Cell Theory and Organelle Notes

It explains why all living things are made of cells and how life is organized.

It describes the process of photosynthesis in plants.

It provides a method for classifying animals.

It explains the structure of DNA.

Composed of one cell

Composed of many cells that may organize into tissues, organs, and organ systems

Composed of only bacteria

Composed of only plant cells

They have a nucleus

They divide by binary fission

They are always unicellular

Their cell walls are made of peptidoglycan

Nucleus, mitochondria, ribosomes, cell wall

Genetic material, cytoplasm, cell membrane, ribosomes

Chloroplasts, cell wall, cytoplasm, nucleus

Cell membrane, mitochondria, ribosomes, vacuole

To control what goes in and out of the cell

To provide energy for the cell

To produce proteins

To store genetic material

It is made of two layers of fats

It contains hydrophilic heads and hydrophobic tails

It is composed only of proteins

It helps maintain homeostasis

Cytoskeleton

Nucleus

Cell membrane

Cytoplasm

To protect the DNA that controls the activities of the cell

To provide energy for the cell

To control what goes in and out of the cell

To hold everything in place

Nucleolus

Ribosome

Golgi Apparatus

Smooth ER

They are made of proteins and rRNA.

They are located on the Rough ER and in the cytoplasm.

They make proteins through translation.

They store calcium ions.
