Eukaryotic cells

Eukaryotic cells are complex in organization and structure, especially when you consider their small size. Consider the organelle contents of the typical eukaryotic cell. Select two organelles and compare them relative to structure and function. Describe what would be the specific probable effects on the cell if each of these organelles were lost. Try to avoid picking the same pair as other students in your class.

Chloroplasts are the organelles that convert light energy to the chemical energy of food. Another distinction is that plant cells have a protective cell wall outside the plasma membrane. We'll see other differences and similarities between plant and animal cells as we now take a closer look at the architecture of eukaryotic cells, beginning with the plasma membrane.

Mitochondria and Chloroplast, both have originated from endosymboitic bacteria, and have double outer membrane, they have their own DNA, and they reproduce independently and have ribosomes capable of synthesizing proteins.

They do have differences mitochondria is present in all eukaryotes size is 0.5 to 10 micrometers breaks glucose to release energy and carries out respiration. Chloroplast present in plants, algae size is 2 to 10 micrometers builds up glucose to store energy and carries out photosynthesis.

If mitochondria are removed from the cell, it cannot carries out respiration and food present in cell cannot be used to release energy. The cell will die. If chloroplast is absent from the plant cell, there will be no food synthesis by photosynthesis. No food, no energy and eventually the cell will die
