Question { 8048 }

What are the differences beetween angiosperms and gymnosperms?

Answer

1. In angiosperms there is fruit as well as seed formation.
In gymnosperm ther is only seed formation but no fruit
formation, this is the most important and major difference
between them.

2. Gymnosperms are all trees, some of them are very tall
and massive. The Angiosperms, on the other hand, can be
trees, herbs as well as shrubs.

3. Gymnosperms have Tracheids in xylem and sieve cells in
phloem , companion cells are absent. Their xylem walls have
bordered pits. In Angiosperms, true vessels i.e. tracheae
are present in xylem. Sieve tubes and companion cells are
present in phloem. Their xylem walls show simple pits.

4. Gymnosperms are more ancient than the Angiosperms.

1. Brambles which are thorny plants of the genus Rubus, in
the rose family (Rosaceae

2. An altogether faster species is the birdcage plant,

with the assistance of wind

Question { 4727 }

what is xylem composed of?

Answer

The most distinctive cells found in xylem are the tracheary
elements: tracheids and vessel elements. However, the xylem
is a complex tissue of plants, which means that it includes
more than one type of cell. In fact, xylem contains other
kinds of cells, such as parenchyma, in addition to those
that serve to transport water.

Question { 4157 }

Explain the insectivorous habit of Venus Fly trap?

Answer

The Venus Flytrap, Dionaea muscipula, is a carnivorous
plant that catches and digests animal prey—mostly insects
and arachnids. Its trapping structure is formed by the
terminal portion of each of the plant's leaves and is
triggered by tiny hairs on their inner surfaces. When an
insect or spider crawling along the leaves comes into
contact with one or more of the hairs twice in succession,
the trap closes. The requirement of redundant triggering in
this mechanism serves as a safeguard against a waste of
energy in trapping objects with no nutritional value.

Question { 5761 }

what is cliestogamy?

Answer

Cliestogamy is the pollination that occurs before the
flower opens. Cleistogamous flowers must of necessity be
self-compatible or self-fertile plants. Cleistogamous
flowers are often formed late in the year, after the
production of normal flowers, or during a period of cold
weather, as seen in several species of violet Viola.

Question { 6569 }

What is the medicinal importance of Lycopodium?

Answer

The term Lycopodium is also used to describe the yellowish,
powdery spores of certain club mosses, especially
Lycopodium clavatum, used in the past in fireworks,
fingerprint powders, and explosives and as a covering for
pills.

Question { 4002 }

What is the impotance of Bryophytes in the ecosystem?

Answer

Bryophytes play a significant role in contributing to
nutrient cycles and they also form a major component of
canopy humus.

Changes in epiphytic bryophyte assemblages affect other
canopy dwelling biota such as vascular epiphytes,
invertebrates and especially foraging birds.

Further, bryophytes are very effective rainfall
interceptors and the overwhelming abundance of epiphytic
Liverworts in"cloud" or "mossy" forest zones is considered
an important factor in eliminating the deteriorating effect
of heavy rains including helping to prevent soil erosion
and adding to hill stability.

Because of the close association of bryophytes with
climatically sensitive habitats and ecosystems, they may
serve as potential indicators of large-scale changes to the
ecosystem before the habitat or ecosystem itself is
effected.

Question { 3213 }

what is secondary growth?

Answer

In many vascular plants, secondary growth is the result of
the activity of the vascular cambium. The latter is a
meristem that divides to produce secondary xylem cells on
the inside of the meristem (the adaxial side) and secondary
phloem cells on the outside (the abaxial side). This growth
increases the girth of the plant root or stem, rather than
its length, hence the phrase "secondary thickening". As
long as the vascular cambium continues to produce new
cells, the stem or root will continue to grow in diameter.
In woody plants, this process produces wood.
