NGSS Framework
LS1.B: GROWTH AND DEVELOPMENT OF ORGANISMS
How do organisms grow and develop?
The characteristic structures, functions, and behaviors of organisms change in predictable ways as they progress from birth to old age. For
example, upon reaching adulthood, organisms can reproduce and transfer their genetic information to their offspring. Animals engage in
behaviors that increase their chances for reproduction, and plants may develop specialized structures and/or depend on animal behavior to
accomplish reproduction.
Understanding how a single cell can give rise to a complex, multicellular organism builds on the concepts of cell division and gene
expression. In multi- cellular organisms, cell division is an essential component of growth, development, and repair. Cell division occurs via
a process called mitosis: when a cell divides in two, it passes identical genetic material to two daughter cells. Successive divisions produce
many cells. Although the genetic material in each of the cells is identical, small differences in the immediate environments activate or
inactivate different genes, which can cause the cells to develop slightly differently. This process of differentiation allows the body to form
specialized cells that perform diverse functions, even though they are all descended from a single cell, the fertilized egg. Cell growth and
differentiation are the mechanisms by which a fertilized egg develops into a complex organism. In sexual reproduction, a specialized type of
cell division called meiosis occurs and results in the production of sex cells, such as gametes (sperm and eggs) or spores, which contain
only one member from each chromo- some pair in the parent cell.
Grade Band Endpoints for LS1.B
By the end of grade 2. Plants and animals have predictable characteristics at different stages of development. Plants and animals grow and
change. Adult plants and animals can have young. In many kinds of animals, parents and the offspring themselves engage in behaviors
that help the offspring to survive.
By the end of grade 5. Reproduction is essential to the continued existence of every kind of organism. Plants and animals have unique and
diverse life cycles that include being born (sprouting in plants), growing, developing into adults, reproducing, and eventually dying.
Unpacked Content
2.L.1.1Students know that animals experience a cycle of life which begins with birth, then a period of time in which the
animal develops into an adult. At adulthood, animals reproduce in order to sustain their species. In nature, all animals
are programmed to age and eventually die. The details of the life cycle are different for specific animals.
2.L.1.2
Students know that different animals spend varying periods of time in each stage of the life cycle and that some animals
have few stages, while others have several. Students know that animals might look the same, similar, or completely
different at specific stages of development. Students know that animals may have varied needs at different stages of
development, and may occupy unique habitats according to these needs.
