Eukaryotic Cell Structures & Functions

Ch7.3 (Ch7 Vocabulary Guide)


An organelle is l.jpg

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 l.jpg

What are some functions that occur within a cell?

Digestion Excretion

Transportation of cell’s products

Storage Protection

Division Mobility

Respiration or Photosynthesis


Slide4 l.jpg

Organelles found only in Plants:

Cell Walls

Cellulose

Chloroplasts


Plant cell l.jpg

Plant Cell

  • Cellulose = carbohydrate found in cell walls

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


Slide6 l.jpg

Cell wall

Chloroplast

Large vacuole

PLANT CELL


Found in both plant and animal cells l.jpg

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)


Slide9 l.jpg

Nucleus

Cell

Membrane

ANIMAL PLANT


Slide10 l.jpg

Control center for plant and animal cells:

This organelle controls cell activities and reproduction


Slide11 l.jpg

Nucleus

Nucleolus=

“little nucleus”

Animal Cell


Slide12 l.jpg

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 l.jpg

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

Control center for plant and animal cells:

Chromatin = protein composing chromosomes


Slide14 l.jpg

Red Blood Cells have no:

nucleus


Slide15 l.jpg

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 l.jpg

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

Endoplasmic Reticulum

ROUND Ribosomes


Slide17 l.jpg

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


Slide18 l.jpg

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 l.jpg

Endoplasmic Reticulum

“Rough” with Ribosomes

for protein synthesis

“Smooth” =

Membrane “highway”

For transport of materials


Slide20 l.jpg

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 water why are plant vacuoles larger than animal vacuoles l.jpg

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

Plant Vacuole


Slide22 l.jpg

Some Animal cell vacuoles pump water out by contracting:

Do you see 2 Contractile vacuoles

in this Paramecium?


Slide23 l.jpg

Lysosome:

Contains digestive enzymes

Breaks down large molecules


Chloroplast absorbs light changes light energy into chemical energy for photosynthesis green sacks l.jpg

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


Slide25 l.jpg

The power house of the cell:

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

ATP
