Thigmotropism,is the directional response of a plant organ to touch or physical contact.This phenomenon is shown by the climbing of tendrils in plants like vines. so D is the answer
Answer;
-Organic molecules could be produced apart from living organisms using inorganic materials.
Explanation;
-Fredrick Wohler, a German chemist attempted to make an inorganic salt, ammonium cyanate, by mixing solutions of an ammoniun ions and cyanate ions. He was astonished to find that instead he had made urea, an organic compound present in Urine animals. Then later, Kolbe made the organic compound acetic acid from inorganic substances that could be prepared directly from pure elements.
-After these discoveries and several decades of laboratory synthesis of some increasingly complex organic compounds, the Vitalists crumbled completely.
Answer: Nuclear membrane
Explanation:
The extracellular matrix can be defined as the matrix that lies outside the cell. It includes all membranes or external coverings and fluid which separates the cell from its exterior. The extracellular matrix is important for adhesion, and communication between cell to cell. This helps the cell to connect with the other substratum. The cell wall is the external layer around the plant cell which separates the plant cell from its external environment. It maintains the structure of the plant cell. The cuticle is the thick layer of cells which separates the cells from the external environment. The basement membrane is sheet of cells that forms the part of extracellular matrix in the epidermis. The nuclear membrane is the part of the cell. It lies around the nucleus which is the component of the cell and not of extracellular matrix.
