Fragmentation in Biology

Click on the flashcard to see the answer



What is fragmentation in biological terms?

Fragmentation in biology is a form of asexual reproduction where an organism breaks into parts, each capable of growing into a new organism.

Name a plant that can reproduce through fragmentation.

A common example of a plant that reproduces through fragmentation is the spider plant, also known as Chlorophytum comosum.

How do starfish regenerate through fragmentation?

Starfish are capable of regenerating lost arms, and in some cases, a single arm can grow into a complete starfish given enough time.

What role does fragmentation play in vegetative propagation?

Fragmentation is a key mechanism in vegetative propagation, allowing plants to reproduce asexually from parts such as leaves, stems, or roots.

How does DNA fragmentation contribute to genetic studies?

DNA fragmentation is used in genetic studies to analyze DNA sequences through techniques like gel electrophoresis or PCR.

What organism uses fragmentation as a primary mode of reproduction?

Fungi, such as mushrooms and molds, often use fragmentation as a primary method of reproduction.

What advantage does fragmentation provide to organisms?

Fragmentation allows rapid population increase and colonization, particularly in environments that support the quick growth of new fragments.

Why is fragmentation beneficial for some marine species?

For marine species like sponges, fragmentation allows individuals to restore themselves from small pieces, helping them survive in dynamic underwater environments.

How is fragmentation used in tissue culture?

In tissue culture, fragments of plant tissues are used to propagate clones under sterile lab conditions, enhancing growth rates.

What is a challenge associated with fragmentation in reproductive strategies?

A challenge is the lack of genetic diversity, as offspring are clones of the parent, leading to susceptibility to diseases and changing environments.

How do some algae utilize fragmentation for growth?

Algae often undergo fragmentation when pieces break off, and each can grow into fully functional organisms, especially in aquatic environments.

Why is fragmentation notable in the reproduction of planarians?

Planarians can reproduce through fragmentation, wherein even small body sections can regenerate into new individuals.

How do bryophytes use fragmentation?

Bryophytes, such as mosses, use fragmentation to spread vegetatively when parts of the plant naturally break and establish new growth areas.

Explain fragmentation in terms of ecological impact.

Fragmentation allows certain species to quickly colonize new areas, affecting ecosystem patterns and dynamics through rapid population growth.

What characteristics make an organism suitable for fragmentation?

Organisms suitable for fragmentation typically have simple body structures and high regenerative capabilities, such as some fungi, algae, and invertebrates.
