Basic Sciences - Zoology & Botany

(zoology) an animal with a backbone and a skull enclosing a brain

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

a warm-blooded vertebrate animal whose females produce milk to feed their young and that typically has hair or fur

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 tendency or ability to behave or react in a particular way without conscious thought or learning

(physiology) to produce milk from the mammary glands to feed offspring

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

(ecology) found or living in most parts of the world

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

the process by which populations of living organisms change genetically across successive generations

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

(biology) a distinct group within a species, often formed by geographic separation and showing slight physical or genetic differences

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
