Statement that is false :

[ (b) The cell of a whale is larger than the cell of an ant . ]

All the animals are made up of cells that further aggregate to form tissues , organs , organ systems and them an organism.

Both whales and ants are the organisms formed by tiny cells. Cells are of two types :

• Plant cells => exclusively in plants
• Animal cells => exclusively in animals

So , both are made from animal cells. Animal cells are of same size in every organism. May it be an ant or a whale.

Supplementary information :

◼️ What is Cell ? Name the two types of cell.

Cell is a basic structural and functional unit of a life.

The two types of cell are as follows :

• Animal cell
• Plant cell

◼️ Name the parts of Cell.

The parts of cell are as follows :

• Cell membrane
• Cytoplasm
• Nucleus
• Cell organelles

◼️ Differentiate between animal cell and plant cell.

★ Animal Cell :

⭐ Shape = Irregular / not fixed.

⭐ Cell Wall = Absent

⭐ Plastids = Absent

⭐ Vacuoles = Vacuoles are either absent , or are present as small Vacuoles.

★ Plants Cell :

⭐ Shape = Fixed

⭐ Cell Wall = Present

⭐ Plastids = Present

⭐ Vacuoles = One large vacuole is present.
