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?
I assume you meant to write multicellular, not multicultural. The cells in multicellular organisms have a nucleolus, a nuclear envelope, mitochondria, lysosomes, an Endoplasmic Reticulum, and a Golgi Apparatus. Unicellular organisms have none of these. Plant cells also have a central vacuole, plasmodesmata, and plastids. Both have a nucleus, ribosomes, a cytoplasm, and a cell membrane. Both bacteria (unicellular) and plants and fungi (multicellular) have cell walls, but they are different.
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?
Cellular SpecializationThe cell performing a specific function for a larger organ or tissue."cell specialization is an adaptation to do a particular job in a cell"

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 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.
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.
Do all living organisms begin life as a single cell?
Well, that depends how strictly you want to define your terms. This is because some organisms reproduce by cell division, but not grow (as in physical, individual, singular growth). But if instead of grow you mean proliferate (meaning to become more of whether it be growth or reproduction) then we must define cell division. Since some organisms proliferate by cell budding (not strictly cell division) they would not fall under this category. Therefore if you meant do all living organisms proliferate by multiplying cells, then yes, in laymans terms. However if you meant strictly any of the above, then no.
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.
