Cell Introduction

• In this power point we will go over the various
  cell parts and their functions.
• The picture to the right is of a composite cell.

3
Cell Membrane

• The cell membrane is a very thin bilayer that
  surrounds the cell. It is made of lipids,
  proteins and some carbohydrates. The membrane is
  selectively permeable, which means that it
  controls what comes in and out of the cell.
  Another function of the cell membrane is signal
  transduction, which means that makes the cell
  aware of its surrounding.

4
Cytoplasm

• The cytoplasm is the jelly of the cell. It is
  made of cytosol. It also has protein tubules and
  rods that make up the cytoskeleton.

5
Mitochondria

• It is a long, fluid-filled sac. It has an outer
  and inner layer. The inner layer has cristae,
  the enzymes on cristae control some chemical
  reactions that make ATP. They are also involved
  in aerobic respiration.

6
Endoplasmic Reticulum

• Its made of flattened sacs, long canals, and
  fluid filled sacs called vesicles.
• Rough E.R. has ribosomes on it and is part of
  protien synthesis.
• Smooth E.R. doesnt have ribosomes and is part of
  the lipid synthesis.

7
Ribosomes

• They are made in the Nucleolus.

8
Golgi Apparatus

• It is made of flattened sacs, it refines,
  packages, and delivers protiens.

9
Lysosomes

• They are the garbage disposals of the cell. They
  break down old cell parts and digest bacteria.

10
Peroxisomes

• They have enzymes that speed up synthesis of bile
  acids, detoxification of hydrogen peroxides, and
  break down certain lipids and rare bio chemicals.
  

11
Microfilaments Microtubules

• Microfilaments are tiny rods and microtubules are
  long, bigger tubes. They provide cell movement.

12
Centrosome

• It consists of 2 hollow cylinders called
  centrioles, and they distribute chromosomes
  during mitosis.

13
Vacuoles

• A tiny bubble like vesicle with a liquid or solid
  material. And appears in the cytoplasm. Its main
  function is to transport things for the cell.

14
Nuclear Membrane

• A bilayer structure that surrounds the nucleus,
  it has nuclear pores that allow certain molecules
  to leave the nucleus.

15
Nucleus

• It contains Chromatin which is loosely coiled
  DNA. It directs cell activity. Inside is the
  Nucleolus.

16
Nucleolus

• It makes ribosomes.

17
Plant Cell

• The plant cell is Eukaryotic. In addition to
  have the same parts as the animal cell, the plant
  cell also contains chloroplasts which contain
  chlorophyll. (the green stuff that makes the
  plant green.)
• They have enzymes that speed up synthesis of bile
  acids, detoxification of hydrogen peroxides, and
  break down certain lipids and rare bio chemicals.
