Question

Explain nutrition in single cell animal

Answer 1

Nutrition in singal cell animals:

They are single celled organisms like Amoeba and they have a large surface area to volume ratio. They obtain nutrients by diffusion, facilitated diffusion or active transport across their cell membrane.

They use holzoic nutrition, taking in larger molecules by endocytosis to food vacuoles which then fuse with lysosomes and their contents are then digested by lysosomal enzymes.

The products of digestion are then absorbed into the cytoplasm and anthing indigestible is egested by exocytosis. `

Answer 2

Single celled organism like Amobea . They obtained their nutrition by the process of diffusion.

They use holozoic nutrition by taking in large molecules by endocytosis to food vacoule which then fuse with lysosomes and their content are then digested by lysosomes enzymes.

The product of digestion are then absorbed into cytoplasm.
