2. Lesson Objective The student willcompare structures in plants (roots, stems, and 
leaves) that serve functions in the growth of vascular plants. Subobjective 1: The student will identify the function of the phloem 
and the xylem, and the part they play in the transportation of sugar, 
water, and minerals in a vascular plant. Subobjective 2: The student will compare two types of roots and the 
function of the roots. Subobjective 3: The student will explain the process of 
photosynthesis and its relationship to the growth of plants.

3. Vascular plants are: plants that have special tissues for transporting water, minerals, sugars and other nutrients. Vascular Plants water and minerals Phloem transports sugars, nutrients, and 
other minerals throughout the 
plant to keep it healthy and 
growing Xylem transports water and minerals 
upwards toward the leaves from the 
roots

4. Vertical Cross Section of a Stem Identify the xylem and the phloem. Click above the line to check your answer. water and food 
(sugars) water and 
minerals cells have end 
walls with 
perforations no end walls 
between cells two-way flow flows one way 
only - up phloem xylem

5. Horizontal Cross Section of a Stem Identify the xylem and the phloem. Click above the line to check your answer. xylem tubular cell 
tissues that 
transport 
water 
upward 
toward the 
plant phloem tubular cell tissues 
that transport 
sugar and nutrients 
throughout the

6. Roots: are the mouth of the plant absorb water and minerals from soil anchor the plant store food Slide out pictures to reveal the information.

7. Two Common Types of Roots Look at the pictures and talk about what you think the root system 
would be named and what it would do. Then click the boxes.

9. Leaves Leaves are the food making factories of green plants. Look at the pictures and describe the leave based on the 
picture and name, then click the box for the answer. Simple Leaf Made of a single leaf blade Compound Leaf Made up of separate leaflets Read about leaves - Click on link

10. Things You Should Know About Leaves Leaves have veins that carry water 
and nutrients within the leaf. Leaves catch light. Leaves have openings to allow 
water and air to come and go. Leaves are where the food making 
process called photosynthesis occurs. Photosynthesis Carbon dioxide and water in 
the presence of chlorophyll 
and light energy are 
changed into glucose (a 
type of sugar). This sugar is 
the food source for plants. light energy carbon dioxide and water chlorophyll in leaves water and nutrients

11. Now that you understand the function of different parts of a plant, 
how a plant produces its food, and how the food flows through the 
plant, click on the linkbelow to watch a video of plants growing. After viewing the video, write an essay about the video and how the 
transportation of food in a plant helps it to grow.
