THE
ORGANELLES IN
A PLANT CELL
Quick facts about the plant cell
*THE FIRST THING THAT IS WONDERFUL ABOUT PLANT CELLS IS THAT THEY ARE THE ONLY PRODUCERS OF
FOOD BY SELF ON EARTH.
* THEY HAVE AMAZING FEATURES LIKE CHLOROPLASTS, RIGID CELL WALL AND VACUOLE. THEIR FEATURES
RESEMBLE THOSE OF ANIMAL CELLS.
*PLANTS RETAIN A DEFINITE SHAPE DUE TO THE RIGID CELL WALL. THEY TAKE IN LOTS OF WATER BUT THE
RIGID CELL WALL HELPS THEM RETAIN THEIR SHAPE
*WITHOUT SUN, PLANTS ARE NOT ABLE TO PRODUCE FOOD. WITH ENERGY DERIVED FROM SUN, PLANT CELL
CONVERTS CARBON- DI- OXIDE AND WATER INTO CARBOHYDRATES AND SUGAR AND PREPARE FOOD.
*ONE SIXTH OF THE ENERGY DERIVED FROM SUN IS USED BY PLANTS AND REMAINING ENERGY GOES TO
HUMAN BEINGS AND ANIMALS IN THE FORM OF SUGAR AND CARBOHYDRATES AND FORMS THEIR FOOD.
*WITHOUT PLANT CELLS AND THEIR FEATURES, FOOD FOR PLANTS IS IMPOSSIBLE
*MANY PLANTS ARE VERY SMALL BUT THEY HAVE MINI ORGANS WHICH ARE USED FOR PRODUCING FOOD.
WITHOUT PLANT KINGDOM, MAN MIGHT HAVE SUFFERED A HEAVY LOSS IN FOOD PRODUCTION.
The Plant Cell
THE PLANT CELL IS CONSIDERED
A EUKARYOTIC CELL. TODAY YOU
WILL BE LEARNING THE MANY
ORGANELLES THAT ARE IN A
PLANT CELL
The Vacuole
•
The main
function of the
vacuole is to
store water
Chloroplasts
• Function: traps energy
from the sun to produce
food for the plant cell
- Appearance: green in
color because of
chlorophyl, which is a
green pigments
Cell Wall
• - Function: provides
support and protection to
the cell membrane
- Found outside the cell
membrane in plant cells
Cell
Membrane
•thin, flexible barrier
around a cell;
regulates what
enters and leaves
the cell
The Nucleus
•
Nickname: "The Control
Center"
- Function: holds the DNA
- Parts:
- Nucleolus: dark spot in the
middle fo the nucleus that
helps make ribosomes
Ribosomes
• - Function: makes
proteins
- Found in all cells,
prokaryotic and
eukaryotic
Endoplasmic
Reticulum
• - Nickname: "Roads, "ER"
- Function: the internal delivery system of the
cell
- Parts:
- Rough ER
- Function: helps make proteins, that's why it
has ribosomes
- Appearance: rough appearance because it
has ribosomes
- Smooth ER
- No ribosomes
- Function: makes fats or lipids
Golgi
Complex
Nickname: "The Shippers"
- Function: packages,
modifies, and transports
materials to different
locations inside/outside of
the cell
- Appearance: stack of
pancakes
• -
Lysosomes
• - Nickname: "Clean-up Crews"
- Function: to break down
food into particles the rest of
the cell can use and to
destroy old cells
- Appearance: circular, but
bigger than ribosomes
Mitochondria
• Nickname: "The Powerhouse"
- Function: energy formation >
breaks down food to make
ATP
- ATP = the major fuel for all
cell activities that require
energy
Cytoplasm
•a jellylike fluid
inside the cell in
which the
organelles are
suspended
