Function of Ribosomes
site
of
protein
synthesis
contains
RNA
Role of Golgi Apparatus
stores
lipids proteins carbohydrates
makes
vesicles
Role of Centrioles
involved in
cell division
required for
mitosis
and
meosis
Two Processes of Cell Division
Mitosis produces
two
cells
that are
identical
Meiosis produces
four
non
identical
cells
Describe Meosis
A process by which
gametes
are produced
The number of
chromosomes
is
halved
compared to normal cells
Haploid
cells are produced
Four daughter
cells are produced
Describe meosis
A process by which
gametes
are produced (1)
The number of chromosomes is
halved
compared to
normal
cells (1)
Haploid
cells are produced (1)
Four
daughter cells are produced (1)
Explain
how cells divide for growth
By
mitosis
- producing
daughter
cells
Doubling
the
chromosomes
then splitting them
Role of lysosomes
contains
enzymes
- for
digestion
Function of Nucleolus
Makes Ribosomes
Produce RNA
4 Parts of Nucleus
Nucleolus
Nuclear Envelope
Nuclear Pores
Chromatin DNA
Function of
Mitrochondria
Aerobic respiration takes place
Releases energy
Function of Lysosomes
Destroy
pathogens
in cells
Release
digestive enzymes
from the cell
Break down waste materials
Function of
Golgi Apparatus
Receives
proteins
from the
RER
Produces
lysosomes
involved in
lipid synthesis
Function of
Rough Endoplasmic Reticulum
Provides a larger surface area for
protein
and
glycoprotein
synthesis
Provides a pathway for materials to be
transported
Function of Smooth Endoplasmic Reticulum
Synthesises, stores, and transports
lipids
and
carbohydrates
Function of Centrioles
involved in
cell division
required for
mitosis
and
meosis
