Q

What is a Vacuole and is it both

A

Both
Plays role in intercellular digestion and cellular waste products
In animal cells they tend to be small
In plants they tend to be large and play several different roles
Storing nutrients and waste products, helping increase cell size during growth,also it regulates turger pressure

Q

Cell Wall

A

Plants only
A protective cell wall made up of polysaccharide
In higher plant cells the polysaccharide is usually cellulosel
Fluid collects in the vacuole and presses against the cell wall this is reason for crispness of fresh vegetables

Q

Chloroplast

A

Plants only
Are specialized organelles that are found in higher plant cells
These organelles contain the cells chlorophyll which is responsible for the green colour on the leaves witch is necessary to be able to absorb energy from sunlight
