which organisms/kingdoms have eukaryotic cells?

animalia, Plantae, Fungi, and Protista

state the function of the nucleus

contains DNA while controlling what a cell does

state the function of a cytoplasm

jelly like substance where chemical reaction happens

what is cell membrane

holds the cell together and controls what goes in and out

what is mitrochondria

tiny structures in a cell where most of the reaction for aerobic respiration take place.

cell wall?

coating made of cellulose - gives support to cell

what is a vacuole

filled with sap a weak solution of sugar and salts

What is chloroplast ?

contains chlorophyll used for photosynthesis

state three similarities between and animal and plant cell

cell membrane, cytoplasm, and a nucleus

state three differences between animals and plant cells

plant cells have a rigid cell wall while animals cells do not; plant cells contain chloroplasts for photosynthesis, which animal cells lack; and plant cells typically have a large central vacuole for storage and support, whereas animal cells have smaller vacuoles. 

what substance makes up plants cell wall

Aerobic endurance

the ability of the heart lungs and blood vessels to supply oxygen and nutrients to working muscles during sustained physical activity

muscular endurance

the ability of voluntary muscles to continue to contrast at a light/ moderate intensity to allow repetitive movements eg.football

muscular strength

maximum force that can be generated by a muscle or a muscle group in a single maximum effort eg weight lifting

speed

timetaken to cover a set distance or move body parts in an event or game eg sprinting swimming

flexibility

the range of motion possible at a joint to allow improvements in a technique. its important in order to reduce risks of muscles strains and injuries eg gymnastics

Body composition

the ratio of fat mass to fat free mass in the body. Better suited to certain sports or positions than other

power

combination of strength and speed eg golf. This is important in explosive events

Agility

the ability to change direction quicklyto allow performers to out manoeuvre opponents eg basketball badminton

reaction time

the time between the presentation of a stimulus and the start of a response eg table tenis

balance

the ability of the perfomer to retain their centre of mass over their base of support without falling eg surfing

coordination

the ability to move two or more body parts at the same time smoothly
