centrioles

cell wall

chloroplast

Cells have an internal structure.The cytoskeleton has many functions.supports and shapes cell

provides strengthHelps in cell division

aids in cell movement

helps position and transport organelles

Several organelles are involved in making and processing proteins.The nucleus stores and protects the genetic information, DNA.

Several organelles are involved in making and processing proteins.Many processes occur in the endoplasmic reticulum.Help make proteins & lipids Help breakdown drugs and alcohol

Several organelles are involved in making and processing proteins.There are two types of endoplasmic reticulum. rough endoplasmic reticulum

smooth endoplasmic reticulum

Several organelles are involved in making and processing proteins.Ribosomes link amino acids to form proteins.

Several organelles are involved in making and processing proteins. The Golgi complex processes, sorts, and delivers proteins

Several organelles are involved in making and processing proteins.Vesicles are membrane-bound bags that hold materials.

Other organelles have various functions.Mitochondria supply energy to the cell.

Other organelles have various functions.Vacuoles are fluid-filled bags that hold materials.

Other organelles have various functions.Lysosomes contain enzymes to digest (break up) invaders or worn-out cell parts.

Other organelles have various functions.Centrioles help to form cilia and flagella for movement; play a role in cell division (mitosis)

Plant cells have cell walls and chloroplasts.A cell wall provides rigid support.

Plant cells have cell walls and chloroplasts.Chloroplasts convert solar energy to chemical energy.
