Organisation of cells

Question 1

Epithelial cells in the small intestine are specialised to

Answer 1

absorb food efficiently

Question 2

, in complex multicellular organisms eukaryotic cells become specialised for

Answer 2

specific functions

Question 3

what are cells

Answer 3

the smallest, basic unit of life that is responsible for all of life’s processes.

Question 4

What are tissues

Answer 4

In multicellular organisms, specialised cells of the same type group together to form tissues

A tissue is a group of cells that work together to perform a particular function

Question 5

What are organs

Answer 5

a collection of tissues that structurally form a functional unit specialized to perform a particular function

Question 6

What are organ systems

Answer 6

A group of organs with related functions, working together to perform certain functions within the body.

Question 7

What are organelles

Answer 7

Organelles are membrane-bound compartments that exist within most cell types

Question 8

tissue examples

Answer 8

Epithelial cells group together to form epithelial tissue (the function of which, in the small intestine, is to absorb food)

Muscle cells (another type of specialised cell) group together to form muscle tissue (the function of which is to contract in order to move parts of the body)

Question 9

Different tissues work together to form organs. For example

Answer 9

the heart is made up of many different tissues (including cardiac muscle tissue, blood vessel tissues and connective tissue, as well as many others)
Different organs work together to form organ systems

Question 10
