Mississippi Science FB.3

FB.3 is a cluster heading. These are the individual standards under it.

• FB.3.1

  Compare and contrast prokaryotic/eukaryotic and plant/animal/bacteria cells.

• FB.3.2

  Use models to investigate and explain structures within living cells that support life (e.g., cytoplasm, cell membrane, cell wall, nucleus, mitochondria, chloro...

• FB.3.3

  Compare and contrast active and passive cellular transport. Analyze the movement of water across a cell membrane in hypotonic, isotonic, and hypertonic solution...

• FB.3.4

  Analyze the relationship between photosynthesis and cellular respiration and explain that relationship in terms of the need for all living things to acquire ene...

• FB.3.5

  Use models to explain how ADP and ATP cycle to store and release chemical energy using inorganic phosphate.

• FB.3.6

  Compare and contrast the processes and results of mitosis and meiosis.

• FB.3.7

  Enrichment: Research and orally communicate the possible outcomes of a failure of mitosis (cancer) or meiosis (nondisjunction).

01

What Students Need to Do

Students compare plant, animal, and bacterial cells and use models to explain what their parts do. They predict how materials cross cell membranes and connect photosynthesis, respiration, and ATP. They compare the cells produced by mitosis and meiosis.

02

What Mastery Looks Like

Students place cell parts on models and explain why bacteria have no nucleus. They predict water movement in different solutions and identify which kinds of transport use ATP. They link photosynthesis to respiration, model ATP becoming ADP when phosphate leaves, and distinguish mitosis from meiosis.

03

Common Misconceptions

Students may put nuclei in bacteria or chloroplasts in animal cells. They may think water moves toward lower solute levels or that all transport uses ATP. Some think plants do not respire or that meiosis makes identical cells.

04

How to Assess It

Exit ticket: A plant cell is placed in salt water. Draw an arrow showing water movement, predict what happens to its vacuole, and state whether the movement needs ATP.

1. 01

   Place equal potato strips in fresh water and salt water, then have students measure and explain changes in mass.

2. 02

   Ask students to write how a leaf cell uses chloroplasts and mitochondria to turn sunlight into usable energy.

3. 03

   Give teams cell-part cards and plant, animal, and bacterial cell mats; have them place each card and explain their choices.

4. 04

   Show a healing cut and a trisomy 21 karyotype; ask which involves mitosis and which points to a meiosis error.

• BIO.1A

  Students will demonstrate an understanding of the characteristics of life and biological organization.

• FB.2

  Students will demonstrate an understanding of the structure and interactions of matter and how the organization of matter supports living organisms.

• L.6.1

  Students will demonstrate an understanding that living things range from simple to complex organisms, are organized hierarchically, and function as whole living...

• L.2.3B

  Students will demonstrate an understanding of the interdependence of living things.
