4. Introduction to cell and functions
CELL: The cell is the basic structural, functional and biological unit of all known living organisms
PLANT CELL: Plant cell is the basic unit of life in organisms of the kingdom plantae. Plant cells are eukaryotic
cells.
PLANT CELL’S FUNCTIONS:
 Parenchyma cells are found in leaves and carry out photocynthesis, cellular respiration along with other
metabolic process.
 Collenchyma cells provide support to growing parts of a plant.
 Sclerenchyma cells are hard cells that are the main supporting cells in the areas of a plants that have ceased
growing.
 Xylem cells transport mostly water and a few nutrients throughout a plant, from the roots to the stem and leaves.
 Phloem cells transport nutrients made during photosynthesis to all parts of plant.

5. Plant cell organells
Plant cell organelles are:
 Cell wall
 Plasma membrane
 Cytoplasm
 Mitochondria
 Plastid
 Endoplasmic reticulum
 Golgi bodies
 Nucleus
 Lysosome
 Vacuole
 Ribosome

6. Cell Wall
Cell wall: Cell wall is an outer layer surrounding certain cells that is
Outside of the cell membrane.
Functions:
 Cell wall provides strength to the cell which helps
the cell against physical damages.
 It gives the cell its shape and allows the organisms to
maintain the certain shape.

7. Cell organelles
Cytoplasm: The jelly-like substance composed of mainly water and found
between
the cell membrane and nucleus.
Functions:
 Organelles float in cytoplasm.
 Substances like salt dissolved in cytoplasm.

8. Cell organelles
Plasma membrane: A bilipid membraneous layer composed of proteins and
carbohydrate.
It is fluid like.
Functions:
 The cell membrane separate the cell from its external environment and is
selectively permeable.
 It protects the cell and provides stability

9. Cell organelles
• Lysosomes: Lysosomes are organelles that contain digestive
enzymes. They also called cell vesicle.
• Functions:
 Digestion of ingested material.
 Autophagy and cell death.

10. Cell organelles
Mitochondria: Mitochondria are round “tube like” organelle that are
surrounded by a double- membrane,
with inner membrane being highly folded. It is called as the
“power house” of the cell.
Functions:
 Converts energy stored food into usable energy(ATP).
 Allows aerobic cellular respiration.

11. Cell organelles
Plastid: Plastid is a major double-membrane organelle found in the plant cell. It
contains pigments and the types of pigments in a plastid determine the cell’s color.
There are three types of plastid.
Functions:
 Chloroplasts are the organelle of photosynthesis.
 Chromoplasts make and store pigments that give petals
and fruit their orange and yellow colors.
 Leucoplasts do not contain pigments and are located in
roots and non-photosynthetic tissue of plants.

12. Cell organelles
Endoplasmic reticulum: Endoplasmic reticulum is a system of folded tube like
Structures attached to the nucleus.
Functions:
 Transports proteins.
 Site of ribosomes.
Golgi body: Golgi body refers to as the “Golgi apparatus” or the
“Golgi complex”. It’s part of the cell’s endomembrane system.
Function:
 Modifies proteins and lipids.
 Make and secrete mucus.

13. Cell organelles
Vacuoles: Vacuoles are kind of large sized vesicles. Vacuoles are present
in the cells of plants, animals, protists, fungi and bacteria. Vacuoles in plant
Cells are larger than animal cells.
Functions:
 Vacuoles store food ,water, waste, proteins, carbs.
 Helps maintain homeostasis.
Ribosome: Ribosome is a complex molecular machine, found within all living cells that is composed of RNA and protein.
Functions:
 Protein builder of the cell
 DNA synthesis.
 Intracellular digestion.

14. Cell organelles
Nucleus: Nucleus is the largest organelle in the cell. It is also referred
to as the control center of a cell. Nucleus contains all the genetic material
of an organisms like chromosomes, DNA, genes etc.
Functions:
 Exchange of hereditary molecules (DNA and RNA
between the nucleus and the rest of the cell.
 Storage of proteins and RNA in the nucleus.
 Nucleus is a site for transcription in which messenger
RNA are produced for protein synthesis.
