10.1 Sexual Reproduction in Flowering Plants In the plant life cycle, the pollen grain carries sperm to the egg located within a flower part.Following fertilization, growth and development are required for the zygote to become an embryo enclosed within a seed.Seeds must be dispersed and must germinate to complete the plant life cycle. | 1. What is meant by alternation of generations in the flowering plant life cycle? Answer2. What is double fertilization?

10.2 Asexual Reproduction in Flowering Plants Plants also reproduce asexually. This ability can be commercially utilized to mass produce identical plants. |
3. List several ways in which flowering plants can reproduce asexually. Answer
4. How might plant tissue culture be beneficial to plants as well as humans? Answer | Essential Study Partner Asexual Reproduction |
10.3 Control of Plant Growth and Development Plant growth and development are controlled by many internal and external signals.Various hormones help regulate plant growth and development.Flowering is influenced by genes and environmental signals. | 5. What are three stimulatory plant hormones and what are their functions? Answer 6. List two inhibitory plant hormones and their functions.

10.4 Transport in the Mature Plant Transpiration (evaporation of water) pulls water and minerals from the roots to the leaves in xylem.Stomata must be open for evaporation to occur.Osmotic pressure pushes organic nutrients in phloem, from where these nutrients are made to where they are used or stored. | 7. How does transpiration help water rise in xylem to the top of the plant? Answer8. What are two symbiotic relationships that help plants take up nutrients from the soil?
