Prepare for the Ag Associate Plant Science Unit Exam with a focused study resource covering essential plant science concepts, plant propagation methods, soil fertility, fertilizer analysis, plant nutrients, and photosynthesis. This exam review explores sexual and asexual plant propagation, seed production, stem cuttings, leaf cuttings, root cuttings, plant grafting, and tissue culture propagation. It also reviews annual and perennial plants, monocotyledons and dicotyledons, the primary plant nutrients nitrogen, phosphorus, and potassium (NPK), and secondary nutrients calcium, magnesium, and sulfur. Strengthen your understanding of nitrogen, phosphorus, and potassium deficiency symptoms, fertilizer analysis percentages, complete fertilizers, and fertilizer-label interpretation, including the meaning of a 10-10-8 fertilizer analysis. Additional topics include photosynthesis, the role of sunlight, water and carbon dioxide in sugar production, and the Calvin cycle’s light-independent reactions involving ATP and NADPH. Designed for agricultural students, Ag Associate learners, plant science students, and agriculture exam candidates, this resource helps organize key definitions and concepts into a convenient revision guide. Use it to reinforce your understanding of plant growth, reproduction, nutrition, and energy processes while preparing for classroom tests and agricultural science assessments. Updated for the 2026/2027 study period and available for convenient digital access.

, plant propagation
Practice of growing plants from seeds or from vegetative parts
asexual plant propagation
a process by which identical offspring are produced by a single parent; methods include
the cuttings of leaves and stems, and plant tissue culture, etc
Sexual plant propagation
involves seeds, produced by two individuals, male and female in practically all instance.
Most plant propagation is, in fact, from seed, including all annual and biennial plants.
Annual plants
Live only one season and must be replanted each yea, which causes enormous disruption
to soil (Example: wheat and corn)
Perennial plants
Live for multiple years so there is no need to plow fields each year for replanting
