The student will investigate and understand that all living things are composed of cells. Key concepts include
cell structure and organelles
similarities and differences between plant and animal cells
development of cell theory
cell division
Cell Structure
The structure of a cell organelle is suited to the function carried out by
that organelle.
Division of labor within a cell is essential to the overall successful function of the cell.
Similarities and differences in plants and animals are evident at the
cellular level.
Plant and animal cells contain some of the same organelles and some that differ.
distinguish among the following: cell membrane, cytoplasm, nucleus, cell wall, vacuole, mitochondrion, endoplasmic reticulum, and chloroplast.
Using images from a light microscope, identify plant and animal cells.
Cell Theory
Cell theory includes the following components:
all living things are
composed of cells;
cells are the smallest unit (structure) of living things
that can perform the processes (functions) necessary for life;
living
cells come only from other living cells.
know the three components of the cell theory
The development of cell theory can be attributed to the major
discoveries of many notable scientists.
The development of cell theory
has been dependent upon improvements in the microscope technologies
and microscopic techniques throughout the last four centuries.
Continuing advances in microscopes and instrumentation have increased
the understanding of cell organelles and their functions. Many of these
organelles can now be observed with a microscope (light, electron).
Cell Cycle
Cells go through a life cycle known as the cell cycle.
The phases of the
cell cycle are interphase, mitosis, and cytokinesis.
know the steps in the cell cycle, including the phases of mitosis
The purpose of mitosis is to produce new cells for growth and repair
that are identical to the parent cell.
The purpose of meiosis is to produce reproductive (sex) cells that carry half the genetic material of the parent.
Know the purpose of and difference between mitosis and of meiosis.
