The correct answer is "Carpel or Pistil." Both carpel and pistil serve as the female reproductive organs in a flower. A carpel comprises components such as the ovary, stigma, and style, while the pistil can be composed of multiple carpels or a single carpel. Rate this question: 20 4 ...
(the stamens grow to approximately 1 mm in length, the carpel is enclosed by the lemma and palea); 4) the yellow anther (YA) stage (development of the anthers and pollen is more advanced, the lemma and palea grow and completely enclose the stamens and carpel); 5) the tipping (TP)...

Each carpel is usually bowling pin-shaped, and features a sac at its base in the center of a flower, and this sac is the ovary that produces and contains developing seeds, or ovules. Moving upward, the ovary extends to support a style, that is a tube-like structure leading up to the...
At the ventral suture, where pod shattering first took place, the two vascular bundle valves in both species were jointed along the fused line of the carpel with parenchymal AL delimitating the vascular bundle valve (Supplementary Fig. 2e,f). It is obvious that the two ventral vascular bundle...
In this case, higher AIL7 mRNA levels resulted in dramatic changes in flower development including the production of bracts and mosaic floral organs, reduced numbers of floral organs, and fusion of stamens to central carpelloid structures. We found some of these same phenotypes in an ethanol ...

It is characterized by its obviously dentate leaf margins; a petal to stamen length ratio less than or equal to 1; crimson sepals, petals, and ripe fruits; and a carpel that is not developed in the staminat 来自 dialnet.unirioja.es 喜欢 0 阅读量: 48 作者: Li Xinwei,Shi Quanfen,...
sinensis is when the early gynoecium meristem is disrupted. During the early stage of HF development (stage 6), the ring meristem begins to form as a ridge around the center of the flower. At this stage, the internal fourth-whorl organ is stem-like rather than carpelloid in MF. A total...
In filowers with moderate to severe third whorl phenotypes, carpel development is also altered (Figure 5). The tobacco gynoecium is composed of two fused carpels delineated by the seam that divides...Puzzle box,a tobacco line with flowers that mix floral and inflorescence characteristics. Trull...
