1 + * Give 2 examples of Natural Vegetative Reproduction * Give 1 reason why Natural Vegetative Reproduction is important Answer p. 18- 19 of the activity book (Act. 5.1) Day 1

2 + Vegetative Regeneration Asexual reproduction Can be Natural or Artificial using parts of the plant for reproduction aside from the flowers Natural-occurs in nature and plants do this on their own Artificial-man made way of reproducing plants using plant parts Flowering plants also reproduce sexually Two parent plants are needed Day 1

3 + Help conserve or increase the population of rare or endangered plants Better crops in a shorter time period Requires less care and attention Risk of total destruction of an entire crop of plants as the plants produced are prone to the same disease Competition for nutrients and overcrowding due to fat growth ADVANTAGESDISADVANTAGES

4 + Use a learning aid: TABLE Natural Vegetative Regeneration descriptionexamples Underground stems suckers leaves Artificial Vegetative Regeneration descriptionexamples Cutting Grafting Budding Air layering

5 + Natural Vegetative Reproduction Asexual Reproduction in Plants

6 + Natural Vegetative Regeneration Stems which grow underground Potato, ginger, onion UNDERGROUND STEMS

7 + Natural Vegetative Regeneration Part of the stem that shoots upright Banana, pineapple and heliconia (birds of paradise) SUCKERS

8 + Natural Vegetative Regeneration Usually those which are thick and fleshy Small leaves form alongside the leaves. The small leaves develop roots These small leaves and roots fall off to the ground and may develop into new plants. Begonia and bryophyllum Leaves

9 + Artificial Vegetative Reproduction Asexual Reproduction in Plants

10 + Artificial Vegetative Regeneration Plant part is cut, transplanted to the soil so it can grow into a new plant STEMS Used in most garden plants with woody stems Conditions: leaves are removed, soil must be moist and sun is kept away Hibiscus, chrysanthemum, basil, rosemary, geranium CUTTING

11 + Artificial Vegetative Regeneration Plant part is cut, transplanted to the soil so it can grow into a new plant ROOTS Plants with woody stems Conditions: roots is transplanted just below the soil Roses, jade plant, japanese angelica tree, blue passion flower CUTTING

12 + Artificial Vegetative Regeneration Plant part is cut, transplanted to the soil so it can grow into a new plant LEAVES One new plant from leaf base; others can be multiple plants in a leaf base Conditions: base of the leaf is planted in moist soil then leaves will start growing from the base African violet, sansevieria, snake plant, peperomia CUTTING

13 + Artificial Vegetative Regeneration Growing one part of a plant in another part of a plant A stem with a leaf bud is cut from a parent tree (GRAFT) Another plant is selected for its root system (STOCK) Graft is inserted to the stock and bounded but kept moist and away from the sun Method used for fruit trees such as apples, avocado and guava GRAFTING

14 + Artificial Vegetative Regeneration Bud is inserted to a stock plant The bud is tied and when bud grows into a shoot, the part above the shoot is cut Fruit trees and leafy trees such as peach and orange trees BUDDING

15 + Artificial Vegetative Regeneration Bark of branch is stripped; this wound is covered with soil The wound develops roots and is transplanted to soil. This will eventually develop into a new plant Method used for plants that take a long time to develop roots such as fruit, woody or indoor plants Lychee and pomegranate AIR LAYERING

16 + What is the significance of the knowledge of vegetative regeneration to our country and to us as individuals?
