seed coats supply germinating seeds with food, along with a layer of food tissue. Ovules in some plants stand vertically, while others lean sideways or backwards, which helps identify the plant species.Learn more about Botany
Plants disperse their seeds with the help of wind and water, animals and force from the plant itself when the seed pod bursts open. It is important that seeds move away from the mother plant so that the plants do not become overcrowded.Full Answer >
A seed plant is a plant that reproduces by generating and dispersing seeds. Gymnosperms, or flowering plants, and angiosperms, or non-flowering plants, are common names given to the two common categories of seed plants.Full Answer >
Celery plants are composed of roots, leaf stalks, leaves, flowers and seeds. The leaf stalk, also called the petiole, contains collenchyma tissue, xylem tissue and phloem tissue. Collenchyma tissue is made up of elongated cells full of water that provide a crispy texture and help support the plant. Collenchyma tissue is also part of the structure of the flowers and leaves.Full Answer >
A locust tree can be identified by its bark, leaves, flowers and seeds, which varies depending on the type of locust. It can also be identified by its habit, which can be a pyramidal, spreading, round or vaselike shape. The area where the tree grows can also help in its identification. Locust trees are native to the eastern part of the United States.Full Answer >
