More broadly, these patterns of Orobanche bacterial diversity and community assembly exhibit intriguing parallels with the microbiota of eukaryotic parasites of animal hosts (e.g. The typical nematode shape is a long and slender worm-like animal, but often the adult animals are swollen and no longer even resemble worms ( Figure 2 ). Answer (1 of 7): Neither. The survival strategy of parasitic plants is based on the rapid penetration of host plant tissue and the subsequent formation of physical connections (haustoria) with the host's vascular tissue. (ii) Saprophytic plants cannot grow without the host plant. Parasitic plants attach and feed off other plants using a parasitic structure called a haustorium. It's sometimes known as Cuscuta, which is its genus name. The parasite is only visible when the buds appear. Pitcher plants are one kind of carnivorous plant which uses their altered leaves to attract insects and animals and eat them. The haustorium is a specialised multicellular organ homologous to a root, which penetrates a host, makes a vascular connection, and facilitates the transfer of nutrients and other molecules. Because Striga requires host-generated strigolactones to germinate, the identification of selective and potent strigolactone agonists could help control these noxious weeds. general linear model (GLM) with number of pollen The nectar of the host plant is usually more concen- grains as the dependent variable and pollen identity trated than that of the parasite: in C. scabiosa, percent (host or parasite) and position of pollen on the insect's sugar . Dodder is a parasitic plant that pulls nutrients from the host plants it wraps itself around.

C) These enzymes are needed to release nitrogen from dead plant material in colder environments. They all have a special root, called a haustorium, which is used to pierce the host and reach its xylem or phloem. The physiological conduit helps in redirecting resources from the host plant into the parasite . Langsdorffia flowers, which is a parasitic plant, consists of flashy flowers and suckers.
