Plant growth and development

A few normal seedlings of tomato were kept in a dark room. After a few days they were found to have become white-coloured like albinos. Which of the following terms will you use to describe them?
1 Mutated
2 Embolised
3 Etiolated
4 Defoliated
Explanation:
C Etiolation involved prolonged growth in the absence of light. Etiolation is a process in which flowering plants are grown in the partial or complete absence of light. Etiolation is mainly characterised by the long and weak stem and smaller, sparse pale yellow colour (chlorosis) leaves due to longer internodes. Etiolation is performed by phytohormones such as auxin, gibberellins Hence, the tomato seedlings when kept in the darkroom were found to become white coloured like albinos.

Opening of floral buds into flowers, is a type of:
1 Autonomic movement of growth
2 Autonomic movement of locomotion
3 Autonomic movement of variation
4 Paratonic movement of growth
Explanation:
A Opening of floral buds into flowers, is a type of autonomic movement of growth. Movement may be of two types, movement of locomotion and movement of curvature. - Opening of floral buds into flowers is such a type of growth movement. - Movement of curvature is movement of individual parts in relation to other parts. - Curvature movement may be growth movement and turgor movements. - Growth movements are caused by differential growth in different part of an organ. - Inner surface or upper surface of floral leaves expand towards outer side due to more cell growths. This makes the flower to open.

Auxetic growth is increase in
1 cell volume only
2 cell number only
3 fatty tissue
4 intercellular material
Explanation:
A Three type of growth are present in multicellular animal 1.Auxetic growth - Increase in cell volume only not in number 2.Multiplication growth - Increase in number not a volume 3.Accretionary growth - Growth due to mitotic division of some special type of cell occurring in specific location.
