ANALYZE & EXPLAIN 1. Why do you think the Elodea leaf cells have chloroplasts, but the onion cells do not?

2. ANALYZE & EXPLAIN
1. Why do you think the Elodea leaf cells have chloroplasts, but the onion cells do not? What does this tell you about how structure is related to function in different plant tissues?
2. What structure gives the animal cell (cheek cell) its outer boundary? How is this different from the plant cell's outer boundary?
3. All three cells have some of the same structures. What does this suggest about what cells need in order to survive?
4. Plant and animal cells do not look exactly the same and do not contain exactly the same structures. How can two different types of cells still carry out the processes necessary for life? Use evidence from today's investigation and what you learned from The Organelles.

Answer

  1. The Elodea leaf cells have chloroplasts for photosynthesis, which is necessary for their function in capturing sunlight. Onion cells, which are part of the root, do not perform photosynthesis and therefore do not need chloroplasts. This shows that cell structure is related to the specific function of the cell in the plant.

  2. The animal cell's outer boundary is the cell membrane, which is different from the plant cell's outer boundary that includes a cell wall. The cell wall provides additional support and structure to plant cells.

  3. All cells have a nucleus, cytoplasm, and mitochondria, suggesting that these structures are essential for basic cellular functions such as energy production, genetic information storage, and overall cell maintenance.

  4. Despite differences in appearance and structure, both plant and animal cells have organelles that perform essential functions such as energy production, protein synthesis, and waste processing. These shared functions allow both types of cells to sustain life.
