Land plants get the water they use in photosynthesis from the soil through their roots.

Land plants obtain water for photosynthesis from the soil, which is absorbed through their roots and transported to the leaves through the xylem.

Land plants obtain water for photosynthesis primarily from the soil. The process involves a series of steps that enable water uptake and transportation within the plant. First, plant roots, equipped with root hairs, extend into the soil and absorb water through osmosis. This occurs because the concentration of dissolved substances, such as minerals, in the root cells is higher than that in the surrounding soil.

Water moves from the roots to the xylem, which is a specialized tissue responsible for transporting water and nutrients throughout the plant. This upward movement is facilitated by a combination of root pressure, capillary action, and most importantly, transpiration. Transpiration is the loss of water vapor from the plant's leaves through small openings called stomata. As water evaporates from the leaf surfaces, it creates a negative pressure gradient that pulls water up through the xylem from the roots.

Once water reaches the leaves, it is utilized during photosynthesis. The water molecules are split during the light-dependent reactions, releasing oxygen as a byproduct and providing electrons for the production of ATP and NADPH, which are essential for the light-independent reactions (Calvin cycle).

In summary, land plants rely on their roots to absorb water from the soil, which is subsequently transported through the xylem to the leaves where it is utilized in the process of photosynthesis.

Photosynthesis and aerobic respiration are two essential biological processes that are intimately connected, as they provide the basis for energy flow in most living organisms. Photosynthesis is the process by which plants and some other organisms convert light energy into chemical energy in the form of organic molecules, while aerobic respiration is the process by which cells break down organic molecules to release energy in the form of ATP (adenosine triphosphate).

The products of photosynthesis, which are organic molecules such as glucose and other sugars, serve as substrates for aerobic respiration. During aerobic respiration, these organic molecules are broken down by a series of enzymatic reactions, releasing energy that is used to generate ATP. This energy is used by the cell to carry out various metabolic processes and perform work.

On the other hand, the products of aerobic respiration, which are carbon dioxide (CO2) and water (H2O), are utilized in photosynthesis. During photosynthesis, plants and other organisms take in CO2 from the atmosphere and use it, along with water and light energy, to produce organic molecules such as glucose. This process is facilitated by a group of pigments called chlorophyll, which are located in the chloroplasts of plant cells.

Therefore, the substrates and products of photosynthesis and aerobic respiration feed into one another, creating a continuous cycle of energy flow. The organic molecules produced during photosynthesis provide the energy necessary for cells to carry out aerobic respiration, while the products of aerobic respiration are used in photosynthesis to produce more organic molecules. This cycle helps to ensure that the energy needs of living organisms are continuously met and that the environment remains in balance.

Animals perform many behaviors which are caused by stimuli, or a signal that causes an organism to react in some way. An animal's response to this stimulus may include external actions or internal changes, such as a faster heartbeat, or both.

Thus, animals perform some instinctual behaviors without being taught, but most learned behaviors result from another animal's experience. A behavior that is a combination of instinct and learning is imprinting, which can be seen in a newly hatched bird that recognizes and follows the first moving object they see.

Learning that a particular stimulus or response can lead to a good or bad outcome is called conditioning. One form is trial-and-error learning in which animals learn to perform a behavior more skillfully through practice. Sometimes past experiences can be used to solve problems, and when this occurs, animals are using insight learning.

Those messages are sent to the hand using sensory neurons.

Axons are long single fibers that carry messages from the cell body to the dendrites of other neurons or other body tissues such as muscle. In muscles, this electrical message causes them to contract or shorten. Think of catching a ball. The brain tells neurons to send electrical signals to the neuromuscular junction. This releases neurotransmitters into your finger muscles, which contract to catch the ball.

Motor neurons release chemicals that are taken up by muscle fibers. This causes the muscle fibers to contract and the muscle to move. Neurons carry messages from the brain through the spinal cord.
