Science/7/Focus on Life Science 1.0 All living organisms are composed of cells, from just one to many trillions, whose details usually are visible only through a microscope. As a basis for understanding this concept:
a. Students know cells function similarly in all living organisms.
b. Students know the characteristics that distinguish plant cells from animal cells, including chloroplasts and cell walls.
c. Students know the nucleus is the repository for genetic information in plant and animal cells.
d. Students know that mitochondria liberate energy for the work that cells do and that chloroplasts capture sunlight energy for photosynthesis.
e. Students know cells divide to increase their numbers through a process of mitosis, which results in two daughter cells with identical sets of chromosomes.
f. Students know that as multicellular organisms develop, their cells differentiate.
BRIEF DESCRIPTION
Students will learn about motion and their body at two different levels: cellular and muscular. Students will examine human blood to identify its basic components and will conduct a test to determine their reflex reaction time. Students will also create a flow chart to show the role of cells in muscle contraction.
