...
They harvest the energy of sunlight by converting
light energy to chemical energy, which they store in bonds formed
when they synthesize carbohydrates from carbon dioxide and water
...
As a substitute for motility, they have evolved
the ability to grow toward essential resources, such as light, water,
and mineral nutrients, throughout their life span

Terrestrail plants lose water continuously by
evaporation and have evolved mechanism for
avoiding desiccation

The Plant Cell
Rough endoplasmic
reticulum :
is primarily concerned with the
synthesis, folding and modification
of proteins, especially those that
need to be delivered to different
organelles within the cell, or secreto
ed from the cell
...


Nucleus :

that contains the genetic information primarily
responsible for regulating the metabolism, growth,
and differentiation of cell
...
That includes portions of one or more
chromosomes where ribosomal RNA gene are
clustered to form a structure called nucleolar
organizer
...


Vacuole :
Golgi body :

is responsible for
transporting, modifying,
and packaging proteins
and lipids into vesicles
for delivery to targeted
destinations
...
Enclosed by this are the cell’s constituents,
often large, water-soluble, highly charged molecules such as proteins,
nucleic acids, carbohydrates, and substances involved in cellular metabolism
...


Middle lamella :

cells are glued to each other by a pectic
polysaccharide rich material known as middle
lamella
...


Primary cell wall :

is the cellulose-containing layer laid down by cells that
are dividing and growing
...
