Do protoctist cells contain nuclei?

Yes, protoctist cells have nuclei.

Are protoctists mostly single-celled or multicellular?

Mostly single-celled.

What two modes of nutrition occur among protoctists?

  • Some have chloroplasts and photosynthesise.
  • Others obtain food from other organisms or organic material.

Why does photosynthesis alone not establish that an organism belongs to the plant kingdom?

A photosynthesising organism that is mostly single-celled and has a nucleus may instead be a protoctist.

What structure surrounds fungal cells?

A cell wall.

Why do fungi not make food by photosynthesis?

Their cells lack chloroplasts.

How does nutrient acquisition differ between fungi and animals?

Fungi digest organic material outside their bodies and absorb the soluble products; animals ingest food.

What is a mycelium?

A network of thread-like hyphae that makes up the body of many fungi.
