What is biology

Bio means

Logos means

The person who studies biology

Branches of Biology

Sub branches of Biology

Deals with the identification, classification and nomenclature of living organism

Deals with the structure of organism and their body parts Deals with human body

Deals with the normal function of living organism and their body parts

Deals with with the structure, composition and function cell

Deals with the transmission of heridetary characteristics from one generation to next generation

Study of various sequencial and development changes of the organism from the time of its origin

Study of interaction of organism with each other and with their environment

Primary building block of life

Smallest cell

Largest cell

Example of cells

Latin word of Cell

Cell also called as _____

Rooms in cell is called ______

Anton Van Leeuwenhoek ()

Who observe the cell

Who name "Very Little Animalcules" of cell

Robert Brown ()

who is the Scottish bonatist

Describe the Nucleus present in the cell and orchids

Who discover the cell

German Botanist

Mattias Schleiden ()

Who discover that all parts of plant is composed of cells

Theodor Schwan ()

Who prove that basic unit of animal tissue is cell

Rodulf Virchow ()

Prove that all cell come from free existing cell

3 cell theory

Are the different structure inside a cell that each have different jobs or function

Known as "security guard"

As it has small holes that let some molecules in but keep out any harmful molecules

Helps keep everything inside the cell protected

The fluid that fill the cell

Known as "control center"

Controls growth and reproductions

Can be found inside the nucleus

Convert sun energy of the sun into sugars

Also known as "Power house" Perform cellular respiration

Turns combination of molecules into new, more complex molecules and then sends them out of the cell or stores them

Important in the creation and storage of lipids

Works with ribosomes attached to it to help with the synthesis and packing of proteins

Storage bubble that stores food nutrients the cell needs to survive

Also known as "protein builders"

Small organelles that build long chains of amino acids for the cell

Organelle that digest nutrients and helps break down toxic materials

Helps digest and break down food in the cell with the help of enzymes that are stored here

Helps provide structure to the cell and also helps with cell devision

Helps the cell divide during mitosis and meiosis

Have larger Vacuole

Only have cell membrane

Have cell walls

Process that accurs after cell division,

3 types of cell modification

Accurs at the top of the cell

Accurs at the side of the cell

Accurs at the bottom of the cell

Types of Apical modification

Also known as "false feet"

Short hair like structure

Whip like modification

Finger like projections

Smaller protections

Compound secreted by the cell on its apical surface Plants cell that distinguishes them from animal cell

Types of Lateral Modification

Also known as communicating junction

Allows direct flow of molecules between cells

Held two adjacent cell tightly

It anchors junction on the lateral surface of the cell

Types of Basal modification

Rivit like links between cytoskeleton

Prokaryotic came from Greek word Pro - Karyo -

Lack of true nucleus and other membrane enclosed organelles

Eukaryotic came from Greek word Eu- Karyo -

Have true nucleus and internal membranes that compartmentalize cellular function

Group of cells that have the same structure and function

4 basic types of Tissue

Found throughout the body as covering of both internal and external surface

classified based on the layers of cells

One layer of cell

More than one layer of cell

Gives wrong impression that there is more than 1 layer of cell

Connecting tissues to one another Supporting and moving Storing Cushioning and insulating Transporting Protecting

4 types of connective tissue

Transfort oxygen, carbon dioxide, hormones, nutrients waste products and other substances

Loose packing and supporting for the structures with which it is associated

Types of cartilage

Support and flexibility, forms smooth surface of joint

Flexible and capable of withstanding considerable pressure.

Provide regidity but more flexible than hyline cartilage because elastic fibers return to their normal shape

Provide great strength, support and protect internal organs

Types of muscle tissue

Composed of long cells called muscle fibers that allow the body to move voluntarily or involuntary

Voluntary movements of the body
