First half of BIOLOGY UNIT OBJECTIVES
I Can
Students will understand and the characteristics that all living
things share.
Students will recognize and appropriately use terms relating to
biology – these terms are listed under the vocab link under “Bio
Unit Resources”
Students will understand the 7 level system of classification and be
able to order them from broadest to most specific; they will
recognize the components of an organism’s scientific name
Students will be understood the process of photosynthesis and the
process of cellular respiration and they will understand how the
balance of these two processes keeps levels of oxygen and carbon
dioxide in our atmosphere at acceptable levels.
Students will understand the basic structure of a plant and an
animla cell including the function of each of the following
organelles: nucleus, cell membrane, ribosomes, mitochondria,
cytoplasm, cell wall, chloroplasts
Students will be label the organelles listed above in a diagram of the
Students will be able to successfully use the microscope, calculate
the overall magnification, and identify the following specimens:
amoeba, paramecium, hydra, red blood cells, animal cells, plant
cells and red blood cells
Students will understand the relationship between structure and
function and be able to explain this relationship in regard to a red
blood cell.
Students will understand the processes of osmosis and diffusion and
will make accurate predictions about the direction in which
molecules will move across the membrane if given sufficient
information.
Students will recognize that the cell membrane is semi-permeable
and that this is one mechanism which helps the cell maintain
homeostasis.

Students will understand how each of the four major blood types (A,
B, AB, and O) differs from each other, and identify the possible
genotype for each blood type.
Students will correctly predict the success or failure of a given
transfusion, using their knowledge that the body can recognize
familiar proteins and accept them, while destroying unfamiliar
proteins.
Students will be able to prepare a slide of their own cheek cells and
recognize major features of the cell under the microscope (nucleus,
cytoplasm, and cell membrane)
Students will understand compare and contrast bacteria and
viruses, understanding that both can enter your cells and disrupt
homeostasis.
Students will understand how a feedback loop works and will be
able to appropriately classify examples of positive vs. negative
feedback; recognizing that both mechanisms are aimed at
maintaining homeostasis
Students will compare and contrast the processes of mitosis and
meiosis and name cells formed through each process
Students will recognize asexual vs. sexual reproduction and list the
pros and cons of each
Students will recognize karyotypes and extract information from
them about the individual whose chromosomes are pictured.
Students will utilize Punnet squares to successfully predict the
potential genotypes and phenotypes of the offspring of a given
couple.
Students will understand the following patterns of inheritance:
dominant, recessive and co-dominant.
