Question

Using the word bank, label the parts of an animal cell. Each word will be used once.

Answer 1

Answer: Using the diagram the labelled parts are identified and matches with the number given below:

1.) Golgi bodies

2.) Cell membrane

3.) Lysosomes

4.) Nucleus

5.) Mitochondria

6.) Vacuole

7.) Endoplasmic reticulum

8.) Ribosome

Explanation:

All living organisms (plants and animals) are made up of cells which are the structural and functional unit. This is because it is the basic organizational unit of life. These cells are made up of structures known as the CELL ORGANELLES. The present or absence of one or more of these organelles creates the difference seen in plant and animal cells. They are briefly describe below:

--> Golgi bodies: they are stack membrane-lined sacs which export materials like enzymes and hormones made from the cell.

--> Cell membrane: this is a flexible membrane made up of protein and lipids that prevents the cell contents from escaping

--> Lysosomes: They are small round sacs that contain digestive enzymes which break down substances.

--> Nucleus: This is the largest and the most important cell organelle. It contains a thread-like network of chromatin granules which is extended to form the chromosomes. The chromosomes contain DNA( which is the molecule that houses the hereditary information of the cell).

--> Mitochondria: this is the site of chemical energy conversions for all cell activities. It is thus often called 'power house'.

--> Vacuole: this acts as a store house for many substances including excretory products.

--> Endoplasmic reticulum: these functions to distribute proteins and other materials throughout the cell.

--> Ribosome: these are sites for protein synthesis. They are found free in the cytoplasm or attached to the endoplasmic reticulum.
