What gives rise to root?

Plant embryogenesis establishes a very simple structure that contains two stem cell populations: the shoot meristem, which will give rise to all the “above-ground” organs such as the stem, the leaves and the flowers, and is the site of photosynthesis; and the root meristem, which gives rise to the root system, which …

In which area is the concentration of auxin most likely the highest?

the concentration of Auxins is highest at the tip of the plant and lowest at the roots. What are the functions of an Auxin? 1. They promote growth by stimulating cell division(mitosis) and cell elongation which will effectively bring about growth.

What is Phototropism in plants?

Phototropism, or the differential cell elongation exhibited by a plant organ in response to directional blue light, provides the plant with a means to optimize photosynthetic light capture in the aerial portion and water and nutrient acquisition in the roots.

Which shows the correct order of steps involved when auxin affects plant growth?

1 – Auxin builds up in the stem. 2 – The stem bends toward light. 3 – Auxin moves to the shaded side of plant. 4 – Cells on the shaded side grow more quickly.

What part of a plant grows upward?

shoots

What are three types of roots?

Plants have three types of root systems: 1.) taproot, with a main taproot that is larger and grows faster than the branch roots; 2.) fibrous, with all roots about the same size; 3.) adventitious, roots that form on any plant part other than the roots.

What are the 2 types of roots?

There are two main types of root systems. Dicots have a tap root system, while monocots have a fibrous root system, which is also known as an adventitious root system. A tap root system has a main root that grows down vertically, from which many smaller lateral roots arise.

Why potato is a stem not root?

Potato is considered as a stem vegetable because it grows in underground stems, known as stolons. Potato tubers are considered to be thick stems that have the buds sprouting stems and leaves. Roots do not possess the above mentioned attributes and hence, potato is considered as a stem and not a root.

The first slice, clean through the root end. Note in the photo above that the layers of each half of the onion are held together at the root end.

Is Ginger a stem or root?

Ginger is a stem which can be differentiated from root because it (1) Grows parallel to ground (2) Stores food (3) Lacks chlorophlly (4) Has nodes and internodes. Ginger or Zingiber officinale is an example of underground stem or rhizome modifications which have nodes and internodes.

Why Ginger is a modified stem?

Complete Answer: – Rhizome of ginger is a modification of stem in vascular plants because it bears internodes and nodes. – Rhizome is found under the ground and they send roots and shoots with the help of nodes outside the ground. The other name of rhizomes is the creeping root stalks of the plant.

Does ginger have underground stem?

Underground stems are modified plant structures that derive from stem tissue but exist under the soil surface. Ginger is an underground stem and not root because it has nodes and internodes and not because it lacks chlorophyll, it stores food and had vessels and xylem.

Is Ginger The root of the plant?

Ginger (Zingiber officinale) is a flowering plant whose rhizome, ginger root or ginger, is widely used as a spice and a folk medicine. It is a herbaceous perennial which grows annual pseudostems (false stems made of the rolled bases of leaves) about one meter tall bearing narrow leaf blades.

How do you know when Ginger is ready to harvest?

Once the plant has blossomed, the rhizomes are mature enough for harvesting, usually in about 10-12 months from sprouting. At this juncture, the leaves have yellowed and dried and the stems are falling over. The rhizomes will have a firmer skin that will bruise less easily when handling and washing.
