What are the names for bugs that eat plants?
Plant-eater and plant-eating bugs are names for bugs that eat plants. The bugs in question also may be called herbivores ("plant eaters"). They tend to cause the most damage when they remove the plant's internal fluids, such as the phloem or the xylem.
How do vascular plants' xylem and phloem compare to an animals' arteries and veins?
Xylem, phloem, arteries and veins are all specialized transport systems that serve a unique but similar function in their respective organisms. Arteries and veins make up the circulatory system of many animals and are the primary mechanism for transporting nutrients and vital compounds throughout a living organism. The arteries are specialized in the transport of oxygenated blood away from the heart while veins return blood without their oxygen back to the heart to restore the cycle. Along the way, various compounds are dropped off and picked up at various cells. While arteries and veins are an all encompassing system for transporting anything, xylem and phloem are even more specialized to only work in transporting certain materials. Phloem is specialized in the transport of nutrients, particularly sugar, throughout a vascular plant, while xylem is almost exclusively for water. Wheres arteries and veins require the pumping of a heart to flow, xylem and phloem depend on basic physical principles. Phloem utilizes the change in concentration between sources of nutrients and sites in need of nutrients to literally draw the nutrients where they are needed. Likewise, xylem depends on osmosis and a difference in pressure at the roots and the leaves to draw water up and through the plant.
How are ferns like nonvascular and vascular plants?
Ferns are vascular plants. Vascular plants are non-seeded plants meaning you do not have to plant a seed for them to grow. Ferns grow by air borne spores. Ferns also can be kept in a drier climate due to them being vascular. There aren't similarities between vasucular and non vascular plants.
What are the traits of conifers?
It is a non flowering plant.Conifers are also known as EVERGREEN PLANTS because they remain green throughout the whole year.Conifers are found in colder regions and hilly areas.Conifers have prominent roots and stem.there leaves are long,narrow and needle like.These plants produce seeds but these are not enclosed in fruits i.e., they are naked.Seeds of conifers are present in the form of cone.Vascular tissues i.e.Xylem and Phloem are present in conifers.These are some of the traits of the conifers.
How can be a good green ambassador?
Don't waste water, save plants , use recycled materials for daily uses, keep your environment neat and tidy, save electricity, don't waste food.
Which tubes in a plant carry glucose?
Carbohydrates are moved about plants in the sieve tubesof the phloem.This movement of materials from one part of a plant to another is called translocation. Carbohydrate is normally translocated as sucrose. If you inject glucose or fructose into a plant, it will probably be converted into sucrose before translocation.
What are The types of vascular tissue inside plants that transport energy from photosynthesis and materials from the roots to the rest of the plant are called?
The types of vascular tissues are called xylem and phloem. Phloem cells transport energy from photosynthesis and xylem transport materials from the roots to the rest of the plant. These plants are called autotrophs.
Is phloem in a plant or in an animal?
Phloem is found in plants.
Do Vascular plants have phloem?
Phloem as well as xylem
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.
The driving force for the movement of materials in the phloem of plants is?
Phloem ~ Pressure Flow Theory The phloem tissue moves products of photosynthesis by active transport. The flow of materials in phloem is an active process that requires energy. The mechanism of flow is driven by an osmotic pressure gradient, generated by difference in sugar and water concentrations. Just remember photosynthesis= water + sugar water= osmosis sugar=gradient
What fibers surrounds the xylem and phloem?
The xylem and the phloem tissues are found in plants. Bast fibers surround the xylem and the phloem tissues in plants.
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
How do plants move the materials?
They have tubes in them called the xylem and phloem tubes. The xylem tubes carry water and mineral salts from the roots to all parts of the plant. The phloem which carry food from the leaves to all aprts of the plant.
Which is vascular tissue in plants?
Phloem
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.
What distinguishes xylem and phloem from other tissues?
Xylem and phloem are vascular tissues. They are tissues that form tubes in plants. Xylem carries water and minerals contained in water that is drawn up from the ground through the roots. Phloem carries food produced in leaves down and up to other parts of plants. In trees, the phloem is located just inside the bark. It is a fairly narrow region. The part of trees called wood is the xylem. A layer called the vascular cambium is located between the xylem and phloem. It produces xylem to the inside and phloem to the outside. Growth rings in tree trunks are xylem. Plants like mosses, liverworts and horn worts don't have vascular tissues. Water, minerals, and food move around these plants very slowly. The movement is from one cell to another then another, and so on. Nonvascular plants are small and must grow in moist places. Vascular plants are larger because materials can move around in them quickly.
