How would shoot and root growth be affected by a mutation that caused plants to lose the ability to polymerize glucose into starch granules select all that apply?

How would shoot and root growth be affected by a mutation that caused plants to lose the ability to polymerize glucose into starch granules? Lateral branch shoots would grow more upright and be less able to maintain a horizontal orientation.

What is responsible for most of the uptake of water and nutrients performed by roots?

3. Actually, most water and nutrients are absorbed by ‘roots hairs’,a hair-forming cell on the epidermis of a plant root. They are found only in the region of maturation of the root, and the structures allow a plant to get water and nutrients from the soil.

Which of the choices was an evolutionary innovation that contributed to the successful colonization of land by the first terrestrial plants?

The evolution of a waxy cuticle and a cell wall with lignin also contributed to the success of land plants. These adaptations are noticeably lacking in the closely related green algae—another reason for the debate over their placement in the plant kingdom.

When legumes with nitrogen fixation nodules are given chemical fertilizers with high nitrogen concentrations they abandon support of the nodules and end the symbiosis Why?

When legumes with nitrogen-fixation nodules are given chemical fertilizers with high nitrogen concentrations, they abandon support of the nodules and end the symbiosis. Why? The plant can conserve valuable energy sources by terminating the symbiotic relationship.

What causes Rhizobium?

The bacteria enter the roots of legumes through, for example, root hairs or tears. They cause an infection which result in nodules on the roots. The Rhizobium bacteria take in nitrogen from the atmosphere and turn it into ammonia (NH3), a kind of natural fertiliser for the plant.

What is Rhizobium and how does Rhizobium help farmers?

Rhizobium is a bacterium found in soil that helps in fixing nitrogen in leguminous plants. It attaches to the roots of the leguminous plant and produces nodules. These nodules fix atmospheric nitrogen and convert it into ammonia that can be used by the plant for its growth and development.

How do you use Rhizobium?

Ensure intimate contact between the inoculant and seed. The rhizobia have to penetrate the root within 24–72 hours. Don’t separate the inoculant from the seed. Sow the seed within 6 hours after treatment.

What is the other name of Rhizobium?

The technical name of these bacteria is Rhizobium leguminosarum.

Why are the Rhizobium bacteria beneficial to plants?

Rhizobia have the capacity to fix nitrogen (N2) from the atmosphere. These bacteria live either freely in the soil or in beneficial association with leguminous plants, including important crops such as peas, beans and soybeans. The ammonia is in turn converted to plant proteins.

What are some nitrogen fixing plants?

Some nitrogen fixing herbaceous plants include:

  • Fava Beans.
  • Green Beans/ French Beans.
  • Runner Beans.
  • Garden Peas.
  • Field Peas.
  • Pigeon Peas.
  • Soybeans.
  • Peanuts/ Groundnuts.

What is the function of nitrifying bacteria in soil?

Summary. Nitrifying bacteria convert the most reduced form of soil nitrogen, ammonia, into its most oxidized form, nitrate. In itself, this is important for soil ecosystem function, in controlling losses of soil nitrogen through leaching and denitrification of nitrate.
