CELLS: Diagrams to Label

Question 1

What is motility?

Answer 1

The ability of an organism to move independently, using metabolic energy. It is genetically determined.

Question 2

What is the difference between motility and mobility?

Answer 2

Motility is the ability of an object to move independently, whereas mobility describes the ability of an object to be moved.

Question 3

How do eukaryotic cells gain motility?

Answer 3

By flexible waving cilia or flagellae

Question 4

What does the cytoplasm contain?

Answer 4

Contains enzymes for glycolysis and other metabolic reactions, salt, sugars, amino acids, nucleotides and all other things the cell needs to function.

Question 5

What happens in the cytoplasm?

Answer 5

The first stage of anaerobic respiration (glycolysis). Also fermentation.

Question 6

What is chromatin?

Answer 6

A mass of material found in the nucleoplasm that contains the genes of the organism. It separates into chromosomes during cell division.

Question 7

Describe the features of an 80S ribosome:

Answer 7

Found in eukaryotic cells. Around 25nm in diameter.

Question 8

Describe the features of a 70S ribosome:

Answer 8

Found in prokaryotic cells, mitochondria and chloroplasts. Slightly smaller than 25nm in diameter.

Question 9

Why are cellulose cell walls so strong?

Answer 9

They are made of microfibrils of cellulose (a polysachharide), embedded within a matrix.

Cellulose cell walls have incredible strength and so contribute to the overall strength of the cell wall.

Label and state what this cell is:

Answer 10

Animal cell.

Question 11

Label and state what this cell is:

Answer 11

Plant Cell.

Answer 12

Nucleus.

Question 13

Label and state what this organelle is:

Answer 13

Chloroplast

Question 14

Label and state what this organelle is:

Answer 14

Chloroplast in depth.

Question 15

Label and state what this organelle is:

Answer 15

Mitochondrion.
