The first plants in a novel environment
will be algae, lichen, and bryophytes. These plants are referred to as pioneer
plants. After these plants have broken down the rocks, and begin to form soil,
then you begin to see plants such as
herbs, ferns, and grasses. Eventually, vascular plants will be found in
the habitat.
New environments, such
as those formed by a lava flow from
volcanos, are majorly comprised of rocks.
These are not an ideal substrate for higher plants since they do not form
a great substrate
for anchoring of the plant and the plants are unable to reach and take up the nutrient held
in the rocks. Pioneering plants’ roots are able to penetrate
the small crevices in rocks and cause mechanical weathering. These plants also secrete organic acids that chemically weather the rocks hence are significant
in soil formation and release of nutrient from the rocks (nutrient cycling).

The male reproductive gland that is missing in the cat but present in the human is the seminal vesicles. In cats, a small prostrate gland surrounds the point of entrance of the two ductus deferens and the adjacent urethra. At the caudal end of the pelvic canal, a pair of Cowper's glands enter the urethra canal. The male cat does not have a seminal vesicle as the case in human male.
Answer:
The appearance of the mycobacterium is like rod shaped.

Cell wall is the cell component which correlate with mycobacterium. The structure of cell wall is thick and made up of several layers of peptidoglycan which is formed from sugar and amino acid molecules.
