Just posterior to the olfactory lobes is the cerebrum (B), and it is the frog's thinking center. The cerebrum helps the frog respond to its environment. Posterior to the cerebrum are the optic lobes (C), which function in vision.The ridge just behind the optic lobes is the cerebellum (D), it is used to coordinate the frog s muscles and maintain balance.he cerebrum helps the frog respond to its environment.

Mitochondria are unusual organelles. They act as the power plants of the cell, are surrounded by two membranes, and have their own genome. They also divide independently of the cell in which they reside, meaning mitochondrial replication is not coupled to cell division.
Plants lack specialized immune cells âall plant cells participate in the plant immune response. Chloroplasts, along with the nucleus, cell membrane, and endoplasmic reticulum, are key players in pathogen defense. Due to its role in a plant cell's immune response, pathogens frequently target the chloroplast.
