Definition: A tiny organism that floats in water and is part of plankton, which includes various small plants and animals.

Example: The plankter is an essential part of the aquatic food chain, providing nourishment for larger marine animals.

Definition: Relating to organisms that drift in water, especially in oceans or lakes, and are unable to swim against currents.

Example: The planktic organisms play a crucial role in the aquatic food web.

Definition: A group of tiny organisms that live in water, including plants and animals, which float or drift and are an important food source for larger creatures like fish.

Example: Plankton are essential to the ocean's food chain, providing nourishment for many marine animals.

Definition: Describing organisms that float in the water, especially in the open sea, rather than living on the bottom of the ocean.

Example: The planktonic creatures are essential for the marine food web.

Definition: A small, free-swimming larva that is typically flat and has tiny hair-like structures called cilia, found in certain marine animals like jellyfish and corals.

Example: The planula eventually settles on the ocean floor to develop into a polyp.

Definition: A flat, often decorative plate or disk that can be engraved or used for information, or a buildup of substances like bacteria on a surface, especially on teeth.

Example: The dentist removed the plaque from my teeth during the check-up.

Definition: A substance that is a part of living cells, often referring to the fluid or material in which cells are suspended or the genetic material involved in heredity.

Example: The scientist studied the germ plasm to understand how traits are inherited.

Definition: A clear, yellowish fluid found in blood, lymph, or other bodily fluids that carries cells and nutrients. It can also refer to a state of matter made up of charged particles, such as ions and electrons.

Example: The doctor explained that the plasma in blood helps transport nutrients and waste.

Definition: A jelly-like substance found in the cytoplasm of certain cells, especially in amoebas, that helps in movement and shape changes.

Example: The amoeba extended its pseudopod, filled with plasmagel, to capture food.

Definition: A hereditary structure that can replicate itself and is believed to exist in the cytoplasm, functioning similarly to chromosomal genes but independently from them.

Example: Scientists are studying plasmagenes to understand how they influence traits in organisms.
