Question

1. sep develop a model using figure 8-16 on the next page as a guide, draw your own models of a prokaryotic cell, a plant cell, and an animal cell. then use each of the vocabulary words from this lesson to label your cells. describe any differences between the models in figure 8-16 and your models. 7. cite evidence what evidence supports the argument that ancestors of mitochondria and chloroplasts once lived as independent organisms?

Explanation:

1. To draw the models, recall the key features of prokaryotic, plant, and animal cells. Prokaryotic cells lack a nucleus and membrane - bound organelles. Plant cells have a cell wall, chloroplasts, and a large central vacuole. Animal cells lack a cell wall and chloroplasts. Compare your models to Figure 8 - 16 based on these features.
2. Evidence for mitochondria and chloroplasts once being independent organisms includes their own DNA (similar to prokaryotic DNA), ability to replicate independently, and having their own ribosomes similar to prokaryotic ribosomes.

Answer:

1. Draw prokaryotic, plant, and animal cell models, label with relevant vocabulary, and describe differences from Figure 8 - 16.
2. Own DNA, independent replication, and prokaryotic - like ribosomes.
