1. How does the ripened condition of an ovary wall allow you to determine the category of fruits? 2. In phylogenetics, what are sister groups? Synapomorphies? Clades? Nodes? 3. How do inflorescences differ? 4. What is the Linnaean system of classification and what are the appropriate endings for common ranks? 5. Why do gymnosperms lack \"fruits\"? 6. What are synapomorphies and how are they indicated on a phylogeny? 7. Why is the development of seeds considered to be a major advance in the evolution of plants? Solution In ripened condition , an ovary develops into a fruit, the ovary wall becomes the pericarp. ============================================ 2. In phylogenetics, what are sister groups? Synapomorphies? Clades? Nodes? Clades : Two clades are sisters if they have an immediate common ancestor. 3. How do inflorescences differ? inflorescence :it is a group of flowers arranged on a stem that is composed of a main branch . 4What is the Linnaean system of classification and what are the appropriate endings for common ranks? In the scientific classification of Linnaeus there are three kingdoms, isolated into classes, and they, thusly, into a term for rank-based characterization of living beings, as a rule. 5. Why do gymnosperms lack \"fruits\"? As the Gymnosperms do not produce flowers and ovaries synapomorphies : it is a characteristic present in a genealogical species Itis shared exclusively. It is in more or less modified form) by its evolutionary descendants. synapomorphies. : a character or attribute that is shared by at least two scientific categorizations and is gotten through advancement from a typical genealogical shape. 7. Why is the development of seeds considered to be a major advance in the evolution of plants? The development of the seed plants speaks to a noteworthy progress over the more primitive Bryophytes and greeneries. In plants and greeneries, single- celled, haploid spores are the essential means for attacking new living spaces. Spores have almost no sustenance stockpiling and once sprouted can\'t endure extraordinary changes in natural conditions. Additionally, both greeneries and greeneries require water for preparation while seed plants depend on air streams and bugs. The seed plants can finish their life cycle completely on dry land, the length of satisfactory soil dampness from the roots is accessible. Preparation happens inside defensive tissues of the sporophyte (called integuments) and requires no outside water. Seed- bearing plants create megaspores (expansive spores) in megasporangia that form into ovules and, at development, deliver seed. They likewise deliver microspores (little spores) in microsporangia that form into dust grains (male gametophytes) that convey the sperm to the female structures to fulfill fertilization. Fertilization must go before preparation..
