MRS GREN
movement, reproduction, sensitivity, growth, respiration, excretion, nutrition
what is movement in mrs gren
being able to change position, going towards or away from something (a stimulus)
what is reproduction in mrs gren
being able to produce offspring (babies)
what is sensitivity in mrs gren
being able to respond to things in your environment eg plants moving to face the sunshine
what is growth in mrs gren
increasing in size
what is respiration in mrs gren
a chemical reaction that occurs inside all cells which releases energy from food
what is excretion in mrs gren
removal of waste products from your body
what is nutrition in mrs gren
taking in nutrients to aid growth eg plants to absorb nutrients like magnesium from the soil
cell membrane
controls the substance entering + exiting the cell
cytoplasm
where chemical reactions occur
ribosomes
make protiens
nucleus
controls the cell
mitochondria
produce energy
vacuole
contains the cell sap + keeps the cell shape
chloroplasts
contain chlorophyll for photosynthesis
cell wall
provides structure

best practices for biological drawing
use a sharp pencil, single clean lines, use a ruler for label lines, don’t cross over label lines, and write down the magnification
all cells come from…….
previous cells
what are specialised cells
cells that do a specific job within the body
what is differentiation
when cells become specialised to perform a specific function
cells - __________ - organs
tissues
cells are the basic units of……
life
groups of cells to perform a function are……..
tissues
organs join together which perform a……
function
specialised cell - ______ - organ - __________ - organism
tissue, system
muscle cell - _______ - heart - ___________
muscle tissue, circulatory system
liver
cleans the blood and sends liquid waste to the bladder
stomach
digests or breaks down food into smaller pieces and holds food for about 2 hours
skeleton
gives the body its shape and protects organs
nose
helps us smell and uses mucus to clean and/or warm air
pancreas
makes pancreatic juice and insulin to regulate blood sugar
gallbladder
stores a greenish-yellow liquid called bile and is shaped like a pear
tongue
helps us taste bitter/sweet/sour/salty
eyes
helps us see and uses tears to clean
heart
pumps blood throughout the body
ears
helps us hear
lungs
takes carbon dioxide out of the blood and puts oxygen in
skin
protects body from getting hurt and covers the whole body
brain
sends messages to the body and helps vital organs do their job eg. heart, lungs
bladder
storehouse for liquid waste
muscles
helps hold organs in place and help organs do their job
large intestine
5 foot long and pushes solid waste out of the body
small intestine
20 foot long and digests food as it pushes the food to the large intestine
kidney
cleans out poisons in the blood and takes vitamins out of the blood
spleen
destroys worn our red blood cells and stores red blood cells
what organs are in the reproductive system
ovaries, uterus, oviduct
what organs are in the digestive system
stomach, intestines, pancreas
what organs are in the circulatory system
heart, arteries, veins
what organs are in the excretory system
kidneys, liver, skin
what organs are in the sensory system
ears, eyes, nerves
what organs are in the nervous system
brain, spinal cord nerves
what organs are in the respiratory system
trachea, lungs, diaphragm
what are the different components of a microscope (top to bottom)
eyepiece lens, varying objective lenses, side clips, stage, coarse focus, fine focus, light
