Task: Write a comparison of animal and plant cells
While plant and animal cells appear to be different, they have some similar features.
Both kinds of cells contain a nucleus – which can also be known as the “brains” or the “control centre” of the cell. The nucleus of a cell contains most of its genetic material and is responsible for controlling all of the cell’s activities through gene expression.
Both plant and animal cells also have structures called chromosomes. They are located inside the nucleus. The chromosomes are the genetic material responsible for the reproduction of cells.
Outside the nucleus of both plant and animal cells are structures called ribosomes. These ...view middle of the document...
Vacuoles are important for storage in a cell; they store the food, nutrients and enzymes that a cell needs to function as well as store and remove unwanted substances like toxic materials and waste from the cell.
Although plants and animal cells share many similarities, there are some additional structures that plant cells have which animal cells don’t.
The plant cell, for example, contains a cell wall. The cell wall is made up of cellulose and assists a plant cell to maintain its shape. The cell wall is located outside the cell membrane of a plant cell and is also responsible for the prevention of the rupture of a cell when (excess) water enters it.
Cellulose is a substance which is found in the cell wall of a plant cell. Simply put, cellulose is cell sugar. Its main function is to support the plant – to keep the plant rigid and prevent it from slopping over.
A further difference between plant and animal cells is that plant cells contain a nuclear membrane. This structure has a similar role to the cell membrane. The nuclear membrane surrounds the nucleus and controls what substances enter and...
