Basic Sciences - Zoology & Botany

a large group of animals characterized by the possession of a backbone or spinal column, including mammals, birds, reptiles, amphibians, and fishes

species that do not possess or cannot develop a spinal column, such as an arthropod, mollusk, etc.

a class of animals to which humans, cows, lions, etc. belong, have warm blood, fur or hair and typically produce milk to feed their young

a class of animals to which crocodiles, lizards, etc. belong, characterized by having cold blood and scaly skin

any cold-blooded animal with the ability to live both on land and in water, such as toads, frogs, etc.

an animal that feeds on the flesh of other animals

any animal that only feeds on plants

producing eggs that develop and hatch outside the body

(of an animal) giving birth to live offspring that have developed from eggs inside the mother's body

(of animals) giving birth to developed babies instead of laying eggs

the controlled maintenance of a specific temperature; fostering optimal conditions for the development of organisms, processes, or materials

a natural reaction or behavior that occurs automatically, without conscious thought or reasoning

to secrete or produce milk from the mammary glands, typically referring to the production of milk by a female mammal, especially a human mother

to bring up partially digested food from the stomach back into the mouth, often to feed young or as part of the digestive process

(of plants or animals) found in many different regions and climates throughout the world

(ecology) a group of different species living in the same area and interacting with one another

(biology) the slow and gradual development of living things throughout the history of the earth

a group that animals, plants, etc. of the same type which are capable of producing healthy offspring with each other are divided into

a taxonomic rank below species that represents a distinct population within a species, exhibiting consistent differences from other populations

a small, membrane-bound sac within a cell, involved in the transport, storage, or release of substances

a green pigment found in all green plants and cyanobacteria that is responsible for the absorption of the sunlight needed for the photosynthesis process

a plant cell organelle that uses sunlight to produce energy and make glucose through photosynthesis

a process in green plants during which the plant synthesizes using water and carbon dioxide

to reproduce and produce offspring through natural methods

(botany) the process by which a seed or spore begins to grow and develop into a new plant

(biology) the process of producing plant seeds by transferring a powdery substance from one plant to the other
