Greenflies use the phloem because it is a nutrient-rich tissue in plants that contains sugars and other essential compounds that they need for their diet. The phloem sap is easily accessible and provides a ready source of energy for greenflies to feed on. Additionally, greenflies have specialized mouthparts that are adapted for piercing and sucking fluids from the phloem.

Why greenflies feed by sticking their hollow tube like mouth parts into the phloem of a plant stem?
Greenflies feed by inserting their mouthparts into the phloem because the phloem sap contains nutrients, such as sugars and amino acids, that the greenflies need for energy and growth. By tapping into the phloem, they can access these essential nutrients directly.
What is called the food conducting tissue of a plant?
The food conducting tissue of a plant is called phloem. Phloem is responsible for transporting sugars and other organic nutrients produced by photosynthesis throughout the plant.
Is the xylem or the phloem closer to the cortex?
The phloem is closer to the cortex in a plant stem.
What are the two different types of vascular tissue?
Phloem and xylem are the two main types of vascular tissue found in plants. Xylem is the tissue that mainly carries water, and a few minerals, in the system. Phloem is the tissue that carries photosynthetic materials through the plant.
What is the name of the tissue that contains seive tubes?
Parenchyma cells in "phloem tissue"
What part of the leaf do greenfly pierce?
A greenfly or aphid as it is know scientifically feed from plant stems or leaves using its mouth which contains a slender tube that has two stylets down either side of the tube. A labium that is shaped like a sheath encloses the tube and when not in use holds it horizontally beneath the thorax. When feeding this labium shortens and bends as the central tube with its stylets pierce the epidermis of the leaf or the stem,
Do aphids feed on the phloem part of a plant?
Yes, aphids feed on the phloem sap of plants by using their specialized mouthparts to pierce the phloem vessels and extract the sugary sap. This feeding behavior can weaken the plant and potentially transmit diseases.
Is a greenfly a mammal or reptile?
A greenfly is an insect.
Are a greenfly a carnivores?
A Greenfly is a sap sucker, and not a carnivore.
What kind of plant uses xylem and phloem for their transportation system?
All plants use xylem and phloem vessels.
What is the scientific name for greenfly?
The scientific name for greenfly is Aphid
Why are there so many greenfly around?
Greenfly, also known as aphids, are attracted to plants because they feed on sap. They reproduce rapidly, which can lead to large populations in a short amount of time. Additionally, they are attracted to the chemical signals emitted by plants when they are stressed or damaged.
Why greenflies feed by sticking their hollow tube like mouth parts into the phloem of a plant stem?

Does a greenfly have back bone?
no
What eats greenfly?
ladybirds
Compair transport of substances in xylem and phloem?
through xylem, water flows. through phloem, mineral nutrients get passed through xylem - most of it's components are dead except xylem parenchyma phloem - all of it's components are living except phloem fibres
Can greenfly's kill a rabbit?
Yes
