cells and leaf structure Flashcards
to learn about cells
what’s the function of the nucleus
the control centre of the cell contains genetic infomation
what`s the function of the cytoplasm
watery jelly like liquid that fills the cell. where chemical reactions take place
cell wall function?
provides support to the cell helping it to keep its shape it is also made of cellulose
chloroplast function?
to absorb the light energy from the sun for photosynthesis. contains a green pigment called chlorophyll
vacuole function
stores cell sap, a solution of sugar and salts
whats a plasmid
a ring of dna
when making a mircoscope what is used to make it easier to see
a stain
what are bacterial cells made of
chitin
from smallest to largest whats the organisation of cells
cell - tissue - organ - organ system - organism
whats the function of the sperm cell
these carry have the genetic information they have tails to swim towards the egg
whats the function of the red blood cell
carry oxygen to cells and carbon dioxide away from them
whats the function of the nerve cell
they carry messages around to the body
muscle cell function
they change length to think us move
whats the function of the root hair cell
has a bigger surface area to take water from the soil
whats the function of the palisade cell
contain chlorophyll to help make the plant food by photosynthesis
whats the function of the ciliated epithelial cell
the hairs called cilia move dirt from the lungs and bring it up from mucus
what does a muscle cell have lots of
mitochoria
does a red blood cell have a nucleas
no
whats the function of the white blood cell
produces antibodies to fight diseases
whats the function of the nervous system
responding to stimuli
whats the function of the reproductive system
producing offspring
whats the function of the excretory system
removes thew waste products from the body
whats the function of the digestive system
breaks down food into nutrients the body can use
job and function of the epidermis
allows light through/physical barrier
job and function of the waxy cuticle
allows light through waterproof/ physical barrier
job and function of the palisade mesophyll
many chloroplasts, carrys out photosynthesis, large surface area
job and function of the spongy mesophyll
afew chloroplasts / large surface area for gas exchange
job and function of the air spaces
allows diffusion of gases through the leaf
stomata/ guard cells
allows gases to diffuse in and out of the cell
whats the function of the mitochordia
carries out respiration to release energy [from glucose]
whats the function of the chromosome
the main genetic material of the cell that controls that controls the cell reactions
whats the function of the cell membrane
controls what substances go in and out of a cell
