Study Notes
- Tenth grade biology lesson plan duration is 50 minutes.
- Focus is on comparing animal and plant cells.
- NGSS Standard HS-LS1-2 emphasizes hierarchical organization in multicellular organisms.
Learning Objectives
- Students will identify main structures of animal and plant cells.
- Students will compare and contrast plant and animal cells.
- Students will explain plant cell structures' unique functions.
- Students will understand structural differences in plant versus animal cells.
Common Cell Structures
- Cell membrane
- Nucleus
- Cytoplasm
- Mitochondria
- Endoplasmic reticulum
- Golgi apparatus
- Ribosomes
Unique Plant Cell Structures
- Cell wall
- Chloroplasts
- Central vacuole
Comparing Animal and Plant Cells
- Cell Wall: Absent in animal cells, present in plant cells; provides structural support and protection.
- Cell Membrane: Present in both, controls what enters and exits the cell.
- Chloroplasts: Absent in animal cells, present in plant cells; performs photosynthesis.
- Central Vacuole: Small vacuoles in animal cells, large central vacuole in plant cells; stores water and helps maintains turgor pressure.
- Shape: Animal cells are usually irregular, plant cells are usually rectangular, shape is determined by cell wall.
- Nucleus: Present in both, contains genetic material.
- Mitochondria: Present in both, produces energy (ATP).
Activities
- Students work in pairs to discuss why plants need structures that animals don't have.
- Students consider cell structures relation to plant survival needs.
- Plant cell structures in relation to plant characteristics include rigidity and photosynthesis
Homework
- Students create a Venn diagram comparing and contrasting plant and animal cells.
Misconceptions
- All cells are the same shape.
- Animal cells have cell walls.
- All vacuoles are the same size.
