7th Grade Science Lesson Plans: Unit- The Cell
Ms. Wendy Bramlett
Title: Characteristics and functions of the Cell
Objectives:
2.) Identify functions of organelles found in eukaryotic cells, including the nucleus, cell
membrane, cell wall, mitochondria, chloroplasts, and vacuoles.
Example: mitochondria releasing energy for use in cellular respiration
• Identifying components of the cell theory
• Identifying cells as prokaryotic or eukaryotic
• Listing the sequence of the mitotic cell cycle
5.) Identify major differences between plants and animals, including internal structures, external
structures, methods of locomotion, methods of reproduction, and stages of development.
Procedure:
 Students will identify characteristics of Prokaryotic and Eukaryotic cells.
 Students will list the three components of the cell theory and how they were developed.
 Students will work in groups to research the structure and function of the organelles in a plant
and an animal cell. They will compile this information into a chart by describing the orgnanelle,
stating its function, what type of cell the organelle can be found it and creating an analogy
where the organelle is compared to a part in a city.
 Working in groups, students will draw, label and color the 13 major organelles, on index cards.
Groups will use these cards to create a large Double Bubble Map. The two outer circles will be
labeled “Plant Cell” and “Animal Cell” and the inner circle will be labeled “both”. Students will
place their index cards under the appropriate category on the map.
 Students will have a choice of 7 different tasks they may complete. Each task is worth a stated
amount of points. Student selections must add up to a total of 50 points but they may complete
additional tasks for extra credit. Tasks include:
1. Graphic Organizer of cell parts and functions 10 points
2. Questions on cells 20 points
3. Cell mathematics 15 points
4. Science fiction story 20 points
5. Identify cell structure 10 points
6. Mini Lab “Modeling Cytoplasm” 15 points
7. Mini Lab “Observing Magnified Objects” 15 points
 Students will use all the information they have learned to create a cell city. Students will work
in groups and will brainstorm about the type of city they will draw. They will identify what part
of the city each organelle is represented by and then draw a picture of their city. They will
create a legend that explains what part of the city represents each organelle. They will finish by
writing an analogy that explains why they chose each part of their city to represent a certain
organelle and what function they both share.
 Students will do AMSTI Lesson 7 Exploring Cells Lab where they draw and measure an algal cell,
an onion leaf cell and elodea leaf cell and explore an animal cell.
