7th Science - Cells Vocab Flashcards
Group of different tissues working together to perform a job.
Organs
Group of similar types of cells that work together to carry out a specific job.
Tissues
The process of when cells become different cells.
Cell Differentiation
An organic compound made of chains of organic glucose.
Cellulose
The movement of substances through a cell membrane without using the cells energy.
Passive Transport
A molecule that forms when long chains of molecules called nucleculdes join together.
Nucieic Acids
The diffusion of water molecules only through a membrane.
Osmosis
The movement of molecules through a cell membrane that uses the cells energy.
Active Transport
A series of chemical reactions that convert light energy, water, and carbon dioxide into the food energy molecule called glucose and oxygen.
Photosynthesis
A membrane-bound organelle that uses light energy and makes food-a sugar called glucose-from water and carbon dioxide in a process called photosynthesis.
Chloroplasts
A series of chemical reactions that convert the energy in food molecules into a usable substance called ATP.
Cellular Respiration
A liquid part of a cell inside the cell membrane; contains salts and other molecules.
Cytoplasm
A flexible covering that protects the inside of the cell from the environment.
Cell Membrane
Part of a Eukaryotic cell that directs the cell activity and contains generic form of information called DNA.
Nucleus
A stiff structure outside the cell membrane that protects the cell from attacks from viruses and other harmful organisms.
Cell Wall
