Like bacteria, plant cells have cell walls, and contain organelles such as chloroplasts in addition to the organelles in other eukaryotes.

Parenchyma cells have thin, permeable primary walls enabling the transport of small molecules between them, and their cytoplasm is responsible for a wide range of biochemical functions such as nectar secretion, or the manufacture of secondary products that discourage herbivory.

Xylem cells are elongated cells with lignified secondary thickening of the cell walls.

Xylem tracheids are pointed, elongated xylem cells, the simplest of which have continuous primary cell walls and lignified secondary wall thickenings in the form of rings, hoops, or reticulate networks.

Vessel members are hollow xylem cells aligned end-to-end, without end walls that are assembled into long continuous tubes.

Antibiotics such as penicillin commonly target bacterial cell wall formation ( of which peptidoglycan is an important component ) because animal cells do not have cell walls.

* Secretory vesicles hold the enzymes that are used to make the cell walls of plants, protists, fungi, bacteria, and Archaea cells as well as the extracellular matrix of animal cells.

The bees often smooth the bark surrounding the hive entrance, and the cavity walls are coated with a thin layer of hardened plant resin ( propolis ).

The return of the British force to Boston following the search operations at Concord was subject to constant skirmishing, using partisan forces gathered from communities all along the route, making maximum use of the terrain ( particularly trees and stone field walls ) to overcome the limitations of their weapons-muskets with an effective range of only about 50 – 70 metres.

Influenced by the events of the Fronde, Louis XIV rebuilt the area around the Bastille, erecting a new archway at the Porte Saint-Antoine in 1660, and then ten years later pulling down the city walls and their supporting fortifications to replace them with an avenue of trees, later called Louis XIV's boulevard, which passed around the Bastille.

They are as high as the top of the walls and owe their charm to the shade of many tall trees.

Frontiersmen often carved messages on trees or wrote their names on cave walls, and Boone's name or initials have been found in many places.

Other shapes such as cordons, espaliers and fans offer opportunities for growing trees two dimensionally against walls or fences, or can themselves be trained as barriers.

The climbing varieties are valued for their ability to scramble up walls, fences and other structures, and also to grow through other plants, notably shrubs and trees.

It is an seasonal climbing plant, growing high where suitable surfaces ( trees, cliffs, walls ) are available, and also growing as ground cover where there are no vertical surfaces.

However, like willows, poplars have very vigorous and invasive root systems stretching up to 40 m from the trees ; planting close to houses or ceramic water pipes may result in damaged foundations and cracked walls and pipes due to their search for moisture.
