What is connective anther?
Plant Morphology (Thus, anthers are typically tetrasporangiate.) The tissue between and interconnecting the two thecae is termed the connective, to which the filament (if present) is attached.
What are the different types of anthers?
Anther Types
- Bilobed: It is the most common type that consists of a bilobed structure, which occurs in all mature stamens of the angiosperms.
- Unilocular: It consists of a single lobe like the members of the Malvaceae family.
- Linear: This occurs in the genus Acalypha.
- Rounded: It appears in the genus Merculiaris.
When the petals are fused with one another is known as?
Connation in plants is the developmental fusion of organs of the same type, for example, petals to one another to form a tubular corolla. This is in contrast to adnation, the fusion of dissimilar organs. Such organs are described as connate or adnate, respectively.
When stamens are fused by their anthers?
Epipetalous refers to the condition where stamens are fused with petals. – The androecium of syngenesious is a feature of the family Asteraceae where the anthers are fused but the filaments are free. – It is a condition about an aggregate of stamens fused at the anthers.
What do anthers contain?
pollen
Anthers are discrete pollen containing units, found in the stamens of the great majority of angiosperms. Anthers typically consist of two compartments called thecae (singular theca), with each theca containing two microsporangia (the fusion product of which is a locule). (Thus, anthers are typically tetrasporangiate.)
What are anthers in plants?
Anther: The part of the stamen where pollen is produced. Pistil: The ovule producing part of a flower.
Where are the anthers on a plant?
Plant Morphology Anthers are discrete pollen containing units, found in the stamens of the great majority of angiosperms. Anthers typically consist of two compartments called thecae (singular theca), with each theca containing two microsporangia (the fusion product of which is a locule).
Where is anther located in flower?
stamen
The anther is a key structure in the reproduction of flowering plants. It sits atop the filament of the male structure known as the stamen.
When both anthers and filaments are fused the condition is known as?
Hence, the correct answer is ‘Syngenesious’.
When anthers are unites and filaments are free it is known as?
When stamens are fused by their anthers and filaments are free then this condition is called as gynandrous. Explanation: The condition is revealed as the gynandrous condition which holds the stamen and pistil united in one column, as in the orchids characterized by hermaphroditism.
