Science cells flashcard

Flexible covering that protects the inside of the cell from the environment outside of a cell

A stiff structure outside the cell membrane

A fluid inside a cell that contains salt and other molecules

A network of threadlike proteins that are joined together

Specialized function

The part of a eukaryotic cell that directs cell activities and contains genetic material

A membrane bound organelle that uses light energy and makes food

Movement of substances through a cell membrane without using the cells energy

Movement of substances, from an area of higher concentration, to one of a lower concentration

The diffusion of water molecules only through a membrane

When molecules passed through a cell membrane using special proteins, called transport proteins

Movement of substances, through a cell membrane only by using the cells energy

Process during which a cell takes in a substance by surrounding it with the cell membrane

The process during which of cells vesicles release their contents outside the cell

A series of chemical reactions that convert the energy and food molecules into a usable form of energy called ATP

A process by which glucose a sugar is broken down a smaller molecules

A reaction that eukaryotic and prokaryotic cells can use to obtain energy from food when oxygen levels are low

A series of chemical reactions that convert light energy water and CO2 into the food, energy molecule glucose and give off energy
