The discovery of cells began in 17th century by ....... after he observed cork tissue

• Robert Hooke

• Anthoni Van leuweunhoek

• Scopes

• Schleiden and Schwann

• Rudolf Virchow

The structural differences between prokaryotic and eukaryotic cells are as the following, except ....

• The lack true nucleus in prokaryotic cell only. It is only nucleoid

• Prokaryotic cell lacks double membrane organelle

• the differences is only in the presence of nuclear membrane. Both types of cells have the same types of organelles

• Prokaryotic cell are smaller in size than eukaryotic

• Prokaryotics are only found in the eubacteria kingdom

Plasma Membrane functions are ...

• to produce energy

• to give rigidity to cell

• as a gate for ions, molecules, or other compound from inside and outside of the cell

• to use energy

• to synthesize proteins

Transport of molecules from one location to another by using energy is called ....

• passive energy

• passive homeostatis

• active transport

• diffusion

• osmosis

If a 2% salt solution is separated by a semi permeable membrane from a 6% salt solution, ....

• water will flow from 2% to 6% solution

• water will flow from 6% to 2% solution

• there is no change because semi permeable membrane blocks the flow of water and salt molecules

• diffusion occur from 2% to 6% solution

• there is no movement solution

Cell can take large molecules into cytoplasm. Single celled organisms such as Amoeba can capture food by ....

• phagocytosis

• pynocitosis

• ion pump

• fasilitated diffusion

• osmosis

One of the differences between an animal and plant cell is ...

• Animal cell are rigid because they have a cell wall

• plant cells have sentriol that functions in cell division

• plant cells have plastids with diverse shapes and function

• animal cells have a large vacuole that functions to store food backup

• Animal cell have a centriole that function in protein synthesize

A large organelle that contain chromosomes ...

• vacuoles

• nucleus

• cytoplasm

• golgi apparatus

• endoplasmic reticulum

Endoplasmic reticulum is found within the cell. One type has granules on its surface membrane called ....

• ribosome

• lignin

• pectin

• nucleolus
