Life is Cellular!
TEKS
(4) Science concepts. The student knows that cells are the basic
structures of all living things with specialized parts that perform
specific functions and that viruses are different from cells. The student
is expected to:
Materials
-
Warm Up- Concept map
Quiz
-
Cell picture print out
-
Microscopes with slides of cells
-
Toothpick lab
(A) compare and contrast prokaryotic and eukaryotic cells;
Vocabulary
Learning Targets/Objectives
After the lesson students will be able to”



Discuss the difference between prokaryotic and eukaryotic
cells
Identify eukaryotic cell organelles
Analyze plant versus animal cell structures and their functions
Activities
Warm-Up- Students will work on cell structures and function
concept map quietly and independently. Warm is a review over last
nights reading for daily quiz.
7min Quiz over last nights reading (5 questions/1min) FOR A
GRADE
5-10 mins
-In 1665, Robert Hooke used an early compound microscope to
look at a thin slice of cork, a plant material.
-Cells are the basic unit of life…(Smallest functional unit)
-Similar to a car, living organisms are the cars but all the parts
(steering wheel, brakes, engine, etc) all work together to allow the car
to be. Each one is dependent upon the other.
The cell Theory:
All living things are composed of cells.
Cells are the basic units of structure and function in living things.
New cells are produced from existing cells.

Prokaryotes and Eukaryotes
- cells come in a variety of shapes and sizes
all cells are surrounded by a barrier called cell membrane and contain
DNA
Cells are classified into 2 groups based on whether or not they have a
nucleus.
The nucleus is a large membrane-enclosed structure that contains the
cell's genetic material in the form of DNA. It looks like a dark ball
under a microscope. The nucleus controls many of the cell's
activities.
Eukaryotes= with nucleus Prokaryotes= no nucleus SHOW

In groups at table: list characteristics of prokary. vs. eukaryo.
Plant vs. Animal (divide up, then have students write them down
on sticky notes and place them on the cell pictures on the wall.
Include an example of each.) [use book]
15 min
Other Notes:
Prokaryotic cells have genetic material that is not contained in a
nucleus.
- Prokaryotes do not have membrane-bound organelles.
- Prokaryotic cells are generally smaller and simpler than eukaryotic
cells.
- All prokaryotes are Bacteria.
20min
Eukaryotic cells contain a nucleus in which their genetic material is
separated from the rest of the cell.
-
Eukaryotic cells are generally larger and more complex than
prokaryotic cells.
Eukaryotic cells generally contain dozens of structures and
internal membranes.
Many eukaryotic cells are highly specialized.
Plants, animals, fungi, and protists are eukaryotes.
Components of a Cell (Organelles)
Nucleus- control center, contains DNA
Cell Membrane-out layer of the cell
Endoplasmic Reticulum – packages proteins
Ribosomes- Protein synthesis
Golgi Apparatus – modifies proteins and packages it
Lysosomes- contains digestive enzymes, break down bacteria
Mitochondria vs. Chloroplast – energy sythesis
Cytoplasm – contains most of organelles
Centriole vacuole (plants)- stores water
Classwork
Finish classwork packet 7.1 - 7.2 could have been completed as
homework to study for quiz today. If so, student receives technology
time remaining 15mins of class
Evaluation/Assesment
Students will complete an exit quiz a BrainPOP quiz on
technology.
