Study Notes
Vegetative Reproduction in Humans
- Humans utilize cloning and tissue culture for vegetative reproduction, allowing mass production of plants with desired traits in fields and laboratories.
Modified Underground Stems
- Tubers are modified underground horizontal stems that are thick and fleshy, serving as storage organs for nutrients.
Above-Ground Horizontal Stems
- Stolons, or runners, grow horizontally above ground, developing new genetically identical plants at their nodes.
Condensed Underground Stems
- Corms are modified underground stems with condensed structure and fleshy scale-like leaves, primarily used for food storage.
Sub-Aerial Stems
- Rhizomes involve natural vegetative propagation through sub-aerial stems growing horizontally under the soil, giving rise to new shoots and roots.
Controlled Environment Techniques
- Hydroponics enables precise control over plant growth within controlled environments, optimizing conditions for plant development.
Asexual Reproduction Types
- Binary fission is the process where a single organism divides into two identical organisms and is a recognized method of asexual reproduction.
Fragmentation
- In fragmentation, the parent organism breaks into fragments, each capable of growing into a new individual.
Budding
- Budding occurs when a bud develops on the parent organism, eventually detaching to form a new individual.
Non-Asexual Reproduction Methods
- Sexual reproduction is not classified as a form of asexual reproduction in plants.
Cellular Division
- In mitosis, the parent organism duplicates its genetic material and divides into two distinct parts.
Grafting Process
- Grafting involves attaching a cutting from one plant to the stem of another rooted plant, promoting growth and stability.
Inducing Root Development
- Cutting is the process of planting a part of a plant, such as a stem or leaf, in soil to encourage root development.
Spores During Unfavorable Conditions
- Spores are sac-like structures that contain reproductive cells, allowing survival during unfavorable conditions.
Bending and Soil Covering
- Layering involves bending a stem to the ground, covering it with soil, to promote adventitious root formation.
Laboratory Culturing Technique
- Micropropagation is the technique used for culturing plant cells in laboratories to grow new plants from small tissue samples.
Spore Germination
- Sporulation is the process where spores are released from a sporangium, germinating to form new organisms.
Studying That Suits You
Use AI to generate personalized quizzes and flashcards to suit your learning preferences.
Description
Test your knowledge on plant propagation techniques such as cutting, grafting, and artificial vegetative propagation. Learn how new plants can arise from nodes present in the stem or by attaching cuttings from other plants to develop as a single plant over time.
