Cells and microscope

movement needs energy

bird eating worm

growth

a plant growing needs water

Sensitivity responses to environment

pupils srink when going form dark to light

waste removal

kidneys filter waste products which are stored in blatter than released

unicellular

living things consist one cell that dose all necessary life functions

multicellular

a living thing mad of more than one cell

resolving power

helps see 2 tiny things as sperate things instead of big blob

magnification power

a measurement of how much larger an object appears when viewed in microscope

cellular resperation

the process Cells use to turn food into oxygen into usable energy whatever,carbon dioxide

photosynthesise

use sunlight water and carbon dioxide to create sugar for energy that releases oxygen into air

eyepiece

used for viewing with a lens that magnifys

objective lenses

have different magnification powers to magnify object

stage

the specimen is placed for viewing

light source

gives light that is needed to view slide

arm

servvies as primary handle

course focus knob

brings image into focus at low and medium power

fine focus knob

brings into focus at high power

base

provides stability and support

low power

4 ×10 =40

medium power

10×10=100

high power

10×40=400

electron micrgraph

tiny specimen taken using an electron microscope

3 part cell theory

1. all living things are made of one or more cells

2. cells are basic units of life

3. all cells come from prexisitng cells

diffrence between eukaryotic and prokaryotic cells

prokayotic does not have organelles eukaryotic dose have organelles

cytoplasm

fills a cell and hold its internal parts in place

nucleus

stores DNA and controls cell activity and passes genetic info

endplasmic reticulum ER

motifyes protiens and fats and has tubes that send materials to golgi body

ribosomes

produce protine

golgi body

packages materials for transport

vesicals

transports stores and digest substances

vacuoles

stores water nutriens protiens and minerals

lyosomes

digestive system and garbage disposal of cells

cell Membrane

lets good nutriens and oxygen in while moving waste and toxins out

mitochandria

take the food you eat and turn it into a form of energy that your cells can actually use.

chloroplast

which is the process of turning sunlight, water, and carbon dioxide into sugar (food) and oxygen.

cell Wall

protects plant cells gives them shape

3 differences between pant and animal cells

1. plant cells have a cell Wall and chloroplast for making food

2. animal cells do not have chloroplast must consume food from energy (plant and animals)

3. plant cells have large central vacuoles

Bacteria and viruses

1 structural same

both contain DNA and microscopic germs

1 functional similarly

both can reproduce

1 diffidence

bacteria living viruse not living
