10 Questions
What is the definition of tissue?
A group of cells that are similar in structure and/or work together to achieve a particular function forms a tissue.
How do unicellular organisms and multicellular organisms differ in terms of cell functions?
In unicellular organisms, a single cell performs all basic functions, while in multicellular organisms, most cells are specialised to carry out specific functions.
Explain the concept of division of labour in multicellular organisms.
Multicellular organisms show division of labour, where cells specialising in one function are grouped together in the body to carry out a particular function efficiently.
Provide examples of functions carried out by 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.
What are the functions of vascular tissues in plants?
Vascular tissues conduct food and water from one part of the plant to other parts.
What is the main difference in tissue structure between plants and animals?
Plants have a large quantity of supportive tissue with dead cells, while animals contain mostly living tissues.
How does the growth pattern of plants differ from that of animals?
Plants have limited growth to certain regions due to the presence of dividing meristematic tissue, while animals have more uniform cell growth without such demarcation.
What are the different types of meristematic tissues in plants?
Meristematic tissues in plants are classified as apical, lateral, and intercalary, depending on their location.
Why do the roots in jar 2 stop growing after they are cut?
The tips stop growing in jar 2 after they are cut because the meristematic tissue, responsible for growth, is located only at certain specific regions.
How does the structural organization of organs and organ systems differ between complex animals and plants?
The structural organisation of organs and organ systems is far more specialised and localised in complex animals than even in very complex plants.
