Define the following(a) Flower (b) Actinomorphic (c) Heterophylly
(d) Phyllotaxy (e) Hypogynous (f) Parthenocarpic fruit
(g) Venation.
Answers
Answer:
(a) FLOWER:It is a specialized condensef shoot meant forsecual reproduction.
(b)Actinomorphic: Flower which can be divided into two equal vertical halves by any vertical plane padsing through the centre is called actinomorphic ( radial symmetry). Eg: mustard datura chilli
(c) HETEROPHYLLY: Marked changes in leaf morphology induced by environmemtal conditions ; the ability to displace such changes.
(d)PHYLLOTAXY: The arrangement of leaves on the stem or branches. The purpose of phyllotaxy is to arrange leaves in such a way that all of them are exposed to light properly.
(e ) HYPOGYNOUS: Gynoecium occupies the highest position while the other floral parts are situated below it. The ovary is described as superior.
(f) PARTHENOCRPIC FRUIT: Development of fruit without fertilization. It resembles a fruit but it id seedless.
(g) VENATION: The arrangement of veins and veinlets in the leaf lamina is called venation.
The definitions of the given terms in the question are described below :
(a) Flower
The structure of the plant that has the role in reproduction is termed as flower. It is considered as the organ of reproducing of the plants.
(b) Actinomorphic
It is a type of symmetry in which a flower or a blossom when divided radially results in two halves that are similar.
Examples : Chilli, Mustard, etc.
(c) Heterophylly
It is the condition where various kinds of leaves are present on the same shoot or different stem of the same plant.
(d) Phyllotaxy
It is the type of leaf arrangement on the stems.
(e) Hypogynous
In such flowers, the gynoecium is located at great height while other sections are located below it.
(f) Parthenocarpic fruit
Such fruits which develops without undergoing the process of ovarian fertilization are called parthenocarpic fruits.
(g) Venation
It is the pattern of how the veins as well as veinlets are arranged in the leaf's lamina.
