Classification
1.What are the four plant classifications?
a. Bryophytes, Pteridophytes (ferns), Gymnosperms, and Angiosperms
1.What does phloem carry?
a.Carries food
1.What is the function of leaves in all plants?
a.Make food—photosynthesis
1.What is a cotyledon?
Seed leaf
1.What is the reproductive organ for an angiosperm?
a.Flower
2. Which was the first classification to have seeds?
a. Gymnosperms
2.What does xylem carry?
a.Water & minerals
2.What is the chemical found in plants responsible for collecting sunlight?
a. Chlorophyll
2.What are three seed dispersal methods?
a.wind b.water c.animals
2.What are the three parts of the carpel (female flower reproduction organ)?
a. Stigma, style, and ovary
3. Which three classifications of plants HAVE vascular tissue?
a. Pteridophytes b. Gymnosperms c. Angiosperms
3.What is the scientific name of a stem that is green and flexible?
a.Herbaceous
3.Where in the leaves does photosynthesis take place?
a. Chloroplasts
3.What does Mesophyll mean?
a.Middle leaf
3. What are the two parts of the stamen (male reproductive organ)?
a. Anther and filament
4.Explain WHY Bryophytes aren't tall.
Lack of vascular tissue prevents them from transporting water/minerals up a tall plant, so they must absorb water/minerals through osmosis.
4.What is the other type of stem besides herbaceous?
a.Woody
Photosynthesis is the primary purpose of leaves. What is the CHEMICAL formula for photosynthesis? Must use correct numbers!
a.6CO2 + 6H2O → C6H12O6 + 6O2
4.Following the steps of a seed plant’s life cycle, what happens after seed formation, but before germination (plant development and growth)?
a.Seed dispersal
4.What tissue do angiosperms contain that bryophytes do not contain?
a. Vascular tissue
5.Which classification of plants is the most diverse?
Angiosperms
5.What are the two functions of stems?
a.Structural support b.Transportation of food and water
What are the openings in the leaves that allow for gas exchange?
Stomata
5.What is a swollen plant ovary that protects the seed during dispersal?
a. Fruit
5. What is one characteristic that can distinguish monocots from dicots?
a. Number of cotyledons, leaf vein patterns, floral part sets (3's or 4's/5's), number of pollen grain pores, vascular tissue bundling.
