The cabbage inflorescence, which appears in the plant's second year of growth, features white or yellow flowers, each with four perpendicularly arranged petals. Cabbage seedlings have a thin taproot and cordate (heart-shaped) cotyledons. The first leaves produced are ovate (egg-shaped) with a lobed petiole.
Morphologically, an inflorescence is the modified part of the shoot of seed plants where flowers are formed on the axis of a plant. The modifications can involve the length and the nature of the internodes and the phyllotaxis , as well as variations in the proportions, compressions, swellings, adnations , connations and reduction of main and ...
ABC model of flower development guided by three groups of homeotic genes.. The ABC model of flower development is a scientific model of the process by which flowering plants produce a pattern of gene expression in meristems that leads to the appearance of an organ oriented towards sexual reproduction, a flower.
Brassicaceae (/ ˌ b r æ s ɪ ˈ k eɪ s iː ˌ iː,-s i ˌ aɪ /) or (the older) Cruciferae (/ k r uː ˈ s ɪ f ər i /) [2] is a medium-sized and economically important family of flowering plants commonly known as the mustards, the crucifers, or the cabbage family. Most are herbaceous plants, while some are shrubs. The leaves are simple ...
Matthiola incana is a species of flowering plant in the cabbage family Brassicaceae. Common names include Brompton stock, common stock, hoary stock, ten-week stock, and gilly-flower. [2] The common name stock usually refers to this species, though it may also be applied to the whole genus Matthiola.
In flowering plants, rosettes usually sit near the soil, but they can also be at the top of an otherwise naked branch or trunk. Their structure is an example of a modified stem in which the internode gaps between the leaves do not expand, so that all the leaves remain clustered tightly together and at a similar height.
The function of these flowers is to specialize, within a group of flowers that are perfect, in attracting pollinating insects to the inflorescence. Such flowers, called neutral or asexual , are usually arranged on the periphery of the inflorescence and can be observed, for example, in many species of the compositae family, such as the daisy ...
