Upper antheridium and lower oogonium
Select the correct statement. (2016 Phase-I)
(A)
Gymnosperms are both homosporous and
heterosporous.
(B)
Salvinia, Ginkgo and Pinus all are gymnosperms.
(C)
Sequoia is one of the tallest trees.
(D)
The leaves of gymnosperms are not well
adapted to extremes of climate
.
Winged pollen grains are present in
(2018)
(A) Mustard
(B)
Cycas

In animals, this growth is seen only up to a certain age (limited or indeterminate growth). However, cell division occurs in certain tissues to replace lost cells.
Ÿ Unicellular organisms also grow by cell division. One can easily observe
this in in vitro cultures by simply counting the number of cells under the microscope.
Ÿ One must remember that increase in body mass is considered as growth. Non-living objects also grow if we take increase in body mass as a criterion for growth. Mountains, boulders and sand mounds do grow. However, this kind of growth exhibited by non-living objects is by accumulation of material on the surface (accretion) – extrinsic growth.
Ÿ In living organisms, growth is from inside (instrinsic growth). Growth, therefore, cannot be taken as a defining property of living organisms.
Ÿ Conditions under which it can be observed in all living organisms have to be explained and then we understand that it is a characteristic of living systems. A dead organism does not grow.
Explore the intriguing world of the plant kingdom through topics like classification by notable scientists, gamete characteristics in Phaeophyceae, unique features of Bryophytes, and the significance of Bryophytes as the amphibians of the plant kingdom. Delve into the structures and functions of plant bodies, reproductive organs, and pteridophytes, unveiling the captivating diversity within the plant world.
