Spermatopsida, or seed plants, are successful land plants primarily due to their ability to produce seeds, which provide protection and nourishment to the developing embryo, enhancing survival rates in diverse environments. Additionally, their development of vascular tissues allows for efficient water and nutrient transport, enabling them to thrive in various habitats and outcompete non-vascular plants. These adaptations have facilitated their widespread distribution and dominance in terrestrial ecosystems.

Why are the wounds required for successful transmission of plant viruses?
Wounds are required for successful transmission of plant viruses because they provide an entry point for the virus to bypass the plant's protective barriers, such as the cell wall and plasma membrane. When a plant is injured, it can release cellular contents that facilitate virus movement and replication. Additionally, vectors like insects often introduce viruses through feeding wounds, enabling direct access to the plant's vascular system. This mechanism highlights the interplay between plant stress and viral infection.
What is compensation point?
The compensation point is the specific light intensity at which the rate of photosynthesis equals the rate of respiration in plants. At this point, there is no net exchange of oxygen or carbon dioxide, meaning the plant neither gains nor loses biomass. It is a crucial threshold for plant survival, as below this point, photosynthesis cannot sustain the plant's energy needs. The compensation point varies among different plant species and environmental conditions.
Would a plant still grow at the light compensation point?
Yes, a plant can still grow at the light compensation point. The light compensation point is the level of light intensity at which the rate of photosynthesis equals the rate of respiration in a plant. At this point, the plant is able to produce enough energy through photosynthesis to sustain its growth and metabolic processes.
Which part of the plant does the pollen grain need to land?
The pollen grain needs to land on the stigma of the plant for successful pollination to occur.
What is the plant part that is formed by the successful union of the male pollen cell and female ovule and thus carries characteristics of both parents?
The plant part that is formed by the successful union of the male pollen cell and female ovule is called a seed. Seeds contain genetic material from both parents and have the potential to grow into a new plant.
