What is homeostasis in cells?
What is homeostasis in cells? In biology, homeostasis is the state of steady internal, physical, and chemical conditions maintained by living systems. This is the condition of optimal functioning for the organism and includes many variables, such as body temperature and fluid balance, being kept within certain pre-set limits (homeostatic range).

What is light quality?
What is light quality? Light quality is the wavelength (in nanometers, nm) within the electromagnetic spectrum; i.e. blue light is 450 nm and red light is 650 nm. Each wavelength has a different packet of radiation or energy (in J mol-1) called photons. What type of light causes damage to plants? UV-B radiation has been […]
