<h2>Answer:</h2>
<u>When a plant cell is placed in a hypo-tonic solution It becomes turgid and hard.</u>
<h2>Explanation:</h2>
A hypotonic solution refers to a solution that has less solute and more water than another solution. When the plant cell is placed in a hypotonic solution, it takes up water by osmosis and starts to swell, but the cell wall prevents it from bursting. The plant cell is said to have become "turgid" i.e. swollen and hard. The pressure inside the cell rises until this internal pressure is equal to the pressure outside.
Answer:
Heterotrophs obtain chemical energy for their survival by eating plants and animals.
Explanation:
- The chemical energy that organism need comes from food. They break this food down to obtain energy.
- Depending on their source of nutrients , they are classified into: Autotrophs and Heterotrophs.
- Autotrophs use sunlight and photosynthesize to produce their own food. They are often known as producers.
- Heterotrophs are beings that can't prepare their own food and consume other organisms to obtain energy.They are also called consumers.
- Examples include: Animals, fungi,etc.
Vegetative propagation by means of mitotic division can lead to the formation of new individuals which are then genetically identical to each other and the mother organism
Answer: It filters waste out of your body. Think of "excretory" as "expelling" something gross.
Diffusion is essential for cells to bring nutrients and releasing wastes WITHOUT spending energy. This is accomplished by the "urge" of a system to achieve equilibrium, which means that materials tend to flow from high concentration to low concentration area. For example, if a cell lacks amino acids, and therefore has a low concentration of it inside the cell compared to the outside, then by diffusion, the amino acids outside will flow in through the membrane until the concentrations of amino acids outside and inside the cell are the same. All these are done without spending energy from the cell. Note, however, that simple diffusion cannot transport larger particles or those insoluble in lipids; these materials have to be transported with facilitated diffusion, where a carrier on the membrane of the cell will help bring in the materials.
<span>Diffusion is when particles in a more concentrated area move to a less concentrated area, through a semi- permeable membrane. Without diffusion, the cells in your body will not be able to obtain the resources they need to survive, like water and proteins.</span>
