Each plant may be a few inches tall, and pine-cone-shaped or cylindrical. The plant above ground is almost entirely made up of its inflorescence, a tightly packed column of thick cup-shaped flowers. The groundcone produces haustoria which penetrate the roots of its host and provide it with water and nutrients.
The ground tissue of plants includes all tissues that are neither dermal nor vascular. It can be divided into three types based on the nature of the cell walls. This tissue system is present between the dermal tissue and forms the main bulk of the plant body. Parenchyma cells have thin primary walls and usually remain alive after they become ...
Common names include plant bugs, leaf bugs, and grass bugs. It is the largest family of true bugs belonging to the suborder Heteroptera ; it includes over 10,000 known species, and new ones are being described constantly.
Some insects create their own microhabitats by forming a plant structure called a gall, made up of plant tissue, but controlled by the insect. A gall acts as both a habitat and food source for the maker of the gall. The interior of a bedeguar gall is formed from the bud, and is composed of edible nutritious and structural tissues.
Dendrosenecio is a genus of flowering plants in the sunflower family. [3] [4] It is a segregate of Senecio, [1] in which it formed the subgenus Dendrosenecio. [1]Its members, the giant groundsels, are native to the higher altitude zones of ten mountain groups in equatorial East Africa, [5] where they form a conspicuous element of the flora.
The tallest inflorescence of an Amorphophallus titanum was recorded at Meise Botanic Garden, Belgium, on 13 August 2024. It measured 322.5 cm from the tuber. Its tuber is the largest known, typically weighing around 50 kg (110 lb). [4]
Giant swamp taro contains toxins which must be removed by long cooking. It may be field stored in the ground for very long periods – up to 30 years or more – and accordingly has traditionally been an important emergency crop in times of natural disaster and food scarcity. [3] The cooked corms can be dried in the sun and stored for later use ...
As a result of fertilisation, the female gametophyte produces sporophytes. A few species of Selaginella such as S. apoda and S. rupestris are also viviparous; the gametophyte develops on the mother plant, and only when the sporophyte's primary shoot and root is developed enough for independence is the new plant dropped to the ground.
