Parts of a cell What are the functions of cell organelles? What organelles are only in plant cells?
What is an organelle? Organelles: Structures inside a cell, they all have different jobs Like organs, but small
Cells & Organelles Organelles in all cells: Cell Membrane – protects cell; let stuff in and out Nucleus – “boss” of cell; tells other organelles what to do Endoplasmic Reticulum (ER) – transport materials Golgi Body – transport materials Ribosome – make proteins Vacuole – storage for the cell Lysosome – break down food Mitochondria – changes food to energy
Animal Cell Ribosomes (protein factory) Mitochondria (Power Plant) Nucleus (Boss) Cell Membrane (barrier) Endoplasmic Reticulum (Road) Golgi Body (Road) Vacuole (Storage) Lysosome (Cleanup)
Special Organelles Cytoplasm – thick, clear liquid inside the cell Only in plant cells: Cell wall – gives plant cell a box shape Chloroplasts – capture energy from sunlight
