Power point for biology

1. ANIMAL
CELL

2. An animal cell is a type of
eukaryotic cell, enclosed by a
plasma membrane.

3. Cell membrane
• A selectively permeable membrane
that enclose the cell content.

4. •A cell membrane allows only
specific materials to move in and
out of the cell.

5. The different parts of the Cell is what we
called ORGANELLES

7. Cytoplasm
•It is a jelly like
substance.
•Its provides a surface
for all the organelles in
the animal cell.

8. Nucleus
•The control
center of the cell
and the one that
decide and
control most of
the function
going on in the
cell.

9. Mitochondria
•These are
the sites for
the Cellular
respiration
the cells. The
powerhouse
of the cell.

10. •Mitochondria are the powerhouse of
the cell because they release energy
rich compound, the ATP
•Glucose and oxygen react
•ATP is needed for the functioning,
growth and maintenance of the
body.

11. Endoplasmic reticulum
•Folded membrane that forms a system of
canals that transport and exchanging
materials in the cell.

12. 2 Types of Endoplasmic reticulum
•1. Smooth Endoplasmic reticulum
•2. Rough Endoplasmic reticulum

13. 1.Smooth endoplasmic
reticulum
• The main function is to make
cellular products like
hormones and lipids.

14. • The production of lipids (fats), building blocks for
carbohydrate metabolism and the detoxification of
drugs and poison.

15. 2.Rough
endoplasmic
reticulum
•It has
ribosomes that
produce and to
make proteins.

16. Golgi Apparatus
•Packages
and move
materials
out of the
cell.

17. Lysosome
•Breaks down
food and
digests
wastes and
old cell parts
‘garbage
disposal’.

18. Chromatin
• Long strands of
DNA scattered
through the cell’s
nucleus.
• A substance
located in the
nucleus, consisting
of RNA and DNA
and other proteins.

19. Centrioles
•Only in animal
cells and are
important
during cell
division.

20. • They help determine the
locations of the nucleus and
other organelles within the cell.

21. Nucleolus
•A darker,
condensed
part of the
nucleus that
makes the
ribosomes.

22. Ribosomes
•Manufacture
the proteins
in the cell
(protein
synthesis).

23. Cytoskeleton
•It is a
structure that
helps cells
maintain their
shape and
internal
organization.

27. Answer
Cell organelle Functions
1. Centrioles Only in animal cell and are important during cell division.
2. Chromatin Long strands of DNA scattered through the cell’s nucleus.
3. Endoplasmic reticulum Folded membrane that forms a system of canals that transport materials in the cell.
4. Golgi apparatus Package and moves materials out of the cell.
5. Lysosome Breaks down food and digests wastes and all cell parts.
6. Mitochondrion Where energy is produced in the cell.
7. Cytoskeleton A structure that helps cells maintain their shape and internal organization.
8. Nucleolus A darker, condensed part of the nucleus that makes the ribosomes.
9. Nucleus The ‘control centre’ of the cell that contains the DNA and the nucleolus.
10. Plasma/cell membrane A selectively permeable membrane that encloses the cell contents.
11. Ribosomes Manufacture the proteins in the cell (protein synthesis).
