Plant and animal hormones. The nervous system and hormones are used to control and coordinate the body. A plant tropism is a growth in response to a stimulus. Auxins are plant hormones that control the direction of growth.

Eicosanoids: these are lipid hormones – hormones made from lipids, kinds of fats. These are mostly hormones that send messages near the cell that makes the hormones. Amino acid derived. Melatonin works on the brain, and thyroxine acts on almost all cells in the body.

Plant and animal cells contain different organelles, which are tiny structures inside the cells that perform different functions. However, both plant and animal cells serve the same basic functions. They divide over time so that plants and animals can change and grow.

Animal and plant cells have some of the same cell components in common including a nucleus, Golgi complex, endoplasmic reticulum, ribosomes, mitochondria, peroxisomes, cytoskeleton, and cell (plasma) membrane.

Hormones and Steroids Used in Cattle It can increase the amount of dairy products and beef. Some hormones that may be used in dairy cows include: Recombinant bovine growth hormone (rBGH)— to increase milk (may also be called bovine somatotropin [BST])

Cytokinins. The cytokinin hormones promote cell division and tissue growth, and depend upon the presence of auxins to determine the extent of their activity. When the ratio of cytokinins to auxins is relatively high, stem and leaf growth is stimulated.

There are two type of hormones, the water soluble amino acid based hormones and the lipid soluble steroids. Most hormones are amino acid based hormones. They can range from simple modified amino acids to polypeptides to proteins. The remainder are steroids, which are synthesized from cholesterol.

Plants and animals share many characteristics, but they are different in some respects. Animals usually move around and find their own food, while plants are usually immobile and create their food via photosynthesis. Plants and animals both have cells that contain DNA, yet the structure of their cells differs.

Soy and some other plants contain estrogen-like compounds called isoflavones or phytoestrogens. These plant estrogens are thousands of times weaker than the estrogen produced by the body, but may be present in much higher concentrations in the blood. Evidence about their safety has been mixed.

Estrogen progesterone & testosterone. A woman's body makes different hormones throughout her life. The three major sex hormones made by the ovaries are the so-called “female” sex hormones estrogen and progesterone, and the so-called “male” sex hormone testosterone.

Estrogen is the hormone that regulates the menstrual cycle while progesterone is the hormone that supports pregnancy. During pregnancy, these two work together and are responsible for the changes that take place during pregnancy.

Cells are the basic unit of a living organism and where all life processes are carried out. Animal cells and plant cells share the common components of a nucleus, cytoplasm, mitochondria and a cell membrane. Plant cells have three extra components, a vacuole, chloroplast and a cell wall.

Both plants and animals reproduce sexually, producing a male and female gamete, which fuse to form a zygote. However, plants are also able to reproduce asexually, unlike most animals.

Endocrine glands - secrete chemical substances called hormones directly into the bloodstream for transport to target tissues. There are more than 20 steroid hormones in the body, ie. cortisol, cortisone, estrogen, progesterone, testosterone.

Chemical Nature of Hormones Chemically, hormones may be classified as either proteins or steroids. All of the hormones in the human body, except the sex hormones and those from the adrenal cortex, are proteins or protein derivatives.

Phytoestrogens, also known as dietary estrogen, are naturally occurring plant compounds that may act in a way similar to that of estrogen produced by the human body. Here are 11 significant sources of dietary estrogens.
