Question:- Which of the following is FALSE about fruit? A. Mature ovary B. Protect seeds and aid in dispersal C. Exposes the seeds D. Produced by flowering plants
QUESTION 10 Which is true regarding plant reproduction? Self-pollination produces offspring genetically identical to the parent modified organs, such as corms and bulbs, are produced as a result of sexual reproduction cross-pollination allows plant populations to survive in unstable environments plants do not reproduce asexually vectors such as flies carry plant spores to new locations
TRUE OR FALSE 1. A lignified primary cell wall is one of the many apomorphies of vascular plants. 2. The sporophyte structure in vascular plants is dependent on the gametophyte structure. 3. The presence of lignin in the secondary cell wall structure of vascular plants acts as a cementing agent between cellulose fibrils.
Which of the follow correctly describe the function of a flower? Question 29 options: The reproductive structure of the angiosperms. Contains the plant embryo and a tissue such as endosperm to provide nutrition for early plant growth. Grows from the ovary of a flowering plants and surrounds the seed. Provides protection and/or attracts animals to aid in seed dispersal. Carries the microgametophyte and sperm cells during sexual reproduction in angiosperms. The reproductive structure of the gymnosperms.
PLEASE ANSWER NUMBER 1,2,3, and 4 QUESTIONS: (with brief explanation only) 1. A difference between seedless vascular plants and plants with seeds is that? A. the gametophyte generation is conspicuous in the seedless plants, whereas the sporophyte is dominant in the seeded plants. B. the spore is the agent of dispersal in the first, whereas the seed functions in dispersal in the second. C. the gametophyte is photoautotrophic in seedless plants but dependent on the sporophyte generation in the other group. D. the embryo is unprotected in the seedless plants but retained within the female reproductive structure in the other group. 2. Biologist hypothesize that the first land plants had a low, sprawling growth habitat. Which of the following is part of the logic behind that theory? A. The low sprawling growth gave them greater surface area exposed to light for photosynthesis. B. This was prior to plants’ development of adaptations to defend themselves from predators, so by growing…
T/F question The limiting factor for plants is phosphorus. Root hairs help to decrease the absorbtive surface area of a plant. Xylem conducts plant sugars and organic molecules. Plant tissues grow from meristem cells that continually divide during the growing season. Primary plant growth involves thickening of the stems and roots. Plants can undergo asexual reproduction without cross-pollination.
n the bryophytes, the main vegetative structures (such as the leaves of moss) are: Question 23 options: Haploid cells of the gametophyte. Haploid cells of the sporophyte. Diploid cells of the sporophyte Diploid cells of the gametophyte
Question #1. Briefly discuss and compare the plant habit and reproductive structures of the representative species of seedless vascular plants (Psilotum sp., Lycopodium sp., Equisetum sp., Selaginella sp., Adiantum sp., Ophioglossum sp., Angiopteris sp.)
Generally, immature fruits are green in color, and they change tobright, attractive colors when they become ripe. What do you think isthe potential evolutionary advantage of fruits changing colorconcerning their potential for dispersal? Please answer concisely and straight to the point. Thank you.
What does it mean to say that mosses and other nonvascular plants have life cycles dominated by gametophytes? asap please
Seeds and pollen grains are key adaptations for life on land. These adaptations relate to reproductive success and survival advantages. The following questions require you to explain some of these adaptations. A. Contrast sperm delivery in seedless plants with sperm delivery in seed plants. (5-6 sentence) B. Discuss at least one feature of seed plants that contributed to their success on land in contrast with seedless plants. (2-3 sentences) C. Flowering plants (Magnoliophyta) are the most successful of all plant groups in terms of their species diversity and ubiquity across habitat types. Climate warming is causing shifts in the timing of life history events for many species. Discuss how climate warming may influence reproductive strategies employed by flowering plants. (2-3 sentence)
