In the following statement about is in which characteristic not occur in this genus.
1 The Pinus is homosporous gymnosperm, i.e. produce same type of spores
2 The number of needles in spur of Pinus roxburghii is three
3 Each vascular bundle in the long shoot of Pinus consists of xylem facing towards the centre of the shoot
4 Microsporophyll of Pinus bear two micro sporangia
Explanation:
In gymnosperms, plants are heterosporous i.e. produce two kinds of spores: microspore (male) megaspore (female). Microspore and megaspore germination is in-situ, producing micro- and megagametophytes which are not autotrophic, and gymnosperms are not homosporous. Pinus is a monoecious gymnosperm that produced both male and female cone on the some plant as well as male and female strobili on distinct strobili.

The following species of Cycas is recorded in the forests of A.P.
1 Cycas revoluta
2 Cycas pectinata
3 Cycas beddomei
4 Cycas thomsonii
Explanation:
In the forest of Andhra Pradesh, the cultivated species of cycas is cycas beddomei. It is grown mainly on Tirupti hills of Andhra Pradesh. Superficially similar to cycas revoluta, it has erect, solitary stem. The cycad in found in dry hot sites in the serublands of eastern India clumps of the plant are common vie pups only in mates. The plant is fairly free resistant, except as seeds and seedling, which are very vulneroble to annual grass fires.

The term gymnosperm was introduced by
1 Aristotle
2 Mendel
3 Pasture
4 Theophrastus
Explanation:
The tern gymnosperms was first introduced Theophrastus in 300 B.C. in his book "Enquiry into plants". Gymnosperm is derived from two Latin words. The term gymnos refers to naked and term sperms refers to the seed. These are seed producing plants in which the seed is found in an unclosed condition.

Many xerophytes accumulate this in response to stress
1 Glucose
2 Proline
3 Lysine
4 Fatty acids
Explanation:
Many xerophytes accumulate this in response to stress by proline. In order to trade over the stress phase, many xerophytes make suitable morphological and physiological adaptations. Accumulation of free proline under water deficit is one such physiological response.
