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

Cellulose

Chloroplasts


Plant Cell

  • Cellulose = carbohydrate found in cell walls

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


Cell wall

Chloroplast

Large vacuole

PLANT CELL


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)


Nucleus

Cell

Membrane

ANIMAL PLANT


Control center for plant and animal cells:

This organelle controls cell activities and reproduction


Nucleus

Nucleolus=

“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:

nucleus


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?


Lysosome:

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:

ATP
