What are the differences between eukaryotic and prokaryotic cells?

  1. Eukaryotic cells are much larger than prokaryotic cells.
  2. Eukaryotic cells contain membrane-bound organelles, while prokaryotic cells do not. 
  3. Eukaryotic cells keep their DNA in the form of chromosomes within a nucleus, whilst prokaryotic cells have their DNA loose in the cell.

For animal, plant, and bacterial cells, state whether they are either eukaryotic or prokaryotic.

Animal and plant cells are eukaryotic.


Bacterial cells are prokaryotic.

Name 5 sub-cellular structures (organelles) that are found in both animal and plant cells. 

Answer in your head, out loud, or on paper, then tap the card to flip.

What is the cell membrane and what is its role? 

The cell membrane is a protective barrier around the outside of the cell.


It controls which substances can pass in and out of the cell.

What is the cytoplasm and what is its role? 

The cytoplasm is a jelly-like liquid that fills the cell.


It allows substances to dissolve, and chemical reactions to take place.

Which organelle is indicated above?

Ribosome.

Answer in your head, out loud, or on paper, then tap the card to flip.

What is the role of the nucleus?

It contains the genetic material (DNA) of the cell, and so controls what the cell does.

What is the role of the mitochondria?

They carry out aerobic respiration, so provide energy (in the form of ATP) for the cell to use in chemical reactions. 

Answer in your head, out loud, or on paper, then tap the card to flip.

What is the role of the ribosomes?

They are the site of protein synthesis (where proteins are made).

Answer in your head, out loud, or on paper, then tap the card to flip.

Which organelle is indicated above?

Mitochondrion.


(if you have more than one you call them 'mitochondria')

Answer in your head, out loud, or on paper, then tap the card to flip.

Which organelle is indicated above?

Cell membrane.

Name 3 sub-cellular structures (organelles) that are found in plant cells but not in animal cells.

Cell wall, permanent vacuole, chloroplast.

Answer in your head, out loud, or on paper, then tap the card to flip.

In plants, what is the cell wall made of?

Cellulose.

Answer in your head, out loud, or on paper, then tap the card to flip.

What is the role of the plant cell wall?

It provides strength and structure to the plant cell, preventing it from bursting or shrinking when water enters/leaves the cell via osmosis. 

Answer in your head, out loud, or on paper, then tap the card to flip.

Which organelle is indicated above?

Permanent vacuole.

Answer in your head, out loud, or on paper, then tap the card to flip.

What does the permanent vacuole contain?

Cell sap (a solution of sugars, salts, and amino acids).

Answer in your head, out loud, or on paper, then tap the card to flip.

What is the role of the permanent vacuole?

It supports the cell, maintaining its turgidity (shape).

What is the role of chloroplasts?

Chloroplasts are the site of photosynthesis, so make glucose for the cell.

Answer in your head, out loud, or on paper, then tap the card to flip.

What sub-cellular structure is indicated above?

Flagellum.


(if you have more than one, you call them 'flagella')

Answer in your head, out loud, or on paper, then tap the card to flip.

What is chlorophyll?

A green pigment within chloroplasts that absorbs sunlight for photosynthesis.


It is chlorophyll that makes plants green.

Name 7 sub-cellular structures (organelles) that are found in bacterial cells.

Answer in your head, out loud, or on paper, then tap the card to flip.

What organelle is indicated above?

Plasmid.

Answer in your head, out loud, or on paper, then tap the card to flip.

What are plasmids, and what are their role?

Plasmids are small, circular loops of DNA that are separate to the main DNA.


They contain ‘extra genes’ that are sometimes useful to the bacteria, such as antibiotic resistance.
