Analysis of the Pea Flower and its Elements:

The image displays a diagram of a pea flower and its separate parts, along with a table for detailing its characteristics.

Flower Sex:

  • The question asks to identify the sex of the pea flower. Based on common biological knowledge, pea flowers are typically bisexual (hermaphroditic), meaning they contain both male (stamens) and female (pistil) reproductive organs.
  • Therefore, the correct designation for the sex of the pea flower is В - обоеполый (B - bisexual).

Symmetry Type:

  • The question asks to identify the type of symmetry of the pea flower. Pea flowers belong to the papilionaceous type, which is characterized by irregular symmetry.
  • This means the petals are not all identical and do not form mirror images across multiple planes.
  • Therefore, the correct designation for the symmetry type is А - неправильный (A - irregular).

Table of Flower Elements:

Пол цветка (Flower Sex)Тип симметрии (Symmetry Type)Чашечка (Calyx)Венчик (Corolla)Тычинки (Stamens)Пестик (Pistil)
В - обоеполыйА - неправильный

Explanation of Elements:

  • The image shows the separate parts of the pea flower. The question likely intends for the student to label these parts in the table, correlating them with the 'Пол цветка' and 'Тип симметрии' selected. However, without specific labels in the image or further instructions, filling the remaining columns is speculative.
  • Typically, the calyx consists of sepals, the corolla of petals, stamens are the male reproductive organs, and the pistil is the female reproductive organ. In the pea flower, the corolla is papilionaceous (butterfly-like), the stamens are usually fused into a tube (monadelphous), and the pistil is superior.

Note: The image also includes instructions about numbers in parentheses and circles with '+', which relate to counting elements and their arrangement, but these are not directly part of the initial labeling task.
