Parts of the Plant Cell

h

Golgi apparatus

A folded organelle that combines proteins made by the endoplasmic reticulum and delivers them to the rest of the cell and outside the cell.

Mitochondria

The powerhouses of the cell. these organelles break down food particles and release their stored energy. the cell uses this energy to fuel all of its activities.

Vacuole

A large organelle that stores excess food, waste, and other substances. Each vacuole is surrounded by a membrane.

Cytoplasm

Jelly-like material that fills the cell and surrounds the organelles. Food and oxygen move through the cytoplasm to the organelles.

Endoplasmic reticulum

A folded organelle that makes proteins.

Ribosomes

Tiny organelles that help make proteins. There are many of these organelles in the cytoplasm

Cell membrane

The thin covering that holds cytoplasm and the organelles inside the cell and controls the passage of materials in or out of the cell.

Cell wall

Found in plant cells but not in animal cells. The rigid structure that surrounds that surrounds the cell membrane. It provides the cell with strength and support. Materials pass in or out of the cell through pores in the cell wall.

Nucleus

A large organelle that is easy to see under magnification. It controls the activities of the cell, such as growth.

Chloroplasts

Membrane-bound organelles that contain a green substance (pigment) called chlorophyll. In a process called photosynthesis, chlorophyll uses the Sun's energy to convert carbon dioxide and water into sugar (food) and oxygen. Chloroplasts are found in plant cells but not in animal cells.
