Cell Biology

1. 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.
