Study Notes

Cell Parts and Functions

All living things are made up of cells.
The nucleus is the control center of the cell and contains DNA.
The cell membrane is a thin wall surrounding the cell that allows useful substances to enter and forces out waste products.
The cell wall provides support, structure, and protection for plant cells.
Mitochondria are in both plant and animal cells and are known as the "powerhouse" of the cell because they convert food into usable energy.
Ribosomes are found in both animal and plant cells and create proteins needed for the cell to function.
Vacuoles are storage bubbles found in both animal and plant cells but are much larger in plant cells. They store water, nutrients, chemicals, and waste.
Chloroplasts are found only in plant cells and convert sunlight, water, and carbon dioxide into food for the plant through photosynthesis.
Cytoplasm holds the parts of the cell in place and protects them from damage.

Differences between Animal and Plant Cells

Plant cells have a cell wall, chloroplasts and larger vacuoles while animal cells do not.
Both animal and plant cells have a cell membrane, nucleus, mitochondria, and ribosomes.

Cell Membrane

The cell membrane allows some substances to enter the cell while blocking others, ensuring balance for the cell.
