Introduction to Botany

Natural selection favors plants with advantageous traits, allowing them to survive and reproduce more effectively in their environment. This leads to the gradual accumulation of beneficial mutations and the diversification of plant species over time.

Plant genetics enables us to understand the inheritance of desirable traits in crops, allowing for the development of new varieties with enhanced yield, disease resistance, and nutritional value. Genetic manipulation techniques can further enhance these improvements.

Mycorrhizae are symbiotic relationships between fungi and plant roots. The fungi help plants access nutrients from the soil, while the plants provide the fungi with carbohydrates. This mutually beneficial partnership enhances plant growth and survival.

<p>Economic botany investigates and utilizes plants for food production. Through the study of crop plants and their cultivation techniques, we can optimize food production and ensure a sustainable food supply for the growing global population.</p> Signup and view all the answers

<p>Plant interactions involve predator-prey relationships between plants and animals. Herbivores consume plants, while plants have developed defense mechanisms like thorns or toxins to deter herbivory. This ongoing evolutionary arms race shapes both plant and animal adaptations.</p> Signup and view all the answers
