Leucocytopoiesis
Leucocytopoiesis is the process by which stem cells in the bone marrow differentiate into different types of white blood cells, also known as leukocytes. This process involves the production of various cell types, including neutrophils, lymphocytes, monocytes, and eosinophils, each with specific functions in the immune system. Leucocytopoiesis is a vital process that helps the body fight infections and maintain overall health.
Leucocytosis
Leucocytosis is a medical term that refers to an abnormal increase in the number of white blood cells in the blood, typically as a response to infection, inflammation, or trauma. In a normal person, the white blood cell count remains relatively stable. However, during leucocytosis, the number of white blood cells increases, which can be a sign of an underlying infection, disease, or inflammatory process.
Leucocytozoon
Leucocytozoon refers to a genus of parasitic protozoa that infects the white blood cells of birds, causing a disease called leucocytozoonosis. The parasites are transmitted to birds through the bite of an infected tick or other arthropod. In infected birds, the parasites multiply inside the white blood cells, causing damage and eventually leading to anemia, jaundice, and death if left untreated.
Leucodendron
Leucodendron is a genus of flowering plants in the family Proteaceae, native to southern Africa. They are often referred to as "silver trees" due to the silvery-gray color of their leaves. The name "Leucodendron" comes from the Greek words "leucos" meaning white, and "dendron" meaning tree, likely referring to the pale color of the leaves.
Leucoderma
Leucoderma is a medical term that refers to a skin condition characterized by white patches or discoloration, usually caused by a lack of melanin production or damage to melanocytes, the cells responsible for skin pigmentation. It is also known as vitiligo.
Leucoedema
Leucoedema is a rare condition where the skin becomes white and weak, typically due to a deficiency of mucopolysaccharides in the skin. This condition is also characterized by the loss of skin elasticity and moisture, leading to the appearance of aged skin.
Leucoerythroblastic
Leucoerythroblastic refers to a type of blood cell that is intermediate in development between a white blood cell (leukocyte) and a red blood cell (erythrocyte). It is a developmental stage in the differentiation of blood cells from stem cells in the bone marrow. Leucoerythroblastic cells are often seen in conditions such as bleeding disorders, bone marrow disorders, and certain types of cancer, where there is an increase in the production of immature blood cells.
Leucoethiopic
Leucoethiopic refers to the pale Ethiopian skin color. It is a term used to describe the light-colored skin tone of some people of Ethiopian or Eritrean descent. The word is derived from the Greek words "leukos", meaning white or pale, and "Aethiopia", referring to Ethiopia. However, it's worth noting that this term is somewhat outdated and not recommended for use, as it has been criticized for perpetuating a harmful and racist stereotype. It's generally considered more appropriate to use terms that respect the diversity and individuality of people of all skin tones.
Leucoethiops
Leucoethiops is a rare and obsolete word that refers to a type of white or pale-colored moth in the genus Leucoethiops. The word is composed of the Greek words "leukos," meaning white, and "ethiops," meaning Ethiopian, likely due to the moth's pale color resembling that of the people of Ethiopia. Today, this word is mainly of interest to lepidopterists, or insect enthusiasts, and is no longer commonly used in everyday language.
Leucogenes
Leucogenes is a rare or obsolete word that refers to a white or light-colored fungus, usually growing on decaying organic matter. The term is derived from the Greek words "leukos", meaning white, and "genos", meaning producing or giving birth to.

Leucoline refers to a type of coloring substance or dye that is typically used in the coloring of papers, textiles, and other materials. The term "leucoline" comes from the Greek words "leukos," meaning "white," and "line," meaning "line" or "thread." In essence, leucoline is a white dye that is often used to create contrasting colors or to enhance the visibility of certain details on a surface.
Leucoma
Leucoma is a medical term that refers to a condition characterized by the production of an abnormal amount of white blood cells, such as lymphocytes, eosinophils, or basophils, in the blood stream. This can occur in response to an allergic reaction or an infection, and may be accompanied by other symptoms such as joint pain, fever, and skin rashes.
Leucomaine
Leucomaine is a name of a type of plant, specifically a species of Camellia. It is also known as "White Tea" due to the pale white color of the young leaves and buds. The term is often used to describe a type of green tea that is harvested before the leaves fully open, resulting in a light, delicate flavor and aroma.
Leucomelanous
Leucomelanous refers to a type of skin gradually becoming light-colored or fair due to a decrease in the production of melanin, often caused by exposure to the sun. In humans, it can lead to sunburn and increased risk of skin cancers.

Leucoplast
A leucoplast is a type of plastid found in plant cells, which is involved in the storage of starch, lipids, or proteins. Unlike chloroplasts, which contain chlorophyll and are responsible for photosynthesis, leucoplasts do not contain chlorophyll and are not involved in photosynthesis. Therefore, they are referred to as "leuc-" meaning "white" or colorless, as they do not contain the green pigment chlorophyll.
Leucoplastid
Leucoplastid is a type of organelle found in plant cells. It is a non-pigmented plastid, meaning it does not contain chlorophyll, and is responsible for storing starch, proteins, and other organic compounds. Leucoplastids are found in cells that do not undergo photosynthesis, such as roots, stems, and leaves, and are also present in non-photosynthetic tissues like seeds, tubers, and fruits.
Leucoplastids
Leucoplastids are non-pigmented plastids found in the cells of plants, algae, and some bacteria. They are responsible for starch and protein synthesis, and play a crucial role in the photosynthetic and metabolic processes of these organisms. In other words, leucoplastids are the starch-making factories within plant cells, producing and storing starch for energy purposes.
Leucoplasts
Leucoplasts are any of the non-pigmented plastids found in plants and some algae. They are organelles that play a crucial role in plant metabolism, specifically in the synthesis and storage of starch, proteins, and other organic compounds. Leucoplasts are found in the cells of leaves, stems, roots, and other plant tissues, and are often found in large quantities. In contrast, chloroplasts are pigmented organelles found in plants that contain the pigment chlorophyll, which is essential for photosynthesis.
Leucoptera
Leucoptera refers to a type of pale-colored moth, particularly the genus of moths in the family Lyonetiidae. The name "Leucoptera" comes from the Greek words "leukos," meaning "white," and "ptera," meaning "wings."
