A leaf normally consists of the following parts: the epidermis, the mesophyll, and the veins.
The epidermis cover the upper and lower surfaces (the outside) of the leaf. It contains many types of cell tissues that protect against water loss, regulates the exchange of gases, secretes metabolic compounds and in some leaves controls the absorption of water.
The mesophyll, or middle leaf, is where photosynthesis usually occurs. It is often made up of two layers, the palisade and the spongy layers.
The veins consist of the Xylem and the Phloem tubes. The Xylem tubes carry water and minerals from the roots to the leaf and the Phloem tubes move sap out of the leaf.
Bluegills have internal fertilization, where the male releases sperm inside the female's body to fertilize her eggs.
The fluid link between the external and internal environment is the plasma membrane of cells. It acts as a selectively permeable barrier that regulates the passage of substances in and out of the cell, maintaining the cell's internal environment while interacting with the external environment.
The tongue is an internal organ located in the mouth. It is a muscle that helps with various functions such as chewing, swallowing, and speaking.
Butterflies reproduce by internal fertilization and not by external fertilization. Butterflies, like most insects, will then lay the eggs and wait for them to hatch.
