What are some examples of gymnosperms and angiosperms?

Examples are pines, cedars, spruces and firs. Some gymnosperms do drop their leaves - ginkgo, dawn redwood, and baldcypress, to name a few. --Angiosperms are a taxonomic class of plants in which the mature seed is surrounded by the ovule (think of an apple). This group is often referred to as hardwoods.
A.

What is difference between gymnosperms and angiosperms?

The key difference between angiosperms and gymnosperms is how their seeds are developed. The seeds of angiosperms develop in the ovaries of flowers and are surrounded by a protective fruit. Gymnosperm seeds are usually formed in unisexual cones, known as strobili, and the plants lack fruits and flowers.
  • What structure in gymnosperms and angiosperms becomes the seed?

    As in gymnosperms, the ovule becomes a seed, encasing the embryo and endosperm in a seed coat. But unlike gymnosperms, in angiosperms the ovary containing the ovules develops into a fruit after fertilization.
  • Do angiosperms produce flowers or fruit?

    Like gymnosperms, angiosperms are seed-producing plants. However, they are distinguished from gymnosperms by characteristics including flowers, endosperm within the seeds, and the production of fruits that contain the seeds.
  • Are gymnosperms and angiosperms vascular or nonvascular?

    Gymnosperms were the first plants with seeds. They are vascular plants and do not produce flowers. However, the seed is beneficial because it provides protection and food for the plant embryo. Examples of gymnosperms include conifers - or evergreens - and ginkgoes.
B.

How does pollination in gymnosperms and angiosperms differ?

Pollination and Fertilization. Pollination is the transfer of pollen to the female organs of seed plants. In flowering plants (angiosperms, or "covered seeds"), immature seeds (ovules) are located within carpels. Gymnosperms have simpler pollination as all transmit their pollen by wind.
  • How does pollination occur in angiosperms?

    Seeds are made at the base of the pistil, in the ovule. To be pollinated, pollen must be moved from a stamen to the stigma. When pollen from a plant's stamen is transferred to that same plant's stigma, it is called self-pollination. Pollen from a rose or an apple tree would not work.
  • Why do plants have a flower?

    Pollen is a collection of male reproductive cells that will fertilize ovules to produce seeds. When the flower blooms, male pollen cells are scattered by insects or by the wind. Some kinds of plants produce only complete flowers. Other plants produce both male and female incomplete flowers on the same plant.
  • What are the four main types of gymnosperms?

    acid (DNA) has shown that the gymnosperms consist of four major, related groups: conifers, cycads, ginkgo, and gnetophytes.
    • Conifers. With approximately 588 living species, this is the most diverse and by far the most ecologically and economically important gymnosperm group.
    • Cycads.
    • Ginkgo.
    • Gnetophytes.
    • Bibliography.
C.

What are produced by angiosperms but not by gymnosperms?

The ovules in angiosperms are encased in an ovary, not exposed on the sporophylls of a strobilus, as they are in gymnosperms. Angiosperm means "covered seed". The ovules develop into seeds, and the wall of the ovary forms a fruit to contain those seeds. Fruits attract animals to disperse the seeds.
  • What is the life cycle of an angiosperm?

    The adult, or sporophyte, phase is the main phase of an angiosperm's life cycle. As with gymnosperms, angiosperms are heterosporous. Therefore, they generate microspores, which will produce pollen grains as the male gametophytes, and megaspores, which will form an ovule that contains female gametophytes.
  • Is a corn plant an angiosperm?

    The angiosperms are divided into two classes: the monocots and the dicots. (Not all dicots' seed leaves emerge during germination; for example, peas are dicots, but the pea cotyledons remain underground.) Corn is an example of a monocot. Corn seed has one cotyledon and can't readily be split.
  • Do all gymnosperms have motile sperm?

    Two main modes of fertilization are found in gymnosperms. Cycads and Ginkgo have motile sperm that swim directly to the egg inside the ovule, whereas conifers and gnetophytes have sperm with no flagella that are moved along a pollen tube to the egg. More than one embryo is usually initiated in each gymnosperm seed.
