What Are the Basic Parts of a "Tomato" Plant?

Your "tomato" plant is your baby.

You need to care for it accordingly, give it attention, and be good to it.

And of course, to do all of those things, you need to know your "tomato" plant. You need to understand its structure, how each part of its delicate little body works, what makes it happy, and what makes it tick.

Before you can grow luscious plants, you need to know your plant. 

Like machinery, each part of a plant has a specific purpose, and together, they form a greater purpose—to give you that mind-tingling feeling you look for in your sticky icky. 

Without further ado, here's what your plant looks like:

Cannabis basic parts


Imagine the leaves as the solar panels of your panels of your plant. They power your sweet, sweet babies by taking light from your light source for photosynthesis.

We've covered photosynthesis before, but here's a quick refresher: it’s the process in which plants take light energy, usually from the sun, and turns that into chemical energy.

Chemical energy is what’s stored in the bonds of chemical compounds, like atoms and molecules. It’s the potential energy of a chemical, called such because it’s got the potential to make energy during a chemical reaction. When a chemical reaction happens, heat is usually one of the byproducts.

So, the energy that a chemical reaction creates is its chemical energy. Chemical energy is what your plants need to create other certain chemicals that attribute to the freshest "tomatoes."


The nodes of your plant are the intersections between your plant stems and leaves. Manipulating nodes can help you determine the way your plant grows.

Depending on what your grow space looks like, you can prune some of the new leaf growth so that your plants' stems can concentrate on growing upwards. Plants that are tall and spindly aren't actually ideal for "tomatoes," as chances are, the stems won't be able to support the weight of your growth.

Even worse, if they grow too tall, then you run the risk of burning your leaves, and as we learned above, your leaves are paramount!

Similarly, if you want your plants to grow bushier—which is something we recommend—you can promote lateral growth. When you manipulate your plants' nodes, you're training the plant.

One form of training is called topping. "Topping" your plant involves cutting the top of your plant between the nodes. Through doing this, you'll get a better plant shape and possibly even bigger yields.

Do be careful when you top your plants, though—you don't want to accidentally pinch off top growth as opposed to topping the plants between their nodes. 

As well, be sure do this only during the vegetative stage of growth. Don't ever cut your plant when it's making buds!


If your plant's stem is a highway, your branches are your plant's many streets. Through these branches, nutrients can be carried from the root system, via the stem, into each leaf.


Life is a hiiiiiiighway.... and so is the stem. 

It's one of the main structural components of your plant, and from the stem, nodes will develop. The stem carries all the nutrients from the roots to all edges of the plant.

Without your stem, well, there'd be no plant at all. If you ever accidentally snap this, it's game over. Treat 'em with respect.

Root ball

The root ball is the intense concentration of all your roots, where the stem transform into roots. 

When you repot your plants, this is where your root balls come into play. The quality of it will directly affect how well your plants will actually survive getting placed into its new environment.


As if you didn't already suspect how important roots were. 

They're the stuff that will help your plant suss out all the nutrients that your plants need to grow big and strong. They will reach far and wide for your plants.

Your roots are your lifelines. 

A word of caution, though: if you have too many nutrients, you could damage your plant because your roots will suck that right up. 

With proper care of your plants, guarded with this knowledge, you'll be growing the most amazing yields you've ever had... in a BCNL box, of course.

It's time to start growing, fam!
