AI-generated practice question — model-generated for extra practice, not a previous-year CBSE board question.
Lymph is a fluid derived from blood plasma that leaks out through the pores of capillary walls into the surrounding tissues. It is a colourless fluid containing white blood cells (lymphocytes). It is formed when plasma, proteins, and blood cells are forced out of the blood capillaries into intercellular spaces, and is then collected by lymph capillaries.
This question is from Chapter 6 (Life Processes) — specifically the section on transportation in animals. The source passages provided are from Chapter 7 (Reproduction) and do not contain information about lymph, so this answer is based on the standard CBSE Class 10 NCERT textbook content for that topic. Key examiner expectations: define lymph, mention it is derived from plasma, state it contains WBCs/lymphocytes, and briefly describe its formation from capillary filtration into intercellular spaces. Do not confuse lymph with blood.
