Plant cell
There are three major classes of plant cells that can then differentiate to form the tissue structures of roots, stems, and leaves. (The three distinct types of plant cells are classified according to the structure of their cell walls and features of their protoplast. Plants will have a primary cell wall and sometimes a secondary wall as well. These two major parts are what determines the function of each individual plant cell.)
The tissue types are: Dermal tissue - the outer most covering of a plant; Vascular tissue - Responsible for transport of materials throughout the plant; Ground tissue - Performs photosynthesis, starch storage and structural support.

Oct. 5, 2026 Predatory wasps are hijacking shelters built by tropical trees for their ant defenders, potentially disrupting an ancient partnership that protects the plants from hungry insects. The takeover is far more common in disturbed landscapes such as oil ...
Oct. 5, 2026 Scientists found that prolonged fasting triggers major changes throughout the body, but many of the most interesting effects only appeared after about three days without food. The results suggest fasting may influence health in ways that go beyond ...
Oct. 5, 2026 Scientists have discovered a human gene with a remarkable double life: it appears to play an important role in brain cells while still retaining the ability to jump around the genome. Called BC200, the gene evolved millions of years ago from a ...
Oct. 4, 2026 Scientists have discovered that E-cadherin, a protein best known as the “glue” holding cells and tissues together, has a surprising second job: helping epithelial cells swallow nearby dead cells. Using live zebrafish and mouse embryos, ...
Oct. 4, 2026 A 30-year forestry experiment in Australia found that heavily thinned mountain ash forests grew unusually large trees while recovering enough carbon to match or exceed untouched areas. The results suggest carefully managed thinning could support ...
