of cells have different structures. Look at these two images of cells. Do you observe any differences between the plant and animal cells?
1. Why do you think that plants and animals have different types of cells? Cite specific examples to support your answer. (Short as possible)
This model of an animal cell shows many parts of the cell that you cannot see with a typical light microscope. Look at the structure of each cell part. Describe the cell parts that you see. What do you think would be the function of each of these cell parts in an animal cell?

Answer

  1. Plant cells have a rigid cell wall, chloroplasts, and usually one large central vacuole. Animal cells lack cell walls and chloroplasts and usually have a rounder or more irregular shape.

  2. Plants and animals have different needs. Plant cells have chloroplasts to make food using sunlight and rigid cell walls for support; animal cells lack these structures and are more flexible.

  3. The visible portion of the model shows these cell parts:

    1. Cell membrane: The thin outer boundary controls what enters and leaves the cell.
    2. Cytoplasm: The yellow material surrounding the organelles supports them and is where many chemical reactions occur.
    3. Nucleus: The large purple structure contains DNA and directs cell activities.
    4. Nucleolus: The darker region inside the nucleus makes ribosomal components.
    5. Nuclear envelope: The boundary around the nucleus has pores that regulate movement into and out of the nucleus.
    6. Endoplasmic reticulum: Folded membranes near the nucleus make and transport proteins and lipids; rough ER has ribosomes attached.
    7. Ribosomes: Tiny dots make proteins.
    8. Mitochondrion: The orange, bean-shaped structure with inner folds produces ATP, the cell’s usable energy.
    9. Small vesicles: Small rounded sacs store or transport substances; some may contain enzymes for digestion.
  4. Yes—the displayed answer correctly explains the main differences between plant and animal cells.
