xylem, plant vascular tissue that
conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support
. Xylem tissue consists of a variety of specialized, water-conducting cells known as tracheary elements.
Which of the following describes the role of phloem in a vascular plant apex?
-Phloem:
transports sugars from leaves or storage tissues to other parts of the plant
.
Do vascular plants have xylem?
Vascular plants (tracheophytes) differ from the nonvascular bryophytes in that they possess
specialized supporting and water-conducting tissue
, called xylem, and food-conducting tissue, called phloem.
What is the most important job of a vascular plant?
Compactly, vascular plants are those plants that contain vascular tissues such as xylem (important for
transporting water
) and phloem (essential for transporting minerals and nutrients).
What is the role of phloem in a vascular plant?
Phloem is the vascular plant tissue
responsible for the transport and distribution of sugars produced by the photosynthesis
.
Which of the following best describes the vascular system in plants?
Which of the following describes the vascular system of a typical plant? …
It transports nutrients throughout the plant
. It is made up of xylem and phloem.
What is the purpose of the vascular system in a plant?
The two essential functions performed by the vascular system, namely
the delivery of resources (water, essential mineral nutrients, sugars and amino acids) to the various plant organs and provision of mechanical support
are next discussed.
What are two examples of vascular seedless plants?
Seedless vascular plants include,
ferns, horsetails, and club mosses
. Ancient seedless vascular plants grew very tall. For example, club mosses grew to 40 m tall in ancient forests! Today, ferns, horsetails, and club mosses are usually much smaller.
What are the 2 types of vascular plants?
Vascular plants include the
clubmosses, horsetails, ferns, gymnosperms (including conifers) and angiosperms (flowering plants)
. Scientific names for the group include Tracheophyta, Tracheobionta and Equisetopsida sensu lato.
Why are vascular plants successful?
Explanation: Vascular plants are successful
due to better transportation for water, nutrients and reproduction
. The xylem and phloem of the vascular bundles allow for distribution of water and food to all parts of the body. This structures allow vascular plants to colonize farther inland.
What is a vascular plant answers?
Vascular plants are
plants found on land that have lignified tissues for conducting water and minerals throughout the body of the plant
. Non-vascular plants are plants mostly found in damp and moist areas and lack specialized vascular tissues. Vascular plants are also known as tracheophytes.
What are the 3 main parts of a vascular plant?
The three primary parts of the plant’s vascular system are
the xylem, phloem and cambium
.
What are the features of vascular plants?
- Roots. The stem of the plant is behind the derivation of the roots which are the group of simple tissues. …
- Xylem. The xylem is a tissue that supplies water throughout the parts of the plant. …
- Phloem. The phloem is known as the plant’s food supply system. …
- Leaves. …
- Growth.
What is the main function of xylem and phloem?
Xylem tissue
transports water and nutrients from the roots to different parts of the plant
, and also plays a role in structural support in the stem. Phloem tissue transports organic compounds from the site of photosynthesis to other parts of the plant.
What are some of the functions of vascular tissue in seedless plants?
- Xylem transports and stores water and water-soluble nutrients in vascular plants.
- Phloem is responsible for transporting sugars, proteins, and other organic molecules in plants.
- Vascular plants are able to grow higher than other plants due to the rigidity of xylem cells, which support the plant.
Why is xylem dead and phloem alive?
Water transport is also accomplished through physical forces and does not necessitate the use of energy. Except for phloem fibres,
all phloem components are alive
. Because food is transported by active transport, which requires energy, the majority of phloem parts are alive and not dead like Xylem.
