Frequency of bean plants in the garden that have been eaten can be calculated as the total number of bean plants eaten divided by the total number of all bean plants in the garden.
Number of bean plants eaten = 45; number of bean plants uneaten = 5
Total number of bean plants in the garden = 45 + 5 = 50
Therefore, frequency of bean plants in the garden that have been eaten = 45/50 = 0.9 = 90%
Frequency of bean plants eaten in the garden by the deer = 90%
Secondary metabolites are organic compounds produced by plants or fungi or bacteria which are not use for growth and development of plants or for reproduction purposes but are use as defence mechanism against attacks and for survival in their environment. They are also use as metal transporting agents and sex hormone.
Examples of the secondary metabolites are terpenes, phenolics and nitrogen containing compounds.
these are secondary metabolites
These secondary metabolites are chemical compounds found in some fungi, bacteria and some plants. They are not involved in true normal growth and other processor in these organisms, but they often help protect plants from herbivory and these include terpenes, alkaloids, phenols etc.
Have a nice day :)

The more water stored in the vacuole, the more structural support plants receive. THis is why plants wither (lose structure) when they have not been watered.
They keep buds inactive in winter, speed up the growth of plant cells, and ripen fruits.
Plant hormones or phytohormones are substances produced by plants that act in the regulation of their development and growth. The function of hormones is to act as "chemical messengers" between cells, tissues and organs of higher plants.
The hormones act in specific places, in order to trigger an action. This action is varied, since each hormone has a specific and particular function, but if we can summarize the functions of the hormones, we can mention that they keep the buds inactive in winter, accelerate the growth of plant cells and ripen the fruits.
Xylem developed to transport water from the plant’s roots to the rest of the plant.
A waxy cuticle is usually present to reduce water loss, whereas spines are often in place that help plants avoid being eaten by herbivores.
Stomata are key for gas exchange, and actually permit the release of water. Water is taken up through the roots, not the stomata
All plant cells have nuclei, which is the organelle in which DNA is stored. The seeds did not develop to provide a place for the storage of genetic information.
However, the xylem is an important part of the plant vascular transport system that ensures water is transporter from the roots to the leaves. This is an important adaptation for land plants as it ensures all parts of the plant get a water supply, particularly the leaves that are undergoing photosynthesis.
