Unit 1-Lesson 7

Question 1

List the characteristics of a Plant?

Answer 1

• Eukaryote and multicellular
• Autotrophic
• Reproduce sexually; can also produce asexually
• Cellulose in cells walls; similar to algae
• The photosynthetic colouring for land plants is chlorophyll

Question 2

What are some supportive and anchoring structures for plants?

Answer 2

Stems and roots

Question 3

What is the Vascular (nutrient transport) system?

Answer 3

System of conductive tissue that transports water (xylem) and sugars (phloem)

Question 4

List the characteristics of Bryophytes

Answer 4

• Non-vascular plants (depend on diffusion/osmosis)
• Include mosses, liverworts, hornworts
• No roots, flowers or seed present
• Grow in low, tangled mats in moist, shaded areas

Question 5

List the characteristics of Pteridophytes

Answer 5

• Seedless, vascular plants
• Include whisk ferns, club mosses, horsetail, ferns
• No flowers or seeds present
• Grow taller than bryophytes in moist, tropical areas

Question 6

List the characteristics Spermatophytes

Answer 6

• Seed-producing, vascular pants
• Roots, stems, and leaves present in different varieties
• Reproduces by means of a protective seed which contains the plant embryo

Question 7

List the characteristics of a Gymnosperms

Answer 7

• Produce “naked” seed exposed on the surface of cone scales
  
  • Ex. pines, spruces, cedar (conifers)
• Thin, needle like leaves with waxy cuticles for hot/dry summers, cold winters and moderate rainfall

Question 8

List the characteristics of Angiosperms

Answer 8

• Flowering pants
• Produces seeds enclosed by fruit
  
  • Ex. roses, trilliums, birch, maple oak tree, grass, wheat, weeds, etc.
  • Since the fruits are enclosed by a fruit, animals can eat the fruit then secrete as waste so that the plant can grow
