Characteristics of Living Organisms (1.1-1.5)

Autotrophs

: Living organsims that synthesize organic molecules from simple inorganic substances (through photosynthesis)

→Non celluar

and consist of genetic material surrounded by a protein coat.

Binomial Nomanclature

: Specific naming system of giving names to living organisms.

Viruses

are NOT considered living organsims because they do not complete these processes.

Excretion

: Removal of toxic materials, waste products from metabolic processes or substances in excess.

Sensitivity

: Detection of a stimulus and ability to respond.

Classification

is used to group species.

Respiration

: Biochemical reaction in cells that breakdown nutrient molecules for metabolism.

Nutrition

: Intake of substances required for growth and to provide energy.

Movement

: when an organism or part of it changes its place /position.

Growth

: Permanent increase in cell size, number or complexity.

Reproduction

: Creation of offspring of the same species as the parents.

Anatomy

: Study of internal characteristics.

Morphology

: Study of external characteristics.

→ Algae

: No leaves, roots or stems.

Species

: group of arganisms that can be bred to reproduce fertile offspring.

Movement

__:when an organism or part of it changes its place/position
