NEET BIOLOGY

Detailed explanation-1: -Complete answer: Axile type of placentation is seen in lemon and tomato. In this type of placentation, the ovary is partitioned into two or more chambers by septa. The placenta is formed in the central region where all the septa intersect or meet and therefore an axle column bearing ovules is formed.

Detailed explanation-2: -Hence, the correct answer is ‘Axile’

Detailed explanation-3: -Definition. A type of ovule arrangement in which the ovules arise from placental tissue derived from the apices of the septa of a locule. In this type of placentation the apices of the septa are fused or in very close proximity to one another.

Detailed explanation-4: -Axile placentation occurs in syncarpous pistils. The ovary is partitioned into two or more chambers. Placentae occur in the central region where the septa meet so that an axile column bearing ovules is formed e.g., shoe flower (pentalocular), lemon (multilocular), etc.

Detailed explanation-5: -The placentation is axile when there are septa which divide the ovary into two or more locules. The ovules are attached along the central axis, in the inner angle formed by the septa. Parietal placentation: there is no septum, so that the ovary is unilocular.
