The process by which plants lose water in the form of liquid from hydathodes is:
A. Transpiration
B. Evaporation
C. Guttation
D. Bleeding
Answer: Option C
Solution (By JKSSB Mock Tests)
Guttation is the exudation of water droplets containing dissolved minerals from hydathodes at leaf margins, driven by root pressure when transpiration is low. Transpiration is vapor loss, bleeding is sap from cut tissue.
Explanation:
Fungi are eukaryotic, mostly multicellular (except yeast), and are heterotrophic by absorption (saprophytic or parasitic). Their cell walls contain chitin. Monera are prokaryotic, Protista are unicellular eukaryotes, Plantae are autotrophic multicellular organisms. Fungi play key roles as decomposers in ecosystems.
Explanation:
A stroke (cerebrovascular accident) occurs when blood supply to part of the brain is interrupted, causing tissue death. Myocardial infarction is heart attack, aneurysm is vessel ballooning, embolism is blockage by a traveling clot.
Explanation:
Lymphatic vessels collect interstitial fluid (lymph) and return it to the venous circulation (subclavian veins). This maintains fluid balance. Along the way, lymph nodes filter pathogens. The heart pumps blood, kidneys filter blood, lungs exchange gases. The lymphatic system is unidirectional.
