PLANT REPRODUCTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Nonvascular plants need to remain quite small for a number of reasons. Which of the following is not one of them?
A
In order for fertilization to take place, sperm must actually swim through water to a female plant.
B
They produce seeds that would be too heavy for the plant to support if it were larger.
C
They don’t have true roots, stems, or leaves, so many life process would not occur efficiently enough to support a larger plant.
D
They must absorb water and nutrients directly into all of their tissues from the environment.
Explanation: 

Detailed explanation-1: -Nonvascular plants are very small because their lack of a vascular system means they do not have the mechanics required for transporting food and water far distances. Another characteristic of nonvascular plants that sets them apart from vascular plants is that they lack roots.

Detailed explanation-2: -Nonvascular plants survive only in moist habitats. They do not have leaves, roots, or stems, they are low-growing plants, and they reproduce by forming spores.

Detailed explanation-3: -The non-vascular plants usually grow very close to the ground for the easy uptake of water and also to get enough nutrients present in the ground for the life process. These plants do not have true roots for the uptake of water and minerals.

Detailed explanation-4: -They are generally small plants limited in size by poor transport methods for water, gases and other compounds. They reproduce via spores rather than seeds and do not produce flowers, fruit or wood. Some non-vascular plants have developed specialized tissue for water transport and other substances.
