Division of labor in a multicellular organism refers to the specialized functions carried out by different cell types or tissues to support the overall functioning of the organism. Each cell type has specific roles and responsibilities that contribute to the organism's survival and growth. This division of labor allows for efficient functioning and coordination among cells in the organism.
Most animal species have evolved interdependently with their conspecifics. Different characteristics of each species' environment dictated how inderdependent the individuals became, through evolutionary history. (see Dawkins' The Selfish Gene) The highest level of interdependence occurs in insects, within the order Hymenoptera (ants and bees) as well as termites (order Blattoidea). In these species, division of labor occurs such that the colony functions as a genetic individual, in the sense that they all share the same genes and if the colony does not survive to reproduce, each individual's fitness is zero. Because they are connected so strongly, division of labor has evolved such that members are each born into a specific role to help the colony survive to reproduce. Non-breeding workers procure food and provide defense against predators, while the queen and outside males are the only ones who actually mate. All members' roles are essential for the colony to succeed.
Cells have specialized functions. Muscle cells have the ability to contract or to relax. Bone cells have great rigidity and tensile strength. Red blood cells have the capacity to transport oxygen. Nerve cells are designed to perform data processing. Liver cells have various chemical synthesis capabilities. Etc.
is the sharing of different functions among its cells, tissues, organs and systems.
Division of labour ensures the smooth functioning of a multicellular organism and its survival.
The division of labor among cells of multicellular organisms is the sharing of different functions. Division of labor ensures that the multicellular organism functions smooth and survives.
division of labour means that in a multicellular organism work is divided in many cells but in a unicellular organism all the work is done by a single organism

What is meant by the term embryo?
An embryo is the early stage of development of a multicellular organism, following fertilization of an egg cell by a sperm cell. It is characterized by rapid cell division and differentiation that ultimately gives rise to the tissues and organs of the organism.
What is meant by the term multicellular?
Multicellular refers to organisms that are made up of more than one cell. These cells are specialized to perform different functions within the organism, allowing for more complexity and larger size compared to single-celled organisms. Organisms such as plants, animals, and fungi are examples of multicellular organisms.
How are the cells of multicultural organism different from unicellular organisms?
Multicellular organisms are made up of specialized cells that work together to carry out various functions, while unicellular organisms are single-celled entities that perform all functions by themselves. Multicellular organisms have cell differentiation and division of labor, whereas unicellular organisms are capable of independent existence. Multicellular organisms have a higher level of cellular organization and complexity compared to unicellular organisms.
What is significance of division of labor in an organism?
Division of labour means that different tissues and organs of the body take different functions in a multicellular body. For eg. in human body lungs have taken the function of purifying blood, heart has taken the function of pumping the blood, intestines have taken the function of absorbing food and water...
What is meant by cell specialization?
Cell specialization refers to the process where cells develop specific functions and characteristics to perform specific tasks within an organism. This allows for division of labor among cells and contributes to the overall complexity and efficiency of multicellular organisms. Each specialized cell type has a unique structure and set of functions that enable the organism to carry out essential processes.

What is meant by an alternation-of-generations life cycle?
An alternation-of-generations life cycle is a reproductive strategy where an organism alternates between a multicellular diploid stage (sporophyte) and a multicellular haploid stage (gametophyte) in its life cycle. This cycle enables the organism to undergo both sexual and asexual reproduction at different stages.
What is meant by social division of labor explain with the help of examples how social division of labor creates conditions for exchange?
Social division of labor is an aspect of division of labor. It shows the social structure of the technical division of tasks, between firms and workers, or between countries or towns, and focuses on exchange markets. A prime example is one where one town is better equipped for creating food, but another is better suited for creating clothes. As these two towns specialize through social division of labor, they find it beneficial to exchange.

The new regional division of labor created by improved transportation meant that?
The South specialized in cotton, the West in grain and livestock, and the East in manufacturing.
Define what is meant by a limiting factor Give examples?
A limiting factor limits the development or growth of a population, an organism or process. Examples include: shortage of skilled labor and materials, limited labor hours and machine hours.
What is meant by division of labor in biology?
different parts of a body do different things. your heart pumps blood, your lugs absorb oxygen and expel carbon-dioxide, etc.
What is meant by a 'system' in an organism?
It means that an organism is full of cells.
What is meant by a 'system' in a organism?
It means that an organism is full of cells.
Do all living organisms begin life as a single cell?
Yes, all living organisms begin life as a single cell, which is formed through the fusion of an egg and a sperm during fertilization. This single cell then undergoes cell division to grow and develop into a multicellular organism.
What is meant by the word parasite?
An organism that grows, feeds, and is sheltered on or in a different organism while contributing nothing to that organism in payment.
