Question

Placentation found in Caryophyllaceae is
a)Axial
b)Basal
c)Parietal
d)Free central
d)Marginal

Answer 1

Hint: The ovary is the most important part of the carpel as it contains ovules that develop into seeds after fertilization. There are several locules present inside the ovary as different chambers. inside locules, a special tissue is present called the placenta from which the ovary develops. Placentation is the arrangement of the placenta in the ovary.

Complete answer:
The Caryophyllaceae are spices or once in a while subshrubs containing around 75 genera and 2,000 species further portrayed by p-plastids and normally swollen hubs. The leaves are basic, almost consistently inverse and decussate, and are estipulate or now and then have scarious stipules.
It comprises two or five carpels; syncarpous. The styles are free. The ovary is prevalent and unilocular; the ovules are many, campylotropous, and masterminded on a focal segment. The placentation is free-focal which is generally normal for the family. The quantity of carpels relates to the number of styles and marks of disgrace. In Stellaria, the quantity of carpels is diminished to three.
The seeds are little and endospermic. The incipient organism is bended in the endosperm. Once in a while the funicle is obvious. They are scattered by the sensor system.

Additional Information: The blossoms are actinomorphic and generally promiscuous. In spite of the fact that the corolla once in a while might be missing, the perianth ordinarily comprises a calyx of 5 connate sepals and a corolla of 5 particularly, often ripped at petals. The gynoecium comprises a solitary compound pistil of 2-5 carpels, as a rule with an equivalent number of styles and with a prevalent ovary that has a solitary locule with various free focal ovules. At times, the ovary is 3-5 locules with axile placentation basally and l-locule with free focal placentation above. The stamens are in a couple of whorls, either rising to or double the number of petals. Infrequently, there might be a solitary basal ovule. The natural product most regularly is capsular.
So the correct answer is 'Free central’.

Note: For the most part, the natural product is a unilocular case, e.g., Stellaria, Arenaria, Spergula, and so forth. Now and again, the natural product might be an achene or a nut, e.g., Herniaria, Dysphania, Scleranthus, and so on.
