Question

the following diagram represents a cell. which part of the cell can be used to best determine if the cell is eukaryotic and not prokaryotic? a.) part 1 (ribosomes) b.) part 2 (nucleus) c.) part 3 (cytoplasm) d.) part 4 (cell wall) 2.2. the following diagram represents a plant cell. which part of the cell synthesizes sugar through photosynthesis? a.) part 1 (chloroplast) b.) part 2 (endoplasmic reticulum) c.) part 3 (cell wall) d.) part 4 (large central vacuole) list the three parts of the cell theory.

Explanation:

1. Eukaryotic cells have a membrane - bound nucleus, while prokaryotic cells do not. Ribosomes are present in both. Cytoplasm is also found in both types of cells. Cell walls can be present in both prokaryotes and some eukaryotes (like plant cells). So the nucleus is the key feature to distinguish.
2. Chloroplasts are the organelles in plant cells where photosynthesis occurs, synthesizing sugar. The endoplasmic reticulum is involved in protein and lipid synthesis, the cell wall provides structure and protection, and the large central vacuole stores substances and helps maintain cell turgor.
3. The cell theory states that all living organisms are made up of cells, cells are the basic unit of life, and all cells come from pre - existing cells.

Answer:

1. B. Part 2 (nucleus)
2. A. Part 1 (chloroplast)
3. All living organisms are made up of cells; Cells are the basic unit of life; All cells come from pre - existing cells.
