Terminal bud

Look how big he is getting! Here shown is the internode. It is placed between two nodes and will spawn a new leaf. It may also be the terminal bud which signifies the last stem to grow on the leaf.

Roots

My baby bean roots.

Beutiful Mono's (corn) roots

There are four types of roots in a plant

• Adeventituous root- Adventituous roots are roots that grow in abnormal locations such as from a stem.
• Tap root- A tap root is a vertical downword root that has outgrowths of other roots on it
• Primary root- Are the first root produced by a germinating seed
• Lateral root- Spawn from the primary root to anchor the plant

Roots have little hairs at the end called root hairs. These function as ways for the plant to bring in nutrients and water to promote growth.

Mono

As said in Di's post, the leaves provide storage, food, and means of respiration for the plant. Along with the leaves, Mono has a tough protective layer called the dermal tissue. Along with the cuticle, this helps retain water and protect from surroundings.

The node is where a branch originates and the internode is a node between two nodes. 

Bean growth

So Di is doing great. Look at that broad leaf that is developing!  Leaves allow a plant to get food via photosynthesis, go through respiration, and store food.

Growth

Alright its that time to teach of growth my young padawons.

• First off is the meristem. This is the part of the plant that is constantly dividing to form new tissue so the plant thus keeps growing.
• The primary structure is growth of the buds to form leaves while secondary structure is the further growth of roots and stems.
• The vascular cambium is the early stages of the vascular system in a plant.
• Hormones involved in plants growth include auxin, cytokinin, ABA, and gibberlin. For now I'm going to take auxin and cytokinin for an example. Auxin is a harmone that coordinates growth and behavioral processes in a plant's development. Cytokinin is a hormone that promotes cell division and differentiation thus the growth of the plant.
• A trophism is when there is a stimulus in the environment and a biological organism reacts to that. Here in my case there is limited sunlight where I have my plants during certain parts of the day. During the morning the sunporch outside blocks the sun and when it passes over around 4pm it get less and less sun as the window begins to block light as the sun moves west. Here is a great illustration of trophism as my baby corn is now leaning towards the source of sunlight.

Corn

I don't mean to exclude my other child, Mono. I love them equally. His growth has been great, if not better than that that of Di (bean).

Further showing the rapid growth of the stem. These three pictures were over a timespan of two days
