Trees. Trees tend to grow much taller than grasses do because of their woody "stem" or trunk, which can hold a lot more weight than the stem of grass. Even bamboo, which is a type of grass, cannot grow as tall as most trees can.
The type of tissue that helps a plant stem stand upright is called sclerenchyma. This tissue is composed of thick-walled cells that provide structural support and rigidity. Sclerenchyma cells can be found in various forms, such as fibers and sclereids, and they contribute to the overall strength of the stem, allowing the plant to maintain its upright posture.

Peripheral blood stem cells (PBSCs) are obtained from circulating blood rather than from bone marrow, but the amount of stem cells found in the peripheral blood is much smaller than the amount of stem cells found in the bone marrow.

A type of forest with trees that do not lose their leaves is called an evergreen forest. These forests are characterized by trees that keep their leaves or needles throughout the year, providing a continuous canopy of greenery. Examples of trees found in evergreen forests include pine, spruce, and fir.
The type of cells in higher plants that have a similar function to stem cells are called meristematic cells. These cells are found in the growing tips of roots and shoots, and are responsible for cell division and growth in plants.

All trees are plants, but not all plants are trees. Trees are a specific type of plant characterized by having a single woody stem or trunk that supports branches and leaves. Plants encompass a wider range of organisms, including trees, shrubs, herbs, grasses, and more.
