Why don't some insects that are parasitic on plants obtain their food from xylem?

The xylem and phloem tissue are collectively known as vascular tissue. The main responsibility of vascular tissue is to transport water and food, as well as other nutrients, throughout the body. The xylem carries water from the roots up to the leaves. The leaves perform photosynthesis, and the sugars synthesized is then moved throughout the body through the phloem. The reason why insects feed off these tissues is to gain access to the foods and water inside.

∙ 10y agoIn plants, xylem transports raw nutrients up the stalk of the plant; the nutrients are then processed by the chlorophyll in the leaves...making energy in the form of ATP, before continuing down to the roots through the phloem. The roots have no chlorophyll, and therefore cannot make ATP through the process of photosynthesis...they depend on the leaves to do this before the phloem performs the task of transport. Therefore, the nutrients contained in the phloem are more bio-available than the ones in the xylem.

What do you understand by parasitic plant?
the plants that obtain there food by totally depending on host eg-cuscuta
Do mushroom and floating plants have xylem tissues?
Mushrooms/fungi are not plants. Floating plants do have xylem. it has tissue
What fibers surround the xylem and phloem tissues?
The xylem and the phloem tissues are found in plants. Bast fibers surround the xylem and the phloem tissues in plants.
Do vascular plants have xylem and phloem?
Yes, but some plants lack certain types of xylem and phloem cells such as vessel elements and tracheids. Tracheids have been lost in Wolffia, an aquatic plant, and vessels are not present in all conifers.

Xylem have what?
Vascular plants have xylem
Do we have plant which do not prepare it own food?
Most plants are autotrophic, meaning that they are able to produce their own food through photosynthesis. All these plants need are photons provided by sunlight, water, and carbon dioxide. There are, however, some plants that are heterotrophic; they obtain their food through ways other than photosynthesis. Most of these plants, such as carnivorous plants like the Venus fly trap, are still capable of producing their own food. Parasitic plants are the exceptions. While they do have the chloroplasts needed to perform photosynthesis, they do not have roots, which are used to obtain water and nutrients. One example of a parasitic plant is mistletoe. Mistletoe sends its "suckers" into the vessel of its host's xylem cells, to draw out raw sap. The plant then uses this material to perform photosynthesis as other plants do. While they are still able to prepare their own food, parasitic plants are dependent on other organisms for the raw materials.

What plant have xylem and phloem tube?
Vascular plants. Xylem and Phloem are the vascular system of plants. If you compare it with humans, they're the blood vessels...sort of Xylem transports water, Phloem transports nutrients
What is xylem flow in plants?
Xylem transports water throughout the plant.
What are the tubes called in plants the carry water into the plant?
This is the vascular tissue xylem.
