Transcript cytoskeleton

KEY CONCEPT Eukaryotic cells share many similarities.
cytoskeleton
nucleus
endoplasmic
reticulum
ribosomes
Golgi
complex
vesicles
mitochondria
vacuole
lysosomes
centrioles
cell wall
chloroplast
 Cells have an internal
structure.
 The cytoskeleton has
many functions.
 supports and shapes
cell
 provides strength
 Helps 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.
