Answer 1

A1 cascutta.

A2. some Orchids parasitise upon fungal hyphae, and do not have chlorophyll themselves Gastrodia genus is one such. It draws its food from a fungus.

Broom rape is another common weed which shares this characteristic. These epiparasites draw their food from the roots of other plants.

Quite separately, there are Brown and Red seaweeds which each use a pathway different from chlorophyll to split water into H and O.

Answer 2

Three types of higher plant spring to mind which are NOT fungi which do not manufacture their own food via photosynthesis:

Parasitic plants which use the water and nutrients of their host plants to survive.

Saprophytic plants which are plants (not fungus) that have no chlorophyll and no green coloring. They get all their nutrients from decaying organic matter. However, more recent research has decided that many so called saprophytic plants are now parasitic (such as various orchids) as they gain their nutrients by being parasitic on fungi which are involved in breaking down the organic matter.

Carnivorous plants which obtain some or most of their nutrients (but not energy) from trapping and consuming animals or protozoans such as Venus fly trap and pitcher plant
