Step 1
Describe the function of a meristem in the growth of a plant.
Answer
Meristem cells are undifferentiated, meaning they have the ability to divide and produce more cells. They do this by mitosis, allowing for growth and development of the plant. The cells produced can then differentiate into specialized types that contribute to various plant structures.
Step 2
Describe how the student would prepare a microscope slide using these cells.
Answer
To prepare a microscope slide, the student should:
- Use a thin section of the cells from the meristem.
- Add a stain or small amount of water to the cells to enhance visibility.
- Place a cover slip gently on top of the sample to avoid air bubbles.
Step 4
Step 5
Describe how a prokaryotic cell is different from the cell in Figure 3.
Answer
Prokaryotic cells differ from eukaryotic cells in several ways:
- They do not have a nucleus; their genetic material is free-floating in the cytoplasm.
- Prokaryotic cells lack membrane-bound organelles, such as mitochondria.
- They usually have circular or plasmid DNA instead of linear chromosomes.
