Answer:
Following are the seven basic requirements of plants to grow properly.
1) Light: Light is the basic need of plant. With the help of light, photosynthesis occurs.
2)Water: Water is used by the plants as a reactant in making their own food.
3) Temperature: In optimum temperature, plants grow fast.
4) Time: There is proper time for the sowing of every plant.
5) Nutrients: Nutrients are food of plants which are used for their growth and development.
6) Proper place or medium: Plants require a soft nutritious soil for germination.
7) Air: Plants need air because it contains oxygen and carbondioxide which is used by the plants during photosynthesis and respiration.
Answer and Explanation:
Cell: Molecules get grouped in alive cellular units that have auto replication capabilities. It is the smallest structural unit capable of functioning by itself. A cell is capable of communicating with other cells, their membranes delimitate them and protect them, constituting a selectively permeable barrier, receives signals from the exterior and responds in different ways to the different signals. There are different cells with different sizes, shapes, and forms.
Tissue: A tissue is the organization and association of the same type of cells. Each tissue performs different functions. These tissues can be epithelial, adipose, nervous, muscular, and etcetera.
Organ: An organ is composed of different tissues that work together in a more complex function. Tissues form structures such as the heart, lung, kidney, brain, and etcetera. Each organ has its function.
Organ systems: When different organs get associated and work together, they become a system. Working together in a stable way organs maintain homeostasis.
Answer:
unicellular; multicellular
Explanation:
<em>The smallest and the most basic unit of life is the cell. Living organisms that are made of just one cell are said to be </em><em>unicellular </em><em>while those that are made up of multiple cells are said to be </em><em>multicellular.</em><em> Many unicellular organisms are some of the smallest living organisms to exist in nature. They cannot be seen with the ordinary eyes, except with the aid of microscopes.</em>
