Katena32 [7]

The question is incomplete and the complete question is:

For each space in the table, drags the appropriate label to indicate if the statement is true or false for each group of organisms

1. Cells divide by constriction of a ring of protein

2. The presence of a cell wall prevents the cell from diving by constriction

3. Tubulin or tubulin-molecules function in binary fission(in bacteria) or cytokinesis(in animals and plants)

Answer:

1. Bacteria: true , Animals: true  and Plants: false

2 bacteria: false , Animals: false and Plants: true

3. Bacteria: true , Animals: false  and Plants: true

Explanation:

Option-1

Bacteria: true  as the protein FtsZ is involved in the binary fission and the formation of constriction.

Animals: true  as the microtubule ring is formed

Plants: false  as no constriction of the ring is formed instead of a cell divides by plate formation

<u>Option-2</u>

<u> </u>Bacteria: false  as the ring is formed and no cell wall is involved

Animals: false as there is no cell wall in the animals

Plants: true as the cell wall divides by plate formation

Option-3

Bacteria: true  as FtsZ is involved in the ring formation which is tubulin like structure

Animals: false  as the actin and myosin are involved in a ring formation

Plants: true as tubulin are involved
