plant & soil

centre of cell site of genetic transcription

forms protective barrier around nucleus composed of phospholipid bilayer controls movement of substances in & out

largest body within nucleus responsible for production of ribosomal subunits

process & package lipids & hormones

involved in production of proteins ribosomes on surface joined to nuclear membrane to enable rapid movement of information to the ribosomes from nucleus

sorting, modifying and packaging proteins for secretion movement of lipids around cell

cellular respiration - takes nutrients from cell (glucose from photosynthesis) breaks it down and turns it in energy (ATP)

converts light energy from sun into sugars to be used by cell chlorophyll is green pigment for photosynthesis

protein synthesis location in cell determines what kind of protein it makes

composed of a phospholipid bilayer transport materials from on place to another

membrane-bound sac provides structural support & storage for useful materials

organise microtubules provides cell structure pulls chromatids apart during division

structure & protection semi-permeable for osmosis & diffusion across membrane made of lignin - rigidity & support

double layer of lipids & proteins surrounding cell separates cytoplasm from surrounding environment selectively permeable - only lets certain molecules enter & exit active transport

fluid that fill cell holds organelles in suspension gives cell its shape

undifferentiated tissues found at points of growth can differentiate when required allowing plant to grow

what meristems differentiate into don’t change form or function

present at growing tips of stems & roots increases length

consists of cells that mainly divide in one plane causing organ to increase in diameter & growth forms secondary growth

located between permanent tissues present at base of node, internode & leaf base branch formation & growth

transport vessels move water & sugars around plant

tissues on outside of plant

less differentiated comprise much of cell serve many vital roles

move SUGARS via diffusion & active transport stacked end-end creating a tube to carry sugars from source to sink/ sink to site of growth
