Asexual Reproduction in Plants Headings Vocabulary Important Info

Offspring will have same genes as parents Vegetative Propagation: Producing new individuals from roots, stems, or leaves of existing plants Examples: Runners- modified stems that grow along the top of the ground & send out their own roots Strawberries

2. Rhizomes- modified stems that grow under the soil, produce new roots from stem. Ex- Grasses 3. Tubers- shorter, thicker stems that produce an “eye” which is capable of producing a new plant. Ex-Potato

4. Bulbs- Stem covered with modified leaves which can produce a new plant Ex: Onion 5. Food Storing Roots- Roots which are capable of producing a new plant Ex: carrots & beets

Artificial Propagation Method of Asexual reproduction most used in agriculture 1. Cuttings- pieces of stem cut from parent kept in water, moist soil or sand Will put out new roots. Ex:-Many garden plants

2. Grafting- Buds or sections are cut from one plant Attached to another that is already rooted in the soil. Ex- Roses, Fruit Trees 3. Tissue culture- pieces of the center of stem are removed placed in flasks with growth medium a whole new plant will develop

Photosynthesis in Plants Chlorophyll- green pigment in plants Converts light energy to chemical energy in the form of carbohydrates Sugars can be broken down to release ATP Photosynthesis- process where plants trap energy to build carbohydrates 6CO2 + 6H2O + sunlight energy  C6 H12 O6 + 6O2

CELLULAR RESPIRATION C6H12O6 + 6O2  6CO2 + 6H2O + Energy (ATP) Reversed Photosynthesis Equation Cellular respiration is what cells do to break up sugars into a food that the cell can use as energy. This happens in all forms of life. Cellular respiration takes in food and uses it to create: ATP chemical which the cell uses for energy. Some simple organisms can only go through anaerobic cellular respiration.
