l h e potential for photosynthetic and photoautotrophic growth

was studied in hairy root cultures of Asteraceae and Solanaceae

species. Upon transfer to light, initially heterotrophic root cultures

of Acmella oppositifolia and Dafura innoxia greened rapidly, dif-

ferentiated chloroplasts, and developed light-dependent CO, fix-

ation in the cortical cells. Photosynthetic potential was expressed

in root cultures of all the Asteraceae genera examined (Acmella,

Artemisia, Rudbeckia, Sfevia, and Tagetes). Hairy roots of A. op-

positifolia and D. innoxia were further adapted to photoautotrophy

by growing in the presence of light and added CO, (1-5%) and by

direct or sequential transfers into media containing progressively

lower sugar concentrations. l h e transition to photoautotrophy was

accompanied by an increase in COz fixation and in the specific

activity of 1,s-ri bulose-bisphosphate carboxylase/ oxygenase (Rub-

isco). During the adaptation of A. opposififolia roots to photoau-

totrophy, the ratio of Rubisco to phosphoenolpyruvate carboxylase

increased significantly, approaching that found in the leaves. l h e

levels and patterns of alkaloids and polyacetylenes produced by

Solanaceae and Asteraceae hairy roots, respectively, were dramat-

ically altered in photomixotrophic and photoautotrophic cultures.

Photoautotrophic roots of A. opposififolia have been maintained

in vitro for over 2 years.:P

Where does water come from in the process of photosynthesis?

Water is absorbed by plants from the soil through their roots, and it is then transported to the leaves where it is used in the process of photosynthesis.


What process is not involved in moving water from roots to leaves in a plant?

Photosynthesis. The process of moving water from roots to leaves is called transpiration through a process known as the transpiration stream. Photosynthesis is the process where plants convert light energy into chemical energy to produce glucose.


What is the source of water in photosynthesis?

The source of water in photosynthesis is typically taken up by the plant's roots from the soil. This water is then transported through the plant to the leaves where it is used in the process of photosynthesis.


How is water utilized in the process of photosynthesis?

Water is essential for photosynthesis, a process in which plants use sunlight to convert carbon dioxide and water into glucose and oxygen. During photosynthesis, water is absorbed by plant roots and transported to the leaves where it is split into hydrogen and oxygen molecules. The hydrogen is used to help convert carbon dioxide into glucose, while the oxygen is released into the air as a byproduct.


How do plants obtain the water they need for photosynthesis?

Plants get the water they require for photosynthesis by absorbing from the soil through their root systems. It is then transported up the stem and to the leaves where is is used to synthesise sugars through photosynthesis.

What do the roots do for the flower?

Roots bring water and nutrients to the whole plant. Without water to " crack " the process of photosynthesis would not be possible. Also, roots help keep the plants upright and/or in a fixed location.


Does the photosynthesis take place in the leave or in the roots?

in the leaf.it takes in sunlight to start the process of photosynthesis

How does the absorption of water by roots helps photosynthesis to take place?

Absorption of water by roots helps in the process of photosynthesis by providing the necessary hydration for the plant's cells. Water is a crucial component in the photosynthesis process, as it is used in the light-dependent reactions to split water molecules and release oxygen. Without water uptake by roots, plants would not have the means to transport nutrients and maintain turgidity for photosynthesis to occur efficiently.


Is food made through the plant roots?

No. It is made by the stomata in the leaves. This process is called photosynthesis.

Are roots involved in food production of a plant?

Yes, roots play a critical role in the food production of a plant through the process of photosynthesis. Plants absorb water and nutrients through their roots, which are essential for photosynthesis to occur in their leaves. This process converts light energy into food (glucose) that the plant uses for growth and survival.


Do roots have chloroplast?

No, roots do not have chloroplasts. Chloroplasts are typically found in plant leaves and are responsible for photosynthesis, which is the process of converting sunlight into energy for the plant. Roots are mainly responsible for absorbing water and nutrients from the soil.
