Cells:Plant and Animal

What is the smallest part of this living thing?

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.

Animal Cell

Animal Cell Nucleus DNAMitochondria

Vacuole

Cytoplasm

Ribosomes

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.

VACUOLES Temporary storage

spaces Store water,

material, & waste Small sized in

Animal Cells Large sized in

Plant Cells

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 Cell

Cell MembraneMitochondria

ER (rough and smooth)RibosomesCytoplasm

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?

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

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
