Transporting Materials In Plants
First we must revisit pages 184 and 185 to make sure we understand how plants
rid themselves of waste, then, in the next lesson, we will see how this “waste” can move
through certain plants. Recall what transpiration means, and define it here
________________________________________________________________________
_______________________________________________________________________.
Waste in plants is made from cellular activity (more on this in two lessons). In most
plants, this waste is first stored in an organelle called the ________________________.
It is then transported up a plant to the leaves, and released through tiny holes in the leaves
called ______________________. Remember, a lot of the “waste” produced by plants is
the goodies animals need to survive. What are these goodies?
Okay, on to lesson 5 of this unit, and learning more about the amazing,
miraculous plant world. First, use the space below to draw a picture of a plant. Make it a
bush, tree, or flowering plant, and label the three main parts of all these types of
(vascular) plants. Leave a bit of space to come back and add a few things after we finish
this lesson. If you have time, make it pretty.
BE SURE TO READ THESE TWO PAGES FIRST, THEN FILL IN
BLANKS
Nonvascular plants lack true ___________________, __________________, and
______________________. These types of plants, which include _______________,
absorb water and nutrients from their surroundings. The water carries everything from
cell to cell directly, and this limits how ___________ these types of plants can grow.
Vascular plants, like trees, contain _________________ _____________________,
which supports a plant and transports ________________ and __________________
throughout the plant. There are two types of vascular tissue. They are ____________
and ________________. ____________________ carries water and nutrients from the
roots up to other parts of the plant. The “x” in xylem sounds like a “z” and so the word
sounds like zylem. Using this, “zy-” rhymes with high, and the xylem brings goodies up
or high in the plant. _________________________ carries food made in the leaves to
other parts of the plant. The “ph-” in phloem makes the “f” sound and so the word
sounds like “flowem”. Low rhymes with flow and these vascular tissue transport food
down, or low, the plant. This is just a way to remember which way these vascular
___________ transport materials in a plant. All three main parts of a plant contain these
tissues.
True or False. Xylem and phloem tissue are found in nonvascular plants.
Roots and root hairs __________________ water and nutrients from the _______.
_______________ cells take these goodies up and into the stem. A _________________
pushes deep into the soil, and may store food for a plant. It also ________________ the
plant to the ground to survive. ____________________ roots are more thin and spread
out just below the surface of the soil. These roots form a mat which can ___________
soil in place and absorb water from a large area. The xylem and phloem tissues in roots
___________________ with these same tissue in the stems. This forms a sort of
___________________________ in the plant to allow the transport of needed materials.
In trees, vascular tissue is gathered in ______________. You may have seen this pattern
in a tree that has been cut. Stems also provide _________________________ for a plant,
so it can grow high and bring the leaves closer to our energy source, the sun.
Leaves of plant are the makers of food. They contain organelles called
_________________________, which contain a green pigment that _________________
light energy. Leaves use __________________ _____________________,
__________________, and _________________ to make sugar. _______________, like
found in the human circulatory system, transports the sugar from the leaves to each cell in
the plant. They then connect to the vascular tissue called phloem, and is now in the tree’s
pipeline or transport system.
