Basic Photosynthesis
Fill in the blanks of the diagram with the following words:
 Water (H2O)
 Carbon Dioxide (CO2)
 Light Energy
 Food (C6H12O6)
 Oxygen (O2)
Questions:
1. Which two types of atoms (Carbon, Hydrogen, or Oxygen) enter the plant but do not
leave the plant?
2. Out of the two atoms that you selected in question 1, which one do you think allows the
plant to grow?
Explain your reasoning:
Photosynthesis
Photosynthesis is a process unique to the pant world. Photo means “light” and synthesis means
“putting together”. Through this process, plants are able to make their own food. Use the terms in the
word box to complete each sentence.
Photosynthesis
Oxygen
Glucose
Chloroplast
Carbon Dioxide
Cellulose
Carbohydrates
Sunlight
Leaves
Water
Chlorophyll
1. Water, carbon dioxide, and ________________________________ are the three
ingredients needed for photosynthesis to occur.
2. Through photosynthesis, plants convert these ingredients into
________________________________, a food used by the plant.
3. ________________________________ is the material in green plant cells that trap energy
from the sun.
4. The plant take in a gas called ________________________________ from the air.
5. Chlorophyll is found in the ________________________________, structures within the
cell where photosynthesis will take place.
6. ________________________________ is a material the plant takes up through its roots
and stems.
7. During photosynthesis, ________________________________ is a waste product
released by the plant into the air.
8. Plants produce more glucose than they need. The excess glucose is stored by the plant as
________________________________ or starches.
9. Plants also change glucose into ________________________________, the structural
material used in their cell walls.
10. While chlorophyll is found in most above-ground parts of green plants, most
photosynthesis takes place in a plant’s ________________________________.
11. In many regions, there is not enough sunlight or water during winter for
________________________________ to occur.

Journal Title: Angiosperm Stem Types and Parts
Woody Stem
Label the following cross section of a woody stem. Use the woody stem diagram provided to help
label the parts. NOTE: The cambium is where new xylem and phloem cells form each year.
Questions:
1. Using the actual woody stem cross section, try to locate the five parts of the stem labeled
above.
2. How old is your actual woody stem cross section (count the rings)? ___________________
3. Which do you count to determine the age of the tree? (xylem or phloem) ______________
4. Why is the spring xylem thicker than the summer xylem? ___________________________
Herbaceous Stem

Question:
Is the stained vascular tissue in the
celery stalk the xylem or phloem?
Explain why.

Leaves
Color and label the following cross section of a leaf. Use the word bank and textbook to help label the parts.
Epidermis
Guard cell
vein
palisade layer
stoma
spongy layer
cuticle
Questions:
1.
What part of the leaf labeled above contains the xylem and the phloem? _________________________
2.
What is the function of the stomata? ______________________________________________________
3.
In most leaves, the stomata are found only on the lower epidermis. Why do you think it is not a successful
adaptation to have the stomata on the upper epidermis (top side of the leaf)?
