Study Notes
Reproduction in Plants
- Plants can reproduce asexually by growing new shoots from underground stems, forming runners, or producing suckers from roots
- Plants can reproduce sexually by forming seeds
- Spore-bearing plants are the most numerous plant species on Earth
- Ferns and mosses reproduce by forming spores
- Angiosperms reproduce sexually by forming seeds
- Angiosperms are flowering plants and make up over half of all known plant species
- Meristematic cells are specialized cells in plants that allow for repair and asexual reproduction
Asexual Reproduction in Plants
- Western wood lily (Lilium philadelphicum) reproduces asexually
- Spider plants reproduce asexually through runners
- Strawberries reproduce asexually through runners
- Lilacs reproduce asexually through suckers
- Asparagus reproduces asexually from roots
- Growers may sell only the roots of asparagus plants
Bacterial Conjugation
- Bacteria can transfer genetic material directly from one cell to another through bacterial conjugation
- Bacterial conjugation is a primitive form of sexual reproduction
- Conjugation results in genetic recombination but not reproduction because it does not involve the production of new cells
- New cells are produced through binary fission after conjugation
Types of Plants
- There are approximately 35,000 species of spore-bearing plants, 700 species of gymnosperms, and 200,000 species of angiosperms living on Earth
Factors Affecting Plant Survival
- Spore-bearing plants require moisture for reproduction
- Climate change can affect plant survival by altering conditions needed for reproduction
Asexual Reproduction in Duckweed
- Duckweed is a small aquatic plant that reproduces asexually
- Duckweed produces two or three daughter fronds from each parent plant
- A new duckweed plant can form within 24 hours under suitable conditions
- Daughter fronds detach from the parent frond as they grow larger
