Plant Parts and Their Functions
1. Compare and contrast the functions of the root to the functions of the stem.
-Root- Absorption and transportation of water and nutrients, anchors the plant and
stores food and water.
-Stem- Transports water from roots to leaves, supports leaves, fruits and flowers,
and food storage
2. Compare a complete flower to an incomplete flower.
-Complete Flower-Has all four parts: male and female
-Incomplete-missing one of the parts either male or female
3. Label the missing parts in both diagrams (parts of the flower and stem)
(See diagram)
4. Define photosynthesis (include formula).
-Process that plants use to produce food.
6CO2 + 6H2O = C6H1206 + 602
5. Define Transpiration.
-Loss of water and exchange of carbon dioxide
6. Compare an imperfect flower to a perfect flower.
-Imperfect flower- lacking either stamens or pistils.
-Perfect flower- has both stamens and pistils
7. Differentiate between a taproot root system and fibrous root system and give an
example of each.
-Taproot- primary root with some small secondary roots
-Examples: Carrots & Turnips
-Fibrous- has small lateral roots that spread out just below soil's surface
-Examples: Grass & Corn
8. Explain the differences between the three types of fruit and give an example of each.
-Aggregate- develop from a single flower, with many ovaries
-Examples: Strawberry & Tulip
-Multiple- Fruit develops from a group of tightly clustered flowers
-Examples: Pineapples & Figs
-Simple- Fruit develops from a single ovary
-Examples: Tomato & Cherry
9. What are the two main functions of the leaf?
-Photosynthesis- food production
-Transpiration- loss of water and exchange of carbon dioxide
10. Name the outer protective covering of the seed?
-Seedcoat
11. What is the purpose of the endosperm?
-Provide nutrition for the developing seed
