Cell wall, Vacuoles and chloroplast Flashcards
Which organelle is absent from plant cells?
Centriole
The cell wall is outside…
the cell surface membrane.
The cell wall is rigid thanks to…
the fibres and cellulose.
The cell wall gives a define…
shape and prevents the cell from bursting.
The cell wall may be reinforced with…
extra cellulose or lignin.
The cell wall is freely…
permeable.
Plasmodesmata are fine…
strands of cytoplasm that pass through the walls of neighbouring cells.
Protoplast is…
everything inside the cell membrane, including it.
Plasmodesmata are used for…
quicker and more efficient communication between cells.
Plant vacuoles are…
large, permanent and central.
Chloroplast is…
relatively large organelle.
Granum is a small…
the structure inside the chloroplast responsible for light absorption.
Granum consists of…
stacks of membrane-bound sacs called thylakoids.
Granum contains…
70s ribosomes and circular DNA.
Chloroplast has two…
membranes. The inner membrane is folded into granum.
