Functions
What does a cell wall do?
-Provides structural support.
-Protects the cell.
-Controls the amount of water in and out of the cell.
What does the endoplasmic reticulum do?
-Make proteins
-Make fats
-Break down waste
What does a lyosome do?
-Digests worn-out organelles, engulfed viruses or bacteria and other wastes.
What does a cell membrane do?
-Holds cells together.
-Allows nutrients in.
-Allows waste out.
What does a ribosome do?
-Ribosomes read messages from the nucleus to make specific proteins.
What do animal cells have
-have more, yet smaller vacuoles
-do not have a cell wall
-have lysosomes
-do not have chloroplasts
What does a cytoplasm do?
-Stores waste until the cell can get rid of it.
-Sends oxygen and nutrients to other parts of the cell.
-Holds organelles in place.
What does a Golgi body do?
-Modifies proteins further so they are ready to be shipped To other organelles
What do plant cells have?
-have larger, but fewer vacuoles
-have a cell wall
-do not have lysosomes
-have chloroplasts
What does the nucleus do?
-Stores chromosomes
-DNA determines specific characteristics of an individual, -Repairs cells and creates new cells.
-Brain of the cell.
What does the mitochondria do?
-The powerhouse of the cell.
-Provides cells with energy by using oxygen to change sugar into energy.
What do vacuoles do?
-Store water, nutrients and other substances for later use by the cell.
What does a chloroplast do?
-Use sunlight to make food through a process called photosynthesis.
