The plant is poisonous, containing cardiostimulant compounds such as adonidin and aconitic acid. [42] Aesculus hippocastanum: horse-chestnut, buckeye, conker tree Sapindaceae: All parts of the raw plant are poisonous due to saponins and glycosides such as aesculin, causing nausea, muscle twitches, and sometimes paralysis. [43] Agave spp.
Atropa bella-donna flower. Atropa bella-donna is a branching herbaceous perennial rhizomatous hemicryptophyte, often growing as a subshrub from a fleshy rootstock. Plants can reach a height of 2 m (7 ft) (more commonly 1.5 m (5 ft)), and have ovate leaves up to 18 cm (7 in) long.
First, there is the direct injury they cause to the plants as they feed on the tissues; a reduction in leaf surface available for photosynthesis, distortion of growing shoots, a diminution of the plant's growth and vigour, and the wilting of shoots and branches caused by the insects' tunneling activities.
Mushrooms, molds, and other fungi are not plants, despite similarities in their morphology and lifestyle. The historical classification of fungi as plants is defunct, and although they are still commonly included in botany curricula and textbooks, modern molecular evidence shows that fungi are more closely related to animals than to plants.
The papaya mealybug inserts its stylet into the epidermis of the leaf or the skin of fruit or stem and feeds on the plant sap. At the same time it injects a toxic substance into the plant which results in chlorosis, distortion, stunting, early leaf and fruit fall, the production of honeydew, sooty mould and possibly the death of the plant.

A prefix meaning "two", e.g. bisulcate, having two sulci or grooves. biennial 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
Anamirta cocculus (Marathi: काकमारी) is a Southeast Asian and Indian climbing plant. Its fruit is the source of picrotoxin, a poisonous compound with stimulant properties. The plant is large-stemmed (up to 10 cm in diameter); the bark is "corky gray" with white wood.
This is a toxic plant. At high doses, an extract of the plant exhibited marked damage to all the major organs of the body in both rats and mice. The toxicity appears to depend on the plant organ studied, as well as the season it is harvested, with the bark collected in the monsoon season being the least toxic, and bark in the summer the most.
