Transcript Description

Cell Wall
Function:
supports & protects cell
Cell membrane
Description:
•outer layer of animal cell
•inside cell wall of plant
•elastic & flexible
•contains pores
Function of cell membrane
Controls movement of
materials into & out of
cell
Mitochondria
• “powerhouse of the cell”
• makes energy as ATP
Vacuoles
Description:
large, round water-filled sac
in cytoplasm
Vacuole function
Stores food, water & wastes
Lysosomes
Description:
•small, round sacs in cytoplasm
•contain digestive enzymes
Function:
•breaks down food,
dead cells, old cell
parts
Chloroplast
Description:
•green, oval-shaped structures
•holds chlorophyll
Cytoplasm
Function:
•moves organelles &
materials throughout cell
Nucleus
Description:
•large, oval structure in center of cell
•surrounded by nuclear membrane
•holds chromosomes & nucleolus
Function of Nucleus
•control center of cell
•regulates all activities
Nucleolus
Description: small dark area in
nucleus
Function: makes ribosomes
Chromosomes
Function:
•directs cell activities
•passes traits to new cells
•stores info to build protein
Endoplasmic
Reticulum
Description:
• clear tubular passageways
throughout cytoplasm
Endoplasmic Reticulum
Function:
•transports materials
throughout cell
•“transportation system”
Ribosomes
Function:
makes proteins
Description:
•surrounds nucleus
•evenly spaced pores
Function: allows materials to
pass in/out of nucleus
