Flash Cards: How do Organisms Reproduce?

Reproduction is essential for the continuation of species; it allows for the creation of new individuals that look similar to the parents.

DNA (Deoxyribo Nucleic Acid) carries genetic information and is responsible for inheritance and the production of proteins.

Chromosomes are thread-like structures made of DNA that carry genetic information and are found in the nucleus of cells.

Variation occurs due to the imperfect nature of DNA copying which can lead to slight differences in genetic material.

Variation enhances survival; it enables species to adapt to changing environments and increases the likelihood of species continuation.

The two main types of reproduction are asexual (one parent, no genetic variation) and sexual (two parents, genetic variation).

Budding in hydra and binary fission in bacteria are examples of asexual reproduction.

In sexual reproduction, gametes (sperm and egg) fuse to form a zygote that develops into a new organism.

Organisms are considered the same species if they exhibit similar characteristics and can interbreed to produce fertile offspring.

Reproduction maintains population stability by ensuring a consistent number of individuals within a species.

If a niche changes drastically, populations may die out, but some individuals with variations may survive and adapt.

No, DNA copying is not absolutely reliable; slight errors can lead to variations in the offspring.

The creation of additional cellular apparatus occurs alongside DNA copying to ensure both new cells can function.

Variation is the basis for evolution as it allows for natural selection, enabling species to adapt over time.

Significant errors can lead to non-viable offspring that cannot survive due to incompatible DNA.

Environmental changes can alter niche conditions, affecting survival rates and reproductive success of the species.

Yes, reproduction requires a significant amount of energy for processes like gamete production and nurturing offspring.

Reproduction fundamentally involves making copies of the blueprints (DNA) that dictate body design.

Global warming can impact habitats and lead to the death of temperature-sensitive populations, leaving only resilient variations.
