Morphological Structure of Plant Roots in Biology
The root is the main part of the plant which is located beside the stems and leaves that can grow towards the core of the earth cormus. This root has many functions and roles in supporting plant metabolism.
Nature of Roots in Plants
Is a part of plants that are usually found in the soil, with the direction to grow to the center of the earth "Geotrope" or to the water "Hydrotrope", and leave the air and light.
It has no books, is also not continuous and does not support leaves or scales or other parts.
In the color is not green, but usually whitish or yellowish.
Growth continues at the edges, but generally growth is still less rapid when compared with the surface of the soil.
And the shape of the tip is often tapered, until it is easier to be able to penetrate the ground.
Root Function in Plants
To support and strengthen the establishment of plants in their places of life.
To absorb water and mineral salts "nutrients" from the soil.
Transporting water and food substances that have been absorbed to places on the body of plants that need a saint.
In some types of plants that function as a means of respiration such as mangroves.
In some types of plants, some are useful as a place to store food reserves or as a means of vegetative reproduction. For example carrots that have enlarged taproots, which function as a place to store food. Meanwhile, the breadfruit plants from the roots can grow shoots that will be able to grow into new individuals.
Morphological Structure of Plant Roots
neck / root base "Collum"
Which is the part that connects the roots with the stems of plants.
"Corpus Radicis" Root Bar
Which covers the part between the root neck and root tip.
"Radix Lateralis" Root Branch
Which is part that is not directly connected to the base of the root, but out of the main root and can form branching roots again.
Root hair / root feather "Pilus Radicalis"
Branched fine hairs that grow from epidermal cells that grow near the tip of the root, which serves to expand the area of absorption of water and mineral nutrients. It can be said that root hair. Root hair is the part that grows due to protrusion of long root bark cells that are shaped like hair or hair.
"Apex radicis" Root Tip
Which is the lowest part of the morphology of the roots of plants that are protected by the "kaliptra" root cap. This section is the youngest part of the root consisting of tissues that are still actively experiencing growth.
"Kaliptra" Root Headscarf
Which is the very tip of the root that serves to protect the root against damage when penetrating soil particles. The special part contained in this root cap is the caliptra which is composed of parenchyma cells which sometimes contain starch.
Kaliptra functions as a protective meristem and lubricates the roots so that the friction between the root and the soil is reduced when the roots penetrate the soil pores. Generally in many plants, kaliptra forms a special structure called columella.
