Plastids Flashcards
three types of plastids
leucoplasts
chromoplasts
chloroplasts
which plastid is used to store nutrients and is colourless
leucoplast
three types of leucoplast
amyloplast
elaioplast
aleuroplast
amyloplast contains
starch
examples of amyloplast
potato tuber
elaioplast store
oils and fats
aleuroplast store
protein
colour of chromoplasts
yellow/orange/red
chromoplasts have their colour due to which pigment
carotenoid pigments like carotene, xanthophyll
colour of chloroplasts
green
which pigments do chloroplasts have
photosynthetic pigments like chlorophyll and carotenoids
which plastid takes part in synthesis of food
chloroplast
where are chloroplasts found
mesophyll cells of leaves
thickness and length of chloroplasts
thickness: 2 to 4 micrometers
length: 5 to 10 micrometers
number of chloroplasts in chlamydomonas
1 per cell
number of chloroplasts in mesophyll
20 to 40 per cell
two membranes of chloroplasts
inner membrane
outer membrane
which membrane of chloroplasts is less permeable
inner
which membrane of chloroplasts has proteins including carrier proteins
inner membrane
matrix of chloroplasts is called
stroma
stroma of chloroplasts contains a large number of organised flattened membranous sacs called
thylakoids
thylakoids are arranged in piles called
granum
thylakoids of chloroplasts are connected by
stroma lamella
matrix of thylakoids is called
lumen
