Bacteria

17
Q

What is multicellular

A

Organisms made up of many cells

18
Q

What are specialised cells and an example

A

cells that are adapted to carry out a particular function e.g. sperm cell has a tail to allow it to swim

19
Q

What is tissue and example

A

Group of similar cells working together to perform a shared function e.g. muscle

20
Q

What is Organ and example

A

Made up of several types of tissue and carries out a specific function e.g. heart

21
Q

What is organ system and example

A

Group of organs that operate together to carry out a particular function e.g. circulatory system

22
Q

Plant organ system

What is the Shoot System & Root System

A

Shoot system
Above ground parts of a plant (e.g. stem leaves, flowers) responsible for photosynthesis and reproduction

Root System
Below ground parts of a plant (e.g. roots) responsible for anchorage and absorption of water and nutrients (may also be involved in storage of energy)

23
Q

Why do you start viewing with a low power objective lens first

A

Allow you to locate the specimen
Prevent damage to lens when trying to focus for the first time

24
Q

How is magnification calculated

A

magnification = eye piece magnification x objective magnification

25
Q

Purpose of the coverslip method

A

to hold the specimen in place and protect it from contamination from the environment

26
Q

What are two commonly used stains

A

Iodine and Methylene Blue

27
Q

How can you tell it is an onion cell

A

no chloroplasts (it is underground, no light meaning no need for chloroplasts)
