Question

name the different cell organelles and the functions of these organelles

Answer 1

mitochondria
produces energy through cellular respiration

rough endoplasmic reticulum
transport and storage

ribosomes
create proteinssmooth endoplasmic reticulum
creates lipids or fat

chloroplast
creates glucose

golgi apparatus
synthesis, packages and releases concentrate proteins or lipids

golgi body
protein or lipid enters the cytoplasm

cytoplasm
where all chemicals take place

glycoprotein
short sugar chains attached to proteins

glyco lipids
lipids attached to proteins

cisternae
flattened stacked membrane folds

liposome
small membrane bounded transport vesicles

peroxisome
microbodies found in animal cells

glyoxysome
microbodies found in plant cells

centrioles
for cellular division and cellular reproduction

cytoskeleton
supports structure and helps move synthesized proteins

lysosomes
contain hydrolytic enzymes for digestion

cilia
hair like structures

flagellum
tail

contractile vacuole
pump water out of cell

red blood cells
carries oxygen, glucose

vesicle
moves protein, lipid and carbohydrate

nuclear envelope
surrounds the nucleus

vacuole
contains food or water

cell membrane
separates cell contents from the environment

microtubules
provide internal support

nucleus
information center of the cell

nucleolus
site of ribosome synthesis

chromatin
threadlike mass of DNA

Answer 2

Answer:

Functions performed by the Cell Organelles:

1. Endoplasmic Reticulum -

  (a) Smooth Endoplasmic Reticulum

• Synthesis of Lipids & Steroids.
• Detoxification of Drugs.
• Associated with muscle contraction by release & uptake of $ca^{2+}$ ions.

  (b) Rough Endoplasmic Reticulum

• It gives rise to SER (Smooth Endoplasmic Reticulum).
• Site for Protein Synthesis
• Provides precursors of enzymes for the formation of Lysosomes in Golgi Complex.

2. Golgi Complex -

• The important function of Golgi apparatus is to package the material and prepare for secretions.

• The  packaged material is delivered either to the intracellular targets i.e. within the cell or secreted extra cellular  targets i.e., outside the cell.
• The material to be secreted moves from ER to the Golgi apparatus in the  form of vesicles. These vesicles are then fuse with the cis face and move towards the maturing face of  the golgi apparatus.

• Golgi apparatus is closely associated with ER in structural as well as  functional aspects.
• A number of proteins synthesised by ribosomes on the ER are transferred to Golgi apparatus. These proteins  are then modified in the cisternae of Golgi apparatus before they are released from its trans face.
• Golgi apparatus is the important site of formation of glycoproteins and glycolipids.

3. Nucleus -

• Highly specialized organelle - serves as the information processing & administrative center of the cell.

        2 Major functions:

• Stores the cell's hereditary material(DNA)
• coordinates the cell's activities Growth, Metabolism, Protein synthesis, & Reproduction (cell division).

4. Chloroplast -

• Photosynthesis
• Storage of starch

5. Vacuoles -

• Storage
• Ingestion
• Digestion
• Excretion

6. Mitochondria -​

• Main site for Aerobic Respiration.
• Power House of the cell.
• Helps to perform various energy requiring processes.
