Eukaryotic Cell Structures & Functions

Ch7.3 (Ch7 Vocabulary Guide)

An Organelle Is:

A minute structure within a plant or animal cell that has a particular job or function.

What are some functions that occur within a cell?

Digestion Excretion

Transportation of cell’s products

Storage Protection

Division Mobility

Respiration or Photosynthesis

Organelles found only in Plants:

Cell Walls



Plant Cell

  • Cellulose = carbohydrate found in cell walls

  • Cell Wall= forms rigid outer structure, made of cellulose (fiber)

Cell wall


Large vacuole


Found in both Plant and Animal Cells

Organelles that surround cells for support:

Cell Membrane= Semi-permeable,

controls what enters and leaves the cell, outer containment envelope.

Cytoskeleton =

gives structure to a cell (#14)





Control center for plant and animal cells:

This organelle controls cell activities and reproduction



“little nucleus”

Animal Cell

Control center for plant and animal cells:

Nucleus = control center for activities & reproduction, DNA & chromosomes housed here.

Nucleolus = contains and makes RNA

Chromosome = coiled DNA: contains instruc-tions for char-acteristics of an organism.

Control center for plant and animal cells:

Chromatin = protein composing chromosomes

Red Blood Cells have no:


Control center for plant and animal cells:

Nuclear membrane = protects and controls what goes in and out of the nucleus

(notice the nuclear pores in this picture of a nucleus)

Ribosomes= Site of Protein Synthesis on the E.R.

Endoplasmic Reticulum

ROUND Ribosomes

Cytoplasm:or cytosol, = gel surrounds the organelles, contains enzymes

ER = Endoplasmic Reticulum:

specializes in the production & transport of lipids and membrane proteins

Rough ER has ribosomes Smooth ER lacks ribosomes

Ribosomes: Whereproteins are manufactured.

Endoplasmic Reticulum

“Rough” with Ribosomes

for protein synthesis

“Smooth” =

Membrane “highway”

For transport of materials

Golgi Bodies (aka Golgi Apparatus):

where cell products are modified and packaged in vesicles for export from the cell.

“Sacks” for making

& storing Secretions

Vacuole = storage for food and waterWhy are plant vacuoles larger than animal vacuoles?

Plant Vacuole

Some Animal cell vacuoles pump water out by contracting:

Do you see 2 Contractile vacuoles

in this Paramecium?


Contains digestive enzymes

Breaks down large molecules

Chloroplast= absorbs light, changes light energy into chemical energy for photosynthesis = GREEN Sacks

The power house of the cell:

Mitochondria = site where energy is released from glucose in the form of:
