The document outlines key features and functions of plant and animal cells, highlighting the seven life processes essential for living organisms. It identifies specialized cells, such as sperm, ovum, palisade, root hair, and cilia cells, each adapted for specific functions. Additionally, it describes the four main plant organs—flower, stem, root, and leaf—detailing their roles in reproduction, support, nutrient transport, and photosynthesis.

2. Life Processes and Cells
Lo –to be able to learn all the features
of a plant cell.
- To be able to understand the seven life
processes.

3. The seven life processes!
Moving parts of the body.
Producing offspring's.
Responding and reacting.
Getting food to stay alive.
Getting rid of waste.
Turning food into energy.
Growing to adult size.

4. Both animal and plant cells have -

5. Animal and plant cell!
Nucleus – controls the cell and contains all
the genetic information.
Cell membrane – the lining of the cell and
it controls what goes in and out of the
cell.
Cytoplasm – where all the chemical
reaction take place.

6. Plant cell!
Cell wall – supports the cell.
Vacuole – a large space filled with cell
sap – a weak solution of salts and sugar.
Chloroplasts- contains chlorophyll that
is needed for photosynthesis.

7. Specialised cells
Lo - To identify each specialised cell.
- To be able to learn the explanations

8. All cells are adapted
to do a particular
job. This is called
CELL SPECIALISM.

9. Sperm cell!
• The sperm cell is very small, it has a little tail to
which provides movement so that it can find the
egg to fertilise.
• Its head contains enzymes that are used to break
through the egg membrane so that that two
nuclei can join.
• It also contains chromosomes in the nucleus that
holds genetic information from the father that
will get passed down on to the offspring.

10. Ovum/egg cell!
• It has a large and bulky shape because there is
no need for active movement .
• It has a yolk that provides a large food store
for the young organism when fertilised.
• It also contains chromosomes in the nucleus
that holds genetic information from the
mother that will get passed down on to the
offspring.

11. Palisade cell!
• Large surface area and
found on the top side
of the leaf – ideal for
absorbing CO and light
• They’re packed with
chloroplast which
contain green pigment
chlorophyll- needed
for photosynthesis.
DESIGNED FOR PHOTOSYNTHESIS!

12. Root hair Cell!
• The long root hair cell
increases the surface
area which helps the
absorption of water
and minerals.
• Thin cell wall that
allows minerals to pass
through.
DESIGNED FOR ABSORBING!

13. Cilia cell!
• Cilia cells line all the
air passages in your
lungs.
• They have tiny hairs
that filter the air as it
filters through.
• The hairs sweep
mucus with trapped
dust.
DESIGNED TO STOP LUNG DAMAGE!

14. Cells, tissues, organs and organ system
• A group of similar cells come together to make a
TISSUE.
• A group of different tissues work together to
make an ORGAN.
• A group of organs work together to make an
ORGAN SYSTEM.
(E.G – root hair cells make up a root tissue , which
makes up a root ‘organ’ system, which then
works with other systems to make a plant.)

15. Plant Organs!
LO -to identify key features of a plant
-To learn what each one is for.

16. The Plant!
Four main plant organs allow the life processes to take place.
Flower
Leaf
Stem
Root

17. Plant Organ - Flower
•The flower contains the
organs for reproduction.
•It attracts insects to carry the
pollen between plants to allow
pollination.

18. Plant Organ - Stem
•The stem hold the leaves upright
and facing the light.
•It carries water and minerals to
the leaves, and food around the
plant.
•The stem is important for
nutrition, excretion and growth.

19. Plant Organ – Root
• The roots provide an anchorage for the
plant – so that it doesn’t fall over or blow
away.
• With its root hair it provide a big surface
area to help take in water and minerals –
these are both essential for
photosynthesis.
• The roots are vital for nutrition.

20. Plant Organs – Leaves
• The leaves are important for
photosynthesis, they make all the food for the
plant.
• Leaves contain chloroplast that use light
energy to change CO2 into glucose.
• They have tiny little pores that allow essential
CO in and waste gases out – ( they have no
lungs)
• They leaves are important for nutrition and
excretion.

21. •Every cell in the
plant will respire
and change
glucose into useful
energy. jssssss

22. And that’s the
end of this topic!
Welldone! 
