The calotropolis translator appartus may be found in plants, and gynoposien can be found in plants.The pollen grains, also known as structre polinia, are connected to andrecium in the various plant sections.Friend, could you please explain anything further about it, and if it’s at all feasible, could you also send me an image of pollinia that’s related to it, just in case you don’t mind?Many, many thanks, friend.
In asclepiadoids, the translation apparatus serves as the unit responsible for pollen distribution. The insect transports the whole translator along with its pollinia or pollen contents from one flower to another flower, where the pollen grains are placed on the stigmatic surfaces on the underside of the stigma-head.
Which plant translator apparatus is present?
Each flower has five pointed petals and a little, exquisite ″crown″ that rises from the center and holds the stamens. Together, these parts make up the flower. At the stigmatic angle, the pollen grains are organized in a structure known as pollinia, and they are adhered to a glandular disc with an adhesive substance (translator apparatus).
What is translator apparatus in calotropis?
Abstract. The translator apparatus is made up of two different parts: the corpusculum, which is attached to the margin of the stigmatic head between the anthers, and a pair of arms, which are used to attach the corpusculum to the pollinia of the adjacent anther halves. Both of these parts are located between the stigmatic head and the anthers.
What is translation mechanism botany?
During the process of pollination, a pollinium, also known as a pollinia, or a pair of pollinia is attached to the pollinator. Due to the sticky nature of pollinia, they frequently become entangled in the legs of the insect, and they are then transmitted from one plant to another. The name given to this particular process is the translator mechanism.
Which part of pollen grains produce pollen tube?
The male gametophytes of seed plants are responsible for the production of pollen tubes. Pollen tubes serve as conduits to convey male gamete cells from the pollen grain—either from the stigma (in flowering plants) to the ovules at the base of the pistil or straight via ovule tissue in some gymnosperms. This process occurs in flowering plants and gymnosperms alike.
In which of the following family the characteristic feature Tetramerous flowers are present?
(a) A flower with three sepals. (b) a flower with four separate petals.
What is translator in anther?
Answer in its Entirely: – The pollinia of the neighboring anther lobes are attached to a sticky center by means of caudicles, which are little stalks. During the process of pollination, they are passed along as a single unit. This is what most people mean when they talk about a translator.
Why is Calotropis called milkweed?
Because of the milky liquid or latex that pours out of the wound of the Calotropis plant whenever a leaf is plucked from the plant, these plants are appropriately referred to as milkweeds.
What type of inflorescence is in Acacia species of family Mimosaceae?
Cymose head (Acacia), spike, or racemose can be described as the inflorescence (Dichrostachys and Prosopis). Pedicellate or sub-sessile (in the case of Acacia), sessile (in the case of Prosopis), bracteate, actinomorphic, hermaphrodite, hypogynous, complete, tetra or pentamerous, and tiny are the characteristics of the flower of this plant.
In which of the following is translator mechanism found?
In several regions of the world, many varieties of Calotropis are regarded as undesirable weeds. It demonstrates a clip mechanism or a translator. Pollinia include grains of pollen in their structure. The pollinia are held in place by something called the corpusculum, which is a rough and sticky disc.
What is Cleistogamy in pollination?
Cleistogamy refers to the process through which plants are capable of self-pollination. The term ″closed marriage″ can also be written as ″cleistogamy.″ Cleistogamous flowers are the name given to the types of flowers that exhibit cleistogamy. It is well recognized in the family of grasses, which includes peas, peanuts, and pansy, among other members.
Who is the father of plant physiology?
Julius Sachs (1868) is considered to be the founder of the field of plant physiology.
Where is the pollen tube located?
When it comes to most angiosperms, the pollen tube has to go through an intermediary zone known as the style between the time pollen is deposited on the stigma and the time fertilization occurs inside the ovary (Figure 1).After growing through a stylar canal or a stylar transmitting tissue, the pollen tube eventually reaches the locule cavity of the ovary, which is where the ovule is situated.
Where are the pollen grains found?
The stamen is the component of blooming plants that is male. This structure is known as an anther and it is held up by a single stalk known as the filament. The four pollen sacs that are typically seen in the anther are what are responsible for the production of pollen grains. A single cell containing two male gametes is contained within each pollen grain.
What is the function of the filiform apparatus?
(I) The filiform apparatus contributes to the process of absorbing food. (II) The vegetative cells of the female gametophyte are known as antipodals. (III) The fusing of two polar nuclei and the male gamete always takes place before the pollen tube is allowed to enter the cell. (IV) The egg cell makes up the greatest portion of the embryo sac.
