Evolutionary Developmentà VASCULAR TISSUE What is vascular tissue? Seedless Vascular Plants (vascular tissue, no seeds) How long ago do seedless vascular plants first appear in the fossil record? Name 2 types of seedless vascular plants that are extant: Evolutionary Developmentà SEEDS What is a seed? Seed Plants (vascular tissue, seeds) How long ago do seed plants first appear in the fossil record? There are 2 Types of Seed Plants: Gymnosperms Give 2 examples of modern plants that are gymnosperms: Angiosperms (flowering plants) Give 2 examples of modern plants that are angiosperms:
Today, the tallest bryophytes reach a maximum height of 20 centimeters (8 inches) or so. So far as we know from fossils, there were no giants among their ancestors. Lignin and vascular tissue first evolved in relatives of club moss, and some extinct species stood 40 meters (130 feet) high. Among modern seed plants, Sequoia (a gymnosperm) and Eucalyptus (an angiosperm) can be more than 100 meters (330 feet) high. Explain why the evolution of vascular tissues and lignin would have allowed such a dramatic increase in plant height. How might being tall give one plant species a competitive advantage over another?
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 angiosperms
1. Of the plant groups included in Figure 1-1, which taxes have seeds? 2. Are the angiosperms more closely related to the bryophytes or the gymnosperms? 3. Explain your answer to question #2 4. Circle the node in Figure 1-1 that indicates the most recent common ancestor of gymnosperms and angiosperms. 5. List the characters that differentiate monocots and eudicots ( two groups of angiosperms) as seperate branches on the phylogenetic tree. In addition, give several examples of each.
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 words
Which of the following is NOT a caharacteristic of all seed plants? 1. a sporic life cycle 2. cell walls containing cellulose 3. life cycle is dominant in the sporophyte phase 4. reproductive organs found in flowers 5.nearlly all are photo-autotrophic
items in bullet are options for the question above it When gymnosperms arose during the late Carboniferous era, around 300 million years ago, they were the first true seed-bearing plants. The word comes from gymno-, meaning "naked," and -wsperm, which refers to "seeds" not actual sperm. Gymnosperms have "naked seeds," because they do not encase their seeds in fruits as do angiosperms. 1. Gymnosperms were also the first plants to develop pollen. Which of the following statements correctly describes one of the advantages of pollen? The development of pollen means that gymnosperms no longer require sporophytes for reproduction. The development of pollen means that gymnosperms are not dependent on water for reproduction. Pollen is created by the sperm of the plant. 2. In gymnosperms, where are the female gametophytes located? In the ovulate cones The gametophyte stage no longer exists in gymnosperms In the needles or leaves…
One of the major phylogenetic conclusions of this study is: choose one a. The Ginkgoales are the sister group to angiosperms among extant gymnosperms. b. There is no sister group to angiosperms among extant gymnosperms. c. The Cycads are the sister group to angiosperms among extant gymnosperms. d. The Gnetales are the sister group to angiosperms among extant gymnosperms. e. The Conifers are the sister group to angiosperms among extant gymnosperms.
Rearrange the sequence of conifer life cycle 1. Seed cone allows the entry of wind- borne pollen grains, once enclosed pollen grain will slowly develop pollen tube 2. Small seeds can be carried away by wind and large seeds are dispersed by animals 3. In spring or in a windy day, thousands of pollen grains will disperse. 4. Seeds contains three tissues; embryo, seed coat and gametophyte 5. Conifers produce two types of spores; pollen cone that contains male gametophyte and a seed cone containing enclosing archegonia 6. Flagellated sperm will release to fertilize the egg and eventually develop into a tiny embryo 7. Once germinated, conifer establish first a good rooting system for protection and seeking nourishment.

What can you say about an early interpretation or hypothesis that the gnetophytes are probably the sister lineage of the angiosperms? Do you agree or not?
