- Both gymnosperm and angiosperm bear seed ,then why are they classified seperatedly?The sporophyte generation in higher plants include which of the following: 1) seta 2) plant embryo 3 ) anther 4) embryo sac 5) seed cone 6) fruit 7) pollen grain 8.) needle-like leaves 9) protonemata 2. Which characterize Gnetum gnemon? 1 ) netlike venation 2) tracheary elements (vessels and tracheids 3) naked ovules 4) linear, entire leaves 5) dioecious flowers 6) parallel venation 7) vessels 8. broad, entire leaves 9) tracheids 10) ovary walls 11) monoecious flowersMost of the approximately 900 species of gymnosperms are conebearing plants. On the surfaces of their cone scales are ovules, which later become seeds. These ovules are said to be naked because they are not completely enclosed by diploid tissue (as the ovules of angiosperms are). This characteristic gives the gymnosperms their name; gymnos is a Greek word meaning naked, and sperma means seed. Botanists now divide the gymnosperms into four groups: conifers, cycads, ginkgos, and gnetophytes.
- Are gymnosperms heterosporous or homosporous? Explain what this means. What are the evolutionary "advances" represented by the seed? Edit View Insert Format Tools Table 12pt v Paragraph v BIU A v O words ...What 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 ecosystemsHow are the gymnospermseeds formed? What are theploidies of the structures thatcompose the seeds?
- What is megasporophyll of angiosperm called?Which of the following statements characterize the megaphyll line of evolution? A) They differ from microphylls by developing a single, unbranched vein rather than a branched vascular system.B) They are believed to have evolved from branching telomeres that flattened and developed photosynthetic tissue between the branches.C) They developed into leaves that can also be called lycophyllsD) They developed into the large leaves of the angiosperms1) Read the following paragraph carefully. There are several mistakes within the paragraph. The ancestors of seed plants are thought to have been heterosporous. In modern day gymnosperms, megasporangia produce the gametes that give rise to the male gametophyte. Gymnosperm and angiosperm megasporangia have one integument layer. The megasporangia is haploid and makes the megaspore. a) How many mistakes are in the above paragraph? b) Rewrite the paragraph to be correct. Underline any changes you make to correct the statements.
- Another distinguishing feature of gymnosperms is that they have resin ducts, which conduct complex chemical compounds such tar, resins and turpentine. What is the function of these three chemicals?What is microsporophyll of angiosperm called?Which of the following statements best compares the two dominant lineages of modern angiosperms? -Monocots are monophyletic whereas eudicots have multiple origins. -Monocots have only one pistil per flower whereas eudicots have three. -Monocots have only one cotyledon whereas eudicots have two. -Monocots are lycophylls whereas eudicots are euphylls. -Monocots have only one stamen per flower whereas eudicots have six.
