What type of placentation is seen in sunflower?
basal placentation
The type of placentation where the ovules are attached to the base of the ovary is called basal placentation. Plants like marigold and sunflower shows basal placentation.
Which type of placentation is found in pea?
marginal placentation
Sweet pea shows marginal placentation. In marginal placentation, a ridge is formed by the placenta along the ventral suture of the ovary. The development of ovules takes place on the ridge. Thus, two separate rows are formed.
Is marginal placentation found in pea?
Marginal placentation occurs in a monocarpellary, unilocular ovary. Plants belonging to Fabaceae family like Gram, Pea, Arhar, Sunhemp, Moog, Lupin bear Marginal placentation.
Where is basal placentation found?
Basal placentation occurs in Poaceae. In plant species, placentation develops where the ovules are connected to the inside of the ovary. The ovules inside the ovary of the flower are attached to the ovary by funiculi, which is similar to the umbilical cord of the plant.
What is basal placentation give one example?
4. Basal placentation: A single ovule is linked to the placenta, which develops at the base of the ovary. Marigold is an example.
What is marginal placentation example?
(A) Marginal placentation: The ovary in which the placenta forms a ridge along the ventral suture of the ovary and the ovules develop on two separate rows is known to have marginal placentation. e.g peas.
Is sunflower a basal?
Sunflower exhibits basal placentation in which the placenta develops at the base of ovary and a single ovule is attached to it.
What is the example of free central placentation?
– Ovary is one chambered and the placenta bearing the ovules develops all around the central axis. Example: Dianthus, Stellaria. The Dianthus is an example of a free central placentation.
What type of placentation is found in tomato?
Axile type
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.
Which of the following has marginal placentation?
Ovules are borne on this ridge forming two separate rows. Marginal placentation is the characteristic property of family Leguminosae or Fabaceae. Among the options given in the question, the plants having marginal placentation are Gram, Arhar, Sunhemp, Moong and Lupin.
What is the placentation of mango?
Placentation when unilocular parietal, or basal. Ovules in the single cavity 1; pendulous, or ascending; apotropous; with ventral raphe, or with dorsal raphe; non-arillate; anatropous.
Which type of placentation is found in tomato and lemon?
Axile
Hence, the correct answer is ‘Axile‘
What type of placentation is found in cucumber?
Parietal
The type of placentation seen in cucumber is Parietal. Marginal placentation– In marginal placentation, the placenta forms a ridge along the ventral suture of the ovary and the ovules develop on it making two separate rows.
What type of placentation is avocado?
| Type of Placentation | Description | Example |
|---|---|---|
| Free central | Ovules located on the projection from the base of a one chambered fruit | Green pepper |
| Basal | Ovule found on a placenta that arises from the base of the ovary, fruit usually single seeded | Mango, avocado. |
What is placentation in fruits?
In flowering plants, placentation is the attachment of ovules inside the ovary. The ovules inside a flower’s ovary (which later become the seeds inside a fruit) are attached via funiculi, the plant part equivalent to an umbilical cord.
What type of placentation is banana?
Ovary inferior, tricarpellary, syncarpous, trilocular, numerous ovules on axile placentation. The style is simple and filiform.
What type of placentation is coconut?
Specimen H/Coconut: Epicarp and mesocarp separate; Endocarp is hard/stony; One seed; Only one chamber in fruit; Mesocarp fibrous; Parietal placentation.
Which type of placentation is found in primrose?
free-central placentation
Primrose has free-central placentation where the ovules are borne around a central column, which is not connected with the ovary wall by any septum.
Which type of placentation is found in china rose?
axile placentation
China rose, lemon and tomato have axile placentation, i.e., the placenta is located on a central column; partitions from the central column to the ovary wall create chambers that separate the placentae and attached ovaries from each other.
What is parietal type of placentation?
said to be axile, as in china rose, tomato and lemon. In parietal placentation, the ovules develop on the inner wall of the ovary or on peripheral part. Ovary is one-chambered but it becomes twochambered due to the formation of the false septum, e.g., mustard and Argemone.
