A lampshade is a fixture that envelops the light bulb on a lamp to redirect the light it emits. The shade is often affixed onto a light fixture to reduce the intensity of the light to observers, shield the light from a harsh environment, or for decoration by altering the color or creating shadows.
Magnoliopsida is a valid botanical name for a class of flowering plants. [1] By definition the class will include the family Magnoliaceae , but its circumscription can otherwise vary, being more inclusive or less inclusive depending upon the classification system being discussed.
A flowering Fenestraria rhopalophylla, so named due to the translucent leaf window on the tips of its modified leaf.. Leaf window, also known as epidermal window, [1] and fenestration, [2] [3] is a specialized leaf structure consisting of a translucent area through which light can enter the interior surfaces of the leaf where photosynthesis can occur.
A plant which completes its life cycle (i.e. germinates, reproduces, and dies) within two years or growing seasons. Biennial plants usually form a basal rosette of leaves in the first year and then flower and fruit in the second year. bifid Forked; cut in two for about half its length. Compare trifid. bifoliate
Parts of plant stem Euonymus alata, an example of alate stems Saraca cauliflora, an example of cauliflora Sciadopitys verticillata, an example of a verticillate plant. Accessory buds – an embryonic shoot occurring above or to the side of an axillary bud; also known as supernumerary bud. Acrocarpous – produced at the end of a branch.
The light from the lamp (1.) functions as a detectable change in the plant's environment. As a result, the plant exhibits a reaction of phototropism--directional growth (2.) toward the light stimulus. Auxin distribution controls phototropism. 1. Sunlight strikes the plant from directly above. Auxin (pink dots) encourages growth straight up. 2 ...
Phytomorphology is the study of the physical form and external structure of plants. [1] This is usually considered distinct from plant anatomy, [1] which is the study of the internal structure of plants, especially at the microscopic level. [2] Plant morphology is useful in the visual identification of plants.
Plant classification is the placing of known plants into groups or categories to show some relationship. Scientific classification follows a system of rules that standardizes the results, and groups successive categories into a hierarchy. For example, the family to which the lilies belong is classified as follows: Kingdom: Plantae; Division ...
