Cells Part 2

CELLSOrganelles

Cells

Prokaryote- most basic cells. Have no internal membranes. NO Nucleus- just a nucleoid where the DNA hangs out.

Most prokaryotes are single celled organisms (unicellular).

Cells

Eukaryotes- have membrane bound organelles (mainly the nucleus)

multicellular

Organelles

Nucleus- where DNA is housed Control center

Organelles

Cell membrane- regulates the movement in and out of the cell ‘shell’ or ‘skin’

Organelles

Cell wall- hard protective barrier around the cell membrane, gives support Only found in plants

Organell

Vauole- fluid filled sac. Helps hold shape and provide water.

Organelles

Endoplasmic reticulum- folded tubes that move things around the cell

Organelles

Golgi body- makes and packages proteins delivered by the ER

Organelles

Mitochondria- produce energy (burn food for energy) ‘Powerhouse’ of the animal cell

Organelles

Chlorplasts- produce energy for plant cells Powerhouse of plants (green)

Organelles

Ribosomes- make proteins Tiny circular dots. Can be alone or on the ER.

Organelles

Lysosomes- break down food and old organelles ‘stomach’ of a cell

Organelles

Cytoplasm- provides cushion for the organelles ‘gel’ in the cell

Questions

?

Definition Assignment due D+1(approx 30 minutes)

(15 pts) Use 3 different websites to find the definitions of each Organelle. Write the your definitions in Word, include the site URLs that you used.

(5 pts) With each organelle definition, include whether that organelle is present in prokaryote or eukaryote, plant or animal.

(10 pts)And give a short explanation of how each works/what it does in your own words.

Email your word document to me.

Cell Creation Assignmentdue D+2 (approx 30 minutes)

Create a prokaryote cell and a eukaryote cell, both animal and plant. This can be done by hand and uploaded or created on the computer.

Grades- (30 pts) Approximate, based on bottom bullet A: 3 cells, clearly labeled with color and all defined

words B+: 3 cells, has all parts, clearly labeled, not colored B- 2 cells, has all parts, clearly labeled with words and color C: 2 cells, has all parts, clearly labeled, not marked by color D: 2 cells, has all parts, not clearly marked or 100% labeled F: one cell only

Missing 10% of major parts drops a letter grade.

Extra Creditdue day of Test

(+15 pts) For extra credit, create a diagram that shows how all the cell parts are connected/work together. Examples include a flow chart, an explanatory paragraph, or a short video clip/ illustration.
