Biology Honors
Objectives

Discuss basic classification and characteristics of plants. Identify bryophytes,
pteridophytes, gymnosperms, and angiosperms.

Know characteristics (adaptations) as well as factors that affect survival of plants
on land.

Relate the structure of each of the major plant organs and tissues to physiological
processes.

Discuss the primary function of roots, stems and leaves.

Describe the function of plant tissues (Dermal, vascular xylem and phloem,
ground)

Identify the parts of the flower and differentiate between pollination, double
fertilization, dispersal and germination. Understand the sequence


Shoot System
Root System
Roots: Anchor, absorbs water and minerals, stores nutrients.
Types: Taproot, Fibrous roots
Root hairs increase SA of absorption
Stems: Transport, support, growth.
Key terms: Nodes, internodes, apical bud, axillary bud
(Meristems: Primary and secondary growth)
Types: Woody stems and herbaceous stems
Leaves: Photosynthesis
Mesophyll: Middle leaf cross section
Types: Simple, compound, double compound.
*All structures can be modified depending on species
