You need to identify the different parts
of a typical animal cell and relate the
parts to the functions.
parts of animal cell:
cell membrane, cytoplasm, nucleus

According to the cell theory, proposed over
150 years ago:
Most cells are very tiny and can only be seen withthe aid of a microscope. A human body iscomposed of billions of cells!
The cells in the human body consist of bloodcells, skin cells, brain cells and many others andeach type of cells has different functions.
Despite their differences, most cells in livingorganisms have similar structures and functions.

The nucleus is located in the cytoplasm of thecell.
It controls and regulates all cell activities. It isthe "control center" of the cell and it contains
the cell's DNA.
It has a similar function to the brain of thebody which is helping to control eating,movement, and reproduction.

You need to identify the different parts of a
typical plant cell and relate the parts to the
functions.
parts of plant cell:
cell wall, cell membrane, cytoplasm,
nucleus and chloroplasts

Chloroplasts are onlyfound in plant cells. Theyare responsible forphotosynthesis.
Every green plant yousee is working to convertthe energy from the suninto sugars during theprocess ofphotosynthesis.
Plants are the basis of alllife on Earth. They makesugars, and the by-product of
photosynthesis is theoxygen that we breathe.
Chloroplasts are greenbecause of the pigment
chlorophyll.

Inside the cell, there isa large fluid-filledspace called thecytoplasm.
It is a jelly-likesubstance composedof mainly water as wellas substances likedissolved nutrients.
The cytoplasm is foundin both plant andanimal cells, filling thespace between thenucleus and the cellmembrane.

The nucleus is found inboth plant and animal
cells.
It is located in thecytoplasm of the cell.
It controls and regulatesall cell activities. It is the"control center" of thecell and it contains thecell's DNA.
It has a similar functionto the brain of the bodywhich is helping tocontrol eating, movement,
and reproduction.

Differences between Plant and
Animal Cells
Plant Cell Animal CellPlant cells contain
chloroplasts to make
food from solar energyduring photosynthesis.
Underground parts of
plants usually do not
contain chloroplasts.
Animal cells do not
contain chloroplasts.
Plant cells contain cell
wall.
Animal cells do not have
cell wall.
