Organelles & Levels of Organization

Use these slides to study for your test on Thursday!

Organelles

3

*Parts of a cell

Mitochondria

Function: ● Breaks down sugar (glucose)

to release energy

● “POWER HOUSE”

In BOTH animal and plant cells.

VacuoleFunction: ● Stores food, water, and

waste

● It is much LARGER in PLANT cells

In BOTH animal and plant cells.

Nucleus

Function: ● Controls all cell activities.

● The BRAIN of the cell

● Contains hereditary/genetic information

In BOTH animal and plant cells.

ChloroplastFunction: ● Uses energy from the sun

in a process called photosynthesis to make sugar (glucose) and oxygen.

● ONLY IN PLANT CELLS

Cell Wall

Function:

● Supports and protects

● ONLY IN PLANT CELL

Cell Membrane

Function:● Controls movement of

material in/out of the cell

In BOTH animal and plant cells.

CytoplasmFunction:● jelly-like substance that

supports and protects organelles

In BOTH animal and plant cells.

RibosomeFunction:● Synthesizes (creates)

proteins

In BOTH animal and plant cells.

Golgi BodyFunction:● Helps make and package

material to be transported out of cell

In BOTH animal and plant cells.

Levels of Organization

13

*Order of living things

CELL● ALL living things are made

of cells.

● The smallest unit of a living thing

TISSUE

A group of CELLS working together to perform a specific function (job).

ORGAN

A group of TISSUES working together to perform a specific function (job).

ORGAN SYSTEM

A group of ORGANS working together to perform a specific function(job).

ORGANISMLiving thing that can perform all processes necessary for life.

Levels of Organization● What order did you put them in?

● SMALLEST:

● 1.

● 2.

● 3.

● 4.

● 5.

● 6.

● LARGEST ^^
