CBSE Questions for Class 8 Biology Cell Structure And Functions Quiz 6 - MCQExams.com

A pseudopod or pseudopodium is a temporary arm-like projection of a cell membrane in amoebas that is developed in the direction of movement.

The formation of cytoplasmic projections, or pseudopodia, on the forward edge of the cell, pulling the cell along, is characteristic of the microscopic unicellular protozoans known as amoebas.

It facilitates movement and helps in capturing food.

So, the correct option is c.

• All of the living organisms are made up of cells. Cells can give rise to new cells by cell division. Each cell has a particular life span. Cells possess machinery, enzymes to form living protoplasm from non-living materials. 
• For example, plant cells take up CO$$_2$$ and O$$_2$$ from the environment and make food in the presence of sunlight. Animal cells break down or oxidize glucose and form ATP. 
• Such ATPs are used as energy currency in cell and various processes of cell formation organelle are carried out. Thus, the correct answer is option D.

• Cell shape is determined by the function of the cell. Three general factors determine cell shape: the state of the cytoskeleton, the amount of water that is pumped into a cell, and the state of the cell wall.
• Thus, the functioning of the cell determines the cell shape. The statement is True.

• Cells are the building blocks by which living things are made. Though all cells nearly have the same basic structure, the plant cell and the animal cell vary in some characteristic features.
• Plastids and cell walls are seen only in plant cells.
• The cell membrane is seen in both plant and animal cells.

The 3 major parts of the cell are :

1. Plasma Membrane - The outer covering of the cell that encloses the cytoplasm.
2. Cytoplasm - The jelly-like matrix within the cell that contains the various organelles.
3. Nucleus - Round and usually centrally placed structure that controls the various activities of the cell.

So, the correct answer is option A.

• Genes are present in chromosomes inside the nucleus and not in the plasma membrane.
• The cell membrane forms the border of the cytoplasm.
• The cell membrane regulates the passage of materials.
• The cell membrane is found in both plant and animal cells.
