Which refers to swelling as a result of inflammation?
Bad White [126]

Answer: Edema

The swelling that is caused as the result of inflammation is known as Edema. Just after an injury takes place the traumatized area becomes red, painful and warm. It also starts to swell.

This response is trigerred by the injured tissues. When the body starts healing then, change in blood flow takes place and swelling is also cured.

Tomtit [17]

A change in the morphology of the leaves generated can frequently be used to detect when an apical meristem transition from the juvenile to the mature vegetative phase.

<h3><u>Apical meristem: What is it?</u></h3>

The growth zone within the tips of new shoots and leaves as well as the root tips of plants is known as the apical meristem. One of three meristem types, or tissues that can differentiate into distinct cell types, is the apical meristem. Plant growth takes place in the meristem tissue.

Apical growth is defined as taking place at the top and bottom of the plant. While lateral meristems are found between branches, intercalary meristems grow in girth like those of woody plants. The apical meristem is essential for expanding both the roots' and leaves' access to light energy and nutrients. For plants to succeed, they need to grow in both of these directions.
