What is the primary function of nerve cells in human beings?
What is the primary function of nerve cells in human beings?
Why are specialized cells in multi-cellular organisms considered efficient?
Why are specialized cells in multi-cellular organisms considered efficient?
Unicellular organisms, a single cell performs all basic ______s. For example, in Amoeba, a single cell carries out movement, intake of food and respiratory gases, respiration and excretion. But in multi-cellular organisms there are millions of cells. Most of these cells are specialised to carry out a few ______s. Each specialised ______ is taken up by a different group of cells. Since these cells carry out only a particular ______, they do it very efficiently. In human beings, muscle cells contract and relax to cause movement, nerve cells carry messages, blood flows to transport oxygen, food, hormones and waste material and so on. In plants, vascular tissues conduct food and water from one part of the plant to other parts. So, multi-cellular organisms show division of labour. Cells specialising in one ______ are often grouped together in the body. This means that a particular f.

Study Notes
Cellular Organization
- In unicellular organisms, a single cell performs all basic functions such as movement, intake of food and respiratory gases, respiration, and excretion.
Specialization in Multi-Cellular Organisms
- In multi-cellular organisms, millions of cells are specialized to carry out a few functions.
- Each specialized function is taken up by a different group of cells.
- Since these cells carry out only a particular function, they do it very efficiently.
Functions of Specialized Cells in Human Beings
- Muscle cells contract and relax to cause movement.
- Nerve cells carry messages.
- Blood flows to transport oxygen, food, hormones, and waste material.
Functions of Specialized Tissues in Plants
- Vascular tissues conduct food and water from one part of the plant to other parts.
Division of Labour in Multi-Cellular Organisms
- Cells specializing in one function are often grouped together in the body.
- This means that a particular function is carried out very efficiently.
