a rigid or semi-rigid stem
One: they live in water instead of land like regular plants Two: they don't need air
water,aquatic organisms,aquatic plants and saltwater
They need air, water, and sunlight.
Almost all plants need sunlight to photosynthesise. If the plant is permanently submerged, the water must be clear enough to allow sufficient light to reach the plant.
because plants need photosynthesis to live or they will die
No; they are semi aquatic. They need a floating log AND a land area. If they don't have both, they can die. so the answer is no
Carbon dioxide, water and light.
to survive on land, plants must have structures that allow them to obtain water and other nutrients from their surroundings, retain water, transport materials in their bodies, and reproduce those are the five adaptations that plants need to survive on land
For plants to survive on land, they must have ways to obtain water and other materials from their surroundings, retain water, transport materials throughout the plant, support their bodies, and reproduce successfully. :D
Rooted aquatic plants can be found in areas with lower sunlight exposure. This is because the plants are used to having limited light because they're used to being in the water.
Most aquatic plants require gravel, as they have roots, and will need to grow their roots and attach themselves. There are however lots of floating plant species that do not require gravel, such as duck weed.
