Plant properties Flashcards
what are all the features of a plant cell
mitochondria
ribosomes
chloroplast
cell membrane
vacuole
smooth endoplasmic reticulum
rough endoplasmic reticulum
Golgi apparatus
nucleus
nucleolus
middle lamella
plasmodesmata
pit
what is the function of the chloroplast
where photosynthesis occurs
Where are amyloplasts found and what is their function
Found -
organelles found in the cytoplasm of plant cells
Function -
used to store starch
what is the tonoplast
the membrane which surrounds the vacuole (vacuolar membrane)
What is the structure and function of the plasmodesmata
structure -
cytoplasmic bridges between adjacent plant cells
function -
allows the transport of molecules between the cells
what is the function of the cell wall
Strength and support
what is the function of the pits
allow water and minerals movement between cells (xylem vessels)
what is the structure and function of the middle lamella
structure -
made of pectin
function -
joins the cell walls of adjacent plant cells together
what are the three main differences between an animal cell and plant cell
animal cells contain centrioles whereas plant cells do not
plant cells contain a vacuole whereas animal cells do not
plant cells contain a cellulose cell wall whereas animal cells do not
what is the structure and function of the sclerenchyma
structure -
plant tissue made up of cells with thickened cell walls
function -
strength and support
what is the structure and function of the xylem
structure -
tissue found in plants
function -
specialised for the transport of water and dissolved minerals up the plant
what is the structure and function of the phloem sieve tubes
structure -
living phloem cells joined to create a long tube
function -
long tubes for effective transport of assimilates
structure and function of the phloem
structure -
a tissue found in plants which is specialised
function -
transports assimilates from their site of production to different parts of the plant where they are needed
what is the structure of the vacuole
structure -
membrane bound structure containing cell sap
what is the function of magnesium ions in the plant
needed for chlorophyll to function so that plants can carry out photosynthesis
ion with the formula Mg2+
what is the function of nitrate ions in the plant
taken up by plants from the soil and is used to make proteins
ion with the formula NO3-
what is the function of calcium ions in the plant
used to form pectins and is very important for the structure of the cell wall in plants
ion with the formula Ca2+
