Potato is a stem modification whereas sweet potato is modified root,but both are performing the same function of storage of food. Thus they are an example of analogous organs.
How are sweet potatoes and potatoes analogous?
Potato and sweet potato are examples of analogous organs. Both sweet potato and potato have a common function i.e., storage of food in the form of starch. Hence, they show convergent evolution. But they both differ in structural origin as the sweet potato is a root modification while the potato is a stem modification.
Is sweet potato and potato homologous?
But they both differ in structural origin as the sweet potato is a root tuber, while the potato is a stem tuber. Thus, option B is correct, potato and sweet potato are not homologous organs, have not been introduced to India and are not two species of same genus.
How are sweet potatoes related to potatoes?
Sweet and regular potatoes are both considered root vegetables but are only distantly related. Sweet potatoes are from the morning glory family, Convolvulaceae, and white potatoes are nightshades, or Solanaceae. The edible part of these plants are the tubers that grow on the roots.
Is sweet potato analogous or homologous to potato tuber Give reasons to support your answer?
Solution : Sweet potato is analogous to potato tuber because they have a common function of storage of starch but differ in their structural origin, sweet potato (root), potato (stem).
What is difference between sweet potato and potato?
Regular potatoes have white or yellow flesh inside, while sweet potatoes are known for having orange innards. Both typically have brownish skin; though, that can vary depending on the variety. There are more than 4,000 different types of potatoes and 1,000 varieties of sweet potatoes grown around the globe.
Is sweet potato and potato convergent evolution?
Convergent evolution creates analogous structures that have a similar form or function but were absent from the last common ancestor of this group. Sweet potato tubers and potato tubers are the examples of analogous organs and analogous organs developed due to convergent evolution.
Which is homologous to sweet potato?
Since both turnip and sweet potato have the same origin thus, it can be said that they are homologous to one another.
What is the analogous structure?
Analogous structures are features of different species that are similar in function but not necessarily in structure and which do not derive from a common ancestral feature (compare to homologous structures) and which evolved in response to a similar environmental challenge.
What are analogous structures a result of?
Analogous structures develop due to convergent evolution where in organisms belonging to different species are exposed to the same environemental conditions and they adapt similarly.
Is sweet potato actually a potato?
Sweet potatoes are not potatoes
Unlike regular potatoes, which are tubers, sweet potatoes are considered to be root vegetables. The root, however, is described as a tuberous root. Both sweet and regular potatoes grow under the soil, but they are very different when it comes to density, taste and nutrition.
What is a group of potatoes called?
There isn’t a collective noun for a group of potatoes.
What family is sweet potato?
The many varieties of sweet potatoes (Ipomoea batatas) are members of the morning glory family, Convolvulacea.
Is sweet potato a root or stem?
Unlike the potato, which is a tuber, or thickened stem, the sweetpotato that we eat is the storage root of the plant; an enlarged lateral root.
What type of modification of root is found in sweet potato?
Adventitious roots
Adventitious roots– The roots of the plant like sweet potato are modified to store food and water. It is known as a root tuber. The roots of sweet potato grow from any other part of the plant. Stem- In potato, the stem is modified as a stem tuber for food storage.
Which of the following are not analogous organs?
Thorns of bougainvilla and tendril of Cucurbita do not have the same function and thus, could not be called as analogous organs. Was this answer helpful?
How are potatoes and sweet potatoes different biology?
Potatoes and sweet potatoes are both originally from America, belong to the tuberous plants and look – more or less – similar. Botanically, they are not related to each other. The potato (Solanum tuberosum) is a nightshade plant, the sweet potato (Ipomoea batatas), however, belongs to the bindweed family.
Why is sweet potato sweeter than potato?
Perhaps unsurprisingly, boiled sweet potatoes contain more than 14 times the amount of sugar of regular boiled potatoes (11.6g compared to 0.8g per 100g). The majority of the sugar in sweet potatoes is from sucrose, with glucose and fructose making up the minority (1).
Can dogs eat sweet potatoes?
When feeding your dog a sweet potato, make sure it’s cooked and that the skin is removed; leaving the skin on makes it harder for your dog to digest. You should never feed your dog a raw sweet potato. Not only are they difficult to chew, but they can upset your dog’s stomach and potentially cause intestinal blockage.
Why are analogous structures a result of convergent evolution?
Analogous structures are anatomically different but perform similar functions and hence are a result of convergent evolution. It occurs when two groups of largely unrelated organisms are exposed to very similar environments and develop similar adaptations to survive.
What is convergent evolution?
In evolutionary biology, convergent evolution is defined as the process whereby distantly related organisms independently evolve similar traits to adapt to similar necessities.
