Exam questions on Tissues, organs and organ systems

The human stomach is an organ. Its wall contains muscle tissue that churns the food, glandular tissue that makes digestive juices, and epithelial tissue that covers the inside and outside surfaces.
Explain why the stomach is classed as an organ rather than a tissue.2 marks
A student is making a revision poster about the human circulatory system. It includes the heart, the blood vessels and the blood, which together carry oxygen, nutrients and waste around the body.
Describe the function of the circulatory system and of the respiratory system.2 marks
A student wants to find out how fast water moves up a plant stem. She places identical celery stalks, each with leaves at the top, in beakers of water containing red food dye. She removes one stalk after 1 hour, one after 2 hours and one after 3 hours, and cuts across each stalk to look for the dye.
State a testable hypothesis for the investigation, with a scientific reason, and identify the independent variable.3 marks
