Answer 2

1. Building blocks of life

• Cells
• Cells are known as building blocks of life because they are fundamental structural and functional units of our life.

2. A cell bound by a nuclear membrane

• Eukaryotic cells
• In eukaryotes, regardless, the DNA takes the structure of compact chromosomes which are separated from the rest of the cell by a nuclear membrane.

3. An additional wall outside the cell membrane

• Cell wall
• The cell wall exists only in plants and in a few fungi, bacteria and algae. It is an additional wall outside the cell membrane which is strong, flexible and sometimes rigid in its composition.

4. Responsible for the hereditary characteristics in living organism.

• DNA, or deoxyribonucleic acid
• DNA (deoxyribonucleic acid) is the hereditary material in humans and almost all different organisms.

5. Longest cell in our body.

• Neurons
• The longest cells in the human body are neurons and these are cells within the nervous system which carry messages throughout the body.

6. Helps Amoeba to move from one place to another

• Pseudopodium
• Amoeba move by the expansion of the pseudopodium which is an attachment of the pseudopodial membrane to the substratum, and separation of the membrane from the substratum.
