What Does a Cell Look Like?
Membrane
Cytoplasm
Chromosomes
Nucleus
Each cell in your body is as alive as you are. It “breathes,”
takes in food, gets rid of wastes, reproduces, and in
time, dies.
Cells have different shapes, according to the work they do.
Cells might look like cubes, rods, snowflakes, or even blobs
of jelly.
Every cell’s outer layer is a thin skin called a membrane.
It has openings to let materials in. Most of the cell is made
of a jellylike fluid called cytoplasm. Cytoplasm contains
the things that a cell needs to live.
Near the center of the cell is a small area that is called the
nucleus. The nucleus is the “brain” of the cell. The nucleus
contains tiny threadlike structures called chromosomes.
Inside each chromosome are about 1,000 genes.
Genes are like small carriers of information. They tell about
a person’s gender or sex, the color of your hair and eyes,
the shape of your hands, and many other things.
