The document describes several key organelles in cells, including the endoplasmic reticulum which transports materials and provides structure, mitochondria which generate energy, ribosomes which synthesize proteins, vacuoles which store materials, the Golgi complex which collects cell secretions, and chloroplasts which facilitate photosynthesis in plant cells through chlorophyll.

1. CELL ORGANALLES

2. ENDOPLASMIC RETICULUM
• It is the passage in cell.
• Helps in conduction of food
materials in to the cell.
• Also known as cytoskeleton
because it provides shape and
firmness to cell.

3. MITOCHONDRIA
• Power house of the cell.
• Helps in storage and energy
production.
• Seen in liver, brain, muscles.

4. RIBOSOMES
• It is the centre for Protein
synthesis.
• Seen either attached with
endoplasmic reticulum or free in
cytoplasm.

5. VACUOLES
• Helps to store water, salt,
excretory materials.
• Contains characteristic
membrane called tonoplast.

6. GOLGI COMPLEX
• It collects cell secreations like
enzymes, hormones, mucous
etc.
• It is seen in glandular cells.

7. CHLOROPLAST
• It is the special part of plant cell.
• It contain chlorophyll pigments
which helps in photosynthesis.
