Summary Introduction
To review:
The structural and biochemical features of gymnosperms (such as conifers) that might result in slower growth, therefore, putting them at a competitive disadvantage with respect to
Introduction:
Vascular seed plants include two major groups that are angiosperms and gymnosperms. Gymnosperms are naked seed plants whereas, angiosperms are flowering seed plants. Conifers are the most widespread gymnosperms.

- Which of the following traits characterizes gymnosperms? a. The plants carry exposed seeds on modified leaves. b. Reproductive structures are located in a flower. c. After fertilization, the ovary thickens and forms a fruit. d. The gametophyte is longest phase of the life cycle.arrow_forwardMost extant species of gymnosperms are now considered as "living fossils", why is that so? Give some insights on why gymnosperms were not able to dominate land despite of having seeds.arrow_forwardWhich of the following is the MOST likely explanation for the evolutionary success of angiosperms? A. Angiosperms have complex and successful interactions with animals leading to effective pollination and seed dispersal. B. Angiosperms have a vascular system that allows plants to grow tall and spread spores farther. C. Angiosperms have stomata that allow conservation of water. D. Angiosperms developed seeds and pollen, which allow reproduction to be independent from water.arrow_forward
- Ferns are a type of terrestrial plant that does not produce seeds, unlike gymnosperms and flowering plants. This significant evolutionary divergence contributed to the dominance of gymnosperms and flowering plants. How might the ability to produce seeds have advantaged these groups? It allowed these plants to photosynthesize more efficiently. It allowed these plants to attract more pollinators. It allowed these plants to better disperse, colonize new habitats, and survive drier conditions. It allowed these plants to grow taller and compete for sunlight.arrow_forwardWorking in the field, you discover a fossil of a previously undescribed plant species.The specimen is small and may not be complete; the parts you have do not include floral organs. what sort of observation(evidence) would you nrrd in order to classify the fossilas a vasucular plant with reasonable accuracy?What evidence would you need to distinguis between an angiosperm and gymnosperm? Answer should be a maximum of 170 wordsarrow_forwardYou have been hired as research assistant to investigate the origins of the angiosperms, specifically the boundary between a gymnosperm and an angiosperm. Which characteristics would you use to clearly define a new fossil as a gymnosperm? An angiosperm?arrow_forward

The seeds of gymnosperms are "naked"; angiosperm seeds are contained within a fruit.arrow_forwardImagine that you are a member of a research group conducting research on fruit type and seed dispersal. Your group has submitted a paper to a peer-reviewed journal that addresses the factors that impact fruit type and seed dispersal mechanisms in plants of Central America. The editor of the journal communicates that your paper may be published if you make ‘minor revisions’ to the document. Why is seed dispersal important in the life of plants? What would be the consequences of having seeds that simply fell to the ground underneath the parent tree? Please be detailed as possiblearrow_forward
