What is the significance of growth factors in biology and how do they contribute to the development and regulation of cells and tissues?
Growth factors are important signaling molecules in biology that play a crucial role in the development and regulation of cells and tissues. They stimulate cell growth, proliferation, differentiation, and survival. By binding to specific receptors on the cell surface, growth factors activate signaling pathways that control various cellular processes. This helps in maintaining tissue homeostasis, promoting wound healing, and regulating organ development. Overall, growth factors are essential for the proper functioning and maintenance of living organisms.
What is a growth factor in biology and how does it contribute to the development and regulation of cells in living organisms?
In biology, a growth factor is a protein that helps regulate cell growth, division, and differentiation. These factors play a crucial role in the development and maintenance of cells in living organisms by signaling cells to grow, divide, or specialize into specific cell types. They help control various processes such as tissue repair, immune response, and organ development, ensuring that cells function properly and the organism grows and functions normally.
What is the part of the vascular tissue that carries food?
The phloem is the part of the vascular tissue that carries food, such as sugars and other organic nutrients, throughout a plant. It transports these substances from the leaves, where they are produced through photosynthesis, to other parts of the plant for growth and energy.
What cell tissue may absorb and or secrete substances?
Epithelial tissue is a type of cell tissue that can absorb and secrete substances. This tissue covers the surfaces of the body and internal organs, forming barriers that can facilitate the movement of molecules in and out of the body.
What are the chemicals that originate and have their effects in their local tissue environment?
Autocrine factors are chemicals that originate and act within the same tissue or cell where they are produced. They play a role in cell signaling and regulation within a local environment. Examples include growth factors and cytokines.

What are the two substances transported through phloem tissue?
The two main substances transported through phloem tissue are sugars (such as sucrose) and amino acids. These substances are transported from the leaves, where they are produced through photosynthesis or other metabolic processes, to other parts of the plant for growth and metabolism.
What is the scientific definition of tissues?
The scientific definition of tissue culture originally meant the growth and maintenance of tissue pieces. Now it is more commonly referring to the technique of the cell culture.
Which life function provides substances that may be used an organism for its growth and for the repair of its tissue?
Nutrition. Why ? I am yet to find out..nutrition
What is a tumor marker?
Tumor markers are substances, usually proteins, that are produced by the body in response to cancer growth or by the cancer tissue itself.
What is tje neutriants?
Nutrients are substances that provide nourishment essential for the maintenance of life and growth. They include carbohydrates, proteins, fats, vitamins, minerals, and water, which are obtained through food and support various functions in the body, such as energy production, tissue repair, and immune system function.
What are growth characteristics of bone?
Bone growth occurs through two primary processes: endochondral ossification and intramembranous ossification. Endochondral ossification involves the replacement of cartilage with bone tissue, primarily during the development of long bones. Intramembranous ossification, on the other hand, occurs in flat bones, where bone develops directly from mesenchymal tissue. Bone growth is also influenced by factors such as age, hormonal regulation, mechanical stress, and nutritional status, contributing to the dynamic nature of bone remodeling and maintenance.
What is growth tissue that remains just behind the root tip?
The root cap is the growth tissue that remains just behind the root tip. It protects the delicate meristem as the root pushes through soil and aids in root growth by secreting lubricating substances.
What is One of a group of diseases causing substances that depends on living tissue for reproduction and growth?
Viruses - they are unable to replicate outside of a host cell.
What is the scientific definition of tissue culture?
There are four main types of tissues in animals; epithelial, nervous, muscular, and connective.
