Senescence as an active developmental cellular process in the growth and functioning of a flowering plants, is indicated in
1 vessels and tracheid differentiation
2 leaf abscission
3 annual plants
4 floral parts
Explanation:
B Senescence as an active development cellular process in the growth and functioning of a flowering plants, is indicated in leaf abscission. Senescence is a metabolic process, therefore it requires energy. It is not simply the ending of growth. Leaves, for example, move the product of photosynthesis- and their own structural substances out of leaf tissue into stem and root tissue during senescence and before their vascular connections are served at abscissions.

At which stage the enzymatic actions start in plant?
1 Germination
2 At the time of photosynthesis
3 At the time of flower establishment
4 At the time of fertilization
Explanation:
A At germination stage the enzymatic actions starts in plant. Any enzymatic action that participates in purging DNA of damaged elements and returns it to its canonical form.

Plant response to environment is mainly through
1 induction of dormancy
2 abscission of parts
3 synthesis of pigments
4 growth
Explanation:
D Plant response to environment is mainly through growth. The response of an organism, usually, a plant, to an environmental stimulus is called a tropism. Some plant stimuli include light, gravity, water, movement of the sun, and touch. The naming of the tropism is associated with the stimulus.

Growth is an irreversible process seen at all organizational levels. It consists of
1 organ growth
2 subcellular growth
3 cell growth
4 All of the above
Explanation:
D Growth is an irreversible process seen at all organizational level. It consists of organ growth, subcellular growth and cell growth. It occurs by a rise in cell size or number. In animal, growth rate is observed upto a certain period of time. Whereas plants show continuous growth throughout the lifetime. Growth is the most fundamental characteristic of living organism and various metabolic process that happen at the value of energy.
