explain why osmosis is important in plant and animal
Answer:
Osmosis is important in plants and animals because it allows for the absorption of water.
Explanation:
looking at some pond water under a microscope, you notice an unfamiliar rod shaped cell about 200mm long,knowing that some exceptional bacteria can be as big as this or even bigger, you wonder whether your cell is a bacterium or a eukaryote.how would you decide? if it is a eukaryote,how will you discover if it is a bacterium or an archaeon?
Answer:
Identification of an organism or cell requires to see if there is a double membrane-bound organelle like the nucleus, mitochondria, and other present or not if the nucleus is present it is a eukaryotic organism and if not present then it must be a prokaryotic cell, either bacterium or archaean.
If it is not a eukaryote there are two ways to find out if it is a bacterium or archaeon one:
Peptidoglycan (protein and sugars) is the component that makes the cell wall of the bacteria cell whereas archaeal cell walls are made up of polysaccharides. Lysis of the cell wall components to other molecules and the sample run through HPLC for finding the basic components of the cell wall.
The second method is simple to observe the habitat of the sample, as archaeons found in a harsh environment whereas bacterium can be found anywhere especially damp or aquatic environment.

what makes carbohydrates, proteins, and nucleic acids different
Answer:
Explanation:
Carbohydrates consist of single-sugar units called monosaccharides, double-monosaccharide units known as disaccharides and multiple-monosaccharide molecules that make up starches. The predominant purpose of the carbohydrates you eat is to provide fuel to your cells. Disaccharides and starches undergo digestion to reduce them to their individual sugars, and, once absorbed, they travel to the cells and tissues throughout your body to power your physical activities. Proteins consist of 20 different amino acids, mixed and matched to create a vast array of larger molecules that support every process in your body. Digestion of protein results in a pool of single amino acids that your cells incorporate into new proteins as the need arises in your body. These molecules make up muscles and organs, transmit signals between cells, constitute immune molecules, help create the new proteins your tissues require and can serve as a fuel source in a pinch. Your cells contain two types of nucleic acids, ribonucleic acid and deoxyribonucleic acid, or RNA and DNA, respectively. They differ from the other macronutrients in that they are not a source of calories in your diet, and their role is strictly to direct the synthesis of new protein molecules. Made up of units called nucleotides, the nucleic acid DNA contains the genetic blueprint that influences your personal characteristics, while the nucleic acid RNA pulls together amino acids to form new proteins as your cells need them.
Nitrogen is found in nucleic acids in the form of nitrogenous bases, which are components of nucleotides. Carbon, hydrogen, and oxygen make up carbohydrates and lipids.
What are macromolecules?Macromolecules are essentially polymers, which are long chains of molecular subunits known as monomers.
Long polymers are found in carbohydrates, proteins, and nucleic acids. They are classified as macromolecules due to their polymeric nature and large size.
Carbohydrates, nucleic acids, and proteins are frequently found in nature as long polymers.
They are classified as macromolecules due to their long chain building nature and massive size. Macromolecules are large (macro-) molecules formed by the joining of smaller subunits.
Carbohydrates and lipids are made up of only three elements: carbon, hydrogen, and oxygen. Proteins are comprised entirely of the elements carbon, hydrogen, oxygen, as well as nitrogen.
Carbon, hydrogen, oxygen, nitrogen, and phosphorus are all components of nucleic acids like DNA and RNA.
Thus, these are the basic differences between the carbohydrates, proteins and nucleic acids.

Students testing the effects of solute concentration in soil on plant transpiration noticed a significant decrease in transpiration when abscisic acid was used as the solute. Even at molar concentrations less than 0.2 M, transpiration seemed to stop almost completely.
a) Make a claim as to which structural and/or physiological component of transpiration is affected by the presence of abscisic acid.
b) Explain the reasoning that supports your claim.
Answer:
look in textbook - concept 29.6
Explanation:
Drought stress can also cause stomata to close. A hormone called abscisic acid (ABA) is produced in roots and leaves in response to water deficiency and signals guard cells to close stomata. This response reduces wilting but also restricts CO2 absorption, thereby slowing photosynthesis. ABA also directly inhibits photosynthesis. Water availability is so tied to plant productivity not because water is needed as a substrate in photosynthesis but because freely available water allows plants to keep stomata open and take up more CO2.
abscisic acid (ABA): A plant hormone that slows growth, often antagonizing the actions of growth hormones. Two of its many effects are to promote seed dormancy and facilitate drought tolerance.
The plant hormone abscisic acid (ABA) is naturally produced in response to drought situations and reduces transpiration (E) by remaining in the stomata. for that reason, ABA can also lengthen shelf lifestyles of retail vegetation by reducing water loss.
How does abscisic acid affect the outlet and remaining of the stomata?Abscisic acid (ABA) is a plant hormone involved in the response of flora to decreased water availability. Discount of guard cell turgor via ABA diminishes the aperture of the stomatal pore and thereby contributes to the capability of the plant to conserve water in the course of intervals of drought.

PassiveCellular Transport (high to low concentration)
▪Diffusion –when, why & how does it occur?
▪Osmosis –when, why & how does it occur?
▪Facilitated diffusion –when, why & how does it occur?
Active Cellular Transport (low to high concentration)
▪Active transport –when, why & how does it occur?
▪Endocytosis –when, why & how does it occur? (phagocytosis vs. pinocytosis)
▪Exocytosis –when, why & how does it occur?
Membranes
▪structure & function
▪function of pores & carrier proteins
Answer:
1 - Diffusion is when small, non-polar molecules pass through the cell membrane. It happens so that the cell can get vital nutrients, it is a type of passive transport.
2 - Osmosis is the transport of water through the cell membrane. It is a type of passive transport, the water moves to the side of the cell with less water.
3 - Facilitated diffusion is when protein channels or transports help large polar molecules like glucose that ordinarily couldn't get through the cell membrane pass through the membrane.
4 - Active transport is when a molecule requires energy, ATP, to pass through the cell membrane. An example of this is molecular pumps, the use energy, ATP, to work.
5 - Endocytosis is when a vesicle captures an outside substance for the cell. There are two types of endocytosis, phagocytosis, which is "cell eating" where the cell digests solids, the there's pinocytosis, which is "cell drinking" where the cell digests liquids.
6 - Exocytosis is when a vesicle removes a substance from the cell by combining with the cell membrane and pushing it out.
7 - The Membrane is made out of phospholipids
8 - Carrier proteins help molecules that are large and polar get into the cell.
