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 plant structures do angiosperms possess that are not found in any earlier lineage of plant? A. Fruits B. Seeds C. Pollenarrow_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_forward
- In the evolution of seed plants, explain when seed plants first appeared and how gymnosperms became the dominant plant group.arrow_forwardFerns 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_forwardExamine different root systems in angiosperm plants, draw labelled diagram and provide important features. a. Tap root system b. Fibrous root system c. Adventitious root systemarrow_forward
- Working 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_forwardWhat evolutionary advantages do seed provide over spores? What was early gymnosperm ecology like? What ecological role did gymnosperms perform as the dominant terrestrial plant type 250 million years ago? what were did angiosperms begin to replace gymnosperms as the new dominant plant type in terrestrial ecosystemsarrow_forward
- Which of the following adaptations possibly explain(s) why angiosperms are more diverse than gymnosperms on planet Earth: Group of answer choices Seeds Seeds AND Fruits and Flowers AND Pollen tube Fruits and Flowers Fruits and Flowers AND Pollen tube Pollen tubearrow_forwardTheophrastus of Lesbos, Aristotle’s successor as head of the Lyceum, improved upon Aristotle’s botany by classifying all monocotyledons as flowering plants with: two seed-leaves in the embryo, branching leaf veins, and flower parts in multiples of 4 or 5 one seed-leaf in the embryo, branching leaf veins, and flower parts in multiples of 4 or 5 one seed-leaf in the embryo, parallel leaf veins, and flower parts in multiples of 3 or 6 two seed-leaves in the embryo, parallel leaf veins, and flower parts in multiples of 3 or 6 two seed-leaves in the embryo, branching leaf veins, and flower parts in multiples of 3 or 6arrow_forwardMost angiosperms incorporate the assistance of animals in their reproductive cycle. This is a major advancement that gave them an advantage over other plant lineages and helped them become the dominant type of plant on Earth today.
