Q:

How do plants adapt to their environment?

A:

Plants adapt to the environment by modifying their leaves, stem and roots. Desert plants such as the cactus modify their leaves into thorns to prevent loss of moisture through transpiration. Plants such as the lotus grow in water, have modified stems with pores and have short roots.

Plants growing in dry, arid regions have long tap roots that allow them to search deep underground for moisture. In very cold regions, the leaves of plants are needle-shaped. Plants that grow in tropical rainforests have broad leaves to allow more transpiration to take place, as the humidity levels are very high.

Desert plants are called xerophytes, while plants growing in water are called hydrophytes. Mesophytes are plants that grow in regions with moderate amounts of precipitation.

  • Q:

    When does photosynthesis occur?

    A:

    Photosynthesis, the process by which plants convert the sun's energy to glucose, takes place during daylight hours when the plant's leaves are exposed to sunlight. This process only occurs in green plants and in some protist species. Carbon dioxide and water must also be present in order for photosynthesis to occur.

  • Q:

    How do cactuses adapt to their environment?

    A:

    According to the BBC, cacti have widespread, hardy root systems that collect as much water as possible in the area. Their enlarged stems can also store water and are fully capable of photosynthesis. A waxy, tough substance called the cuticle covers the plant and protects from dehydration.

  • Q:

    How do plants adapt to the tundra?

    A:

    The few plants that grow in a tundra biome have adapted by remaining dormant in the long, extremely cold winter season and taking advantage of the short summer months to grow and propagate. The plants have shallow roots, are able to perform photosynthesis even in cold temperatures and have small leaf structures.

  • Q:

    How do plants adapt to cold weather?

    A:

    The National Snow and Ice Data Center explains that different species of plants adapt to cold weather in a variety of ways, such as growing in forms that shed snow readily or by retaining dead leaves to help insulate the plant. Unlike birds and other animals that can migrate to avoid harsh winter weather, plants must find a way to cope with the cold temperatures without leaving.
