In a plant, ____ conducts water and nutrients absorbed from the soil.
phloem
xylem
parenchyma
collenchyma
sclerenchyma
Homework Answers
Answer- Xylem
Explanation- Xylem is dead plant vascular tissue that has specialized water conducting cells known as tracheary elements. These tracheary elements are hollow, narrow and elongated that transports water from one tracheid to another trachied through pit membrane. This xylem transports water and minerals from roots to upward body parts of plant. As xylem is dead tissue it also provide physical support to plant.

QUESTION 1
Which of these statements is NOT correct?
A.
Endodermis requires energy to move nutrients into vascular
cylinder of roots.
B.
Energy is required to make soil nutrients available to
roots.
C.
Plants spend energy to maintain their symbiotic relationship
with soil microorganisms.
D.
Root cells do not spend energy to transfer nutrients from soil
because their movement is powered by transpiration when water
enters the roots.

1. Healthy soil (Links to an external site.) is vital to plant nutrients and to the health of humans. Good soil produces healthy plant life which results in a well-fed animal population. When soil gets polluted the entire food chain suffers; creating a huge number of problems. How does soil pollution affect plant growth? How, then, might the pollution affect humans either directly or indirectly? Research and provide 2 examples. 2. The 40 Fruit Tree. Plants have the impressive ability...

Water is transported upward in a plant through xylem tissue, which consists of cells of 1 mm length and a diameter of 290 µm. The xylem cells are attached to each other to form a channel. To what maximum height can water rise in these xylem channels due to capillarity? For those interested: Confirm this result with a simple experiment: Cut and split the stem of a flower with white petals (e.g., a dahlia or a carnation) and place one...
