We want to connect the people who have knowledge to the people who need it, to bring together people with different perspectives so they can understand each other better, and to empower everyone to share their knowledge.
Reflect 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.

See lessYou may have noticed that fibres of coconut husk are hard and brittle, whereas the leaf stalks of coriander are soft and flexible. Find out the reason.
Coconut husk fibres are hard and brittle because they mainly contain sclerenchyma tissue with thick lignified cell walls that provide strength and rigidity. In contrast, coriander leaf stalks contain collenchyma tissue with pectin-rich uneven walls. This tissue gives flexibility and support, allowinRead more
Coconut husk fibres are hard and brittle because they mainly contain sclerenchyma tissue with thick lignified cell walls that provide strength and rigidity. In contrast, coriander leaf stalks contain collenchyma tissue with pectin-rich uneven walls. This tissue gives flexibility and support, allowing the stalks to bend easily without breaking during movement or external pressure.
