LIVING ORGANISMS AND HUMAN BODY
You should know how each of these single-celled organisms moves, eats,
reproduces and secretes waste. You should be able to compare and contrast any
two of them.
Volvox
Paramecium
Euglena
Amoeba
A cell is the smallest part of any living thing. You should be able to recognize,
describe and explain the functions of each of the following cell parts.
Found in plant and animal cells
Cell membrane
Cytoplasm
Nucleus
Nuclear membrane
Mitochondria
Golgi bodies
ribosomes
Endoplasmic reticulum
Vacuoles (central vacuole in plant cells)

The human body (and other animals) is organized into cells, tissues, organs and
organ systems. You should be able to explain the relationship between these and
compare them to the organization of something else (school, city, building, car,
etc.)
The human body is organized into organ systems. They all work together to
benefit the entire body. You should know the function of each system listed. You
should be able to explain how they work together and provide specific examples.
Urinary
Circulatory
Muscular
Skeletal
Digestive
Nervous
Endocrine
Immune
Reproductive
Respiratory
Asexual Reproduction (one parent)
 offspring is identical to parent
 mitosis
 fragmentation
 budding
 binary fission
Sexual Reproduction (two parents)
 offspring is different from parents; gets ½ its chromosomes from each
parent
 sex cells made by meiosis
 sex cells = gametes = egg and sperm in humans
 requires fertilization of egg by sperm
You should be able to compare and contrast the stages and purpose of mitosis
and meiosis.
interphase, prophase, metaphase, anaphase, telophase, cytokinesis
You should be able to use a Punnett square to determine the genotype of the
offspring when given the genotype or other information about the parents.
