Unicellular means that the organism is made up of one cell. This one cell can get and produce everything the organism needs to live. What are five characteristics of protists? 1. Most are unicellular. 2. Eukaryotic cells: have a nucleus. 3. A very diverse group of organisms. 4. ...
A complete multicellular definition can be understood by breaking the word down into its component parts. The prefix "multi" means many and cellular means about or involving cells. So, a multicellular organism definition is: an organism that is made of many cells, such as plants, animals or ...
Cells may be typified in different ways. For instance, based on the presence of a well-defined nucleus, a cell may be eukaryotic or prokaryotic. Cells may also be classified based on the number of cells that make up an organism, i.e. ”unicellular”, ”multicellular”, or ”acellular”....
What are the stages of cell differentiation? cell differentiation, process by which an immaturecelldevelops into a specialized cell type with a distinct structure and function. Cell differentiation is a crucial part ofdevelopmentin multicellular organisms, since it results in cells with unique characteri...
The present view is that differential activity ofgenesis the basis for cellular andtissuedifferentiation; that is, although the cells of a multicellular body contain the same genetic information, different genes are active in different cells. The result is the formation of various gene products, whic...
Eukaryote refers to any of the single-celled or multicellular organisms whose cell contains a distinct, membrane-bound nucleus. Organisms such as animals, plants, fungi, and protists are examples of eukaryotes because their cells are organized into compartmentalized structures called organelles, such as...
Eukaryotic cells are cells which contains a nucleus enclosed within the nuclear membrane. Protozoa, fungi, plants, and animals are the few eukaryotic organisms.
Unlike protists, however, rotifers are metazoans which means that they are multicellular organisms whose cells have differentiated into tissues and organs. Though members of the group exhibit significant morphological variations allowing them to adapt to their respective habitats, they share several ...
Structures and types of simple epithelia. Surface epithelium 1/2 Synonyms: Epithelium Epithelium is one of only 4 types of human body tissues. Like all types, it is formed by cells within an extracellular matrix (ECM). The cells in this tissue are tightly packed within a thin ECM. For...
There are two types of reproductive organs found in a gametophyte: Archegonium: A multicellular sex organ in the female that creates eggs. It is like an ovary in females because both structures form haploid cells of the egg. Antheridium: A Multicellular sex organ in the male that produces sp...
