Goal 3 Concepts Of Biology

Expectation 3.2 The student will demonstrate an understanding that all organisms are composed of cells which can function independently or as part of multicellular organisms.

Indicator 3.2.1 The student will explain processes and the function of related structures found in unicellular and multicellular organisms.

Assessment Limits:

  • transportation of materials (role of cellular membranes; role of vascular tissues in plants and animals; role of circulatory systems)
  • waste disposal (role of cellular membrane; role of excretory and circulatory systems)
  • movement (cellular – flagella, cilia, pseudopodia; interaction between skeletal and muscular systems)
  • feedback (maintaining cellular and organismal homeostasis - water balance, pH, temperature, role of endocrine system)
  • asexual (binary fission, budding, vegetative, mitosis: role in growth and repair, chromosome number remains the same) and sexual reproduction (angiosperms, mammals)
  • control of structures (cellular organelles and human systems) and related functions (role of nucleus, role of sensory organs and nervous system)
  • capture and release of energy (chloroplasts, mitochondria)
  • protein synthesis (ribosomes)

Brief Constructed Response (BCR) Item - Released in 2006

How do living systems control the movement of materials into and out of cells?

In your response, be sure to

  • identify the cell structures and body systems involved
  • describe the functions of the cell structures and body systems involved
  • identify and describe the processes responsible for the movement of materials into and out of cells

Write your answer in your Answer Book.

The following 8 Anchor Papers represent a range of score points and are used in conjunction with the rubric to assess student responses.

Anchor Paper #1

image of student response

Score for Anchor Paper #1: Rubric Score 1

Annotation: This response demonstrates some understanding of the question. A few body systems which are involved in the movement of materials into and out of cells are named (circulatory system; respritory system), but supporting details are only minimally effective (circulates the materials throuout the body; move materials into and out of the body).


Anchor Paper #2

image of student response

Score for Anchor Paper #2: Rubric Score 1

Annotation: This response demonstrates some understanding of the question. The student identifies a cell structure (vacuoles) and a body system (digestive system) and briefly describes the system function (takes in food). The process of osmosis is identified, but the description is vague (helps to get the body flowing in different ways). Much of the response uses general language (each system plays its part; in different ways; stay healthy; bad or unnecessary materials), resulting in support that is minimally effective.


Anchor Paper #3

Score for Anchor Paper #3: Rubric Score 1

Annotation: This response demonstrates some understanding of the question. The student identifies a cell structure (wall) and minimally describes it's function (semipermeable; allows certain materials in and certain materials out). Body systems are neither identified nor described, and the process responsible for the movement of materials into and out of cells is not mentioned.


Anchor Paper #4

image of student response

Score for Anchor Paper #4: Rubric Score 2

Annotation: This response demonstrates a basic understanding of the question. A cell structure is identified (cell membrane) and its function described (It is a relatively thin membrane that surrounds the cell). Diffusion and osmosis are correctly identified as the processes responsible for the movement of materials into and out of cells (Certain substances, like water, can pass through the cell membrane unassisted in a process called diffusion; also called osmosis). The use of accurate scientific terminology (active transportation; carrier proteins) helps support the response. Overall, supporting details are adequate.


Anchor Paper #5

Score for Anchor Paper #5: Rubric Score 2

Annotation: This response demonstrates a basic understanding of the question. The student identifies and describes several body systems involved in getting nutrients to and from the body's cells (digestive system breaks down your food; carries the nutrients through the bloodstream; waste products are diffused out of the cells). The use of accurate scientific terminology (filtered out by nephrons) is present in the response. The process responsible for the movement of materials into and out of cells is identified and briefly described (The nutrients then enter your cells through diffusion). Overall, the supporting details are adequate.


Anchor Paper #6

image of student response

Score for Anchor Paper #6: Rubric Score 3

Annotation: This response shows a good understanding of the question. The description of the cell membrane is generally complete (surronded by a membrane that is selectively permeable; only allows certain objects and matter leave and enter the cell; this membrane is composed of fatty acids and proteins; two layers; part of the fatty acid is hydrophilic) and concludes this discussion with some synthesis of information (The purpose of having a selectively permeable membrane is to allow the cell control what will enter and leave). The processes responsible for the movement of materials into and out of cells are identified and described (The movement of water across the membrane is called osmosis; Diffusion is the movement of a substance from an area of high concentrate to an area of low concentrate). Accurate scientific terminology strengthens the response (hydrophilic; hydrophobic; ATP). A discussion of body systems and more supporting detail are needed for a higher score.


Anchor Paper #7

image of student response

Score for Anchor Paper #7: Rubric Score 3

Annotation: This response demonstrates a good understanding of the question. Cell structures and the circulatory system are identified and described (the cell membrane, the cell pores [way for material to get in and out] the vacuoles [transportation of materials]; the blood vessels [taking material/blood cells and circulating around the body] arteries, veins, the heart [for taking in/out oxygen necessary to go in and out of cell to perform cell functions]). The process responsible for the movement of materials into and out of cells is identified and described (In diffusion, the material being transported goes from a higher concentration to a lower concentration). Accurate scientific terminology (active transport; vacuoles) strengthens the response. The supporting details in the response are generally complete.


Anchor Paper #8

image of student response

Score for Anchor Paper #8: Rubric Score 4

Annotation: This response demonstrates a full and complete understanding of the question. Cell structures and body systems involved in the control of movement of materials into and out of cells are identified and described with pertinent and complete supporting details (cell membrane and membrane protiens actually take things in and excrete them out; Body systems such as the digestive and circulatory systems are responsible for bringing nutrients to cells and taking waste away; When we eat food, the digestive system [stomach, intestines] break it down and it is absorbed into the blood [circulatory system]). The processes responsible for the movement of materials into and out of cells are integrated into the discussion of cell structures and body systems (Different methods transport these nutrients into and out of the cell: diffusion is when lipid-soluble things travel across the membrane to a place with a lower concentration of that thing, because of the osmotic pressure produced by the difference in concentration). Accurate scientific terminology (lipid-soluble; osmotic pressure; protien channels; co-transport protiens; ATP; concentration gradient; endocytosis; exocytosis) enhances the response.
