Question

Adaptation in plants

Answer 1

Plant Adaptations

What are adaptations?
Adaptations are special features that allow a plant or animal to live in a particular place or habitat.

Plants have adaptations to help them survive (live and grow) in different areas. Adaptations are special features that allow a plant or animal to live in a particular place or habitat. These adaptations might make it very difficult for the plant to survive in a different place. This explains why certain plants are found in one area, but not in another. For example, you wouldn't see a cactus living in the Arctic. Nor would you see lots of really tall trees living in grasslands.

Desert Plant Adaptations
Some plants, called succulents, store water in their stems or leaves;
Some plants have no leaves or small seasonal leaves that only grow after it rains. The lack of leaves helps reduce water loss during photosynthesis. Leafless plants conduct photosynthesis in their green stems.
Long root systems spread out wide or go deep into the ground to absorb water;
Some plants have a short life cycle, germinating in response to rain, growing, flowering, and dying within one year. These plants can evade drought.
Leaves with hair help shade the plant, reducing water loss. Other plants have leaves that turn throughout the day to expose a minimum surface area to the heat.
Spines to discourage animals from eating plants for water;
Waxy coating on stems and leaves help reduce water loss.
Flowers that open at night lure pollinators who are more likely to be active during the cooler night.
Slower growing requires less energy. The plants don't have to make as much food and therefore do not lose as much water.

Plant Adaptations in Water

underwater leaves and stems are flexible to move with water currents
some plants have air spaces in their stems to help hold the plant up in the water
submerged plants lack strong water transport system (in stems); instead water, nutrients, and dissolved gases are absorbed through the leaves directly from the water.
roots and root hairs reduced or absent; roots only needed for anchorage, not for absorption of nutrients and water
some plants have leaves that float atop the water, exposing themselves to the sunlight
in floating plants chlorophyll is restricted to upper surface of leaves (part that the sunlight will hit) and the upper surface is waxy to repel water
Some plants produce seeds that can float


Taiga Plant Adaptations
many trees are evergreen so that plants can photosynthesize right away when temperatures rise
many trees have needle-like leaves which shape loses less water and sheds snow more easily than broad leaves
waxy coating on needles prevent evaporation
needles are dark in color allowing more solar heat to be absorbed
many trees have branches that droop downward to help shed excess snow to keep the branches from breaking

Tundra Plant Adaptations
Tundra plants are small (usually less than 12 inches tall) and low-growing due to lack of nutrients, because being close to the ground helps keep the plants from freezing, and because the roots cannot penetrate the permafrost.
Plants are dark in color—some are even red—this helps them absorb solar heat.
Some plants are covered with hair which helps keep them warm.
Some plants grow in clumps to protect one another from the wind and cold.
Some plants have dish-like flowers that follow the sun, focusing more solar heat on the center of the flower, helping the plant stay warm.

Tropical Rainforest Plant Adaptations
drip tips and waxy surfaces allow water to run off, to discourage growth of bacteria and fungi
buttresses and prop and stilt roots help hold up plants in the shallow soil
some plants climb on others to reach the sunlight
some plants grow on other plants to reach the sunlight
flowers on the forest floor are designed to lure animal pollinators since there is relatively no wind on the forest floor to aid in pollination
smooth bark and smooth or waxy flowers speed the run off of water
plants have shallow roots to help capture nutrients from the top level of soil.
many bromeliads are epiphytes (plants that live on other plants); instead of collecting water with roots they collect rainwater into a central reservoir from which they absorb the water through hairs on their leaves
epiphytic orchids have aerial roots that cling to the host plant, absorb minerals, and absorb water from the atmosphere
