COMPARING CELLS
The size & shape of a cell relates to its function (job it does).

CELLS
There are two kinds of cells: Animal & PlantSome organisms are unicellular (single-celled) and some organisms
are multicellular (many cells).
All cells do three activities or things:
1. Bring materials into the cell.
2. Use the materials for life activities and
processes.
3. Get rid of waste.

NUCLEUS
Controls all cell activities
Contains the instructions for everything the cell does
These instructions are found on a material called DNA
Usually the largest organelle

CELL MEMBRANE Protective layer around
ALL cells Controls what enters and
leaves the cell For cells with a cell wall,
the cell membrane is on the inside of the cell wall
Allows water, gases (O2 & CO2), and materials into the cell & waste materials out of the cell.

CYTOPLASM
The cytoplasm is the gel-like substance that fills the entire cell.
This is where all cell activities take place.
Main ingredient: WATER

MITOCHONDRIA
Inside a chemical reaction takes place to release energy for the cell to use. This process is called CELLULAR RESPIRATION Takes in O2 and sugar; Releases energy, CO2
and H2O Energy is released by breaking down food AKA the powerhouse b/c it releases energy from
food.

ENDOPLASMIC RETICULUM
The ER transports materials around the cell. (like a conveyor belt)
Smooth ER – ribosomes not attached to ER
Rough ER – ribosomes attached to ER

RIBOSOMES
Make proteins for the cell to use
Float freely or are attached to the endoplasmic reticulum (ER)
Ribosomes are made in the nucleus

Plant cells have many of the same organelles that an animal cell does…plus
a few more _______________________

CELL WALL
found outside the cell membrane gives shape, structure, and support to
organism – does what bones do for humans!

CHLOROPLASTS This is where photosynthesis takes
place. Contains chlorophyll, a green
chemical, making the plant green. Chlorophyll absorbs the sun’s energy
to change carbon dioxide and water into sugar and oxygen.
CO2 + H2O = C6H12O6 (sugar) + O2

VACUOLES
Does the exact same thing in plant cells that it does in animal cells…only MUCH BIGGER.

All organisms need Carbon,but how do they get it?
![Page 20: Cells: Plant and Animal What is the smallest part of this living thing?](https://reader037.vdocuments.mx/reader037/viewer/2022102603/551a8874550346b52d8b5a06/html5/thumbnails/20.jpg)
All organisms need Carbon to do their life activities
Plants absorb carbon out of the air
Animals get carbon when they eat plants or other animals
Animals release carbon into the air when they breath
![Page 21: Cells: Plant and Animal What is the smallest part of this living thing?](https://reader037.vdocuments.mx/reader037/viewer/2022102603/551a8874550346b52d8b5a06/html5/thumbnails/21.jpg)
All organisms need Carbon to do their life activities
Bacteria and Fungi get carbon from waste and dead organisms and put it into the air
Anything burning also puts carbon back into the air for the plants to use and start the cycle all over again
This cycle is call the Carbon Cycle
