Structure of a plant cell. Plant cells are the cells present in green plants, photosynthetic eukaryotes of the kingdom Plantae.Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or ...
Cell fusion is an important cellular process in which several uninucleate cells (cells with a single nucleus) combine to form a multinucleate cell, known as a syncytium. Cell fusion occurs during differentiation of myoblasts, osteoclasts and trophoblasts, during embryogenesis, and morphogenesis. [1] Cell fusion is a necessary event in the ...
Plant reproduction is the production of new offspring in plants, which can be accomplished by sexual or asexual reproduction. Sexual reproduction produces offspring by the fusion of gametes, resulting in offspring genetically different from either parent. Asexual reproduction produces new individuals without the fusion of gametes, resulting in ...
In botany, a bract is a modified or specialized leaf, especially one associated with a reproductive structure such as a flower, inflorescence axis, or cone scale. Bracts are usually different from foliage leaves; they may be of a different size, color, shape, or texture. Typically, they also look different from the parts of the flower, such as ...
G. Raddi [1] Schinus terebinthifolia is a species of flowering plant in the cashew family, Anacardiaceae, that is native to subtropical and tropical South America. Common names include Brazilian peppertree, [2] aroeira, rose pepper, broadleaved pepper tree, [3] wilelaiki (or wililaiki), [4] Christmasberry tree[5] and Florida holly. [6]
A leaf (pl.: leaves) is a principal appendage of the stem of a vascular plant, [1] usually borne laterally aboveground and specialized for photosynthesis. Leaves are collectively called foliage, as in "autumn foliage", [2][3] while the leaves, stem, flower, and fruit collectively form the shoot system. [4]
The history and character of gardens in ancient Egypt, like all aspects of Egyptian life, depended upon the Nile, and the network of canals that drew water from it.Water was hoisted from the Nile in leather buckets and carried on the shoulders to the gardens, and later, beginning in about the 14th century B.C., lifted from wells by hoists with counterbalancing weights called shadouf in Arabic.
A grafted tree showing two differently coloured blossoms. Grafting or graftage[1] is a horticultural technique whereby tissues of plants are joined so as to continue their growth together. The upper part of the combined plant is called the scion (/ ˈsaɪən /) while the lower part is called the rootstock.
