Name__________________________________________ Period _______ “Flowers to Seeds” Reading Guide As your read “Flowers to Seeds” on pgs. 40-44, answer the following questions completely. 1. What is the purpose of flowers?____________________________________________________________ ______________________________________________________________________________________ 2. Flowers reproduce __________________________ which means that a male cell and a female cell must unite to produce a new life the next generation of that plant. 3. The most visible and showy parts of the flower are the ________________. Around the base of the petals where the flower attaches to the stem, are some green leaf-like structures called____________________. 4. The reproductive parts of the flower are in the middle. Reaching up from the center of the flower are several _______________________, the male parts of the flower. Each stamen has two parts, the long, thin _______________________ that is tipped with an ________________________. Thousands of ______________________ _______________________ form in the anthers. Inside each pollen grain is the specialized male sex cell, the ________________________. 5. Right in the middle of the flower is the _______________________, the female part of the flower. The flattened tip of the pistil is the ________________________, and the base of the pistil deep inside the center of the flower is the _________________________. Inside the ovary are the __________________________, the “nests” in which the specialized female sex cells, the ________________, reside. That’s a flower. 6. In a flower what do we call when the two sex cells meet and unite? _______________________________ 7. Many plants can be pollinated only by pollen from other plants of the same kind. How does pollen get from one plant to another? (List & Describe the two ways) 1. __________________________ - ____________________________________________________ _________________________________________________________________________________ 2. __________________________ - ____________________________________________________ __________________________________________________________________________________ 8. Explain how bees pollinate flowers. _______________________________________________________________________________________ _______________________________________________________________________________________ _______________________________________________________________________________________ 9. What is a pollinator and how might one be attracted to a plant? _______________________________________________________________________________________ _______________________________________________________________________________________ _______________________________________________________________________________________ 10. After successful fertilization, a single cell divides and eventually developed into an embryo, then the development stops. The parent plant supplies the embryo with a package of energy-rich food, the future ______________________, and wraps the whole system in a weatherproof coat. The plant has just produced a ___________________________. 11. A fruit is: _____________________________________________________________________________ ______________________________________________________________________________________
