Plant Review
1. What are the functions of each plant part? Be sure to list all.
- Leaf – site of photosynthesis
-
Stem – support and transport
-
Root – anchor, absorption
-
Seed – plant embryo, nourishment for baby plant
-
Fruit – houses seeds, does NOT nourish the seed
-
Flower - reproduction
2. List and describe all the characteristics of a monocot and a dicot.
Monocot- One cotyledon, parallel veins, flower parts in multiples of 3, scattered vascular
bundles
Dicot- Two cotyledons, netlike veins, flower parts in 4, 5, Vascular bundles in ring
3. Compare and contrast xylem and phloem in the leaf and the stem?
Xylem carries water up, phloem carries nutrients all over the plant
4. What is photosynthesis? What is the formula? What are the reactants? What are the Products? Where
does it occur in the plant? Where does it occur in the cell?
Photosynthesis is the process where chloroplasts use sunlight to convert light energy into chemical
energy in the form of glucose (sugar).
Carbon dioxide + Water + light  Oxygen + Glucose (sugar)
Photosynthesis occurs in the leaves, more specifically in the chloroplasts of the leaf cells.
5. What is the goal of photosynthesis? To produce glucose in order to then produce energy
6. What are the layers of the leaf?
Epidermis, mesophyll, cuticle
7. What are the parts of the root?
Epidermis, root cap, root hairs, cortex, apical meristem
8. Name and Describe the 4 categories of Plants based on stems.
Shrub, tree, vine, herbaceous plant
9. What is an example of a modified stem?
Potato
10. What are the three major parts of a leaf, draw and label them.
Petiole, blade, veins
11. What is the outside layer of leaves, stems, roots and human skin?
Epidermis
12. What does the waxy cuticle do?
Makes the plant cells waterproof
13. How do the guard cell and stomata work together?
The guard cell opens and closes the stomata
14. What is the function of the stomata?
Gas exchange
15. What is pollination? And what are some different pollinators?
Transfer of pollen to the anther from the stigma. Insects, birds, mammals, weather
16. Name and list the function of each part of the flower.
Flowers are the organs of sexual reproduction in plants. They have the following important structures:
•
Sepals - protect the unopened flower
•
Bud petals - may be brightly colored to attract insects
•
Stamens - Male part of the flower, consisting of the anther and filament, makes pollen grains.
•
Filament anthers - produce male sex cells (pollen grains).
•
Stigma - the top of the female part of the flower which collects pollen
•
Grains ovary - produces the female sex cells (ovules)
•
Pollen - male spores
•
Ovules - female spores
17. What is the difference between self and cross-pollination?
Self- occurs within one flower; Cross- occurs between two flowers
18. What are the three main characteristics of Kingdom Plantae?
Eukaryotic
Multicellular
Autotrophic
