Let’s take a look at why plants are important in our ecosystem.
Not only do plants provide oxygen through photosynthesis but they also absorb carbon dioxide. They help maintain the balance of gases in the atmosphere. We, humans, also eat plants as food; and animals as well. Plants are important for soil fertility and wow, oh wow, numerous plants have medicinal benefits. Additionally, plants prevent soil erosion. They also act as raw materials for industries such as paper, clothing, and construction.
What Do Plants “Eat”?
Plants don’t “eat” like us and other animals. They absorb nutrients and energy in different ways:
- Photosynthesis: Plants use sunlight, carbon dioxide, and water to produce glucose (food) and oxygen.
- Mineral Absorption: Through their roots, they absorb minerals like nitrogen, phosphorus, and potassium from the soil.
- Water Intake: Plants absorb water through their roots. This is important for the transport of nutrients.
Plants make their own food through photosynthesis, which occurs in their leaves.
Why Are Most Plants Green?
Most plants are green because of chlorophyll, the pigment that absorbs light for photosynthesis.
Carnivorous Plants
Carnivorous plants eat insects. They trap and digest insects and small animals. to supplement their nutrient intake, especially in poor soil conditions. They have special adaptations such as trigger hairs, strong digestive juices, bright colours to attract insects, and sticky leaves. Examples include:
- Venus Flytrap: Closes its leaves around prey.
- Pitcher Plant: Has a deep cavity filled with digestive fluids.
- Sundew: Has sticky tentacles that trap insects.
Plant Adaptations Examples
Plants survive because of various adaptations, for example cactus are able to survive in extremely hot climates because they store water in their thick stems. They have spines instead of leaves, helping to reduce water loss.
Other plants are adapted to environments of extreme cold. Such plants grow close to the ground to avoid strong winds, while others grow close together to conserve heat. They can also have needle-like leaves. Examples are the artic moss. Now let’s take a look at aquatic plants. These are plants that grow underwater. They usually have thin and flexible stems, and these helps them go with the flow of the water. Others, like the water hyacinth, have tiny air pockets inside their stems and leaves. Think of these like tiny balloons that help the plant float on water. Exciting huh! These different adaptations help plants survive in harsh climates and not so regular environments!
