Study Notes
Objectives
- Familiarize with technical botanical terms for efficient plant description and identification.
- Understand key plant parts, particularly flower anatomy.
Plant Terminology
- Used for plant identification through dichotomous keys, featuring paired questions for classification.
Basic Plant Anatomy
- Life Span: Duration from germination to death (annual, biennial, perennial).
- Life Habit: General form of the plant (herbaceous, woody, moss, tree).
- Leaf Complexity: Distinguishes between simple (one leaf) and compound (multiple leaflets).
- Leaf Arrangement: Refers to the positioning of leaves on the stem (known as phyllotaxy).
- Leaf Morphology: Describes the shape of leaves or leaflets.
- Leaf Margin: Describes the edge of the leaf.
- Leaf Venation: Refers to the arrangement and pattern of veins in leaves.
Applied Example
-
Queen's Cup (Clintonia uniflora):
- Life Span: Perennial, utilizing rhizomes.
- Life Habit: Herbaceous, non-woody structure.
- Leaf Complexity: Simple leaves present.
- Leaf Arrangement: Basal arrangement.
- Leaf Morphology: Oblong or elliptic shape.
- Leaf Margin: Entire edge, smooth in texture.
- Leaf Venation: Parallel vein pattern.
Flower Anatomy
- Perfect Flowers: Contain both male (stamens) and female (carpels) reproductive parts.
- Imperfect Flowers: Lack either male or female parts, classified as unisexual.
- Dioecious Plants: Have male and female flowers on separate plants ("2 Houses").
- Monoecious Plants: Have both male and female flowers on the same plant ("1 House").
Life Span Categories
- Annuals: Complete lifecycle in one season.
- Biennials: Take two seasons to complete lifecycle.
- Perennials: Live and reproduce for more than two seasons.
Leaf Arrangement (Phyllotaxy)
- Refers to how leaves or leaflets are organized along the stem, influencing light capture and photosynthesis efficiency.
Leaf Morphology (Shape)
- Familiarize with various leaf shapes; focus on three identifiable types seen in local flora.
