Answer:

A pteridophyte is a vascular plant that disperses spores. Because pteridophytes produce neither flowers nor seeds, they are sometimes referred to as "cryptogams", meaning that their means of reproduction is hidden. Ferns, horsetails, and lycophytes are all pteridophytes.

Wind has no effect on a plants respiration rate
valentina_108 [34]

Wind has no effect on a plants respiration rate True

Where sugars are formed are referred to as the sink True

Both the xylem and phloem do not use any plant energy to translocation materials True

The amount of humidity in the air will affect transpiration True

The rate of transpiration reduces as the relative humidity of the air around the plant increases. Compared to more saturated air, dryer air makes it simpler for water to evaporate. A plant's transpiration rate will rise when air movement around it increases.

<h3>What about plants respiration?</h3>
  • Water vapor is lost via the process of transpiration through a plant's stomata.
  • When it's very hot outside, the plant loses water vapor to cool down, and water from the stem and roots flows up or is "drawn" into the leaves.
  • In addition, plant transpiration contributes significantly to the leaf's energy balance by providing evaporative cooling.
  • Additionally, the movement of water and nutrients from the roots to the shoots is accelerated by transpiration.
  • Plants use transpiration for a variety of purposes.
  • The direct effects of transpiration include controlling the plant's temperature and supplying water for photosynthesis.
  • Additionally, it facilitates the movement of glucose and nutrients through the plant's vascular tissues.
  • Plants lose water through a process known as transpiration.
  • A plant's roots can collect up to 99.5% of the water that the plant transpires, which is not used for growth or metabolism.
  • For the surroundings to remain wet, transpiration is necessary.

Tom [10]

Answer:

oxygen

Explanation:

A limiting factor is any condition whose decrease, increase, absence or presence is able to limit/stop population growth. Examples of limiting factors include abiotic conditions (e.g., temperature, water, oxygen, CO2, etc) or biotic conditions (e.g., food, mate, etc). There are many aquatic species that require high levels of oxygen (e.g., fish), thus being it a limiting factor for these species.
