Support and Movement

What this topic covers

Determine the need for support and movement in organisms. Identify plant supporting tissues (collenchyma, sclerenchyma, xylem, phloem fibres) and describe their distribution in root, stem, leaf. Relate plant responses to stimuli (light, water, gravity, touch) and the roles of auxins in tropism. Relate the location of chitin, cartilage, and bone to their supporting function in animals. Relate the structure and general layout of the mammalian skeleton to its supportive, locomotive, and respiratory functions. Differentiate types of joints with examples. Apply protective, supportive, locomotive, and respiratory functions of the skeleton to animal well-being.
