Answers
1. The two main modes of nutrition is autotrophic and heterotrophic.
2. Indian pipe
Corallorhiza orchids
3. The products of photosynthesis are glucose and oxygen.
4. Corpse Flower
Dodder
5. Venus flytrap
Waterwheel plant
Answer:
answer 1 There are two modes of nutrition: Autotrophic – Plants exhibit autotrophic nutrition and are called primary producers. Plants synthesis their food by using light, carbon dioxide and water. Heterotrophic – Both animals and human beings are called heterotrophs, as they depend on plants for their food.
answer 2 Examples saprophyte plants include:
- Indian pipe.
- Corallorhiza orchids
answer 3 The products of photosynthesis are glucose and oxygen.
Although the hydrogen atoms from the water molecules are used in the photosynthesis reactions, the oxygen molecules are released as oxygen gas (O2).
answer 4 plant usually considered holoparasites include broomrape, dodder, Rafflesia, and the Hydnoraceae. Plants usually considered hemiparasites include Castilleja, mistletoe, Western Australian Christmas tree, and yellow rattle.
answer 5 Insectivorous plants include the Venus flytrap, several types of pitcher plants, butterworts, sundews, bladderworts, the waterwheel plant, brocchinia and many members of the Bromeliaceae.
