Essential
Questions:
- What are the major components of
the plant body?
- How do genetics and the
environment combine to affect plant growth?
- What are the different plant
tissues and what are their properties?
- How do plants grow and develop?
- What factors affect and control
plant growth and development?
- How does differential gene
expression cause cell differentiation and the different structures of
plant development?

plants?
- What role do leaves, vascular
tissue, and roots play in transport?
- How do the properties of water
play a role in transport?
- How do the processes of
diffusion, osmosis, and pressure affect movement of materials through
plants?
- What are the nutritional
requirements of plants and where do plants get them?
- What role does soil play in
plant nutrition?
- What roles to plants play in
chemical cycles in the ecosystem?
- What is the role of nitrogen on
plant nutrition?
- How do relationships between
plants and other organisms benefit each other and work to cycle
nutrients?
- In what ways are some plants
parasitic?
- How do plants reproduce
sexually?
- How do plants reproduce
asexually?
- How is biotechnology changing
agriculture?

Objectives:
- Identify and describe the major
plant organs.
- Identify and describe plant
tissues.
- Discuss how the environment and
genes work to both impact plant growth and development.
- Explain plant growth and
development.
- Discuss how gene control and
expression control plant growth and development.
- Discuss transport between cell
and across membranes in plants.
- Discuss water potential and how
it affects the movement of water within plants.
- Discuss the movement of water
and mineral into the root and into the vascular cylinder.
- Explain the process of
transpiration powered by water potential.
- Review the properties of water
and explain how this facilitates the movement of water through plants.
- Explain translocation in plants
from source to sink.
- Explain the pressure flow
process.
- Identify the nutritional
requirements of plants.
- Discuss the importance of soil
and how successful agriculture depends on good soil.
- Discuss the importance of
nitrogen to plants and the role plants and the associated bacteria have
in the nitrogen cycle.
- Explore the relationship between
bacteria and plants.
- Explore the relationship between
fungus and plant roots.
- Discuss parasitic and carnivorous
pants.
- Review the reproductive cycles
of mosses, ferns, pines focusing on alternation of generations.
- Discuss the significance of
flowers.
- Identify and give the functions
of the parts of a typical flower.
- Illustrate the sexual
reproduction of flowering plants. From pollen formation, ovule
maturation, pollination, double fertilization, seed development, fruit development.
- Discuss the significance of
pollen from an adaptive standpoint.
- Discuss the significance of
fruit from an adaptive standpoint.
- Explain types of asexual
reproduction on plants.
- Discuss recent advances in
biotechnology that are impacting agriculture.
