Plant Identification/ Classification
Plant Identification/ Classification
Plants can be classified/ identified in many ways and the use of the plant will determine the system used. The following are some of the ways in which plants can be either identified or classified:
Plant Taxonomy
Plant Taxonomy
The system of classifying plants into a hierarchy consisting of the following units:
Kingdom: one of the three great divisions of nature (in this case vegetation/vegetable)
Phylum: The highest grouping in the taxonomy of plant or animal kingdoms.
Class: Things (plants ) grouped according to common characteristics or qualities.
Order: a category in between class and family in botanical classification.
Family: subdivision in the classification of plants usually consisting of several genera.
Genus: group of species of plants believed to have descended from a common ancestor.
Species: related to the naming of plants and animals.
Consider:
Consider:
What is the taxonomic classification of plants?
What are the eight (8) groups included in a taxonomic classification?
How are plants based into each group?
Based on Its Life Cycle
Based on Its Life Cycle
Annual: Plants that grow and complete their life cycle within one year.
Biennial: Plants that require two growing cycles or two years to complete their life cycle.
Perennial: Plants that grow year to year and produce seeds each year.
Consider:
Consider:
What is a life cycle?
What are the differences between annual, biennial and perenniel plants?
Give one common example of a vegetable that falls into each category?
Growth Habit
Growth Habit
Creepers: Plants which grow horizontally along the ground.
Climbers: Plants which grow vertically using walls, other plants, etc. for support.
Herbs: Plants grown for their flavour, aroma, or medicinal value and whose stems above ground do not become woody.
Shrubs: Woody perennial plants smaller than trees, They usually have permanents stems branching from or near the ground.
Trees: perennial plants with permanent, woody, self-supporting main stem or trunk; usually grow to considerable height with branches developing some distance from the ground.

Consider:
What characteristic is used to classify plants in this type of classification?
What is the difference between each type of group in this category of classification?
Part of Plants Used for Food
Part of Plants Used for Food
Roots and tubers e.g. Irish potato, cassava, coco, dasheen.
Grains and pulses, e.g. corn, legumes.
Fruits, eg. mango, citrus, pineapple.
