This document provides information about PowerPoint and chloroplasts. It introduces PowerPoint as a commonly used presentation program that can enhance teaching when used carefully. Next, it defines chloroplasts as structures in plant cells that contain chlorophyll and are involved in photosynthesis. Chloroplasts have an inner and outer membrane, with an internal area called the stroma containing enzymes, and membrane sacs called thylakoids that contain chlorophyll and are arranged in stacks called grana. Chlorophyll absorbs mainly blue and red light, reflecting green light and giving plant parts their green color.

PRESENTATION

4. PowerPoint (© Microsoft Corp.) is a widely used
presentation programme that originated in the world of
business but has now become commonplace in the
world of educational technology.
it is a valuable aid to
presentation providing that its
use has been carefully
considered in terms of
pedagogy

5. Appropriate use of PowerPoint can enhance the teaching
and learning experience for both teachers and students.
A presentation can appeal to a number of different
learning styles and be made more stimulating.
Teachers are encouraged to incorporate more
sophisticated visual and auditory media into presentations

7. INTRODUCTION
•Chloroplast are green,discoid,self-propagating
bodies in the cytoplasm of
plant cells
•They ae green plastids.
•They are concerned with
photosynthesis.
•Chloroplast contains
chlorophyll,carotenoids,DNA
,RNA,Lipids.

9.  All green parts of a plant contain chloroplasts
Within a leaf, chloroplasts are mainly found in the mesophyll
layers of a leaf
They are often absent from the epidermis of a leaf

11.  Chloroplast is a double membraned structure.
 Of which the inner membrane is less permeable
than the outer membrane.
.

12. The space inside the chloroplast is called the
STROMA.
Membranous sacs inside the stroma are the
THYLAKOIDS.
Thylakoids are arranged in stacks called as the
GRANA.

13. Thylakoids contain the chlorophyll pigments.
Stroma contains the enzymes required for the synthesis of
carbohydrates and proteins

15. Chorophyll make
photosynthetic
parts of a plant green
Chlorophyll absorb mainly
blue and red rays of the
visible light .since the green
light is not absorbed at all ,it
is reflected making the leaves
appear green
