5  ======================= #### Printed in the Philippines by [ ] 5 = What I Need to Know ----------------------------------------- - Lesson 1: Sexual Reproduction in Plants (Self and Cross- Pollination). - Lesson 2: Asexual Reproduction in Plants At the end of this module, you will be able to: - Differentiate Self-Pollination from Cross-Pollination - Describe the different modes of reproduction in flowering and nonflowering plants such as moss, fern, mongo and others What I Know ----------- 1. The following are agents of pollination, except [ ]. A. Dragonflies B. Butterflies C. Dogs D. Bees 2. It is an asexual reproduction which is through structural modification in the stem, root, or leaf of herbaceous or woody plant. E. Sexual Reproduction F. Natural Vegetative Reproduction G. Artificial Vegetative Reproduction H. Imperfect Vegetative Reproduction 3. Which plant can cross-pollinate? I. Rice J. Potatoes K. Tomatoes L. Summer squash 4. These are the methods used to improve the quality and production of plants. M. Natural Vegetative Reproduction N. Artificial Vegetative Reproduction O. Sexual Reproduction P. All of the above 5. Which of the following fruit tree did not undergo cross pollination? Q. Apple R. Guava tree S. Mango tree T. Pomelo 6. It grows from big bulbs made of a stem and has special type of leaves. U. Ginger V. Onions W. Garlic X. Avocado 7. What is the most common method of pollination? Y. Cross- pollination Z. Pollination A. Reproduction B. Self- pollination 8. It is a kind of plant that reproduce by spreading underground and growing new shoots. C. Mango D. Bamboo E. Chico F. Santol 9. What type of pollination happens when pollen grains are transferred from the anther of a flower to the stigma of another flower that belongs to another plant but of the same kind? G. Cross- pollination H. Imperfect pollination I. Perfect- pollination J. Self- pollination 10. It is a kind of plant that develops small plants along the edge of its leaves. K. *Katakataka* L. Banana M. Crabgrass N. Fern What's In ------------------------------- 1. The stigma is the structure which receives the pollen grains, stimulates the pollen grain to germinate and reach the ovary. 2. The ovary enlarges and thickens its walls to become a flower. 3. The stigma, style, and ovary are the female parts of the flower. 4. Stamen is the male part of the flower. 5. The tube releases the sperm cells into the ovule to fertilize the egg cell. What's New ----------  What is It ----------  (*Dignos.nd) (Dignos.nd)* What's More ---------------------------------- #### Activity 1 #### Column A Column B 1. It holds the anther in a high position a. style for release of pollen. 2. It connects the stigma to the ovary, b. stigma also traps the pollen grains. 3. This structure receives the pollen grains, c. filament stimulates the pollen grain to germinate 4. It is the transfer of the pollen grains 5. It is the transfer of pollen grains from the anther of a flower to the stigma of another flower #### Activity 2 4. [ ] is the transfer of pollen grains from the anther to the stigma of the same flower or of a different flower that belongs to the same plant. In 5. [ ] , the pollen grains are transferred from the anther to the stigma of a flower in another plant of the same kind. #### Activity 3 #### Illustration Venn Diagram +-----------------+-----------------+-----------------+-----------------+ | Following the | I can do this | I can do this | I am still | | directions | on my own | with help from | confused but am | | | | my parents | starting to | | | | | work | | | | | | | | | | on it | +-----------------+-----------------+-----------------+-----------------+ | Research and | I collected a | I collected | I only | | collecting | lot of | some | collected | | information | information | information | information | | | from other | from another | from this | | | books and the | book | material | | | | | | | | internet | | | +-----------------+-----------------+-----------------+-----------------+ | Completing the | I was able to | I was able to | I was not able | | tasks | | | to | | | complete the | complete to | | | | tasks on my own | tasks with some | complete the | | | | help | tasks. | +-----------------+-----------------+-----------------+-----------------+ | | I was able to | I only write | I only use the | | | use my own idea | the information | information I | | | and the new | that I have | get from this | | | information I | gathered from | material | | | learned to | the book I | | | | answer | | | | | | read | | | | the activity | | | +-----------------+-----------------+-----------------+-----------------+ | | I completely | I understand | I am close to | | | understand this | this but I feel | understanding | | | and fell like I | like I need | this, but I | | | could share | more | still | | | | | | | | it to others | practice | need help | +-----------------+-----------------+-----------------+-----------------+ **Lesson** ------------ -- **2**  What's In -------------------------------- 1.

It occurs when an axillary bud grows into a lateral shootand develops its own roots. New plants may sprout from stems, roots or leavesof a parent plant. Modified stems are most often the source of vegetative plant propagation. Vegetative plant structures that arise from plant stems include rhizomes, runners, bulbs, tubers, and corms. Tubers can also stretch from roots. Plantlets emerge from plant leaves. #### Runners #### Bulbs #### Tubers #### Rhizome #### Suckers  #### Plantlets 2. **Artificial Vegetative Reproduction** is also called cloning. This type of vegetative reproduction produces the next generation that is generally identical to the parent. The various way in artificial reproduction are cuttings, grafting, marcotting, layering, and budding. g. #### Cuttings #### Grafting #### Marcotting  #### Layering #### Budding  What's More ---------------------------------- #### Activity 1: Am I Natural or Artificial? 1.
