Organisms

Question 1

What are the two types of organisms

Answer 1

Unicellular
Multicellular

Question 2

What are unicellular organisms and their function

Answer 2

Are made of one cell that live alone or in colonies
Are microscopic and perform all life processes

Question 3

What are multicellular organisms and their function

Answer 3

Are made on many cells and have specialization of cells which form tissues

There are advantages and disadvantages to these organisms:
1.Division on labour - cell specialization allows specific functions to be carried out efficiently.
2.size - able to grow larger due to transport systems.
3. Interdependence of cells - if one cell dies the entire organism does not die.

Question 4

What is cell specialization and when does it occur

Answer 4

It’s when a cell is designed to perform a specific function
It occurs when cells begin to form organs and organ systems

Question 5

What are tissues? Provide some examples

Answer 5

A result of cell specialization

Tissues are groups of cells performing the same functions

Examples would be red blood cells or dermal tissue

Question 6

What are organs? Provide an example

Answer 6

A result of cell specialization

Organs are groups of tissues performing the same function

Example would be our heart

Question 7

What are organ systems? Provide an example

Answer 7

A result of cell specialization

They are organs contributing to the same function

Example would be the circulatory system

Question 8

What type of organism is a plant

Answer 8

They are multicellular organisms

They consist of organ systems and specialized cells
