Cannabis Plant Anatomy

A pretty complex structure makes parts of a marijuana plant look truly fabulous. By studying cannabis anatomy, you can get useful theoretical knowledge that will help you both when growing or when choosing goods on the shelf of the dispensary.

Have you ever wondered how complicated the structure of hemp flowers is? Their appearance is filled with mystery, but with some knowledge, you can explain any puzzle. Therefore, in this article, we will mainly talk about female marijuana plant anatomy and the structure of their buds.

Male and Female Hemp Plants

Cannabis plants are of two sexes: male and female, but there are also bipedal hermaphrodites of hemp. The structure of plants of both sexes is significantly different. It is important to know that our favorite buds are formed on female cannabis plants. Buds of undiluted female plants that do not have seeds are especially valuable.

Pollen Sacs

Reproductive pollen bags, the opening of which is pollination of female flowers are formed on male plants. After that, seeds begin to form in the female buds. Hermaphrodite plants have both female and male sexual characteristics, which is the cause of self-pollination and seed formation. Such mutations are extremely undesirable because of a significant deterioration in the quality of the harvest and the loss of pure female marijuana anatomy genetics.

Any grower can be guaranteed to receive female plants. For this purpose, it is necessary to use feminized marijuana seeds, acquired in a safe place, or obtained by pollination. Another reliable way is the cloning of a mother plant.

Marijuana Cola

Branches with growing buds on them are called colas. Each plant has a main cola located at the top of the central stem. It is the largest and densest cluster of buds. Other side branches, growing from internodes, form secondary colas. Usually, these colas reach much smaller sizes, but their mass can be increased using different methods of plant training, such as LST (Low-Stress-Training) and green screen (ScrOG). Sometimes colas ripen at different times. In many cases, the main stakes come before the others due to uneven lighting.


The anatomical flowers of female hemp plants are called buds. Outwardly, they resemble small droplets-like outgrowths. Looking at any marijuana bud more carefully, you can see these little cups abundantly covered with trichomes among small “sugar” leaves. They contain a large number of different cannabinoids and other useful substances.


Probably everyone has ever thought about the purpose of small orange hairs, abundantly covering buds. They are called pistils and have a reproductive function: after pollination, they begin the process of seed emergence. The pistils grow out of cups, and initially, they have a straight shape and white color. As the pistils mature, they begin to bend and turn yellow. Over time, they become darker and more orange and brown, and gradually dry out.


It is equally important to know about the trichomes’ anatomy of a marijuana plant. They are small glandular hairs that secrete terpenes, THC, and other cannabinoids. If you take a closer look at the buds, you will notice a white crystalline scale on their surface. In the process of maturation, you can observe the changes that occur with them: at the initial stage of development, they are tiny and transparent, but over time trichomes stretch and become more turbid, and even later – amber. The effect of cannabis will largely depend on the degree of maturation of the trichomes.

Experts in cannabis farming are constantly working to improve the genetics of different varieties, studying different cells, tissues, and parts of a weed plant, as well as the compounds contained in them. Knowledge about the anatomy of cannabis plant helps to understand its vital processes better, especially the most important one – the formation and maturation of buds.
