What is fragmentation in biological terms?
Click to flip
Fragmentation in biology is a form of asexual reproduction where an organism breaks into parts, each capable of growing into a new organism.
Click to flip
Name a plant that can reproduce through fragmentation.
Click to flip
A common example of a plant that reproduces through fragmentation is the spider plant, also known as Chlorophytum comosum.
Click to flip
How do starfish regenerate through fragmentation?
Click to flip
Starfish are capable of regenerating lost arms, and in some cases, a single arm can grow into a complete starfish given enough time.
Click to flip
What role does fragmentation play in vegetative propagation?
Click to flip
Fragmentation is a key mechanism in vegetative propagation, allowing plants to reproduce asexually from parts such as leaves, stems, or roots.
Click to flip
How does DNA fragmentation contribute to genetic studies?
Click to flip
DNA fragmentation is used in genetic studies to analyze DNA sequences through techniques like gel electrophoresis or PCR.
Click to flip
What organism uses fragmentation as a primary mode of reproduction?
Click to flip
Fungi, such as mushrooms and molds, often use fragmentation as a primary method of reproduction.
Click to flip
What advantage does fragmentation provide to organisms?
Click to flip
Fragmentation allows rapid population increase and colonization, particularly in environments that support the quick growth of new fragments.
Click to flip
Why is fragmentation beneficial for some marine species?
Click to flip
For marine species like sponges, fragmentation allows individuals to restore themselves from small pieces, helping them survive in dynamic underwater environments.
Click to flip
How is fragmentation used in tissue culture?
Click to flip
In tissue culture, fragments of plant tissues are used to propagate clones under sterile lab conditions, enhancing growth rates.
Click to flip
What is a challenge associated with fragmentation in reproductive strategies?
Click to flip
A challenge is the lack of genetic diversity, as offspring are clones of the parent, leading to susceptibility to diseases and changing environments.
Click to flip
How do some algae utilize fragmentation for growth?
Click to flip
Algae often undergo fragmentation when pieces break off, and each can grow into fully functional organisms, especially in aquatic environments.
Click to flip
Why is fragmentation notable in the reproduction of planarians?
Click to flip
Planarians can reproduce through fragmentation, wherein even small body sections can regenerate into new individuals.
Click to flip
How do bryophytes use fragmentation?
Click to flip
Bryophytes, such as mosses, use fragmentation to spread vegetatively when parts of the plant naturally break and establish new growth areas.
Click to flip
Explain fragmentation in terms of ecological impact.
Click to flip
Fragmentation allows certain species to quickly colonize new areas, affecting ecosystem patterns and dynamics through rapid population growth.
Click to flip
What characteristics make an organism suitable for fragmentation?
Click to flip
Organisms suitable for fragmentation typically have simple body structures and high regenerative capabilities, such as some fungi, algae, and invertebrates.
