Mo3-L1b: Parts of a Cell

The Inside of a Cell
The inside of a cell is mainly water. Mitochondria are organelles that break down food
and release energy.
This makes it easier for the substances to move
around inside a cell, gives cells their shapes, and
helps keep the structures inside a cell organized.
The liquid part of a cell inside the cell membrane is
called the cytoplasm.

Chloroplasts capture light energy and convert it into
chemical energy in a process called photosynthesis.

Proteins are made on the surface of ribosomes that
are in the cytoplasm of both prokaryotic and
eukaryotic cells.

The information that controls all of a cell’s activities
is stored in its genetic material, called DNA

The information in DNA is transferred to another An organelle called the Golgi apparatus packages
nucleic acid called RNA, which gives cells proteins into tiny organelles called vesicles, which
instructions about which proteins need to be made. transport proteins around a cell.
RNA Template Other molecules are stored in organelles called
vacuoles.
