The document outlines a two-week science unit on plant and animal cells and body systems. Week one focuses on plant cell structure and function, including transport within plant vascular systems. Key concepts covered include the roles of xylem, phloem and cambium in moving water, nutrients and food. Week two shifts to human body systems, with lessons on circulatory, respiratory and digestive systems. Students learn system components and functions through readings, videos, labs and activities. The unit provides an overview of key life science topics.
