In biology, support and movement are essential functions that allow organisms to maintain their structure and perform activities such as walking. Skeletal systems, including bones and cartilage which facilitate movement through muscle contractions, are often used in animals to provide support. In plants, support is achieved through various structures like cell walls, For multiple-choice questions and further exploration of support and movement in biology, visit Nokryan.com.
