Cells Flashcards
Where does chemical reaction take place?
Cytoplasm
What is the function of Rigid Cell wall?
It supports the cell and strengthens it.
What is the function of the Nucleus?
Contains genetic material that controls the activities of the cell.
What are Chloroplasts?
Chloroplasts are organelles and photosynthesis takes place in there.
What are Cells?
Building block for all living things.
What is mitochondria?
mitochondria is where aerobic respiration takes place.
What are Cell Walls?

What is a Ribosome?
Where protein synthesis takes place.
What is a permanent vacuole?
Only in plant cells; contains cell sap.
What are Eukaryotic?
A cell that has its DNA in a nucleus.
What are Prokaryotic?
A cell without a nucleus.
What is Plasmid?
Small loop of DNA (only in prokaryotic cells like bacteria)
What is the function of photosynthesis?
to convert solar energy into chemical energy and then store that chemical energy for future use.
Meaning of cell differentiation?
The process by which a stem cell becomes specialised.
Equation for magnification
Magnification= Image size
divide
Actual size
Function of mitosis
For growth and to replace worn out cells.
What is mitosis?
Mitosis is a process where a single cell divides into two identical daughter cells.
Definition of nerve cells.
A type of cell that receives and sends messages from the body to the brain and back to the body.
What are stem cells?
Stem cells are an undifferentiated cell that has the ability to differentiate into a specialised cell.
What is the Meristem?
Meristem is the part of the plant that contains stem cells.
Diffusion
The movement of particles from area of high concentration to low concentration.
Osmosis definition
The movement of water molecules across a partially permeable membrane, from a dilute to a more concentrated solution.
