Coconut husk fibres are used for mats which are tough and fibrous. Which tissue has structural features suitable for providing this strength? Explain why living parenchyma couldn’t serve the same purpose.
Coconut husk fibres contain sclerenchyma tissue, which has thick, lignified and dead cells that provide great strength, hardness and durability. These characteristics make the fibres suitable for tough mats and ropes. Parenchyma tissue could not serve this purpose because its living cells have thinRead more
Coconut husk fibres contain sclerenchyma tissue, which has thick, lignified and dead cells that provide great strength, hardness and durability. These characteristics make the fibres suitable for tough mats and ropes. Parenchyma tissue could not serve this purpose because its living cells have thin walls, soft texture and mainly perform storage and photosynthesis instead of providing rigid mechanical support.

See lessTissues in Action. Explain.
“Tissues in Action” describes how cells divide, specialise and organise themselves into tissues organs and organ systems. Similar cells work together to perform specific functions like movement, protection, transport and coordination. In plants and animals, tissues create division of labour, makingRead more
“Tissues in Action” describes how cells divide, specialise and organise themselves into tissues organs and organ systems. Similar cells work together to perform specific functions like movement, protection, transport and coordination. In plants and animals, tissues create division of labour, making body functions more efficient. The chapter explains growth, tissue structure, functions and coordination in living organisms for survival and development.

See lessHow is the study of cells and tissues significant for understanding the life processes and human welfare?
Studying cells and tissues helps scientists understand important life processes like growth, reproduction, movement, healing and transport of substances. This knowledge supports medical treatments organ repair, tissue culture, genetic engineering and disease control. It also improves agriculture thrRead more
Studying cells and tissues helps scientists understand important life processes like growth, reproduction, movement, healing and transport of substances. This knowledge supports medical treatments organ repair, tissue culture, genetic engineering and disease control. It also improves agriculture through better crops and plant regeneration methods. Therefore, understanding cells and tissues is essential for scientific progress, healthcare development and human welfare.

See lessHow are tissues in plants and animals different and why?
Plant and animal tissues differ in structure and function because plants and animals have different lifestyles. Plants are fixed and need supporting, conducting and growing tissues. Animals move actively and require muscular, nervous and flexible tissues for movement and coordination. Plants prepareRead more
Plant and animal tissues differ in structure and function because plants and animals have different lifestyles. Plants are fixed and need supporting, conducting and growing tissues. Animals move actively and require muscular, nervous and flexible tissues for movement and coordination. Plants prepare food through photosynthesis, while animals digest food. Therefore, their tissues develop differently according to their functional needs.

See lessHow is the division of labour at various levels of organisation in multicellular organisms correlated with their structure and function?
Multicellular organisms show division of labour through organised levels like cells, tissues organs and organ systems. Each structure is specialised for a particular function. For example, muscles help movement while nerves control coordination. Their structures suit their functions perfectly. ThisRead more
Multicellular organisms show division of labour through organised levels like cells, tissues organs and organ systems. Each structure is specialised for a particular function. For example, muscles help movement while nerves control coordination. Their structures suit their functions perfectly. This organisation increases efficiency, improves coordination among body parts and helps organisms perform complicated activities necessary for growth, survival and reproduction.
