What are the differences and similarities between human body tissues and plant tissues?

All living organisms are made up of cells. A group of cells that work together performing a function are called tissues. For both plants and animals, tissues are a group of cells working together. These tissues vary in their structure, function, and origin.


Animals have four tissue types: epithelial, connective, muscle, and nervous. Epithelial tissue covers the surface of all internal and external organs. Muscle tissue forms the three types of muscles: skeletal, cardiac, and smooth. They help in movement by contracting and relaxing. Connective tissue connects the different tissues, organs, and parts of the body. Examples include fat, blood, bone, and cartilage. Nervous tissue is made up of nerve cells. They conduct and transmit electrical impulses.


Plant tissue is divided into two groups: meristematic tissue and permanent tissue. Meristematic tissue includes cells with the capability to divide. This allows the cells to enlarge and then increase the length and width of the stem, roots, and leaves. Permanent tissue is a derivative of meristematic tissue. It aids in the function of the conduction of substances and storage of food. From these groups three tissue types are formed: ground, dermal, and vascular. Vascular tissue includes xylem and phloem. The dermal tissue includes the epidermis.

Is there a word/phrase for "unperformant"?

As a software engineer, I need to sometimes describe a piece of code as something that lacks performance or was not written with performance in mind. Example: This kind of coding style leads to unmaintainable and unperformant code. Based on my Google searches, this isn't a real word. What is the correct way to describe this? EDIT My usage of "performance" here is in regard to speed and efficiency. For example, the better the performance of code the faster the application runs. My question and example target the negative definition, which is in reference to preventing inefficient coding practices. Answer This kind of coding style leads to unmaintainable and unperformant code. In my opinion, reads more easily as: This coding style leads to unmaintainable and poorly performing code. The key to well-written documentation and reports lies in ease of understanding. Adding poorly understood words such as performant decreases that ease. In addressing the use of such a poorly ...

Is 'efficate' a word in English?

I routinely hear the word "efficate" being used. For example, "The most powerful way to efficate a change in the system is to participate." I do not find entries for this word in common English dictionaries, but I do not have an unabridged dictionary. I have checked the OED (I'm not sure if it is considered unabridged), and it has no entry for "efficate". It does have an entry for "efficiate", which is used in the same way. Wordnik has an entry for "efficate" with over 1800 hits, thus providing some evidence for the frequency of use. I personally like the word and find the meaning very clear and obvious when others use it. If it's not currently an "officially documented" word, perhaps its continued use will result in it being better documented.
