Organization of Living Matter
Composed of chemical substances
What are biomolecules?
A thin layer that separates the cell from the external environment
What is the membrane?
When different types of cells are created and cell groups specialise to perform different tasks
Perform the functions of nutrition, reproduction, and interaction
What are systems?
The systems that coordinate all the systems in the body
Formed by the ensemble of systems that function in a coordinated way
What is an Organism?
The basic structural and functional units that form our organism
What are cells?
What is a tissue?
Four systems that intervene in nutrition
What are digestive, respiratory, circulatory, and excretory?
Provides the oxygen needed to extract the energy in nutrients
What is the respiratory system?
Living things that have many cells which have different structures and functions
What are multicellular organisms?
Where the majority of vital chemical reactions take place
What is the cytoplasm?
Epithelial, connective, muscle, nervous
What are the types of tissues?
the group of processes that allow us to use and transform the substances we need to stay alive
What is nutrition?
This takes place due to a response to stimuli via the nervous system and complex regulation of the endocrine system
What is reproduction?
What is an organ?
The passage of small molecules from an environment where there is a greater concentration of molecules to one where there is a lower concentration of molecules
What is diffusion?
Types of tissue that accumulates fat and functions to be an energy reserve
What is adipose tissue?
Words for male and female gametes
What are spermatozoids and eggs?
A system that detects stimuli and responds by sending nerve impulses to parts of the body (which activate or stop some functions)
What is the nervous system?
Living things obtaining their own organic matter by feeding on other living things
What is heterotrophic nutrition?
The type of exchange of substances that occurs when the concentration of substances is less in the exterior of the cell
Tissue that has the ability to contract and is responsible for the organism's movement
What is muscle tissue?
A system that secretes substances that affect an organism in different ways
What is the endocrine system?
A consequence of a response of the nervous system to different stimuli
What are movements performed by the skeletal and muscular systems?
