Which of the following is a true statement? (Check all that apply) A) The epidermis forms from the ectodermal domain that is not exposed to BMP inhibitors. B The epidermal stem cell divides symmetrically and one of the daughter-cells goes on to differentiate into a keratinocyte. Epidermal cells move upward as they become more and more differentiated. D After the division of the basal cell, the daughter-cell that expresses Notch remains a stem celL E The integrin-laminin interaction prevents the basal cell from differentiating. The basal cell divides parallel to its apical-basal axis. G Cells found in the lower layers of the developing skin are more differentiated than the ones found in the upper layers. H p63 is a proliferation factor while Jagged is the true differentiation signal for keratinocytes. Jagged is a proliferation signal while p63 is the true differentiation factor for keratinocytes. Epidermal signals like Fgf7, FGF10 and TGF-alpha promote the differentiation of the basal cells.
Plant Structure and Growth
Roots anchor, the plant, ingest minerals and water, direct water and supplements, and store food. These are two kinds of root frameworks.
Plant Life Cycle
Plants are part of the PLANT KINGDOM, which is one of the five kingdoms of life. Plants are divided into smaller classes based on common characteristics. Certain characteristics are shared by all plants. They are made up of a large number of cells. They also make their own food through a chemical process called photosynthesis, which involves the use of water, carbon dioxide, and solar energy. They pump life-giving oxygen into the air as a by-product.
Life Cycle of Plants
All the organisms that belong to the Kingdom Plantae are known as plants. They are multicellular and eukaryotic and can synthesize their food by photosynthesis, known as autotrophic organisms. They are classified based on certain characteristics, such as the plants bear flowers; some have only naked seeds and do not contain flowers. Some plants neither have seeds nor flowers, such as ferns and mosses.
Plant Morphology and Anatomy
The study of life and organisms is biology. The cell is recognized as the basic unit of life by biology. From ancient Greek, biology is recognized. Modern biology deals with the recent developments in Science.
