Reflect on any of the physical practices you are Fig. 3.24 familiar with, such as yoga, kabaddi, etc. How would it support bone and muscle health?
Yoga, kabaddi and other physical activities support bone and muscle health by strengthening muscles, improving flexibility and increasing endurance. These activities improve blood circulation, posture, balance and coordination. Regular exercise also increases bone density, reduces stiffness and prevRead more
Yoga, kabaddi and other physical activities support bone and muscle health by strengthening muscles, improving flexibility and increasing endurance. These activities improve blood circulation, posture, balance and coordination. Regular exercise also increases bone density, reduces stiffness and prevents obesity. Such practices keep joints flexible and lower the risk of fractures, muscle injuries and lifestyle-related health problems.

See lessReflect on any gardening methods you know, such as pruning, grafting, irrigation or crop rotation. How does each practice support the healthy functioning of plant tissues like meristems, conducting tissues or supporting tissues?
Pruning removes unwanted branches and stimulates apical and intercalary meristem growth, producing healthy shoots. Grafting joins conducting tissues like xylem and phloem for proper transport of water and nutrients. Irrigation supplies water essential for tissue functioning and growth. Crop rotationRead more
Pruning removes unwanted branches and stimulates apical and intercalary meristem growth, producing healthy shoots. Grafting joins conducting tissues like xylem and phloem for proper transport of water and nutrients. Irrigation supplies water essential for tissue functioning and growth. Crop rotation improves soil fertility, reduces disease and supports healthy development of meristematic, conducting and supporting tissues in plants.

See lessWhat might be the reason for the presence of different types of cells and tissues?
Different cells and tissues exist because living organisms perform various complex activities. Through differentiation, cells develop specialised structures suited for specific functions such as transport, support, protection, movement and coordination. This specialisation creates division of labourRead more
Different cells and tissues exist because living organisms perform various complex activities. Through differentiation, cells develop specialised structures suited for specific functions such as transport, support, protection, movement and coordination. This specialisation creates division of labour among tissues and organs. As a result, body functions become more organised, efficient and coordinated in multicellular plants and animals.

See lessWhat protects plants from mechanical injury, water loss, harmful microorganisms and extreme environmental conditions?
Plants are protected by the epidermis, the outermost protective tissue covering all plant parts. Its tightly packed cells and waxy cuticle prevent excessive water loss and protect against mechanical damage, microorganisms and environmental stress. Root hairs increase absorption of water and mineralsRead more
Plants are protected by the epidermis, the outermost protective tissue covering all plant parts. Its tightly packed cells and waxy cuticle prevent excessive water loss and protect against mechanical damage, microorganisms and environmental stress. Root hairs increase absorption of water and minerals, while stomata help in gaseous exchange and transpiration, supporting proper functioning and survival of plants.

See lessWhat keeps a plant upright? Why does a fresh twig bend but a dry twig break? Why are seed coats hard and how do aquatic plants float?
Plants remain upright due to supporting tissues like parenchyma, collenchyma and sclerenchyma. Fresh twigs bend because flexible collenchyma supports them, while dry twigs break because they lose flexibility. Sclerenchyma makes seed coats hard and strong due to lignin deposition. In aquatic plants,Read more
Plants remain upright due to supporting tissues like parenchyma, collenchyma and sclerenchyma. Fresh twigs bend because flexible collenchyma supports them, while dry twigs break because they lose flexibility. Sclerenchyma makes seed coats hard and strong due to lignin deposition. In aquatic plants, specialised parenchyma contains air spaces that reduce weight and help plants float on water.
