If plants possess male and female reproductive structure on different plants it is termed as heterothallic condition . If a flowering plants possses unisexuall male flowers with only androecium it is called as staminate flower with only gynoecium it is called as pistilate flower .
What is heterothallic condition?
Medical Definition of heterothallic
: having two or more morphologically similar haploid phases or types of which individuals from the same type are mutually sterile but individuals from different types are cross-fertile.
What is difference between staminate and pistillate flowers?
A staminate flower contains stamens only while a pistillate flower only contains carpels or pistils. This is the major difference. Stamens are male reproductive organs while pistils are female reproductive structures. Out of the many other structures of a flower, stamens and pistils are the reproductive parts.
What is heterothallic condition give an example?
In heterothallic fungi, two different individuals contribute nuclei to form a zygote. Examples of heterothallism are included for Saccharomyces cerevisiae, Aspergillus fumigatus, Aspergillus flavus, Penicillium marneffei and Neurospora crassa.
What is Homothallic condition Class 12?
Homothallism refers to a condition where hyphae are genetically compatible and therefore forming zygospores from two branches of the same mycelium. Whereas, heterothallism refers to a condition where two complementary mating types are needed for sexual reproduction.
What is difference between homothallic and heterothallic?
The main difference between homothallic and heterothallic is that homothallic is the condition of having both male and female reproductive structures on the same thallus whereas heterothallic is the condition of having male and female reproductive structures in different thalli.
What is heterothallic and dioecious?
is that heterothallic is (botany|of some algae and fungi) producing male and female reproductive structures in different plants while dioecious is (botany) having the male and female reproductive organs on separate plants (of the same species) rather than different parts of the same plant.
What do you understand by staminate and pistillate flowers give two examples?
Staminate flowers produce pollen grains. Pistillate flowers produce ovules. An example of a staminate flower is Chrysanthemum. An example of a pistillate flower is squash.
What are staminate flowers Class 12?
Staminate flowers are those that have only male reproductive organs, or stamens, or have infertile female organs.
What is meant by Staminate flower?
Definition of staminate
1 : having or producing stamens. 2 of a diclinous flower : having stamens but no pistils.
What is the example of staminate flower?
Eggplant, cucumber, chrysanthemum are examples of plants producing staminate flowers. The flowers, which consists of male reproductive structures or stamens, are called staminate flowers. These flowers lack female organs, such as pistillate.
What is a homothallic condition?
Homothallic refers to the possession, within a single organism, of the resources to reproduce sexually; i.e., having male and female reproductive structures on the same thallus. The opposite sexual functions are performed by different cells of a single mycelium. It can be contrasted to heterothallic.
What are some examples of pistillate flowers?
Examples of pistillate flowers are Chrysanthemum, cucumber, eggplant, squash etc. When the same plant grows flowers of both the sexes, it is called a monoecious plant.
What is difference between homothallic and monoecious?
As adjectives the difference between homothallic and monoecious is that homothallic is (of some algae and fungi) producing male and female reproductive structures in the same plant while monoecious is (botany) that has male and female reproductive organs on the same individual plant (rather than on separate individuals …
Is heterothallic the same as dioecious?
Heterothallic and dioecious :- when male and female organs are present in different thalli of fungi they are termed as heterothallic fungi. unisexual plants are also called as dioecious . When either male or only female is present in the plant it is called as dioecious plants .
What is Homothallism and heterothallism in fungi?
Fungi have evolved two paradigmatic sexual systems: heterothallism and homothallism (Figure 1). Heterothallic fungi require two compatible partners for mating to occur, whereas homothallic fungi are self fertile with a single individual capable of sexual reproduction even in solo culture.
