Explain 1 difference between a prokaryotic cell and a eukaryotic cell.

What organelles are found in Eukaryotic cells?


Review: Cell Types

Prokaryotic Eukaryotic



Noticing Deeply: Eukaryotic Cells


Plant Cell Vs. Animal Cell

Plant Cells have a square shape

Animal cells have a round shape



Cell Organelles and their Functions


• The little cell parts are called organelles.

Each organelle does a specific job for the cell.

What are organelles?


Organelles Found in Both Plant and Animal CellsPlasma membrane (cell membrane)CytoplasmRibosomesEndoplasmic reticulumNucleusVacuolesMitochondria



Organelles and their function





Cell Membrane

The cell membrane protects the cell and allows some things in and out of the cell.



Cytoplasm

Cytoplasm is the watery gel (Jello!) inside a cell….it’s goop! It holds the ORGANelles.



Mitochondria Mitochondria is an ORGANelle that releases

energy from food. Every type of cell has a different amount of

mitochondria. There are more mitochondria in cells that have to perform lots of work, for example - your leg muscle cells. Other cells need less energy to do their work and have less mitochondria.



Nucleus

The nucleus controls the cell. It is the largest organelle in the cell and

contains the cell’s DNA.



Chromosomes Chromosomes are inside the nucleus and

are made of genes (DNA). Genes decide the cells traits and activities

(heart cell, eye cell - such as color).



***Cell Differentiation

Every cell has the same exact DNA but… Each kind of cell has a DIFFERENT job to

do…it is specialized.

I am a heart cell! I am a

skin cellI’m a

Prison Cell!



Vacuoles

Vacuoles are storage spaces in the cell where food and chemicals are stored



Endoplasmic Reticulum

It is a network of membranes throughout the cytoplasm of the cell.

It helps to move materials around the cell.



Golgi apparatus

It is organelle in the cell that is responsible for sorting and correctly shipping the proteins produced in the ER.

They also package proteins to be moved out of the cell.



RibosomesOrganelles that help in the synthesis (the

making) of proteins.

Some organelles are found only in plant cells





Cell Wall

Cell Walls are only in plant cellsThey make the cell strong and rigid

and give it its square shape.



Chloroplasts

Chloroplasts are only in plant cellsThey contain chlorophyll, which helps make

energy/food from sunlight through photosynthesis.

Chlorophyll is green in color.

See the Chloroplast?



Organelle found only in animal cells.





Lysosomes

• Lysosomes contain chemicals that help break down food molecules, wastes, and worn out cell parts.

The lysosomes are stained RED!



What’s the Difference? (Turn and Talk)So what are two things that Plant cells

have that animal cells don’t?

?

Chloroplasts, vacuoles, & Cell Walls

Activity

Identify the Cell Organelles

Using your notes work with your partner to find the organelle that matches the riddle.
