What do inclusion bodies do
Act as reservoir of food
How are food stored in inclusion bodies
- Glycogen granules
- Phosphate granules
- Cyanophycean granules
Cell organelles found only in prokaryotes
Inclusion bodies and plasmid
Smallest cell

Components of Endo membrane system
ER, Golgi, lysosomes and vacuoles
Functions of smooth endoplasmic reticulum
- Detoxification of liver
- Form steroidal hormones
- Modify into sarcoplasmic reticulum to store calcium ion
Structure golgi is made up of
Cisternae
Golgi in plants is known as
Dictyosomes
Acrosome of a sperm cell is a modification of
Golgi
Functions of golgi apparatus
- Packaging of secretory molecules
- Glycosylation (Addition of an oligosaccharide chain)
Nature of lysosomes
Acidic
Membrane of eukaryotic vacuole
Tonoplast
Cytoplasmic connection between two cells is known as
Plasmodesmata
Plasmodesmata us held together by

Structure of ribosome us composed of
rRNA and protein
Where is rRNA synthesized
Nucleolus
Eukaryotic ribosome type
80S
40S (smaller sub unit)
60S (larger sub unit)
Eukaryotic cell organelles that are membraneless
Ribosomes and centrosome
(Ribosomes is membraneless even in prokaryotes)
