How to grow your own Cannabis, Part 4: Cannabis Anatomy

All living things are made up of different parts, that have different functions. This is known as biological anatomy. What organs and 'parts' are we made of, and what is their purpose?

Most plants are similiar, and Cannabis itself, is a plant. 

The most basic parts of a cannabis plant, are the

  • Roots
  • Stems
  • Leaves
  • Reproductive Organs

Of course, each of these can be broken down into further and further sub categories and items.

These specific and their functions include:

Above-Ground Structures

  1. Cola – The cluster of buds that grow tightly together at the top of the plant. It is the most potent part, rich in cannabinoids.
  2. Bud (Flower) – The reproductive part of the female plant containing high concentrations of cannabinoids (THC, CBD, etc.). Used for consumption.
  3. Trichomes – Tiny, crystal-like glands covering the buds and leaves, producing cannabinoids and terpenes. They give cannabis its potency and aroma.
  4. Pistils (Stigmas) – Hair-like structures that emerge from the calyx. They collect pollen from male plants for reproduction. Their color changes indicate maturity.
  5. Calyx – A protective layer of small leaves that enclose the reproductive organs. It forms the base of the flower and contains trichomes.
  6. Sugar Leaves – Small leaves coated with trichomes surrounding the buds. Often used for extracts and concentrates.
  7. Fan Leaves – Large, broad leaves essential for photosynthesis. They do not contain high cannabinoid levels but are vital for plant health.
  8. Branches – Support structures for buds and leaves, allowing nutrient and water transport.
  9. Stem (Main Stalk) – Provides structural support and transports water and nutrients from the roots to the leaves and buds.

Below-Ground Structures

  1. Roots – Absorb water and nutrients from the soil, anchoring the plant. They help in overall plant health and stability.

Each part plays a critical role in the growth, potency, and reproduction of the cannabis plant.

Of course, different strains have different genetic expressions of the above 'organs'. We use these genetics to grow out stains to suit our needs. Some growers might grow a strain that can be extracted well (larger trichome heads) or some growers might prefer a strain with less trichomes, but more CBD. The wide variety anatomy of a plant is what makes Cannabis so interested and attractive to cultivators of all shapes and sizes.
