Eukaryotic Cell Structures & Functions

Ch7.3 (Ch7 Vocabulary Guide)

an organelle is
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
What are some functions that occur within a cell?

Digestion Excretion

Transportation of cell’s products

Storage Protection

Division Mobility

Respiration or Photosynthesis

slide4

Organelles found only in Plants:

Cell Walls

Cellulose

Chloroplasts

plant cell
Plant Cell
  • Cellulose = carbohydrate found in cell walls
  • Cell Wall= forms rigid outer structure, made of cellulose (fiber)
slide6

Cell wall

Chloroplast

Large vacuole

PLANT CELL

found in both plant and animal cells
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

Nucleus

Cell

Membrane

ANIMAL PLANT

slide10

Control center for plant and animal cells:

This organelle controls cell activities and reproduction

slide11

Nucleus

Nucleolus=

“little nucleus”

Animal Cell

slide12

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

Control center for plant and animal cells:

Chromatin = protein composing chromosomes

slide15

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

Endoplasmic Reticulum

ROUND Ribosomes

slide18

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
Endoplasmic Reticulum

“Rough” with Ribosomes

for protein synthesis

“Smooth” =

Membrane “highway”

For transport of materials

slide20

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

Plant Vacuole

slide22

Some Animal cell vacuoles pump water out by contracting:

Do you see 2 Contractile vacuoles

in this Paramecium?

slide23

Lysosome:

Contains digestive enzymes

Breaks down large molecules

chloroplast absorbs light changes light energy into chemical energy for photosynthesis green sacks
Chloroplast= absorbs light, changes light energy into chemical energy for photosynthesis = GREEN Sacks
slide25

The power house of the cell:

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

ATP
