Where do scientists believe plants evolved?
Scientists believe that plants evolved on land from green algae, specifically from a group called charophytes. This transition from water to land occurred around 450 million years ago during the Ordovician period.
What organelle does the endosymbiotic theory suggest evolved from the symbiotic relationships between prokaryotic cells?
The endosymbiotic theory suggests that mitochondria and chloroplasts evolved from symbiotic relationships between prokaryotic cells. More specifically, mitochondria are proposed to have originated from aerobic bacteria, while chloroplasts are thought to have originated from photosynthetic bacteria.
What evolved from prokaryotes?
Eukaryotic cells evolved from prokaryotes.
What is an example of an analogous structure?
An example of an analogous structure is the wings of birds and the wings of bats. Both structures have a similar function (flying) but are made of different materials and have evolved separately in these two distinct groups of animals.
What does form and function mean in life science?
In life science, form refers to the physical structure or characteristics of an organism, while function refers to the specific role or purpose that a structure or characteristic serves in the organism's survival or reproduction. Understanding the relationship between form and function is essential for studying how organisms have evolved to adapt to their environments.
What was the structure of the killer whale before it evolved?
_ _ / - - _ _ - - \ _ _
Which annelid structure resembles the ancestral structure from which the vertebrate kidney evolved?
nephridium
What structure have they evolved to obtain gamete exchange?
Pollen
What is the specialized reproductive structure that evolved most recently is the?
ovary
What is deposit-feeding?
deposit-feeding is one of the five different types of feeding adaptions that have evolved among animals. Deposit feeders feed on the particles of matter in the soil (normally the sediment) that contain orangic matter. examples of deposit-feeders would include earthworms, terribellids, and fiddler crabs.
Feathers are thought to have arisen from what structure?
reptile scales
What structure have seed plants evolved to obtain gamete exchange?
The answer, I believe, is pollen.Pollen is correct.== == == ==
The human appendix is a structure that suggests that humans evolved from plant-eating ancestors?
vestigal
A similar feature that evolved through convergent evolution is called a?
It's homoplasy.
When a structure that has evolved in one context becomes co opted for another purpose this event is called?
exaptation
How have fossil organisms changed throughout geological history?
They have evolved. There entire structure has changed, like their skeleton and their appearance.
Where do scientists believe plants evolved?
Scientists believe that plants evolved on land from green algae, specifically from a group called charophytes. This transition from water to land occurred around 450 million years ago during the Ordovician period.
