What do cells consist of , and what do they allow cells to do
Numerous structures , that allow cells to carry out functions
What do cells form
Basic units of plant an animals
Why do plant and animal cells have similarities and differences
Due to the different functions performed by the cells
Name the structures found in cells
Cell wall, cell membrane, cyptoplasm, vacuole, nucleus, chloroplast, mitochondrion,
Where is the cell wall found
In plant cells
What are cell walls made of
A substance called cellulose
What is the main function of a cell wall
To give the cell shape and support
What is the cell wall described as and why
Permeable , as liquids and dissolved substances pass through the cell wall freely
Where is cell membrane found
Found in both plant and animal cells
What does the cell membrane form
Outermost boundary
Where does the cell membrane lie in plant cells
Against the inner part of cell wall
In animal cells what does the cell membrane form
It forms the outermost boundary
Describe the cell membranes layer
Thin, flexible layer that keeps contents from escaping and mixing with surroundings
What is the cell membrane described as and why
Partially permeable as it controls what enters and leaves the cell
Do all cells have a cell membrane
Yes
Where is cyptoplasm found
In both plant and animal cells
What is cyptoplasm
Liquid containing chemicals needed for functioning of cell
Where is a large vacuole found
Found in plant cells
What diss a vacuole consist of
Fluid known as cell sap
What do cell saps consist of
Mainly water with many dissolved substances
What surrounds the fluid in a vacuole
A membrane called the tonoplast
What does the vacuole in plants help
Helps water move into the cell, keeps cell firm and keeps its shape (turgor support)
Do animal cells have vacuoles
They may have small vacuoles , or not even a vacuole at all
Where is nucleus found
In bite animal and plant cells
