What two plants have no true stem or roots or leaves?
Algae and mosses are two examples of plants that can lack true stems, roots, and leaves. These plants typically have simple structures that allow them to absorb nutrients and carry out photosynthesis.
How are algae and plants different?
Algae are simple, photosynthetic organisms that lack true roots, stems, and leaves, while plants are more complex and have specialized structures for different functions. Moreover, algae do not have reproductive structures like flowers, fruits, or seeds, while plants do. Additionally, algae can range from single-celled to multicellular forms, whereas plants are mostly multicellular.
How do plants with weak stems grow?
Plants with weak stems are either creepers, climbers or twinners. Very often these plants have specialized structures like tendrils, climbing roots or hooks to push them up to get more sunlight.
How do you multiply chrysanthemums?
When they are beginning to come up, you gently pull the plants out and pull them into large sections that include both stems and roots. Then you carefully replant these new plants.
What organs did the earliest plants have?
The earliest plants, known as bryophytes, had simple structures with no distinct organs like leaves, stems, or roots. They had a structure called a thallus which served as a basic form of a plant body to absorb nutrients and water. Over time, as plants evolved, they developed more complex structures with specialized organs.
Compare and contrast vascular and nonvascular plants.?
Plants vascular have tubelike structures that carry water, nutrients and substances throughout the plant; Plant non vascular do not have these tubelike structures and use other ways to move water and substances. Terry Abraham, 11 ans
Why are leaves more well adapted for photosynthesis than stems or roots?
because they are filled with glucose
Which tissues is common in roots but not in stems?
Roots typically have root hairs, a tissue not found in stems. Root hairs are thin extensions of root epidermal cells that increase the surface area for absorption of water and nutrients from the soil.
Where can someone find out more information on grass roots?
One can find more information on grass roots by reading the Plants Today magazine. They go into great detail about certain plants such as grass roots.
What roots do in transpiration?
Roots absorb water from the soil and transport it to the rest of the plant. This water then moves through the plant, eventually reaching the leaves where it evaporates through tiny openings called stomata in a process known as transpiration. Roots also help in maintaining the plant's water balance and nutrient uptake.
Why do plants loose more water than it is absorbing from the soil?
Plants loose more water than they absorb from the soil due to a process called transpiration. is the evaporation of water into the atmosphere from the leaves and stems of plants. Plants absorb water through their roots and this water can originate from deep in the soil. (For example, corn plants have roots that are 2.5 meters deep, while some desert plants have roots that extend 20 meters into the ground). Plants pump the water up from the soil to deliver nutrients to their leaves. This pumping is driven by the evaporation of water through small pores called stomates, which are found on the undersides of leaves. Transpiration accounts for approximately 10% of all evaporating water.Read more: Why_do_plants_loose_more_water_than_it_is_absorbing_from_the_soil
What are different types of stem?
One of the different types of stems is the Herbaceous stems. These are often found on annual plants. Ligneous stems are more woody, and often found on shrubs.
