Textbook Question
Chapter 10, Problem 1AC
Many plants car. reproduce sexually or asexually. Strawberries, for example, can reproduce asexually by sending out horizontal stems cabled runners that root and form new plants, or they can reproduce sexually by flowering and producing fruit and seeds. Describe some advantages and disadvantages of each type of reproduction in wild plants. Include in your discussion the important aspects of the environments in which runners and seeds are likely to find themselves.

Students have asked these similar questions
An alternation of generation life cycle in plants is advantageous because:
each generation is morphologically similar.
it protects reproductive structures.
the gametes fuse in open water.
it is haploid-dominant.
In the Kotukutuku plant, Fuchsia excortiata, why do pollinated flowers remain attached to the plant for several days
after pollination occurs and nectar is no longer produced
Size of flower and pollination
Annual versus perennial reproduction
Time and expense to grow the pollen tube outweighs the cost of maintaining the flower on the tree
Size of flower and number of flowers on inflorescence
what are the flaws ?
Plants reproduce in a pattern known as alternation of generations. A haploid gametophyte produces gametes through mitosis. The gametes fuse to form a zygote, which then grows into a diploid sporophyte. The sporophyte produces spores through meiosis, which then grow into a gametophyte and start the process over.
Flowers are how angiosperms reproduce. A whorl of sepals (corolla) is at the base of the flower, followed by a whorl of petals (calyx). Inside the flower is a female organ known as a carpel and it is made of a stigma, style, and ovary. The male organ is the stamen and it is made of an anther and filament.
Pollen being transferred to the style is known as pollination. Once the pollen travels down the style and reaches the egg, fertilization happens when sperm meets egg. Then, the fertilized egg and surrounding tissue develops into a seed. A seed is protected by a seed coat and contains endosperm and an embryo. The endosperm grows into a new plant while…

- Sexual vs. Asexual Reproduction: What is one cost to the parent plant of retaining the newly formed offspring on the parent plant until the offspring is established in the ground? The parent plants cost is the energy needed to produce sugar to supply to the developing offspring as the offspring has no source for attaining carbohydrates. The parent plants cost is it needs to supply the offspring with CO2 for photosynthesis. The parent plants cost is the energy to grow more roots so it can supply the offspring with water and nutrients. The parent plant needs to defend the offspring from herbivory.

- The drooping, bell-like flower Aquilegia canadensis is adapted for cross-pollination. However, if the plant has not been pollinated previously, self-pollination can occur. However, if cross pollination occurs after self-pollination takes place, the pollen from cross pollination reaches the style before the pollen from self-pollination. Using course concepts and vocabulary 1) Provide a reasoning for this phenomenon. 2) Would this adaptation for reproduction be beneficial for the plant?arrow_forwardThe pineapple plant that is growing here is through vegetative reproduction (asexual reproduction). Unlike sexual reproduction, in asexual reproduction there is no genetic variation. True Falsearrow_forwardDirections: Plants have two life stages. The gametophyte life cycle, wherein a haploid spore is produced, and the sporophyte life cycle wherein there is union of the gametes. Below are different events in the development of flowering plants. Arrange them in the correct order. Place the number from 1 to 6 inside the box. The hypocotyl pushes to the soil along with the cotyledon(s). It starts as a seed which contain the miniature plant called embryo. Of the two sperm cells, one sperm fertilizes the egg cell, forming a diploid zygote; the other sperm fuses with the two polar nuclei, forming a triploid cell that develops into the endosperm Mature plant develops the gametes, releases the pollen and pollinates the flower. It is the process wherein seeds are transported, spread or moved away from the parent plant either by wind, water, animals or insect. The plant, given enough nutrients will develop in a mature stage.
