Definition: In a way that relates to the endosteum, which is the tissue lining the inner surface of bones.

Example: The cells were observed endosteally, indicating their location within the bone.

Definition: A thin layer of cells that lines the inner surface of bones, specifically the medullary cavity.

Example: The endosteum plays a crucial role in bone growth and repair.

Definition: A structure found in some marine animals, consisting of folds in the inner layer that help trap food particles in the throat area.

Example: The endostyle in tunicates plays a crucial role in feeding by secreting mucus to capture food.

Definition: A harmful chemical used to kill insects and mites on crops, known for its high toxicity.

Example: Farmers used endosulfan to protect their crops from pests, but it is very dangerous to health.

Definition: A living thing that exists inside the body or cells of another living thing.

Example: The endosymbiont provides nutrients to its host in exchange for protection.

Definition: A situation where one organism lives inside the body or cells of another organism, forming a close relationship that benefits both.

Example: The theory of endosymbiosis explains how certain organelles in cells, like mitochondria, originated from free-living bacteria.

Definition: Relating to a type of symbiosis where one organism lives inside the cells or body of another organism.

Example: The endosymbiotic theory explains how certain organelles in eukaryotic cells originated from free-living bacteria.

Definition: The inner layer of tissue found in certain plant structures, such as the anther of a flower or the capsule of a moss.

Example: The endothecium plays a crucial role in the development of pollen grains within the anther.

Definition: Relating to the thin layer of cells that line the blood vessels and organs in the body.

Example: The endothelial cells play a crucial role in maintaining vascular health.

Definition: A type of tumor that originates from the cells lining blood vessels or lymphatic vessels.

Example: The doctor diagnosed her with endothelioma after reviewing the biopsy results.
