Maintenance In Living Things Flashcards
The organism can synthesize organic substances from inorganic substances from the environment
Autotrophic nutrition
The organism must in just needed organic substances from other organisms in the environment
Heterotrophic nutrition
The most common type of autotrophic nutrition
Photosynthesis
Equation for photosynthesis
Carbon dioxide + water —light energy—> glucose + water + oxygen
Heterotrophic nutrition involves the processes of
Ingestion (taking in food) , digestion, and egestion (discharging waste)
The particles tend to spread out from an area of high concentration to an area of low concentration
Diffusion
Involves the movement of particles through a membrane with the use of energy by the cell
Active transport
Involves the movement of particles through a membrane without the use of energy by the cell
Passive transport
Large dissolved molecules can pass through a cell membrane by the process of
Pinocytosis
The process by which a cell engulfs large undissolved particles by falling around them in and closing them in a vacuole
Phagocytosis
The diffusion of water
Osmosis
Cellular respiration requires the presence of free oxygen in the process is known as
Aerobic respiration
In a few kinds of organisms free oxygen is not used in the process is known as
Anaerobic respiration or fermentation
Equation for respiration
Glucose + oxygen –enzymes–> water + carbon dioxide + ATP
Specialized for the transmission of impulses from one part of the body to another
Nerve cells or neurons
