What is an amoebas Mrs gren?

Answer 1

M- move by flowing of cytoplasm over the surface i.e mud, soil.

- pseudopods - changing the shape of their body.

R-"breathes" using a porous cell membrane (oxygen in - carbon dioxide out)

S- no special sense organs.

- changes in outside world detected by all parts of living material

- limited sensitivity e.g. moves away from light, but it has no photodetectors or eyes

N- food is engulfed by pseudopods (False foot) - forms a food vacuole.

- eat algae, bacteria, other protozoans, tiny particles of dead plant / animal matter

E- ingestion and egestion can take place at any point on the surface

- no 'mouth' or 'anus'.

R- a parent cell divides (Nucleus + cytoplasm divide)

= two smaller daughter cells i.e. asexually by binary fission

G- grows from nutrition - digesting food.

Answer 2

Mrs. Gren is an acronym for the seven life processes that define living organisms: Movement, Respiration, Sensitivity, Growth, Reproduction, Excretion, and Nutrition. Amoebas are unicellular organisms that exhibit these characteristics and are considered living beings because they fulfill the criteria of Mrs. Gren.
