Exam Stuff Flashcards
Provide an example of an organism that reproduces through budding.
Hydra and yeast are examples of organisms that reproduce through budding, where a new organism develops from a growth on the parent.
How do eukaryotes like Amoeba and Paramecium undergo asexual reproduction?
Eukaryotes like Amoeba and Paramecium reproduce asexually through simple cell division, which involves the process of mitosis.
What is fragmentation, and which organisms commonly reproduce using this method?
Fragmentation is when an organism breaks into smaller parts, with each fragment developing into a mature organism. This method is common in filamentous cyanobacteria, molds, plants, and animals like sponges and sea stars.
What is vegetative propagation, and in which organisms does it occur?
Vegetative propagation is a form of asexual reproduction in plants. It is made possible due to the presence of undifferentiated cells in meristematic tissue and includes methods like runners, cuttings, rhizomes, tubers, bulbs, corms, and plantlets.
What is plant tissue culture, and how is it used in cloning?
Plant tissue culture is the process of growing clones of a plant from a small amount of tissue from one plant. It is used in cloning to produce genetically identical plants.
What are the advantages of plant tissue culture?
Slow-growing plants can be produced in large numbers.
Plants can be cultured year-round in controlled conditions.
Virus-free tissue can be used to produce plants that do not carry the virus.
Cultured plants can be transported internationally.
