What is active transport?
The movement of substances from a dilute solution to a more concentrated solution against a concentration gradient
What is Active Transport
The movement of substances from a dilute solution to a more concentrated solution against a concentration gradient
What is Algae
Simple aquatic organisms that make their own food by photosynthesis
What are Alveoli
Tiny air Sacs in the lungs that increase surface area for gaseous exchange
What is Bacteria
Single - celled prokaryotic organisms
What is the Cell Membrane
The membrane around the contents of a cell that controls what moves in and out
What is the Cell Wall
The rigid structure around the plant and algal cells that is made from cellulose and strengthens the cell
What is Cellulose
The complex carbohydrate that makes up plant and algal cell walls and gives them strength
What is Chlorophyll
The green pigment contained in chloroplasts
What are Chloroplasts
The organelles in which photosynthesis take place
What is Cytoplasm
The water-based gel in which the organelles of all living cells are suspended
What is Diffusion
The spreading out of particles of any substance in a solution, or particle in gas
